In order to improve the mold performance, many manufacturers will properly process their molds. Mold processing refers to the processing of forming and blanking tools. In addition, it also includes shearing molds and die-cutting molds. However, in many cases, the molds are processed. It will also reflect processing defects, resulting in a decline in mold […]

Clamping force refers to the force applied to a mold by the clamping unit of an injection molding machine. In order to keep the mold closed, this force must oppose the separating force, caused by the injection of molten plastic into the mold. The factors that affect the specific clamping force of the mold are […]

Polyamide resin, PA for short, commonly known as nylon, is a macromolecular main chain repeating unit containing amide groups in the polymer of the general name. It is the the largest output, the most varieties, the most versatile species for the five engineering plastics . The main species are nylon 6 and nylon 66, the absolute dominance […]
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 […]
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 […]
Most of injection molds are made of chisel tool steel. During the molding, it encounters corrosive gases, water and other substances that cause rust. And Plastic parts made from rusty molds will have quality problems, so we need to know how to avoid the rust. Here are the causes and solutions of the rust: Gas from melt […]
During the injection molding process, sometimes the change in weight and size of injection parts exceeds the production capacity of the mold, injection molding machine and plastic combination. Here are the possible reasons and following remedies: Possible reasons for the problems (1) The plastic in the injection cylinder is uneven. (2) The temperature or fluctuation […]
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 […]
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 […]
