Custom Molded Silicone Gasket Capabilities

While simple sheet stock is often die-cut, Temco Rubber specializes in custom molded silicone gaskets. Molding delivers significant engineering advantages for complex 3D geometries and dynamic contact pressure.

Complex 3D Profiles

Engineered to fit non-planar surfaces with integrated molded-in ribs that concentrate localized contact pressure for superior leak protection.

Variable Durometer

Formulated across a broad hardness spectrum from 20 to 80 Shore A to optimize compressibility and structural elasticity.

Overmolding & Bonding

Direct bonding of silicone onto metal or rigid plastic carriers, creating permanent leak-proof assemblies that streamline assembly.

Precision Tolerances

Molded tooling eliminates edge cupping and distortion common in die-cutting, ensuring absolute dimensional stability.

Specialized Silicone Rubber Material Grades

We categorize our silicone gasketing materials into specialized grades to meet strict functional, environmental, and regulatory standards.

Industrial Silicone Gaskets

Formulated to withstand extreme thermal fluctuations (-60°C to +230°C+). Essential for outdoor NEMA/IP-rated electrical enclosures, automotive under-hood components, and aerospace applications resistant to UV, ozone, and weather aging.

Food Grade Silicone Gaskets (FDA Compliant)

Manufactured using FDA-compliant polymers that are odorless, tasteless, and non-toxic. Highly resistant to CIP (Clean-In-Place) chemicals and repeated steam sterilization in food, beverage, and dairy processing.

Medical & Cleanroom Silicone Gaskets

High-purity, platinum-cured silicone formulations free from peroxide by-products. Delivers superior optical clarity and ultra-low extractables for life sciences, medical device housings, and pharmaceutical equipment.

Frequently Asked Questions

Technical answers directly grounded in our silicone gasket manufacturing capabilities.

What is the advantage of custom molded silicone gaskets over die-cut sheet gaskets? +

While die-cut gaskets are often cheaper for simple, flat shapes, custom molded silicone gaskets offer several technical advantages. Molding allows for the creation of 3D features like sealing ribs, which concentrate contact pressure and allow for lower bolt torque. Additionally, molding eliminates material waste associated with cutting centers out of sheets and provides a finished edge that is more resistant to tearing and environmental ingress. For high-pressure or high-vacuum applications, a molded gasket is almost always superior.

Can you manufacture silicone gaskets with complex 3D profiles and molded ribs? +

Yes. As a specialized silicone rubber gasket manufacturer, we frequently produce gaskets with complex cross-sections. This includes D-profiles, P-profiles, and custom-engineered geometries designed to fit into specific machined grooves. Molded-in ribs provide multiple points of contact (redundant sealing) and compensate for minor irregularities in mating hardware surfaces.

What information is required to get an accurate quote for custom silicone gaskets? +

To provide an accurate and competitive quote, we typically require a 2D technical drawing or a 3D CAD file (STEP or IGES format). Key information includes the desired material grade (e.g., food grade silicone gasket vs. high-temp industrial), the required durometer (hardness), estimated annual volume, and any specific regulatory requirements (FDA, UL 94 flame rating, etc.). If you are unsure of material specs, our engineers can assist based on operating temperature and chemical exposure.
