Cautions in Mold Tryout

Mold tryout is to test the mold defects through different process conditions and improve it through modifying. For those that cannot be modified for the time being, it is necessary to find out the most reasonable process parameters to guide the subsequent injection molding production.

 

Pay attention to the following content during the mold tryout:

First: Check the flow balance

Observe the product’s glue feeding by gradually increasing the amount of glue. For a single cavity, flow balance means that the flow front of the melt reaches the end of the cavity. For multiple cavities, flow balance means that the flow front of the melt reaches the end of each cavity . Different product weights or inconsistent shrinkage in multi-cavity molds in injection molding production are generally caused by imbalanced flow.

Second: The inspection of flashing

Check if the parting surface, row position, insert joint line, ejector pin hole and other parts when the product is not shrunk. In this case, more injection molding needs to be adjusted Process, local glue reduction, increase gate or change gate position to improve.

Third: Determination of mold exhaust position

Use a faster injection speed to find the position where the product has scorched, trapped air, water traps, etc., and then set up an exhaust slot at the corresponding position.

Fourth: Determine the key position of the screw of the injection molding machine

By changing the stroke of the screw of the injection molding machine, determine the key position of the screw during product injection. At a minimum, the key positions should include:

  1. The flow channel has just been filled;
  2. From the first gate filling to the last gate filling position (unbalanced gate design);
  3. The location when the water line, burnt, trapped air and other undesirable phenomena that affect the product appear;
  4. The position when the product is 99% filled (that is, the speed and pressure conversion position).

These key positions are the key to adjusting the injection process in the future.

Fifth: Inspection of product appearance
  1. Check the appearance of bad phenomena caused by mold manufacturing, including: piercing, mold surface not smooth, mold surface uneven, mold printing, step difference, poor etching, top white, drag, sticking, etc.
  2. Check the appearance defects caused by the injection molding process, including: air lines, water lines, watermarks, scorching, shrinkage, lack of glue, top white, scratches, material flowers, deformation, etc.
Sixth: Inspection of product size

By adjusting the injection molding process, when the product has a better appearance, a preliminary inspection of the appearance size of the product is carried out. When the size and appearance are restricted, the following principles are followed:

  1. If the product size is too small, the injection molding process should be adjusted until the appearance of the product appears top white, top height, drag, and mold sticking, and find the maximum size that the injection molding process can adjust.
  2. If the product size is too large, the injection molding process should be adjusted until the appearance of the product shrinks, lack of glue, etc., and find the smallest size that the injection molding process can adjust.

As long as this can be done during mold tryout, and the mold problem is discovered and solved. It will provide great convenience for subsequent injection molding production. If you don’t do this during mold trial, the problems in the mold are not found or resolved, and the mold is produced with defects. Not only will the production not proceed smoothly, but the production cost will also be very high.

Five tips for mold design-Xiamen Huaye Precision Moulding

Five Tips for Mold Design

When producing a plastic part, it is hard to make it perfect. Only after the design in the early stage can more problems be avoided in the later stage. Plastic product design plays a connecting role in avoiding many problems.

1) Comparing raw materials

Choose the right material among many materials, the first thing is to compare their performance, characteristics and cost,etc.

When the material’s use temperature is closer to its melting point, the temperature and time will directly affect the deformation performance of the raw material.

The characteristics of plastics are not only the one of pure raw materials. If the raw materials are processed in the inapplicable range, the best design will fail. Similarly, products cannot solve design weaknesses through processing. Therefore, only an optimized process that takes all factors into consideration can ensure the quality of plastic parts.

2) Design checklist

The goal of new product development or improvement is to make excellent performance at low production costs. The design tasks mainly include raw material and processing method selection, strength calculation and mold design.

Only when these factors are fully considered and systematically followed up can we produce high-quality, commercially-effective molds. We also have to emphasize that the practicality and cost efficiency of plastics are not inevitable, and designers must pay great attention to the selection of raw materials and correct solutions for the processing process.

