Silicone Moulding

Silicone Valves:
Silicone valves for WRAS approved or FDA approved valves,
Silicone injection moulding technology, pressure actuated components such as back flow valves

Silicone custom components:
Silicone ring seals, single-wire seals, housing seals, individual inner grommets, etc. are all responsible for providing watertight seals that last for the lifetime of the product. These parts must be able to withstand high temperatures without detriment to the part’s mechanical properties.
Silicone over-moulding to plastic and metal is also common.

Silicone O-rings:
Silicone O-rings for heat applications and medical applications are common. Or silicone O-rings with Unique Geometries.

Silicone bellows:
Extreme temperature resistance makes it ideal for any interior or exterior application. Whether it is a complex shaped component or a simple geometry part, any high-volume part can be manufactured using injection moulding processes.

Silicone Seals or Gaskets:
For high temperature conditions, or where exposure heat may lead to rapid aging.
Silicone seals offer mild oil resistance. For improved oil resistance the fluorosilicone seals should be considered.

Fluorosilicone Seals and Fluorosilicone O-rings:
Fluorosilicone is most often used in aerospace applications for systems requiring fuel and/or diester-based lubricant resistance up to 400°F. Although generally specified for aerospace use, due to its excellent fuel resistance and high temperature stability, Fluorosilicone is also becoming an increasingly popular material for a wider range of sealing applications. It features good compression set and resilience properties, Fluorosilicone compounds are suitable for exposure to air, sunlight, Ozone, Chlorinated and aromatic hydrocarbons.
