QX Mould injection mold cooling system design1, The distance between water line and parting line should be more than two times water diameter or 15mm.2, The distance from water line to screw, ejection pins should be at least 5mm except for

Steel selection is the key.Regarding the small plastic molds, due to the high cost of production and the low cost of materials, it is preferable to use steel with good process performance, stable performance and long service life in the pro

1. Heat resistanceWith the emergence of high-speed molding machinery, plastic products production goes faster. Since the molding temperature is generally between 160 ~ 350 ℃, some poor mobility, fast forming speed, forming part of the mold

Injection mold cooling water leakage is a frequent occurrence, for many reasons, mainly in the following areas.1. Most occur in the mold cooling water pipe joints, if have water leakage, should use tape bind the pipe joint thread, and then

In our life, there are many common items of shells are basically made of plastic, such as mobile phone shells, refrigerator shells, computer shells and so on. These are produced by injection molding methods. Because these shells are direct

Due to the high requirements for the accuracy of manufacturing and processing of injection molds and the relatively complex production and processing technology, the processing and production costs of injection molds for general plastics are relatively high. P...

With the development of the times, the progress of science and the continuous updating of multimedia technology, the traditional CRT in the TV industry is gradually eliminated, replaced by LCD and LED TVs with novel appearance, ultra-thin volume

In the injection mold processing process, there are so many fixed processes that need to be used, including CNC machining, EDM machining, etc., so today we will talk about what EDM machines are like and what they do. EDM for short, EDM is a kind of m...

There are many types of plastic molds, how are they classified? (1) Injection molding is to add plastic to the heating barrel of the injection machine. The plastic is heated and melted. Driven by the screw or plunger of the injection machine, it enters

For high-precision plastic parts, when it is difficult to grasp the shrinkage rate, the following methods are usually used to design the mold: 1. Use a smaller shrinkage rate for the outer diameter of the plastic parts, and a larger shrinkage rate for

Due to the volume change caused by crystallization in the plastic injection molding process, the pressure during injection molding is high, the melt viscosity difference is small, the interlayer shear stress is small, and the elastic rebound after demolding is...

Will the injection mold be put into production immediately after completing? The answer is of course no, because there is still a very important part-trial test. The trial mold is an indispensable part, and the result of the trial mold will directly

Injection mold manufacturing can be roughly divided into the following steps: First, Process analysis of plastic products Before the mold design, the designer should fully analyze and study whether the plastic product conforms to the principle of injection mol...

In the vast field of plastic molds, fully automatic unscrewing molds stand out due to their ubiquity and criticality, becoming an indispensable part of many mold structures. Like a skilled craftsman, ...