3) Consider the gate design

The designer not only has to calculate the product design, but also must pay special attention to the gate design of the mold. They must choose the correct gate system and the number and location of gate points. Different gate types and positions will have a greater impact on the quality of products.

The selection of gate location will determine the following properties of plastic products:

Filling effect;

Final size of the product (tolerance);

Shrinkage, warpage;

Mechanical performance level;

Surface quality (appearance);

If the designer chooses the wrong gate, it is almost impossible to correct the consequences from optimizing the processing parameters during the molding process.

Basic design principles:

Do not place the gate in a high pressure area;

Try to avoid or reduce the fusion line;

Try to keep the fusion line away from the high pressure area;

For reinforced plastics, the gate position determines the warpage performance of the part;

Provide adequate exhaust ports to avoid air trapping.

4) Basic assembly process

Some simple assembly techniques recognized by all designers, such as snap assembly, press assembly and thread assembly, etc., can greatly save production costs by simply and quickly assembling components.

The biggest advantage of snap assembly is that no additional assembly parts are needed. In the buckle design, the designer must ensure the geometric dimensions of the accessories to avoid stress relaxation causing loose assembly components.

Press assembly can make plastic components high-strength assembly at the lowest cost.

The thread assembly consists of the use of separate, combined screw or integral screw inserts. In order to avoid the production of unqualified components, ensuring the correct sleeve size is a key part. Screw manufacturers can make many suggestions in this regard.

5)Cost-saving design

Designers bear most of the responsibility for the final cost of plastic parts. Their decision predetermines the cost of production, mold making and assembly. Later corrections and optimizations are usually expensive and infeasible.

Making full use of the advantages of the characteristics of plastic raw materials can save costs in many ways. Multifunctional integrated design, low-cost assembly technology (such as buckle, welding device, fixing device, two-material injection molding technology, etc.), use of self-lubricating properties, and no surface treatment procedures. Paying attention to wall thickness, molds, tolerances, raw materials, etc. can further save costs.

When a product is to be produced, it is mainly for profit, which is to reduce the cost of the product. The designer has an inseparable relationship with the final cost of the part. His decisions, ideas and final design are all related to the cost of the product. Make good use of the characteristics of plastics to control the cost. Considering some technologies in the mold, it can also reduce costs to a certain extent.

The layout principle of ejector pin from Huaye Precision Moulding

The layout principle of Ejector Pin

Ejector pins are the “bouncers” of the injection molding world. They apply a force to eject a part from the mold, and in some cases can leave marks. … Once the mold is opened, the pins extend into the mold cavity, push the part out, and then retract, allowing the mold to close and be refilled.

The ejection of a plastic product is the last step in the plastic injection molding process. The quality of the ejection determines the quality of the plastic product. When the mold opens, the plastic product must be retained on the mold half (usually the core) with the ejector mechanism that is used to release the plastic product.

     1.The ejector pin layout should make the ejection force as balanced as possible

The demolding force for complex structures is relatively large, so the number of ejectors should be increased accordingly.

  1. The ejector pin should be set in effective places

The effective places include the rib, column, step, metal insert and other complex structures. The ejector pin on both sides of the rib and column should be arranged symmetrically as much as possible. In addition, try to ensure the ejector pin on both sides of the column position.

  1. Avoid arranging ejector pinon the inclined surface or overstepping

The top surface should be as smooth as possible, and we should arrange it in the structural part of the rubber with better force.

  1. Flat ejector pin should be chosen in some cases

In the deep rib (depth ≥20mm) or it is difficult to arrange the dome ejector pin, we should adopt flat ejector pins. When we use it, try the insert form to facilitate processing.

  1. Avoid sharp and thin steel

When layout the ejector pin, we should avoid those sharp and thin steel. And the top surface of the ejector pin should not touch the cavity side.

  1. Consider the distance between the ejector pin and the waterway

Avoid affecting the processing and water leakage of the waterway.

