PBT Plastic Parts Manufacturer

In the PBT Injection Molding Service industry, although many manufacturers have fixed customers on hand, they are still actively expanding sales channels and seeking more cooperation opportunities. Some small injection molding factories often visit large factories in the hope of obtaining outsourcing processing orders. However, the premise of whether cooperation can be achieved is whether their own processing technology is up to standard, because injection molding manufacturers attach great importance to processing quality.

The quality of injection molding is affected by many factors, and different production materials require different processing technologies and precautions. Today, we will take PBT materials as an example to explore some key issues in injection molding.

First of all, the injection molding machine is an indispensable equipment for injection molding, which directly affects the processing quality. When using PBT, the selected injection molding machine must meet production requirements. If the temperature of PBT in the injection molding machine material tube exceeds 280℃ and the residence time is too long, the material will decompose, thereby affecting the performance and quality of the product. Therefore, the appropriate injection volume should be selected, and the use of an injection molding machine with too large an injection volume should be avoided to prevent PBT from staying in the material tube for too long and causing decomposition.

When selecting an injection molding machine, you should also pay attention to the configuration of the screw and nozzle. It is recommended to choose a small diameter screw to reduce the wear of parts. At the same time, you can consider using a screw plated with hard chrome to improve durability.

When using PBT, you also need to pay attention to its melting point and viscosity. In the product design stage, the thickness should be balanced to ensure that the product streamlines smoothly and avoid sharp angles and notches. PBT has good fluidity and is easy to fill the mold, so the force should be controlled during injection to avoid excessive force, so as not to affect the molding effect.

In addition, demolding and pouring also have their own precautions. Injection molding manufacturers should constantly summarize their experience during the production process to improve their own processing level and product quality.
