Product category: Extrusion

Silicone extrusion

What is extrusion ?

Silicone extrusion consists in feeding the extruder with raw silicone materials, which will then be carried through a screw to the die* fixed on the extruder head in order to take the designed shape, and will follow its course on a heated treadmill to be cured and therefore fix its shape. Standard or specified tolerances are always defined as silicone rubbers, solid or sponge, will swell or shrink during transformation and post curing.

* The extrusion die is a tool shaped from steel, realized according to a sketch and adjusted before processing.

Sterne silicone extrusion workshop

We have 7 extrusion lines: 5 complete lines in our industrial workshop, screw diameter from 40 to 90mm, 1 complete line in our ISO 8 cleanroom and 1complete line in our ISO 6 cleanroom.
All these workshops are equipped with external mixers and ovens to make customized silicone blends and to post cure the articles.

Our silicone
Sterne offers a broad range of solid silicone materials (Silicone elastomer, Fluoro-Silicone, Peroxyde cured, platinum cured, etc... And sponge silicone (Industrial or FDA) with skin sides giving a smooth finish.

Product category: Injection molding

Silicone rubber molding

Silicone molding : by compression or Injection

Sterne is constantly integrating new technologies and enlarging its facility capacities to meet ongoing changing needs. Today, we are able to transform both liquid silicone rubbers (LSR) and high consistency silicone rubbers (HCR) combined with appropriate additives, to propose the most innovative silicone products, manufactured in either industrial or protected environment.

Customised design to meet precise requirements; we offer our services from prototyping, to small or very large series (automated production).

A great choice of materials:

  • Silicone rubbers (HCR & LSR)
  • Fluoro-silicones
  • Fluoro-Elastomers
  • Rubbers & polymers
  • TPE (Thermo Plastics Elastomers)
  • Thermo plastics
  • Other Elastomers
Our modern production facility allow us to process an extended selection of silicone rubbers :
hardness From 1 to 100 Shore A, unlimited colors, and a wide range of additives to meet most intricate needs: topmost temperature, low smoke toxicity and flame retardant, food standards, improved mechanical properties etc...

Our know-how, molding expertise and quality accuracy, allow us to propose standard tolerances according to the ISO 3302-1 Cat. M2 norm but we also can meet Cat. M1 or even tighter when necessary.

Sterne most advanced molding machines include:
  • Silicone compression molding machines from 10 to 400 tons
  • Silicone injection molding machines (HCR & LSR)
  • Rubber injection molding machines, Plastics & TPE injection molding machines
  • Automates

Inflatable seals

Inflatable seal : A concept

Inflatable sealing technology is the solution whenever there is a need to fill in a gap between two dynamic elements which need to be consecutively easily connected and disconnected. The pneumatic seal will expand and retract as wished.

Silicone inflatable seals can be used in many industries as they comply with topmost temperatures, pressures and with some fluids while answering specific standards & norms.

Silicone inflatable seal : A design

  • Hollow silicone profile with axial or radial expansion, stretched out of shape by bringing pressure in (air, gas, fluid). Most inflatable profiles and seals are often customized according to specific drawings based on the particularity of each application.
  • The profile is then vulcanized into either ring, frame, or straight length sealed at both ends, pressure is brought in by using a valve, either in metal or in silicone elastomer. The valve can be assembled either mechanically, simply glued, or over-molded with a cone on the profile. These custom-engineered inflatable seals are a real advanced solution for multiple applications.

Molded items

Custom silicone molded parts : a mastered technique

Sterne molding capabilities include compression and injection molding techniques. Custom silicone rubber parts are made in either High Consistency silicone Rubber or Liquid Silicone Rubber. Simple or complex silicone parts are manufactured using a multitude of technologies using our compression or injection molding machines. Our technical team will determine the right process and design the right mold according to the technical specificities (size, quantity, target cost, expected performances and tolerances, ...)

Standard tolerances respect ISO 3302-1 norm category M2, but tighter tolerances are also possible.

A large choice of silicone compound is available.
Sterne can produce prototype, unique piece, small, medium or mass series thanks to its host of machines.
Our R&D team offers technical assistance form the early stage of your silicone project to the design & final conception of the products.
