  • Silicone Mold
    Corresponding Process: Vacuum Casting
    ● Core Material: Two-component Polyurethane (PU) Resins. This is the most common and primary material. These liquid resins are mixed under vacuum and poured into the silicone mold to cure.
    ● Material Properties & Simulation Capabilities:
    · Standard Grades: Can simulate the mechanical properties and appearance of common plastics like ABS, PP, PC, PA (Nylon), PMMA (Acrylic). Available in various hardness levels (from soft elastomers to rigid parts).
    · Transparent Grades: Transparent PU resins can produce high-clarity prototypes, simulating the appearance of PMMA, PC, or glass.
    · Specialty Grades: Include high-temperature resistant (can withstand over 120°C short-term), flame-retardant (up to UL94-V0 rating), and elastomeric grades (simulating rubber).
    ● Advantage: Very wide range of material simulations, colorable, capable of producing parts from soft to hard, transparent to opaque.
    ● Limitation: The long-term aging resistance, chemical resistance, and ultimate mechanical strength are typically inferior to true engineering plastics. Primarily used for validation, not for final long-term use.
  • Resin Molds
    Corresponding Process: Low-Pressure Injection Molding
    ● Core Material: Real thermoplastic pellets.
    ● Common Materials:
    · Commodity Plastics: ABS, PP, PE, PS.
    · Engineering Plastics: PA (Nylon), POM (Acetal), PC, PMMA, PET, PBT.
    · Some Performance Plastics: Such as glass-fiber reinforced nylon.
    ● Advantage: The produced parts are in the genuine, intended material, possessing real mechanical properties, chemical resistance, and thermal performance. This is its key value proposition.
    ● Limitation: Due to the mold's strength limits, injection pressure and temperature cannot be too high. Therefore, materials with good flow characteristics (typically higher Melt Flow Index) are preferred. Not suitable for high-temperature plastics (e.g., PPS, PEEK) or highly filled materials.
  • Aluminum Molds
    Corresponding Process: Standard Injection Molding
    ● Core Material: Virtually all commercial thermoplastic materials.
    ● Common Materials: Almost all materials compatible with production injection molds can be used, including:
    · All materials suitable for Resin Molds.
    · Materials with poorer flow or higher processing temperatures: e.g., PC/ABS blends, reinforced PP, high-temperature nylons.
    · Highly filled materials: e.g., glass-fiber or carbon-fiber reinforced composites with high filler content.
    ● Advantage: Offers the broadest material selection, producing parts identical in performance to final production parts. Allows for validation of real material shrinkage, weld lines, and other processing characteristics.
    ● Note: For plastics with strong corrosiveness (e.g., PVC) or extreme abrasiveness (e.g., some mineral-filled grades), the service life of aluminum molds will be significantly reduced. Material selection should be cautious, or surface treatments may be required.
