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…
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:…
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…
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…
Ultrasonic welding in the assembly of plastic parts is commonly used to a process. ABS, PC+ABS, PP, PC, etc. these materials are suitable for ultrasonic welding. Generally used for ultrasonic two parts are required to be the same material. Ultrasonic bonding will be better. If nylon or POM is used to ultrasonic with ABS, this…
