Rubber extruder

It can be used in the rubber industry for extrusion molding of rubber hoses, heater hoses, wire‑reinforced hoses, inner tubes, adhesive tapes, bead strips, and other rubber products. It is also suitable for supplying hot mixing to small calendering machines. Compared with conventional rubber extruders, cold‑feed rubber extruders offer higher production capacity, lower compound temperatures, reduced electrical energy consumption, superior mixing performance, uniform plasticization, and greater output. The rubber hose extruder boasts excellent self‑cleaning properties. Its screw is made of 38CrMoAlA steel, quenched and tempered to achieve a hardness exceeding HV900. The extruder’s output of various products can have its extrusion speed adjusted according to specific production process requirements. The die head is easily removable and capable of producing multi‑cavity profiles in multiple sizes. In a cold‑feed rubber extruder, an electric motor drives the screw via a reducer; the screw rotates within a barrel fitted with pins. At the initial section of the screw, a side‑pressure roller is installed, rotating in the opposite direction to the screw to forcibly feed the rubber compound, which is then extruded from the screw’s discharge end. Notably, belt drive is employed between the motor and the reducer with appropriate speed reduction, while a standard horizontal hard‑toothed‑surface reducer is used. The driving gear of the side‑pressure roller is positioned by a radial bearing, and the roller itself is mounted on a hinged cover that can be flipped downward for maintenance. Spiral return channels are machined into the side of the bearing housing, and the pin‑equipped barrel features a symmetrical design.

Rubber extruder

Can be used in the rubber industry, rubber pipe, warm air pipe, wire clamp hose, inner tube, tape, sub-mouth belt and other rubber products extrusion molding. Can also be used for small calender hot supply. Compared with general rubber extruder, cold feeding rubber extruder has the characteristics of high production capacity, low temperature of rubber material, less energy consumption, good mixing effect, uniform plasticizing and high yield.

The rubber tube extruder features excellent self-cleaning capabilities. Its screw is made of 38CrMoAlA steel and, after heat treatment, achieves a hardness exceeding HV900. The extruder can produce a wide range of products, with extrusion speed adjustable to meet specific production process requirements. The extruder head is easily disassembled and offers various extrusion specifications and cavity configurations.

Cold feeding rubber extruder, the motor through the reducer deceleration drive screw rotation, screw is placed in a barrel with a pin, in the beginning of the screw, the side of the press roller, and screw for relative rotation, the rubber forced feed, and extruded from the end of the screw, the characteristics of the motor and the reducer between the belt drive and appropriate deceleration, The reducer adopts standard horizontal hard tooth surface reducer, the driving gear of the side press roller is positioned with a radial bearing, and the side press roller is fixed on a valve that can be turned down and opened through the bearing frame. The side of the bearing frame is processed with spiral rubber groove, and the barrel with pins adopts symmetrical structure.
