Take a simple way to understand the injection molding process.
What is Injection Molding: The injection molding process is a process of making semi-finished parts of a certain shape from molten raw materials through operations such as pressurization, injection, cooling, mold opening, and mold release. Its raw materials are ABS\PE polyethylene, PP polypropyl...Read more -
How to do if there are shrinkage marks on the surface of injection molded products
1. Uneven wall thickness of the product causes uneven surface shrinkage, resulting in shrinkage marks. 2. Causes and solutions 1. Improper control of molding conditions. Appropriately increase the injection pressure and injection speed, increase the compression density of the solution, extend th...Read more -
Performance difference between PETG and PMMA
PETG and PMMA are both highly transparent materials, and relatively, the market is more familiar with PMMA. However, PETG’s real entry into the market began with transparent plastic packaging for high-end cosmetics. Before PETG was launched, PMMA was almost all used for transparent plastic...Read more -
Mold material selection
Mold material selection is a very important link in the whole mold making process. Mold material selection needs to meet three principles, namely: the mold meets the requirements of working conditions such as wear resistance, strength and toughness; the mold meets the process performance require...Read more -
Difference between 3D printing and CNC

First of all, you should know that 3D printing is a ki...Read more -
Plastic shrinkage is the problem of plastic shrinkage
1. There are four kinds of plastic shrinkage: thermal shrinkage, phase change shrinkage, orientation shrinkage, compression shrinkage and elastic recovery. The shrinkage process consists of three parts: shrinkage before solidification of gate, cooling shrinkage and shrinkage after demoulding. 2. ...Read more -
Description and application of product coating
There are different names depending on the type of paint used, for example, the primer coat is called the primer coat, and the finish coat is called the finish coat. Generally, the coating obtained by coating is relatively thin, about 20~50 microns, and the thick paste coating can obtain a coati...Read more -
