Pros:

  • Strong metal-plastic bond
  • Reduces assembly steps
  • Improved part reliability

Cons:

  • Higher mold complexity
  • Slower cycle time

Overmolding

Two-shot molding process that bonds a soft material (TPE/TPU) over a rigid substrate.

Pros:

  • Soft-touch ergonomic grip
  • Water/seal gasket integration
  • Multiple color options

Cons:

  • Higher tooling cost
  • Requires 2 molds

Clear / Transparent Molding

Precision molding of transparent parts using PMMA, PC, or optical-grade materials.

Pros:

  • Optical clarity
  • LED light guide capability
  • Scratch-resistant coating options

Cons:

  • Strict mold finish requirements
  • Flow marks possible

Threaded Inserts

Mold-in or ultrasonic insertion of threaded brass inserts for secure fastening.

Pros:

  • Strong threaded connection
  • Repeated assembly/disassembly
  • Standard screw sizes

Cons:

  • Added insert cost
  • Secondary operation needed

Surface Finish

VDI 3400

Standard mold texture finish, VDI #0 to #45

SPI Finish

Polished finish from A1 (mirror) to D3 (rough)

MT Texture

Japanese standard texture pattern for precise surface

Custom Texture

Logo, pattern, or grain texture as per your design

Secondary Operations

A wide range of secondary operations to decorate your parts after molding. We save you time and money in your production process.

Pad Printing

Transfer 2D graphics onto 3D surfaces using silicone pads.
