Industrial-grade vacuum casting service for 10–200 polyurethane prototype and low-volume parts

Industrial-Grade Vacuum Casting Services

Produce 10–200 polyurethane parts from silicone molds without investing in production tooling. Vacuum casting is ideal for appearance models, functional testing, pilot runs, and market validation when you need injection-molded-like results quickly.

Ideal for:

Low-volume runs of 10–200 parts with shorter lead times
Injection-molded-like appearance for design and assembly validation
Clear, tough, or heat-resistant polyurethane material options

Vacuum Casting Capabilities

From master pattern production and silicone mold making to resin casting and finishing, we support clear, tough, and heat-resistant polyurethane parts for prototypes, pilot runs, market testing, and low-volume replacement parts.

Vacuum casting master pattern produced by 3D printing or CNC machining for silicone mold making

Master Pattern

Features: Defines final surface quality and dimensional accuracy

Method: SLA 3D printing / CNC machining

Key consideration: Surface finish and parting strategy

Applicable scenarios:

Appearance models
Structural assembly verification
Low-volume production preparation
Silicone mold production and parting design, supporting complex structures and multi-cavity pouring

Silicone Mold Making

Features: Fast, lower-cost tooling for low-volume parts

Capabilities: Parting line, vent, and gate design

Key consideration: Mold life and batch consistency

Applicable scenarios:

Small batches of 10–200 pieces
Complex-shaped parts
Trial production and spare parts
Polyurethane vacuum casting with clear, tough, and heat-resistant material options

Polyurethane Vacuum Casting

Features: Injection-molded-like parts without production tooling

Materials: Standard / Clear / Tough / Heat-Resistant

Key consideration: Bubble control, shrinkage, and consistency

Applicable scenarios:

Cosmetic parts
Functional validation parts
Assembly test

Vacuum Casting Materials

Choose polyurethane resins that simulate acrylic, polycarbonate, ABS, nylon, acetal, or polypropylene, plus silicone and rubber-like elastomers. Options vary in clarity, gloss, toughness, impact and heat resistance, wear, chemical resistance, and flexibility.

Our engineers match the resin and finishing process to your appearance, assembly load, operating environment, life target, and budget. Because cast resins do not fully reproduce the long-term properties of production thermoplastics, we also review high-stress features and material limits before production.

Acrylic (PMMA)
Polycarbonate (PC)
ABS
Nylon (PA)
Acetal (POM)
Polypropylene (PP)
Silicone Rubber
Soft Rubber
Acrylic (PMMA)

Acrylic (PMMA)

Acrylic-like polyurethane provides clear, high-gloss parts for visual and appearance evaluation.

Applications: Transparent windows, light guides, instrument panels, display models, and cosmetic prototypes.

Why Choose XFabro for Vacuum Casting

Engineering review, resin selection, silicone tooling, casting, and finishing support for 10–200 appearance or functional parts.

  1. Automated 2D/3D File Analysis

    We analyze STEP, IGES, STL, DWG, and DXF files to identify dimensions, thin walls, holes, and assembly features for master pattern planning, mold design, and quoting.

  2. Design for Manufacturability (DFM) Review

    Engineers review parting and demolding, gates, vents, thin walls, long flow paths, shrinkage, deformation, bubbles, and surface-defect risks before production.

  3. Material and Finishing Options

    Compare standard, tough, clear, and heat-resistant polyurethane options with suitable appearance grades, finishing combinations, lead times, and costs.

  4. Engineering and Appearance Quality Control

    Engineers review the master pattern and parting plan, then control casting parameters, bubbles, voids, surface defects, and batch consistency against project requirements.

  5. Injection-Molded-Like Appearance

    Silicone molds reproduce surface texture and structural details, while painting, sandblasting, screen printing, or dyeing prepares parts for review and low-volume use.

Vacuum Casting Service Process

  1. Upload Your Design

    • Supported files: STEP, IGES, STL, DWG, DXF, and PDF
    • Include color, texture, transparency, quantity, and intended use when available
    • Initial file analysis: 1–5 minutes after upload

  2. Engineering Review and Quote

    • Review parting, demolding, gates, vents, thin walls, and bubble risks
    • Recommend standard, tough, clear, or heat-resistant resin and finishing
    • Standard-part quotes: 30–120 minutes

  3. Master Pattern Production

    • Select SLA or CNC machining based on appearance and accuracy requirements
    • Polish or texture the master pattern when required
    • Typical time: 1–3 days, depending on size and complexity

  4. Silicone Mold Making and Casting

    • Produce the silicone mold, vacuum-degas the resin, and cast the parts
    • Support clear, tough, heat-resistant resins and positioned inserts
    • Typical time: 2–7 days, depending on quantity and finishing

  5. Finishing, Inspection, and Delivery

    • Trim, finish, inspect, and prepare parts for shipment
    • Available finishes include sandblasting, painting, screen printing, and dyeing
    • Shipping: Domestic 1–7 days; international timing depends on destination
