How to ensure that the mold processing orders can be completed successfully? Size Each customer if wants to choose, to ensure their own mould processing orders can be smoothly in a short period of time, it is best to also will be able to determine the size of each enterprise, that is to say as…
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 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,…
Discoloration refers to the inconsistency between the surface color of the formed parts and the required color. Discoloration may be caused by a variety of reasons, including injection molding machine, plastic mold, injection process and raw materials. (1) Injection molding machine ① The equipment is not clean and needs cleaning. Dust or powder deposited in…
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. Solutions:…
