Frequently Asked Questions

Plastic injection molding is a manufacturing process used to produce plastic parts by injecting molten plastic material into a precisely engineered mold. This method enables high accuracy, consistent quality, and efficient mass production for complex and tight-tolerance components.

The purpose of injection molding is to manufacture plastic parts efficiently, consistently, and at scale. It is widely used to produce high-quality components with complex geometries, excellent surface finish, and stable dimensional accuracy for industrial and OEM applications.

The injection molding process generally consists of four main steps:

Clamping: The mold is securely closed and held under pressure.
Injection: Molten plastic is injected into the mold cavity.
Cooling: The material cools and solidifies into the desired shape.
Ejection: The finished part is released from the mold.

Minimum order quantity (MOQ) depends on the part design, material selection, and tooling requirements. At Banshu Plastic, we support both low-volume production for new projects and mass production for established OEM programs, with flexible discussion based on customer needs.

Injection molding uses a wide range of plastic materials, with a strong focus on engineering plastics for industrial and OEM applications. At Banshu Plastic, we predominantly process materials such as PC, Nylon (PA), POM, reinforced resins, and flame-retardant grades that offer superior strength, heat resistance, dimensional stability, and electrical safety. Material selection is tailored to meet specific mechanical, thermal, and regulatory requirements of each application.
