How to Choose Suitable Materials for Molds of Silicone Rubber O-ring ?
Rubber O-rings are used in hydro-pneumatic systems and various mechanical equipment and components. They play a sealing role in static or moving conditions under specified pressure, temperature, and different liquid and gas media. Silicone sealing ring is mainly used for waterproof sealing and preservation of daily necessities such as fresh-keeping boxes, rice cookers, water dispensers, lunch boxes, heat preservation boxes, water cups, coffee pots and so on.
Normally aluminum alloy or steel is applied for mold making of rubber O-rings. Aluminum alloy is light (suitable for exporting and saving international transportation costs), easy to be machined, while it has a low mold life shots. It usually meets the needs of low-volume production. While mold made of steel is more suitable for mass production needs.
