2K Moulding Design Guidelines

Optimize Your Design for Dual-Material Success

Successful 2K moulding requires careful consideration of material compatibility, part geometry, and processing parameters. Our design guidelines, developed through decades of experience, ensure optimal results for your dual-material applications.

Material Selection

Compatible Material Pairing

Choose materials with compatible processing temperatures and chemical bonding properties.

Key Tips:
  • Validate material compatibility through testing
  • Consider shrinkage differences between materials
  • Ensure processing temperature compatibility
  • Evaluate chemical bonding potential
  • Test long-term adhesion performance
Part Geometry

Optimal Geometry Design

Design parts to maximize bonding area and minimize stress concentrations.

Key Tips:
  • Maximize contact area between materials
  • Avoid sharp transitions between materials
  • Design for proper material flow
  • Consider differential shrinkage effects
  • Include mechanical interlocks where appropriate
Wall Thickness

Wall Thickness Considerations

Maintain appropriate wall thickness for both materials to ensure quality bonding.

Key Tips:
  • Keep first shot walls 1.5-4.0mm thick
  • Minimum 0.5mm thickness for second shot
  • Avoid thick sections that cause sink marks
  • Transition gradually between thicknesses
  • Consider cooling and cycle time implications
Bonding Areas

Bonding Surface Optimization

Design bonding surfaces to maximize molecular adhesion between materials.

Key Tips:
  • Create maximum surface area for bonding
  • Avoid contamination of bonding surfaces
  • Design for proper material encapsulation
  • Include undercuts for mechanical bonding
  • Consider surface texture for adhesion
