What are the important factors affecting the quality of injection molds?

Mold manufacturing is a complex process, from design, processing, assembly, debugging and other steps to the final actual use. During the entire life cycle, the factors that affect the quality of the mold are mainly the following. ① Requirements for injection molding materialsDifferent plastics should use different steels, such as requirements for high polishing, corrosion […]

How To Set The Filling Stage Process Of Injection Molding

The program control of the injection speed is to divide the injection stroke of the screw into 3 to 4 stages, and use the appropriate injection speed in each stage. For example: slow down the injection speed when the molten plastic first passes through the gate, use high-speed injection during the mold filling process, and

Six scientific steps to optimize the injection molding process

1) Viscosity curve The purpose of making a viscosity curve is to select a suitable injection speed injection molding process . When there are slight fluctuations in various parameters, it will not cause a large change in melt viscosity. The fluctuation between each mold should be as small as possible to ensure the repeatability of

The essential difference between two-color injection molding and in-mold injection molding

【two】How to choose between two-color injection molding and in-mold injection molding​https://doi.org/10.1016/j.jmapro.2024.02.021 ​B. Products with multi-colored appearance and no surface treatment​The appearance material is hard glue in multiple colors and does not undergo surface treatment. Most of them are used in light-transmitting products.For example: keyboard buttons, mouse, mobile phone protective case, etc. As shown below: C,

Structural design of plastic parts: chamfering

The most commonly used chamfers are divided intoRoundandchamferRounding refers to connecting two curved surfaces of a part tangently through a rounded surface. A standard rounded corner usually uses a radius value R to represent its size.

Injection molding machine electrical system, hydraulic system, mold clamping part, injection molding part maintenance points

Injection molding machine production generally operates 24 hours a day. For machines that are in working condition for a long time, we must do a good job in maintenance and strive to find and solve problems before the machine breaks down. Otherwise, once the machine fails, production must be stopped and repaired, affecting production. Therefore,

Injection molding process of polyethylene PE

PE is a crystalline raw material with very little hygroscopicity, no more than 0.01%, so there is no need for drying before processing. PE molecular chains have good flexibility, small forces between bonds, low melt viscosity, and excellent fluidity. Therefore, thin-walled long-flow products can be formed without too high pressure during molding. The shrinkage range
