First, plastic mold after the completion of molding product appearance, size, cooperation 1, product surface does not allow defects: lack of material, burning, top white, white line, peak, foaming, whitening (or cracking, pulling), baking, wrinkles. Fuse marks: general circular perforated fuses length is not greater than 5mm, shaped perforated fuses length is less than 15mm,…
1. Plastic material The complexity of the properties of plastic materials determines the complexity of the injection molding process. The performance of plastic materials varies greatly according to different varieties, different brand sizes, different manufacturers, and even different batches. Different performance parameters can lead to completely different molding results. 2). Injection temperature The melt flows…
What are the characteristics of injection molds? Compared with plastic mold polishing processing, injection mold mirror polishing processing will be a little more difficult, although its demand is not as large as plastic mold polishing, but there are still many customers need to often process the mold. Today, let’s say what are the characteristics of…
The medical industry has considerable requirements for the application of materials. Because of this, glass is still the most important application material in many medical fields, and blood test tubes required for medical applications are one of the typical materials. Medical blood test tubes require a high degree of smoothness, transparency and dimensional accuracy, so…
Special machining: refers to some new machining methods other than cutting. Electrical regulation: Pulse power supply provides an optional set of electrical parameters such as pulse width, pulse gap and peak current for electro spark forming processing. Effect: In the process of electric spark processing, the phenomenon of different amount of electrocution due to the…

In the process of precision plastic mold processing, the choice of materials as the basis of the whole process is very critical, on the one hand to meet the actual working conditions, on the other hand, but also to meet the requirements of process performance, of course, can not ignore the…
Plastic mold processing and manufacturing, precision mold processing for plastic products and plastic molding equipment are essential, in order to be able to produce high-quality plastic products, as well as to maximize the life of the equipment, plastic mold processing and manufacturing generally need to meet some requirements. Plastic mold processing and manufacturing requirements for…
(l) The processing of the flow groove: in the past, the precision mold processing of the oil-sealed mold groove has not been paid sufficient attention to, the flow groove is often processed too far away from the cavity or the size is not easy to control, making the product pruning difficult, the product is not…
(1) The stamping parts of the design must meet the product usage and technical performance, and can be easily assembled and repaired. (2) The stamping parts of the design must be conducive to improving the utilization rate of metal materials, reducing the variety and specifications of the material, as far as possible to reduce the…
