Compression Molding

Ideal for Converting Metal to Composite

Compression molding uses heat and pressure to shape a pre-measured material charge inside a heated mold cavity. It’s one of the most efficient ways to produce strong, lightweight composite parts with tight tolerances and excellent surface finishes.

Why Choose It?

  • Excellent for replacing metal (lighter, corrosion-resistant, strong)
  • Supports complex shapes and part consolidation
  • 50–2,000 tonnage press range
  • Great for medium-to-high volume production
  • Reduced waste and cycle times

Transfer Molding

Precision and Control for Complex Geometries

Transfer molding bridges the gap between compression and injection molding, combining material flow control with high cavity detail. It’s ideal for parts with embedded components or intricate internal structures.

Best For:

  • Mid-size production volumes
  • Precision parts with internal complexity
  • High repeatability and design flexibility

Injection Molding

High-Speed, High-Volume, High Accuracy

Injection molding involves injecting material into a closed mold under high pressure, allowing fast cycle times and excellent repeatability. Perfect for parts that demand detail, consistency, and scalability.

Strengths:

  • Supports tight tolerances and complex details
  • Highly automated for low-cost per part
  • Scalable from small to large volumes
  • Reliable for both thermoplastic and thermoset materials
