Barrels

In order to adapt to the requirements of different processes and materials, Many types of barrels are available with different Design and levels of resistance to abrasion and corrosion. Nitride Barrels Nitride Alloy Steel as base materials in all Plastics industry, We are using EN-41b MUSCO Material For all standard barrels. Thickness from 0.5 to 0.7 mm, hardness 65-68 HRC, Principle of nitride process is based on penetration of atomic nitrogen into the peripheral steel layer with the temperature of 550 C and it causes increasing the peripheral toughness by formation of nitrites and by depositing the nitride atom in areas between grids which causes grid tension Nitriding is a heat-treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface. The applications of Nitrided Barrel are injection molding, extrusion molding, and blow molding. By using high-quality grade nitriding steel, with 72 hours of nitriding process, the nitrided layer will help the barrel to get better performance by being corrosion and abrasion-resistant. Nitrided barrels have a very good wear resistance until the surface the hardness is worn away.

Bimetallic Barrels

If the lifetime of the barrel is not long enough because of abrasive or corrosive additives or fillers, the right solution is Bimetallic barrel.

Groove Feed Vented Barrel & sleeve

Feeding grooves are used in most of today's extrusion applications. With the use of “Soft” or “Hard” feeding grooves
