Application
The pin barrel cold feed rubber extruder is rubber processing machinery engineered for the extrusion of various semi-finished rubber products. Some of the items that can be produced using this equipment include, O-rings, seal rings, sealing elements, rubber blankets, rubber strips, and tires and tire components. The equipment is highly versatile and sees use in any number of industrial applications requiring outstanding efficiency and production output.

Product descriptions
1. The screw is made from 38CrMoAIA materials with nitride depth 0.5-0.7mm and hardness HV950-1000.
2. The extruder’s feeding cylinder is composed of a rear body, front bushing and rear bushing. The structure is a jacketed cast iron style.
1. Rear body utilizes cast steel. It contains a cavity where temperature control circulating water can flow through for the cooling of the rear body. In addition, bushing and feeding devices are also placed within the rear body.
2. Bushings are made from 38CrMoAIA materials. The internal surface hardness is HRC65-70 with a hard layer thickness of 0.5-0.7mm
3. The feeding device is composed of a feeding roller, feeding roller cover, bearing support, gear pair, bearing, and squeegee knife.
Feeding roller surface is treated with a hardening process. The outer surface of the feeding roller is equipped with a rubber return trough on both ends to prevent rubber from entering the support bearings.
A squeegee knife is also provided to scrape rubber materials on the roller cylinder surface. The knife is fixed on the roller cylinder with adjustable spacing.
Feeding mouth is rotated to open. The feeding rollers feature grease lubrication to achieve optimal effectiveness.
4. Roller cylinder adopts 38CrMoAIA materials. Its surface is processed through a nitriding treatment. The internal surface hardness is HRC65-70. The hard layer depth is 0.5-0.7mm. Along the cylinder surface there is axial path for temperature control circulating water which serves for heating and cooling the cylinder.
5. Reducer features hardened gears with a level 6 transmission accuracy. The reducer is also equipped with a gear pump with a forced lubrication system which has the function of spraying and oil cooling.
