Multi-component injection molding
starlim specializes in the manufacture of silicone parts in mass production and also offers multi-component injection molding (also called 2C injection molding). Provided that at least one of the required components is silicone, starlim combines this material in a reliable process.
The following component combination are possible:
- Silicone thermoplastic
- Silicone metal
- Silicone glass
- Silicone-silicone, e.g. in different Shore A hardnesses or colors
The two materials are combined with one another either through chemical or mechanical bonding. First, component 1 (thermoplastic, metal, glass, silicone) is injected or inserted into the tool, followed by the overmolding of the silicone in the second step.
Examples for well-known multi-component products are steering wheel switches for the car, spray generators for the shower head, the push button for the doorbell or the hydraulic brake system for kitchen drawers, doors and flaps.
Product Development
Product development
At starlim, we have extensive material and process knowledge about the phenomenon of silicone. With reference to your requirements, we start with the product development together.
Tool making
Tool making
We stick to the “single source supply” principle. Marchtrenk is not only the center for the development of products. Here we design and produce the molds for injection molding products exclusively in our own tool making department. Our expertise is concentrated entirely here at our HQ. This makes us independent and we can react in a flexible manner.
Rapid Tooling
Rapid Tooling
Early mass production-like LSR parts within only 10 working days – this is rapid tooling starlim-sterner-style.
Rapid Tooling – fast tool making – was developed so our customers could be offered first LSR injection parts after a brief time span; those parts were made under mass production-like conditions.
Test tool
Test tool
First serial parts within a short span of time. By producing a test tool it is possible to offer our customers LSR injection molding parts which after a brief time span were made under mass production conditions.
Micro injection molding
Micro injection molding
At starlim, components are manufactured in large series as standard, which have a weight of at least 10mg. We refer to silicone components under 10mg as micro injection molding.
Clean room
Clean room
In order to have a controlled environment for the production of the purest silicone parts, starlim has its own clean room. This is certified according to the classes ISO 14644-1 class 7 & 8 as well as GMP class C&D.
Production
Production
In the fully automatic injection molding process, one-component and multi-component parts are made from silicone at starlim. Production takes place at the Austrian locations in Marchtrenk, Weißkirchen and Lambach as well as in our Canadian branch in London / Ontario.
