Profile Extrusion is produced by forcing uncured rubber through a die under heat and pressure, to form a part with a uniform cross section. This uncured rubber is then run through a heating unit to initiate the chemical cross linking reaction that causes the rubber to cure.

This production line can productively produce profile product. It has high output capacity, durability and plastic evenly with recent technology and optimized design.

Process:
The plastic is fed in the machines, the material is conveyed continuously forward by a rotating screw inside a heated barrel being softened by both friction and heat. The softened plastic is then forced out through a die and directly into cool water where the product is solidified. From here it is conveyed onwards into the take-off rollers, which actually do the pulling of the softened plastic from the die.
