No matter what kind of mold is inseparable from the components, plastic injection mold is the same. Here Jasonmould shares you the basic parts of the plastic injection mold. Forming parts, including the die, punch, a variety of forming core, are forming products inside, outside the surface or upper, lower end, side hole, side concave

The surface of the plastic part can be sprayed to ensure the brightness of the product. Because plastic is so hard to embody, plastic parts look darker, and even darker if they are covered in leather. Therefore, in the pursuit of a beautiful surface, Some customers requires to spray a layer of  painting on the

The cavities in Plastic injection mold is not the more the better, also not all molds can be done with 4 cavities or 8 cavities. So what are the factors affecting the numbers? Let’s have a look below: Relationship between the product size and equipment. When the part belongs to large or medium size, generally

Today, we would like to introduce the forming characteristics of ABS in plastic injection molding. 1.ABS is easy to absorb water, and should be dried before forming. Plastic parts with high surface gloss requirements should be preheated and dried for a long time Medium liquidity, about 0.04mm overflow edge. The wall thickness and melting temperature

As we all know, the stripe defect in mold is a very serious matter, it will directly affect the accuracy of injection molding, and will also lead to product scrap, so we must pay attention to. So, how can we avoid this defect? Proper design, careful processing, reasonable mold repair and timely nitriding are the

The design of the injection mold was not fully collectively reviewed, and the structure of the injection mold was unreasonable, which caused the injection mold to undergo multiple improvements after the test, which made the injection mold cost exceed the budget. If it can be solved after several improvements, it is relatively fortunate. There are

In order to ensure the normal processing of plastic parts, operators need to understand the cause of the abnormal appearance in this process, the better to avoid the abnormal appearance during processing. Below, JasonMould share you the causes of deformation in processing: During the process of molding, the surplus material is spilled into the gap

The basic reason for surface sag: from the perspective of plastics, when the plastic cools and shrink, insufficient filling will lead to product surface sag or internal cavity. The causes and solutions of defects are different depending on the location of sag. When the sag occurs at the final cooling position of the thick-walled product,

Some plastic parts after demoulding, have swelling or bubbling on the back of metal insert or in the extra thick parts. This is due to the expansion of the released gas under the action of internal pressure on the plastic which has not been completely cooled and hardened. JasonMould works with you for details.
