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

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

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

【two】How to choose between two-color injection molding and in-mold injection moldinghttps://doi.org/10.1016/j.jmapro.2024.02.021 B. Products with multi-colored appearance and no surface treatmentThe 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,
01 The meaning of draft angle Structural design of plastic parts: draft angle Draft angle, as you can tell from the literal meaning, is the angle designed for the mold. To be precise, it is the mold ejection angle of the surface of the molding part in the direction parallel to the mold ejection direction,

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. Structural design of plastic parts: chamfering Chamfering refers to connecting two curved surfaces of a part at an angle

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,
Do you know how to design a plastic part embedded in a nut If: there is no problem in the selection of plastic and nut, the standard state of the nut after being embedded in the plastic is shown in Figure (I)If: the nut size is too small, the plastic BOSS hole is too large,
