    What is Silicone Molding?

    The silicone molding process enables the production of tough yet flexible and temperature-resistant silicone elastomer components. The manufacturing sequence starts by injecting or compressing silicone liquid or solid material into a mold cavity until curing completes to create the endorsed final form.

    Silicone molding remains a prominent manufacturing technique because it offers distinct properties which include:

    Silicone exhibits remarkable heat resistance by maintaining its flexibility when exposed to extreme temperatures.

    • Durability –High wear resistance for long-lasting performance.
    • Biocompatibility – Ideal for medical and food-grade applications.
    • Resistance –This material demonstrates resistance against chemical agents to provide UV protection and oil immunity.
    • Flexibility & Softness –This material provides flexibility and softness that makes it ideal for soft applications.

    Our high-precision method allows each silicone-molded product to fulfill precise dimensional standards while maintaining exact material quality benchmarks.

    Our Silicone Molding Services

    So, the following are our silicone molding services;

    1. Liquid Silicone Rubber (LSR) Molding

    The advanced injection molding process, LSR, uses a state-of-the-art production technique for accurate complex silicone part manufacturing. This proves best-suited to make applications that require both high flexibility with biocompatibility and extended durability.

    Applications:

    • This service requires silicone medical devices ( pořádage devices, tubes, gaskets, and implants).
    • Automotive Components (Gaskets, O-rings, electrical connectors)
    • Consumer Electronics (Keypads, buttons, seals)
    • Wearables & Smart Devices (Soft-touch components)

    Advantages:

    • High precision & repeatability
    • Fast-curing technology allows for quick production of high-volume products.
    • Resistant to extreme temperatures & chemicals
    • Biocompatible & FDA-approved options available

    2. Compression Molding

    The compression molding technique delivers affordable production costs for manufacturing runs from medium to lower volumes. During this process, manufacturers introduce silicone material that is waiting to cure into a heated mold under compression pressure to achieve the desired shape.

    Applications:

    • Gaskets & Seals
    • Industrial Silicone Parts
    • Automotive & Aerospace Components
    • Medical-Grade Silicone Parts

    Advantages:

    Tooling expenses during compression molding remain lower than when using injection molding methods.

    • Suitable for thick, large, and complex parts
    • High-strength and durable results
    • Ideal for custom silicone components

    3. Transfer Molding

    Transfer molding achieves enhanced dimensions while creating products with minimal leftover material compared to compression molding. The method produces complex silicone items that incorporate multiple elements.

    Applications:

    • Electronic Silicone Components
    • Custom Gaskets & Seals
    • Manufacturing facilities combine silicone material with other elements through overmolding strategies to create rubberized grips along with connectors.

    Advantages:

    • The production method provides superior accuracy than compression molding.
    • Silicone parts of small or detailed dimensions find this process suitable for production.
    • The production process enables the wrapping of silicone substances around both metallic and plastic-fixated materials.

    4. Overmolding & Insert Molding

    Our company specializes in the combination of silicone overmolding with insert molding to blend silicone with plastic or metal materials for superior durability along with improved functionality.

    Applications:

    • Medical Instruments (Surgical tools with soft grip controls)
    • Consumer Products (Features non-slip handles with soft-touch surfaces)
    • Electronics (Seals, waterproofing components)

    Advantages:

    • Silicone bonds very well to materials used for the base structure.
    • Through silicone overmolding product assembly becomes simpler while durability improves.
    • It increases product performance and user experience.

    Silicone Molding Design Guide

    Silicone molding design depends on a comprehensive evaluation of material properties, moldability, and functional specifications. The following table presents essential design guidelines for optimal performance and cost-effective manufacturing.

    Design Factor

    Recommendation

    Notes

    Wall Thickness

    0.5mm – 3mm

    Uniform thickness prevents warping and defects.

    Tolerance

    ±0.05mm – ±0.1mm

    Depends on mold type and material properties.

    Draft Angle

    0.5° – 2° per side

    Helps with easy part removal from the mold.

    Undercuts

    Avoid if possible

    Adds complexity and may require side actions.

    Radii & Fillets

    Min. 0.5mm fillets

    Reduces stress concentration and improves flow.

    Shrinkage Rate

    1% – 4%

    Varies based on material and curing process.

    Gates & Vents

    Small gates with adequate venting

    Ensures smooth material flow and reduces air traps.

    Overmolding Bond Strength

    Roughen substrate surface

    Enhances adhesion between silicone and other materials.

    Texturing & Finish

    Matte, glossy, or custom textures

    The surface finish affects aesthetics and functionality.
