Liquid injection molding

The technology

The technology Liquid Injection molding (LIM) is used to manufacture elastomer molded parts made of liquid silicone rubber (LSR). The special properties of this material make it suitable for a large number of applications, from medical technology to the food sector, to electrical engineering or mechanical engineering, or even in sanitary engineering as well as sports and leisure. This comes as no surprise, since LSR is tasteless and odorless, biocompatible, plasticizer-free, and also has excellent thermal properties.

This new technology allows us to respond to the increased demand in the market for silicone components, which means we can satisfy the needs of our customers even better

Wide range of offerings

Medical Technology

Liquid silicones are tasteless and odorless, plasticizer-free, and have excellent biocompatibility. They are therefore best suited for different products in the field of medical technology, such as breathing masks, teats, hoses, or seals.

Baby care

We set the highest standards for baby products, in particular: Teats, pacifiers, teething rings, and breast pumps as well benefit from the special properties and proven quality of liquid silicones.

Toys

Toys, hinges, dampers, parts for boats and vehicles, and many more can be quickly and easily produced through liquid injection molding in top quality, and precisely in accordance with our customers' wishes.

Appliances

Razors, toothbrushes, touchpads, casings or housing parts – household appliances such as these can be customized using liquid silicone rubber that can be colored according to taste.

Automobile Industry

Products from liquid silicones are characterized by good electrical insulating properties as well as good environmental compatibility – plugs, seals or interior elements with LSR parts are therefore ideal for the specifications of the automobile industry.

Sanitary & Household Sector

Very good weather and aging resistance have increased the demand for showerheads, aerator applications or filters with LSR components in the sanitary and household sector.

What are silicones?

Silicones belong to the group of organosilicon compounds and are classified in the plastics groups of elastomers. Depending on the type of vulcanization and viscosity of the base polymer, a distinction is made between different grades of rubber as well as high-temperature and low-temperature vulcanization. Because of its special properties, Greiner Assistec is focusing on LSR, which belongs to the group of high-temp vulcanizing rubbers and exhibits a particularly low viscosity. LSR is a pumpable 2-component mixture and is a superb choice for processing in Injection molding processes.