  1. Consider the exhaust function of the ejector pin

In order to exhaust during ejection, it should be arranged in the part which is easy to form a vacuum. For example, in the larger plane of the cavity, although the packing force of the rubber part is small, it is easy to form a vacuum, which leads to an increase in the demolding force.

  1. The ejector pins cannot be placed in some places

For plastic parts with appearance requirements, it can not be in the appearance surface, and we should adopt other ejection methods. For transparent plastic parts, it can not be arranged in the part that needs to transmit light.

Practical Precaution for Using Calipers

Practical Precautions for Using Calipers

The caliper is one of the most common measuring tool in the toolbox. It has many advantages such as multiple measurement modes, easy operation, durability, strong versatility, and low cost. However, there are still many precautions to use calipers correctly. Let’s start with the error factors that affect the measurement results.

Error factor

When measuring with calipers, there are many factors that cause errors, such as parallax, errors caused by the structure not conforming to Abbe’s principle, thermal expansion caused by the temperature difference between the caliper and the workpiece and so on.

In addition, because the caliper has no constant pressure device, it is difficult to grasp a suitable and uniform measuring force when measuring, which is another error factor.

1. The structure of the caliperdoes not conform to the Abbe principle

The reading and measuring axis of the caliper do not conform to the Abbe principle because of the different axes. Therefore, when using the caliper, measuring with the root or tip of the claw may increase the measurement error. When measuring, pay attention to the measured workpiece as close to the ruler body part (reading axis) as possible.

2. Read the parallax of the scale

When checking whether the vernier tick mark is aligned with the main tick mark, look directly at the vernier tick mark.

Practical Precaution for Using Calipers

There is a step height between the vernier ruler and the main ruler scale surface, which is easy to cause reading errors. As shown in the figure below, if you observe the vernier scale line from an oblique direction, the error shown by ΔX in the figure will occur. In order to avoid the influence of such factors, the JIS specification stipulates that the step height (H) should not be greater than 0.3mm.

3. The bending of the reference end face

If the ruler surface that guides the sliding of the vernier is bent, it will cause the error shown in the figure below. This error can be expressed by the same calculation formula as the error that does not conform to the Abbe principle.

Practical Precaution for Using Calipers

Example: Suppose the deformation caused by the bending of the guide ruler surface is 0.01mm/50mm, and the outer diameter measuring claw tip is 40mm to calculate: f=40mm×0.01÷50=0.008mm

4. Relationship between measurement and temperature

Caliper is generally made of stainless steel, which has the same thermal expansion coefficient (10.2±1)×10-6/K as ferrous metals. The material of the measured object, the room temperature and the temperature of the workpiece must be considered when measuring.

5. Notes on operation

The caliper claw is very sharp, so the instrument must be operated carefully to avoid personal injury.§

Avoid damaging the scale of the digital caliper, do not engrave the identification number or use the electric pen to leave other information.

Avoid colliding with hard objects or falling on the stool or floor to damage the calipers.

6. Maintenance of sliding surface and measuring surface

Before using the caliper, wipe off the dust and dirt on the sliding surface and the measuring surface with a soft dry cloth.

7. Check and calibrate the origin before use

Clamp a piece of clean paper between the outer claws, and then slowly pull it out. Before using the caliper, close the measuring jaw and make sure that the vernier scale (or display) returns to zero. When using a digital caliper, please reset (zero button) after replacing the battery.

8. Operation after use

After using the caliper, wipe off water and oil thoroughly. Then, lightly smear it with anti-rust oil, dry it before storing.

Waterproof calipers, in order to prevent rusting after use, also need to wipe off the moisture of the calipers.

9. Precautions for storage

Avoid direct sunlight, high temperature, low temperature and storage in high humidity environment.§

If the digital caliper is not used for more than three months, remove the battery before storing.

During storage, do not allow the outer measuring jaw of the caliper to be completely closed.

