Product Overview
Industrial extrusion lines are used to convert polymer compounds into continuous products with defined cross-sectional shapes. Depending on the material and end-product requirements, a production line may include a feeding system, extruder, extrusion die, temperature control system, downstream handling equipment, and cutting or winding units.
Our extrusion machinery portfolio covers two main product categories: silicone rubber extrusion lines for continuous rubber profile production and PVC profile extrusion lines for manufacturing rigid or flexible plastic profiles.
Each line is configured according to the material formulation, product geometry, required output, dimensional requirements, and downstream processing method. Extruder specifications, tooling, temperature control, line speed, and auxiliary equipment are determined during technical review.
These systems are intended for manufacturers of rubber sealing products, plastic profiles, electrical accessories, and other extruded components. The appropriate configuration depends on the customer's production requirements and the characteristics of the material being processed.
Silicone Rubber Extrusion Line
Product Overview
A silicone rubber extrusion line processes uncured silicone rubber compounds through an extrusion die to produce continuous profiles, tubes, seals, and other products with a defined cross-section.
The production line can be configured with suitable feeding, extrusion, curing, cooling, and take-up equipment. The curing method and downstream layout depend on the silicone compound, product dimensions, required production speed, and final application.
Key Features and Configuration Options
Extruder and Screw Configuration: Screw geometry, compression characteristics, and drive specifications are selected according to the silicone compound and required output.
Extrusion Die: Die geometry is designed around the target product cross-section, dimensions, and material flow characteristics.
Curing System: A suitable curing configuration, such as a hot-air vulcanization system or another compatible curing method, can be selected according to the compound and process requirements.
Temperature Control: Heating and temperature monitoring arrangements are configured for the extrusion and curing processes.
Downstream Handling: Cooling, pulling, cutting, and winding equipment can be selected according to the product shape and handling requirements.
Line Control: Drive coordination and operating controls can be configured to suit the selected production line and required degree of automation.
PVC Profile Extrusion Line
Product Overview
A PVC profile extrusion line converts PVC compounds into continuous profiles through controlled plasticization, die forming, calibration, cooling, and haul-off. Cutting equipment is used to produce finished lengths according to the required dimensions.
The line configuration depends on whether the application uses rigid PVC, plasticized PVC, or a compatible wood-plastic composite (WPC) compound. Screw design, extruder type, die configuration, calibration equipment, and downstream handling must be selected for the specific material and product geometry.
Key Features and Configuration Options
Extruder Selection: Single-screw or twin-screw configurations are selected according to the material formulation, processing requirements, and intended output.
Screw and Barrel: Material selection and screw geometry are determined by the compound characteristics and expected processing conditions.
Profile Die: The die is designed for the target cross-section and required material distribution.
Vacuum Calibration: Where required, a vacuum calibration table supports profile shaping and dimensional control during cooling.
Haul-Off System: Pulling speed and contact arrangements are selected to suit the profile dimensions and production requirements.
Cutting Equipment: Synchronized saws or other suitable cutting systems can be configured for the required finished length.
Control System: Temperature, screw speed, haul-off speed, and cutting operations can be coordinated according to the selected automation configuration.

Installation, Operation, and Maintenance
Before ordering, buyers should confirm the production line layout, installed power, cooling requirements, compressed air requirements, and available factory space.
Installation and commissioning requirements depend on the machine configuration and the scope of supply. Quotations clearly identify included services, such as installation guidance, operator training, commissioning support, and spare parts availability.
For maintenance planning, buyers receive recommended inspection schedules, lubrication requirements, wear-part replacement procedures, and replacement component availability guidelines. A final utility schedule and layout drawing are prepared specifically for the selected configuration.
