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

The use of precision plastic molds is very extensive, not only high precision, but also very favorable in terms of price. However, the cooling rate has not been improved, and what are the main reasons? Briefly speaking,1. Precision plastic

​The production cost of the mold refers to the sum of the expenses paid by the enterprise for the production and sale of the mold. Mold production costs include raw material costs, purchased parts, external parts, equipment depreciation

Acrylonitrile Butadiene Styrene (ABS)Specific gravity: 1.05 g / cm 3 Molding shrinkage: 0.4-0.7% Molding temperature: 200-240 ° C Drying conditions: 80-90 ° C 2 hoursMaterial performance:1. Good comprehensive performance, high impact

Polystyrene (PS) Specific gravity: 1.05 g / cm3Molding shrinkage: 0.6-0.8%Molding temperature: 170-250 ° CDrying conditions:Material performance:Excellent electrical insulation (especially high-frequency insulation), colorless and transpare

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

The mould must be maintained every time it is used, in addition to regular maintenance, we need to check and clean the groove, correct the damaged and worn parts. For appearance maintenance: paint the outer side of the mold base to avoid rust. After running, t...

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

The requirements for PMMA injection molds are relatively high, and the surface should be high-gloss and there can be no process defects, but PMMA products are generally thicker, so there are often trapped air and product bubbles in the injection mold.

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...

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

When developing products or trial production of new products, some users often only focus on product research and development at the initial stage, neglecting communication with plastic mold manufacturers.After the product design plan is initially
