Screw Diameter 90mm Rubber Extruder Machine For Producing Rubber Wiper Rubber Strips

Rubber extruder screw diameter is 90mm for producing rubber wiper rubber strips

Machine Introduction:

The 90 model rubber extruder manufactured by Beishun Company is a kind of equipment used for rubber processing. Here are some introductions about it:

- Basic parameters:
- Head center height: usually 1000mm.
- Screw outer diameter: 90mm.
- Screw aspect ratio: generally 14:1.
- Screw compression ratio: 1.42.
- Screw-barrel clearance (double-sided): between 0.25 - 0.365mm.
- Screw speed: 4.5 - 45 rpm.
- Production capacity: about 150kg-450kg/hour.
- Motor model: for example, yct315-4a, power 55kw, speed 132 - 1320 rpm.
- Working principle: Through the rotation of the screw, the rubber material is sheared, plasticized and kneaded, so that it is evenly and continuously conveyed to the die under a certain pressure, and extruded into a rubber product with a specific cross-sectional shape at the die. During the forward movement of the rubber along the screw, due to mechanical and thermal effects, the viscosity and plasticity of the rubber change and become a viscous fluid. The working part of the screw is usually divided into a feeding section, a compression section and an extrusion section.

- Structural composition:
- Extrusion system: It is mainly composed of a feeding device, a screw, a barrel, a bushing, etc. It is the main part of the extruder and is responsible for shearing, plasticizing, kneading and conveying the rubber.
- Transmission system: It is composed of an electric motor and a reducer, etc., which is used to drive the screw to rotate and adjust the screw speed according to the process requirements.
- Die head: It is the molding component of the extruder, which changes the rubber from spiral motion to linear motion, and extrude the rubber into semi-finished products of various required shapes under a certain pressure. The die head can be replaced according to the shape of the extruded semi-finished product and different extrusion processes.
- Heating and cooling system: It is used to control the temperature of the rubber during the extrusion process. Steam, water, oil, ethylene glycol, etc. are commonly used for heating, and water is mostly used for cooling. It consists of pipelines, control valves and distributors. If a liquid heating and cooling system is used, pumps, heaters, etc. need to be added.
- Electrical control system: Generally composed of temperature control, speed regulation and detection devices, to meet the needs of extrusion process conditions, and to control and adjust the temperature of each section of the extruder barrel, head temperature, screw speed, drive torque or power, axial force, etc.
- Features and advantages:
- High production capacity: can meet the production needs of rubber products of a certain scale.
- Low rubber temperature: helps to reduce the overheating of rubber during processing and reduce the impact on rubber properties.
- Low power consumption: has good energy-saving effect and can reduce production costs.
- Good mixing effect: can fully mix rubber materials to ensure the uniformity of product quality.
- Uniform plasticization: makes the plasticization degree of rubber more uniform and improves the quality and performance of products.
- Excellent self-cleaning property: the design of the screw and barrel is usually conducive to the flow and cleaning of rubber and reduces residue.
- Adjustable extrusion speed: The extrusion speed can be flexibly adjusted according to the product production process requirements to meet different production needs.
- The die head can be easily disassembled: It is easy to replace and maintain the die head, and it has the function of extruding multiple specifications and multiple cavities, which can improve the versatility and production efficiency of the equipment.
- Application range: It can be used for the extrusion molding of rubber products such as rubber tubes, warm air tubes, wire hoses, inner tubes, tapes, and sub-mouth belts in the rubber industry, and can also be used for hot refining supply of small calenders. It is also suitable for extruding a variety of rubber materials such as silicone, natural rubber, EPDM rubber, and oil-resistant rubber. For example, it can produce rubber sealing strips, rubber tubes, rubber sheets and other products.
