Features:

1. Screw is made of best 38CrMoALA, its hardness is higher generally than HRC62 ( 60-65 ), Depth of nitrogen is higher than 0.55-0.7 mm ( 0.4-0.7 )

2. Bush is also made of 38CrMoALA, its hardness is generally higher than HRC66( 65-70 ), Depth of nitrogen is generally higher than 0.55-0.7 mm ( 0.4-0.7 mm )

3. Feeding device is made of feeding roller and feeding barrel, Feeding roller is driven by gears and its structure resembles Italy type. The rubber will never leak out, then it is never impossible for that the rubber enters into the bearing bush.

Specifications

The rubber extruder is used for extrusion of various rubber porducts and rubber feeding .

1 Pin-barrel cold feed rubber extruders are made by the Company with introduced technologies. Different extrusion heads are appliedto extrude various half-finished rubber products.The machines can also be used to feed fubber to mangiers.

2 The barrel is composed of several zones. in the feeding zone. The spiral slots work with the side rolls to enhance feeding capability. In the plastication and extrusion zone, different numbers of pins are fitted. The barrel is of the dual metal structure and bored circumferentially.

3 The screw is processed and polished with the foreign-made milling machine and is featured by excellent geo-metric precision. Nitrogenation treatment makes it more wear-resistant.

4 The gears in the reducer are made of alloyed steel, whose teeth are hard.

5 A hot water circulation device automatically controls temperature in each zone.

6 The machine is driven by a DC motor.

7 The advantages of the machine include better plastication result, higher extrusion capability, lower temperature of the outgoing rubber and smooth operation .

8 The Company also make special feeding unti for the pin-barrel cold feed rubber extruder to convey rubber slabs.
