Silicone Extrusion Molding

Q: Q: What’s the difference between silicone extrusion and injection molding?

A: Silicone extrusion is ideal for continuous, linear products with a consistent cross-section (e.g., tubes, strips) and high-volume production, with lower tooling costs. Injection molding is better for complex 3D shapes (e.g., custom buttons, intricate seals) but has higher mold costs and lower production efficiency for bulk linear products.

Q: Q: What is the minimum order quantity (MOQ) for custom extrusion?

A: Our MOQ is flexible: We support small-batch trials for you to test product performance before bulk orders.

Q: Q: How long does it take to produce custom silicone extrusion products?

A: For standard orders (using existing dies): 7-15 days. For custom dies + production: 15-35 days (die design & production takes 7-15 days). We prioritize fast turnaround to meet your production deadlines.

Q: Q: Can you provide samples before bulk production?

A: Yes! We offer samples for standard profiles. For custom profiles, we charge a small sample fee (refundable upon bulk order). Samples are ready in 3-5 days.

Q: Q: Do you provide custom die design for unique profiles?

A: Yes. Our in-house engineering team can customize molds based on your 2D/3D drawings or sample requirements to ensure the profiles have the perfect shape and precise dimensions. Our mold costs are highly competitive, and we offer mold storage services for your future orders.

Q: Q: Can you produce silicone profiles with specific colors or transparency?

A: Yes, we can match any Pantone color or produce clear/translucent silicone profiles.

Q: Q: How do I determine the right silicone compound for my application?

A: Our engineering team will work with you to select the optimal material based on your temperature, chemical, and performance requirements.

Q: Q: Do you provide post-processing services?

A: Yes, we offer cutting-to-length, bonding, assembly, and surface treatment services.

Silicone Extrusion Molding Process

Material Preparation

Mixing raw silicone with additives for specific properties (hardness, temperature resistance, color).

Extrusion

Feeding compounded silicone through a precision-engineered die to form the desired shape.

Curing

Heating the extruded profile in a continuous vulcanization oven (CV) or salt bath.

Post-Processing

Cutting to length, secondary operations (bonding, assembly, surface treatment).

Quality Inspection

Dimensional verification, material testing, and performance validation.

What is Silicone Extrusion Molding?

Silicone extrusion molding is a continuous process where uncured silicone rubber is forced through a precision die under controlled pressure, then vulcanized in a heated air channel or LTM (Liquid Thermal Medium) system.

This method enables the production of uniform, high-tolerance profiles with consistent cross-sections, ideal for sealing, insulating, and protective applications.

Application Fields

Industries We Serve with Silicone Extrusion:

Aerospace: Seals, gaskets, and insulation for aircraft and spacecraft.
Automotive: Door seals, window trims, and engine components.
Medical Devices: Catheters, tubing, and surgical instrument components.
Consumer Electronics: Gaskets for smartphones, wearables, and home appliances.
Industrial Equipment: Seals, gaskets, and conveyor belt components.
Construction: Weatherstripping, window seals, and building insulation.
