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 […]

The Importance of Design For Manufacturability

In the Wikipedia, here is the introduction of  DFM(Design For Manufacturability): Design for manufacturability (also sometimes known as design for manufacturing or DFM) is the general engineering practice of designing products in such a way that they are easy to manufacture. The concept exists in almost all engineering disciplines, but the implementation differs widely depending on the manufacturing technology. DFM describes […]

Mold Temperature Influence on Plastic Molded Parts

We know that plastic parts are formed, cooled and solidified in the mold. And every resin’s glass transition temperature requirements are different, so there must be a mold temperature adjustment system. The mold temperature adjustment refers to cooling or heating the mold. It is not only related to the plastic parts quality, but also the […]

How to improve the stress mark in plastic molded products

We often see some shiny stress marks on the surface of plastic molded products and the raw materials such as ABS, PP, PC. There are several kinds of stress marks: thimble stress marks, insert stress marks, and wall thickness difference stress marks. But do you know how do they form? These apparently bright and white traces are the result of internal stress, which includes the  orientation […]

Plastic Injection Mold Classification

There are many kinds of mold classification, we can divide the mold into four different types: Mold Hardness, Quality, Difficulty and Size. Mold Hardness: Soft mold, Hard mold 1) Soft mold: The mold steel is pre-hardened without requiring quenching treatment, but the hardness is low and the HB is below 400. The mold life is within 500,000 times, and […]

How to improve the Mold Life

To improve the mold quality, it is necessary to select materials reasonably, and adopt the corresponding heat treatment process and optimized processing technology for different materials, which can improve the manufacturing accuracy and service life of the mold and avoid the early failure of the mold. This article is mainly to analyze the factors that […]

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 […]

Advantages of Multistage Injection Molding Process

Multistage injection combines the advantages of high-speed and low-speed injection so that it can give full play to the injection molding performance. It also adapt to complex products processing and the flow changes of runners and cavities. And it can eliminate the defects such as shrinkage, air traps and sink mark. Here we will talk […]

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 […]

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. First: Preparation of the mold installation 1) Check […]