How to solve the difficulty of Demolding by injection mold manufacturer

How to solve the difficulty of Demolding

After the plastic part is injection molded, it is ejected from the mold cavity, whether it is a single or multi-element ejection mechanism, the demolding work is generally completed at one time. But sometimes due to the special shape of the plastic part or the needs of production automation, the plastic part is still difficult to take out from the cavity or cannot fall off automatically after one demolding action. That means we need to make another demold to fall off the plastic part.

And there are some reasons for causing the difficulty of demolding in certain aspects:

1.Equipment:

(1)Insufficient ejector force.

2.Mold:

(1) Unreasonable demoulding structure or improper position.

(2) The draft slope is not enough.

(3) Mold temperature is too high or poor ventilation.

(4) The runner wall or cavity surface is rough.

(5) The nozzle does not conform to the mold inlet or the nozzle diameter is larger than the inlet diameter.

3.Process

(1) The barrel temperature is too high or the injection volume is too much.

(2) The injection pressure is too high or the holding and cooling time is too long.

4.Raw materials

(1)Insufficient lubricants.

How to solve the difficulty of Demolding by injection mold manufacturer

The traditional demoulding methods of plastic molded parts are roughly divided into four types: ejecting, pushing, pulling and rotating.

Now there is a new demoulding technology that can easily solve the problem of plastic demoulding. In the plastic mold industry, there are many unsolvable problems, especially when a variety of resin compounds are for highly complex designs and high-gloss finish processing.

Nano demoulding coating can form a coating on the surface of the plastic mold or even on the surface of the insert of the plastic mold, which can significantly reduce the friction coefficient of these surfaces, and a highly glossy processing surface can be achieved without using traditional mold release agents. Nano demoulding coating not only improves the smoothness and accuracy of the plastic mold surface, but also greatly improves the productivity of the plastic mold manufacturing industry!

Principles of Designing Parting Surface

Principles of Designing Parting Surface

In the design of precision injection molds, the parting surface is to take out the molded plastic parts from the mold cavity and to meet the needs of insert placement and exhaust. According to the structure of plastic parts, the part of the mold is divided into several parts of the contact surface. Precision molds have higher precision requirements than ordinary molds, so the design of the parting surface is critical, and the results will directly affect the mold structure, processing difficulty and the costs. Because different design has different results even in the same product, so it does have some difficulty.

Principles of Designing Parting Surface

The competitive advantage of Xiamen Huaye Precision Mould(XHPM) over other injection mold manufacturers is that we have a complete set of design principles for parting surfaces. The mold design of XHPM is more efficient and cost-effective.

Now I will introduce the design principles of XHPM:

  1. The parting surface should be selected at the largest contour of the plastic part.
  2. The parting surface cannot be selected between the smooth surface and the apparent surface, so as not to affect the appearance quality of the parts.
  3. The parting surface should be conducive to exhaust. It is the main exhaust channel in a mold. We should place it at the end of the plastic melt flow direction as much as possible, and consider the design of the pouring system at the same time.
  4. The parting surface should facilitate lateral core pulling, and we had better to place the lateral core pulling mechanism on the side of moving mold.
  5. The parting surface should facilitate the demoulding of the plastic parts. Since the ejector is on the side of the moving mold, It should be as far as possible to keep the plastic parts on the side of the moving mold after opening the mold. This helps to set up the pushing mechanism in the moving mold part. If the pushing mechanism is set in the fixed mold, it will increase the complexity of the mold.
  6. The parting surface should facilitate processing and manufacturing. The cost, accuracy and a large part of the injection mold depend on the selection of the parting surface.

Plastic injection mold maintenance of injection mold manufacturer

Plastic Injection Mold Maintenance

As the most important part for the injection molded products, injection molds are directly related to the product quality. Moreover, since the mold occupies a large proportion of the cost of the injection processing, its service life also affects the product price. Therefore, improving the quality, maintaining them well and prolonging their life is very necessary for the manufacturer. And you’d better choose a reliable mold supplier. It is helpful that the factory has its own processing equipment and test machine, so that the efficiency will be high.

