Extrusion application

Extrusion, also known as extrusion, is a plastic molding process and one of the important methods of thermoplastic molding.

 Extrusion is to heat the plastic raw material, so that it is in a viscous flow state, 

under the action of pressure, through the extrusion mold to become a continuous body with a cross-section and the shape of the die, 

and then cooling into a glass state, and cut to get a certain geometric shape and size of the plastic products. 

For example, the material is heated and pressurized in the extrusion machine to make it a molten flow state, and then it is continuously extruded from the mouth die to form, which is called extrusion. This method can produce tubes, tubes, rods, films, sheets, profiles, wires, etc.

Application field:

Automotive industry: Rubber extrusion products have a wide range of applications in the automotive industry. For example, car seals are used to seal doors, Windows, hoods and other parts to prevent noise, dust and moisture intrusion. In addition, rubber extrusion is also used in the manufacture of automotive rubber tubes, protective strips, decorative strips and other parts. 

Electronics and electrical appliances: Rubber extrusion products are also used in the field of electronics and electrical appliances. For example, rubber extrusion insulation strips are used for insulation protection of wire and cable, and rubber extrusion seals are used for sealing and protection of electrical equipment. In addition, rubber and plastic extrusion is also used to make electronic products shell, keys, connectors, etc. .

Packaging and logistics: Rubber and plastic extrusion products are also used in the field of packaging and logistics. For example, the rubber and plastic extrusion corner protection strip is used for the protection of packaging boxes, and the rubber and plastic extrusion pallet gaskets are used for anti-slip and buffering of logistics pallets. In addition, rubber extrusion is also used to make gaskets, filling materials, etc.

 Construction field: Extruded polystyrene board (XPS) is a common extrusion product, mainly used in the field of building insulation, such as wall insulation (external wall insulation, external wall insulation), roof insulation (metal structure roof, new brick and concrete structure building roof, old roof, etc.), which plays the role of heat insulation, moisture-proof waterproof and impact resistance; Floor insulation (including dry floor heating, floor insulation sound insulation); Square ground foundation application;

 It is used in the foundation of the underground wall of a building, the brick wall base or the outside of the wall base for external thermal insulation, and plays the role of thermal insulation, moisture-proof and waterproof 3. Other fields: Rubber extrusion products are also used in many other fields, such as medical equipment, furniture, sports equipment, toys and so on. For example, rubber and plastic extrusion tubes are used in the manufacture of medical catheters, and rubber and plastic extrusion strips are used in the decoration and protection of furniture 2. To sum up, plastic extrusion technology plays an important role in multiple industries due to its flexibility and diversity.
