Hydraulic support seals tell the production method of manufacturing O-rings "Extrusion method"

Extrusion is a common way to produce large silicone O-rings. The process involves extruding a silicone material through a die through an extruder to form a shaped seal. Hydraulic support seal manufacturers to tell you about the manufacturing method.

Pre-treatment of silicone materials: Before extrusion, silicone materials usually need to be pre-treated to ensure that they have the required viscosity and characteristics. This may involve mixing, heating and adjustment of the extruder to accommodate different specifications of the sealing ring.

Extrusion molding: The silicone material is fed into the extruder and extruded through the die to form a continuous sealing ring shape. The die head is usually designed according to the required sealing ring section and can be customized according to different needs.

Cooling and cutting: The extruded sealing ring will be cooled and solidified in air or water, and then cut to the required length. This process may require special cutting tools or equipment to ensure the accuracy and quality of the sealing ring.

Inspection and packaging: The finished sealing ring is usually subjected to quality inspection to ensure that it meets the specifications. It is then packaged for easy transport and storage.