Due to the variety of products and the frequent replacement of molds, the molds are generally stored until the next production cycle. However, some factories do not pay enough attention to the preservation of the mold, which causes corrosion and reduces the surface finish during the storage period, resulting in a decline in product quality. Some molds are even unable to reuse again, and maybe need to make another mold which causes great waste.

The technology of injection mold is very high, and there are many kinds of components. If you don’t take the maintenance seriously, it will be easily damaged and cause thousands of economic losses. Therefore, special attention should be paid to the maintenance and of the mold during use to ensure the long-term quality of the mold.

Therefore, the maintenance of injection molds is pretty necessary.

Plastic injection mold maintenance of injection mold manufacturer

Plastic injection mold maintenance of injection mold manufacturer

At first, equip each mold with a resume card.

It is to record and count its use and damage in detail. According to this, we can know which parts and components have been damaged and the degree of wear and tear, to provide information for finding and solving problems, In the card, there are the molding process parameters, and the used material, which help us shorten the test time of the mold and improve production efficiency.

Secondly, test the mold performances under the normal operation.

Measure the size of the final molded plastic part. We can determine the mold state and the cavity and core can be found. , The damage of the cooling system and the parting surface, etc., according to the information provided by the plastic parts, you can determine the damage state of the mold and maintenance measures.

Thirdly, track and test the important components.

The function of the ejection and guide parts is to ensure that the mold opens and closes and the plastic parts are ejected. If any of them are stuck due to damage, it will lead to production shutdown. Therefore, you should always check whether the ejector rod and guide post are deformed or damaged. , Once found, it should be replaced in time. After the completion of a production cycle, anti-rust oil should be applied to the moving and guiding parts, especially the protection of the bearing parts with gears and rack molds and the elastic strength of the spring molds to ensure that they are always in the best working state. In addition, the cleaning of cooling channels is of great importance to production efficiency and product quality.

As the production time continues, the cooling channel is prone to deposit scale, rust, sludge, algae, etc., making the cross section of the cooling channel smaller and the cooling channel narrower, greatly reducing the heat exchange rate between the coolant and the mold, and increasing the production cost of the enterprise. Therefore, attention should be paid to the cleaning of the flow channel.

Fourthly, pay attention to the surface maintenance of the mold.

It is directly affects the surface quality of the product, and the focus is on preventing corrosion. After the mold completes the production task, different methods should be used to carefully remove the residual injection according to different injections. Copper rods, copper wires and soapy water can be used to remove the residual injection and other deposits in the mold, and then air dried.

It is forbidden to clean hard objects such as iron wire and steel bar to avoid scratching the surface. If there are rust spots caused by corrosive injection, use a grinder to grind and apply anti-rust oil, and then store the mold in a dry, cool and dust-free place.

A pair of high-quality molds can shorten the time of mold assembly and commissioning, reduce production failures, smooth production operations, ensure product quality, reduce waste loss, and reduce the company’s operating costs and fixed asset investment. When the next production cycle begins, Enterprises can successfully produce qualified products.

Therefore, for injection molding product processing companies, under the current fierce market competition, maintaining good molds can help the company.

Key points of mold installation&uninstallation

Key points of mold installation&uninstallation

Mold installation and uninstallation plays a pretty important role in injection molding. Xiamen Huaye Precision Moulding Co.,Ltd is a professional injection mold manufacturer, and we have full experience of it. So here are some key points that we should pay attention to when install the plastic mold.

Key points of mold installation&uninstallation

First: Preparation of the mold installation

1) Check whether the material has been baked, if not, it must be baked at first.

2) Check whether there is available machine, if the machine size and the ejection is suitable, and whether the required special functions are available.

3) Check if the mold is ready, if it is, operator should immediately report and wait for the notice.
