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
