Custom Solutions for Different Needs in Silicone Overmolding

We offer customized solutions to meet your specific requirements.

Our capabilities include:

Dimensional Tolerances: Achieving tolerances of 0.1-0.5 mm with precise molds and tooling, allowing for tight fits and reliable performance.
Material Properties: Our silicones have been extensively tested and documented, ensuring consistent quality across all materials. Providing silicone compounds that are resistant to environmental factors such as water, chemicals, and UV radiation, making them suitable for applications in harsh conditions like outdoor or industrial settings.
Complex Geometries: Designing molds for complex shapes and features like undercuts, cores, or inserts enabling you to create intricate parts with high precision.
Multi-cavity Molds: Producing multiple parts simultaneously with increased efficiency and reduced production time, allowing you to meet demanding production volumes without sacrificing quality or increasing costs.
Color Matching: Developing custom color combinations using Pantone colors, so that your products can be uniquely colored to match specific design requirements. Our silicone compounds can also be formulated with various colors or textures to add an extra layer of customization.

Silicone Overmolding Process: From Requirements to Mass Production

1. Requirements Gathering

Engage with the client. Review engineering aspects and suggest a solution. Move forward with approval.

2. Mold Design

Design a functional mold for both prototypes and mass production. Test for structural integrity and scalability.

3. CNC Mold Making

Use CNC machine to create precise metal molds. Prepare molds for prototype and mass production phases.

4. Prototype Silicone Overmolding

Overmold the prototype using the finalized mold.

5. Prototype Review

Compare the prototype against project specifications. Conduct iterative testing and adjustments. Opt for client review or in-house testing.

6. Transition to Mass Production

Start mass production after prototype approval. Use the finalized mold and process. Scale up production while ensuring quality and compliance.

Silicone Material Selection for Overmolding

Choosing the right silicone for overmolding tasks requires careful consideration, as it impacts the final product’s performance. The Platinum Extrusion Silicone series offers hardness levels from 40 to 80 A Shore. This lets you choose the right toughness for projects like LED co-extrusion, sleeves, neon strips, tubes, or shaped strips.

If you need clear, bubble free materials, think about the High Transparency Gas Phase Silicone series (Zy-8530 to Zy-8580). For bouncy items like seals, gaskets, or sports seat cushions, the High Rebound Gas-Phase Silicone (Zy-7830 to Zy-7880) is great.

Let us know what you need and we’ll assist you in choosing the right materials. You can also explore our silicones and their features on our website. We offer detailed information and test data for each type.
