Vacuum Casting Service

High-Precision Plastic Prototypes & Low-Volume Production

Vacuum casting is a fast, accurate, and cost-effective method for producing high-quality plastic parts that closely match injection-molded components. Using silicone molds, we deliver rapid prototypes, functional parts, and low-volume batches with excellent finish and consistency.

Whether you need a single part or a few thousand, our engineering team ensures tight tolerances, material accuracy, and smooth surface finishes—perfect for end-use applications. We guarantee superior quality, quick turnaround, and optimized costs from prototype to production.

Why Choose Vacuum Casting?

Benefits Details
Cost-Effective Cheaper than CNC or injection molding for small volumes
Fast Turnaround Mold & parts delivered within days
Excellent Surface Finish Smooth, textured, or color-matched
Repeatability Consistent quality over multiple batches
Simulates Final Product Mimics real injection-molding materials
Functional Testing Flexible, clear, rigid, and impact-resistant options

Material Options (Polyurethane Resins)

Material Type Property Suggested Applications
ABS Strong, rigid Housings, electronics, general prototypes
PC (Polycarbonate) Heat resistant, high impact strength Protective covers, transparent parts
Rubber-like Flexible (Shore A 30–95) Seals, grips, shock absorbers

Design Guidelines for Vacuum Casting

Parameter Recommendation
Minimum Wall Thickness ≥ 1.0 – 1.5 mm
Maximum Wall Thickness ≤ 6 mm for uniformity
Draft Angle 0° needed for most cases
Undercuts Supported using mold inserts
Surface Textures Standard, matte, glossy, sandblast
Tip Uniform wall thickness improves part strength and visual quality.
