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

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:

We often see all kinds of patterns and Numbers on plastic pieces, and these Numbers are different. How to carve these Numbers and patterns on these molds, we have these kinds of common methods. The first is directly through the engraving machine engraved on the mold. This is usually used when the font or pattern

Many customers need injection molding after a product is newly designed. When a new product needs tool making, what information should the customer provide to the manufacturer? JasonMould shares you a general idea of what is required for tool making and injection molding. 3D CAD file of product. Bill of material ( including materials required

The main reasons for insufficient filling are as follows: 1) insufficient resin capacity. 2) insufficient pressure in the cavity. 3) resin fluidity is insufficient. 4) poor exhaust effect. As an improvement measure, we can start from the following aspects: 1) lengthen the injection time to prevent the resin countercurrent before the gate solidification due to
