CUSTOM SILICONE MANUFACTURING
Custom Silicone Extrusion
Precision Profiles, Tubing & Seals for Medical & Industrial Applications
WICSilicone delivers end-to-end silicone extrusion solutions, from design for manufacturability (DFM) and prototyping to production, post-curing, and spooling. We optimize compound selection, tooling, and process parameters to achieve application-specific tolerances, consistent profiles, and reliable performance across demanding operating environments.
From medical and food-contact applications to high-performance industrial systems, we work with manufacturers to develop custom-extruded silicone components tailored to their technical specifications, material requirements, and quality standards.
Key Properties and Performance
Thermal & Aging Resistance
Designed for demanding temperature conditions, with resistance to thermal aging and environmental exposure selected to suit the application.
Mechanical Performance
Compound options with tailored tensile strength, tear resistance, flexibility, and elastic recovery to meet component and operating requirements.
Weather & Environmental Resistance
Suitable formulations can provide resistance to UV exposure, ozone, and outdoor aging for profiles, seals, and components used in exposed environments.
Electrical Insulation
Electrical-grade silicone compounds can offer insulating performance for cable protection, sealing, and components exposed to demanding operating conditions.
Medical & Healthcare Applications
Selected silicone grades are available for medical tubing and components, with material selection guided by biocompatibility, sterilization, and applicable regulatory requirements.
Food-Contact Applications
Food-contact silicone grades can be selected for tubing, seals, and profiles according to the intended use and applicable food-contact requirements.
Available properties depend on compound formulation, extrusion design, operating conditions, and applicable testing requirements.
Advanced Silicone Extrusion Capabilities
WICSilicone specializes in the continuous extrusion of high-performance silicone tubing, profiles, and custom cross-sections for automotive, industrial, medical, and construction applications. Through controlled processing, application-specific compound selection, and custom-engineered extrusion dies, we aim to achieve consistent dimensions, uniform geometry, smooth surface finishes, and reliable component performance.
Our extrusion capabilities incorporate multi-zone temperature control and carefully managed process parameters to support repeatable production from prototype development to full-scale manufacturing. Compound selection, die design, and process settings are tailored to the profile geometry, dimensional requirements, and operating conditions of each application.
Extrusion Process Overview
Our silicone extrusion process integrates material selection, custom die design, controlled extrusion, curing, and quality inspection to produce profiles and tubing tailored to application requirements. Each stage is managed to support consistent geometry, suitable material performance, and dependable production quality for automotive, electrical, medical, and specialized industrial applications.
Material Options
We start with in-house silicone compound formulation, tailored for each application—whether requiring flame resistance, dielectric strength, UV/ozone durability, or FDA-grade purity. These compounds are processed through temperature-controlled extrusion lines with precise dosing and curing systems, ensuring uniform quality throughout the production run.
