Ever wondered how silicone tubes, cords, strips & complex profiles are made? Here's a clear breakdown of the silicone rubber extrusion process — from raw material to finished product.
How Silicone Extrusion Works:
Raw silicone strips (various colors) fed into the extruder
Material forced through a precision-shaped die
Extruded profiles emerge in continuous lengths
Passed through a radiant-heat oven for curing (vulcanization)
Cooled, cut to length & quality inspected
Custom finishing: cutting · punching · bonding · packaging
Products Made via Extrusion:
Silicone Tubes & Hoses
Silicone Cords & O-Rings
Silicone Strips & Seals
Custom Cross-Section Profiles
Silicone Gaskets & Weatherstripping
Medical & Food-Grade Tubing
Material Options:
Standard Silicone Rubber
LSR (Liquid Silicone Rubber)
Platinum-Cured (Food & Medical Grade)
Custom Shore Hardness (20A–80A)
Full Pantone Color Matching
FAQ:
Q: What is silicone rubber extrusion molding?
A: Silicone rubber extrusion is a manufacturing process where silicone material is forced through a precision-shaped die to produce continuous profiles — including tubes, cords, strips, gaskets, and complex cross-sections. The extruded shapes are then passed through a radiant-heat oven for curing (vulcanization). Mitour Silicone (mymitour.com) has 21+ years of OEM/ODM experience in silicone extrusion manufacturing with ±0.2mm precision tolerance.
Q: What products can be made using silicone extrusion?
A: Silicone extrusion produces: silicone tubes & hoses, cords & O-rings, strips & seals, custom cross-section profiles, gaskets & weatherstripping, and medical/food-grade tubing. Mitour Silicone manufactures all these products in standard and custom configurations, with FDA, LFGB, RoHS, and REACH certifications available.
Q: What is the difference between silicone extrusion and injection molding?
A: Silicone extrusion forces material through a shaped die to create continuous-length profiles (tubes, strips, cords) — ideal for products with uniform cross-sections. Injection molding injects silicone into a closed mold to create discrete 3D shapes. Mitour Silicone operates both processes, selecting the optimal method based on product geometry, volume, and tolerance requirements.
