When designing each injection molding product, we must first determine its mold opening direction and parting line to ensure that the core pulling slider mechanism is minimized and the influence of the parting line on the appearance is eliminated. 1. After the mold opening direction is determined, the product’s reinforcement ribs, buckles, protrusions and other […]

Plastic varieties: During the molding process of thermoplastics, there are volume changes caused by crystallization, strong internal stress, large residual stress frozen in the plastic parts, strong molecular orientation and other factors. Therefore, compared with thermosetting plastics, their shrinkage rate is larger, the shrinkage rate range is wider, and the directionality is obvious. In addition,

Black spots and impurities are important factors that cause scrap rates in normal production processes. They mainly affect the appearance of products and lead to product scrapping. Impurities and most black spots are foreign substances and have nothing to do with the raw materials themselves, while a small number of impurities and black spots are

1. Turn on the main power switch of the machine tool, check whether the equipment is leaking electricity, preheat the barrel and mold according to the set process temperature requirements, and keep the barrel temperature for more than 20 minutes when it reaches the process temperature to ensure that the temperature of all parts of

If the plastic part shrinks unevenly, it often causes uneven distribution of internal stress. If this stress exceeds the rigidity of the plastic part, it will cause warping and deformation of the plastic part, affecting the dimensional stability of the plastic part. 1, What is warping for injection mold parts? When internal stress (due to

Start mold closing clamping 1.Starting mold clamping pressure: The initial setting value is 25. When the pressure is too low and the speed is too slow, you can try to increase the speed. If the pressure is too low and the speed cannot be increased to the required level, try adding +5 each time. Note

Injection molding machine production is generally 24 hours a day. For machines that are in working condition for a long time, we must do a good job of maintenance and try to find and solve problems before the machine fails. Otherwise, once the machine fails, it must be stopped and repaired, affecting production. Therefore, it

Injection molding machine Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the
