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. 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

Injection molding is a processing method used in mass production of complex parts. Specific principle refers to: heat melting plastic raw materials by injection molding machine screw into the mold cavity, after cooling and curing, plastic forming products. The plastic mold consists of two parts: moving mold and fixed mold. The moving mold is installed

In the process of mold manufacturing, deformation often occurs, so how to avoid the deformation in mold manufacturing? (1) the thickness of the product shall be as uniform as possible. (2) all parts of the cooling system are designed to make the cavity temperature uniform. (3) the pouring system can make the material flow symmetrical,

Defects in most injection molding products are caused during the plasticizing and injection phases of the injection molding parts, but are sometimes related to design irrationality, including the type of injection port, the number of mold cavities, location and size, the design of the cold and hot runner system, and the structure of the product
