The cooling time of the part usually refers to the period of time from when the plastic melt fills the cavity of the injection mold until the part can be opened and taken out. The time standard for taking out the part by opening the mold is often based on the part that has been fully cured, has a certain strength and rigidity, and will not be deformed and cracked when the mold is opened and ejected.
There are many reasons for the sticking and poor demoulding of injection molding products, and mold failure is one of the main reasons. The causes and treatment methods are as follows:
Plastic products are very common in production errors, and there are various color products. However, during the injection molding process of the same batch of products, the phenomenon of color deviation is often found. What is the reason for this? How to solve it? Today, the editor of Huanke Precision will answer this question for you.
Plastic molds require various pressures during injection molding to complete injection molding, and finally form finished plastic parts. Today we will focus on introducing various pressures encountered in the process of plastic parts processing.
Many medical devices are made of plastic materials. Compared with metal materials, plastic materials have unique advantages and can be better applied to various scenarios of medical treatment. Among them, ABS materials are used more. ABS has certain rigidity, hardness, impact and chemical resistance, radiation resistance and ethylene oxide sterilization resistance. The medical application of ABS is mainly used as surgical tools, roller clips, plastic needles, tool boxes, diagnostic devices and hearing aid shells, especially the shells of some large medical equipment.
Mold temperature refers to the mold cavity surface temperature in contact with the product during injection molding. Because it directly affects the cooling rate of the product in the mold cavity, and thus has a great influence on the intrinsic performance and appearance quality of the product. In this paper, five points of influence of mold temperature on quality control of injection parts are discussed. The content of the package material system for excellent products is adopted for friends' reference
