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…
Now the plastic mold industry has higher and higher requirements for machine equipment and testing instruments! The price of CMM and other testing equipment is also increasing, which shows that the improvement of quality is the future development direction of the whole plastic mold industry. After more than 10 years of continuous exploration and learning,…
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…
Product structure is undoubtedly the key factor to determine the price of the mold, the realization of a product function has a variety of different design, different design determines the mold manufacturing method is not the same, determine the price of the mold will be different, some structure only need us to pay attention to…
What is PC + ABS material? PC plastic is a new type of thermoplastic with 90% transparency, so it is called transparent metal. It is very hard, with high impact strength and high dimensional stability, as well as a wide range of application temperature, good electrical insulation, heat resistance and non-toxic properties ABS is a…
