The Basic Steps of TPU Injection Molding

TPU injection molding is a commonly used plastic molding process, mainly used to produce various TPU products. The following are the basic steps for TPU injection molding:

1. Preparation of raw materials: TPU particles are mixed in a certain proportion, and auxiliary materials such as fillers, toughening agents, dispersants, etc. are usually added.

2. Melting: Put the prepared TPU particles into the hopper of the injection molding machine, and melt them into a molten body through heating and stirring.

3. Injection: Injecting molten TPU into the mold cavity through the injection system of an injection molding machine, usually requires controlling parameters such as injection pressure, injection speed, and injection time. During the injection process, attention should be paid to selecting appropriate parameters such as screw length to diameter ratio, compression ratio, and nozzle diameter to ensure that the molten material can smoothly enter the mold cavity.

4. Cooling: Cool for a period of time in the mold to quickly cure the TPU material formed by injection molding. In this process, the design of the main flow channel and diversion channel is also very important. They should facilitate the demolding of flow channel debris and be symmetrically and equidistantly distributed.

The TPU injection molding process has many advantages, such as high production efficiency, good product quality, and good repeatability. In addition, TPU material itself has excellent elasticity, wear resistance, hydrolysis resistance, and weather resistance, and is therefore widely used in fields such as electronics, shoe materials, clothing, industrial components, and sports equipment.
