What Should We Do When Making High-precision Injection Molding Thread

Many injection molding manufacturers will communicate with customers about the problem that the precision of injection molding thread does not meet the standard when making high-precision threads. They are eager to know if there is any way to solve this problem.

Because plastic is inferior to metal in terms of strength and stiffness, processing plastic threads by manufacturing metal threads must fail to meet the requirements. The threads of the outer ring of the plastic thread will have the risk of cracking or deformation. To avoid this problem, a step with a depth of 0.2-0.8MM should be set at the beginning of the thread; In addition, the end of the thread should be about 0.2MM away from the bottom.

Similarly, the starting end should also maintain a clearance of more than 0.2MM from the top surface, and the starting end and end of the external thread should not suddenly start and end, and excessive parts should be left. In addition, the injection molding manufacturer should pay attention to the size of the thread itself. Its diameter should not be too small, and the fitting length should not be too long, otherwise, the strength of the threaded connection will be reduced.

Eight common injection mold structure classification One. Single parting surface injection mold When the mold is opened, the movable mold and the fixed mold are separated, so as to take out the plastic parts, which is called single parting surface mold, also called double-plate mold. It is the simplest and most basic form of injection mold, which can be designed as single-cavity injection mold or multi-cavity injection mold according to the need, and is the

The difference between injection moulds and plastic moulds Many people can’t tell the difference between injection molds and plastic molds, and many people even think that they are the same kind of molds, just called different. Although injection molds and plastic molds are both molds, but there is a difference between them. Want to figure out the difference between the two, first and Xiaobian together to understand what is injection mold, what is plastic mold.
