EPDM Or SBR Or NBR Or Silicone Cold Feed Rubber Extruder Machine
With Vulcanization Tunnel
Application
The cold feed rubber extruder is designed and manufactured to
produce semi-finished rubber products of various shapes. The cold
feed rubber extruder machine is used for extruding different shape
of rubber semi-product. The cold feed rubber extruder is widely
used for the production of O-rings, seal rings, sealing elements,
rubber sheets, rubber strips, water stops, rubber pads, rubber
hoses, rubber belts, cables, railway equipment, tires, inner tubes,
and many more. The strength of the machinery comes from the high
level of efficiency and volume of output.
Extruder machine type : hot feed extruder ,pin cold feed extruder
,pin-barrel cold feed extruder ,and rubber strainer.

Product description
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.
3. Rear body uilizes 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.
4. Bushings are made from 38CrMoAIA materials. The internal surface
hardness is HRC65-70 with a hard layer thickness of 0.5-0.7mm
5. 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.
6. 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.
7. 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.
