Product Description

Micro injection molding is a highly specialized plastic manufacturing process designed for ultra-small and ultra-precise components, typically in the milligram weight range. It enables the production of extremely fine structures that traditional injection molding cannot achieve.

This technology is widely used in industries requiring miniaturization, high precision, and complex micro-scale geometries, such as medical devices, electronics, and precision engineering.

Key Features

Manufacturing Process

  1. Micro-scale mold is designed with ultra-high precision
  2. Specialized micro-dosing system prepares material
  3. High-speed injection fills micro cavities instantly
  4. Rapid cooling ensures dimensional stability
  5. Automated ejection under microscopic tolerance control
  6. Strict inspection under precision measurement systems

This process requires extremely precise control of pressure, temperature, and injection timing.

Suitable Materials

Micro injection molding supports high-performance engineering polymers:

Material selection depends on flowability, stability, and micro-forming capability.
