Micro injection molding components

What Is Micro Molding?

Micro molding is a specialized manufacturing technique for creating tiny, high-accuracy, and precise components, typically with a diameter under 4 millimeters or a weight less than 1 gram.

Micro injection molding is a specialized subset of plastic injection molding, tailored for the production of next-generation components that are extremely small yet require precise tolerances and intricate details. Many product developers are unaware that these miniature parts can often be manufactured more quickly and cost-effectively using smaller, dedicated machines.

Micro Manufacturing Capabilities

  • Less Invasive Devices: Utilizing extreme thin wall molding techniques, we achieve less invasive medical devices.
  • Precision at Micro Scale: High precision enables intricate micro functionalities, pushing forward medical technology within confined spaces.
  • True Miniaturization: Parts are now smaller than a pellet of resin, demonstrating true miniaturization.
  • High Aspect Ratio Molding: Successfully manage high aspect ratio flow lengths, ensuring complex part designs.
  • Mold Design Innovations: Molding with virtually no draft and tolerances so tight they were once unimaginable.
  • High Precision Assembly: Positional accuracy in assembly reaches +/- 1.5 microns, ensuring perfect alignment.
  • Surface Technology: Incorporating functional surface technologies like micro holes, microfluidics, true sharps, and micro barbs.
  • Complex Geometry Handling: Manufacturing parts up to 7″ (177.8mm) that maintain micro features, thin walls, and complex geometries with tight tolerances.
