Vacuum Casting/ Silicone Molds

Silicone Mold Manufacturing

Vacuum Casting

This type of manufacturing offers a more feasible cost and lower MOQ compared to injection molding. Offering high quality finish with excellent surface details for end-product usage. Material options are also available like ABS, PA, PC, PP and POM which are engineering grade materials. Vacuum casting is also a viable process for prototyping or market testing before going to actual mass production with injection molding. Dimensional accuracy is at 0.25mm tolerance.

Why Choose Vacuum Casting

Lower Cost & MOQ: Silicone tooling is fast to build and far less expensive than steel or aluminum molds, enabling economical batches from 1–300+ parts.

High-Quality Finish: The flexible mold captures fine textures and details, resulting in smooth surfaces suitable for end-use components.

Speed: Typical lead time is faster than injection molding making it ideal for tight schedules, pilot runs, and market testing.

Design Agility: Iterations are easy and cost effective making it friendly for revision runs before final product manufacturing.

Material Options

Polyurethane (PU) resins can emulate common engineering thermoplastics:

ABS-like: Balanced toughness and machinability for housings and brackets.

PA (Nylon)-like: Improved wear resistance and toughness for functional parts.

PC-like: High clarity and impact resistance for lenses or guards.

PP-like: Good fatigue resistance and flexibility for living hinges and clips.

POM/Delrin-like: Low friction and dimensional stability for moving components.

PMMA and PC Transparent: PX521HT and PX5210 material for transparent material requirements

TPU-like: Shore hardness range of A10-90 depending on desired specification.

Typical Use Cases

  • Pre-production prototypes and engineering validation
  • Short-run end-use parts for low-volume products
  • Marketing samples and end-user testing
  • Bridge manufacturing before injection molding
