How to make a perfect plastic injection mold and injection molding is always our goal.

Rusting of plastic molds is a normal phenomenon and  caused by special reasons.It is not always due to quality problems of steel products. Melt Decomposition Some plastic raw materials will release volatile gases after being heated, which are corrosive and corrode the mold steel. Therefore, when the injection machine stops , wipe the mold clean …

Storing Molds During downtime, plastic molds are generally removed from the molding press and put into some kind of maintenance. The mold warehouse  usually has s few heavy-duty steel shelves where the molds are positioned onto ,and labeled for identity. Generally, the mold contains particular identity engraved on perhaps 2 adjacent walls so it’s easily …

SAFEGUARDING THE MOLD Molds are very pricey tools. They might need many hundreds (and perchance thousands) of hours of engineering and creating prior to they are prepared to be applied for manufacture requirements. Destroyed molds lead to financial obligations to the molder and consumer, not only in fix expense, but in dropped fabrication and machine …

It is safe and sound to mention that any plastic mold will need a great amount of fix for deterioration taking place throughout the utilize or storage of that mold. The harder it is employed, or the longer it is kept, a lot more damage will happen. Damage that happens at the time of employ …

Plastic material identification Judging thermoplastics and thermosets: All thermosets have no softening process when heated or burned, only become brittle and coked; All thermoplastics, which are heated or burned, undergo a soft melting process, but different plastics burn. The phenomenon is different. pp PP burns slowly, the upper end of the flame is yellow, the …

Gas-assisted injection molding is an innovative technology developed on the traditional injection molding . GIM (Gas-assisted injection molding) was adopted in production  since 1980s. The gas-assisted injection molding system directly injects inert gas (usually nitrogen) into the melt plastic in the mold cavity through the sectional pressure control system, which makes the plastic part expand …

There are many classification for plastic injection molds. According to the basic injection mold gating system, it can be divided into three types: Two-plate mold; Three-plate mold; Hot runner mold, also called runner-less mold. Other plastic molds, such as side core pulling mechanism,  core-unscrewing  de-molding mechanism,  are evolved from these three types of molds.   …

Hot runner system can be seen as an extension of injection molding machinery. The function of the hot runner system is to thermally insulated to send the thermoplastic melt to the plastic mold. The hot runner can be heated independently while it is thermally insulated in the injection mold, which can compensate for heat loss …

The Difference between insert molding and Double Color molding The so-called two-color injection molding refers to the molding method of injecting two kinds of plastics with different colors into the same mold. It can make the plastic parts with two different colors, and can make the plastic parts show regular patterns or irregular patterns, so …
