Plastic molding process and mold design Plastic molding technology and mold design Important conditions for molding high-quality plastic parts: advanced mold design, high-quality mold manufacturing, high-quality mold materials, reasonable processing technology and modern molding equipment Classification according to different molding methods of plastic parts: injection mold, compression mold, injection mold, extrusion mold, pneumatic molding mold …
1. The mold length must be less than the spacing of the column to put the mold in smoothly. If the mold length is greater than the spacing of the column, if the width and height of the mold are both less than the spacing of the column of the machine, it is also possible …
Four tips to improve the precision of thin-wall injection molding The application range of plastic parts is becoming more and more extensive, from simple tableware and kitchen utensils to complex mechanical parts and electronic product shells. However, for plastic parts with high precision requirements such as electronic product shells, the precision requirements should be paid …

Why do plastic products crack? Do you know the reason? There are mainly the following reasons: Processing Excessive processing pressure, too fast speed, more filling, injection, and long holding time will cause excessive internal stress and cracking.Adjust the mold opening speed and pressure to prevent demolding cracking caused by rapid strong drawing of the parts.Appropriately …

【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 …
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 …
