Rubber extrusion molding

Principle of rubber extrusion molding: The rubber compound is heated and plasticized within the extruder, subjected to intense shear between the screw and the barrel, and continuously conveyed forward by the screw’s rotation. Under a specified pressure, it is then forced through an extrusion die (also known as a die head) to produce a product with the desired cross-sectional shape. Characteristics of rubber extrusion molding: 1. The rotation of the extruder screw further mixes and plasticizes the compound, resulting in a dense, uniform semi‑finished extrudate; 2. It has a wide range of applications—by changing the die, various cross‑sectional profiles can be produced, as well as pre‑formed semi‑finished products for use in compression molding; 3.

Characteristics of rubber extrusion molding:
1. The rubber compound undergoes further mixing and plasticization as it is conveyed by the extruder screw, resulting in a dense and uniform semi-finished extrudate.
2. It has a wide range of applications; by changing the die, it can extrude rubber profiles of various cross-sectional shapes as well as pre‑formed semi‑finished products for use in compression molding dies.
3. Extrusion-molded products are produced at high speed, with high production efficiency, making them well-suited for automated manufacturing.
4. Extrusion molding is not limited by length, enabling the production of long articles that cannot be manufactured by compression molding due to equipment constraints.
Extrusion of rubber sealing strips—when we talk about sealing strips, we think of their applications in automotive components such as doors, windows, the vehicle body, seats, sunroofs, the engine compartment, and the trunk, as well as their functions of water resistance, sealing, sound insulation, dust protection, freeze resistance, and vibration damping.
