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.
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.
In our in-house tool shop, the molds for the injection molding production of the starlim are designed and built. This makes us flexible and independent.
Receiving the first near-series LSR parts from starlim after just 10 days is possible thanks to rapid tooling from sterner. This concept was developed in order to be able to offer customers the first injection molded parts within a short period of time.
With the help of a test tool, we can manufacture the first LSR injection molded parts for starlim’s customers under series conditions within a very short time.
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.
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.
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.
