SJSZ35 Conical Double Screw Extruder for Japan

This SJSZ35 Conical Double Screw Extruder is specially designed according to Japan customer’s requirements, it equip with 35mm diameter double screw, durable gearbox, servo motor, high-precision temperature control system, and advanced material feeding mechanism. The extruder's screw design ensures efficient plasticizing and mixing performance, while the robust gearbox provides reliable power transmission and long service life. The servo motor enhances operational accuracy and energy efficiency, making the equipment suitable for a wide range of processing needs. Additionally, the integrated temperature control system maintains consistent heating and cooling, ensuring stable output quality during production.

This extruder is designed as a co - extrusion machine for manufacturing PVC window profiles. Thus, we also designed a hydraulic system that can effortlessly adjust the height of the extruder. The hydraulic system ensures precise height adjustments, allowing operators to optimize the extruder's position for different production requirements. This adaptability enhances operational flexibility and reduces setup time when switching between various profile dimensions. Furthermore, the integration of advanced sensors within the system provides real-time feedback, ensuring accurate positioning and minimizing potential errors during adjustments. The robust design of the hydraulic components guarantees durability, even under continuous industrial use, contributing to the overall reliability of the equipment.

The whole unit utilizes PLC + touchscreen control, incorporating real - time monitoring of several parameters like temperature, rotational speed, and pressure. It backs parameter storage and one - click retrieval, providing user - friendly operation that satisfies the strict demands of high - end customers for equipment automation and stability.

The barrel is characterized by a segmented heating and cooling structure that comes with an independent temperature control module. A dual - path vacuum exhaust system is installed underneath, which can effectively remove volatile components and moisture from the material, thus improving product density and surface quality.

Features and Advantages

1. High adaptability: Exceptionally versatile, the conical screw design is purpose-built for PVC powder processing. It enables seamless one-step production from raw powder to finished products without the need for granulation, dramatically cutting down on energy usage and manufacturing costs.

2. High stability: A reliable temperature - controlled vacuum system, combined with precise feeding and a high - torque transmission system, guarantees a stable extrusion process. This results in high dimensional accuracy of the final products and meets the strict consistency demands of the premium market.

3. Simple Maintenance: The modular structure design and standardized component selection cut down the complexity and cost of equipment maintenance, while fulfilling high - end customers' demands for equipment reliability and low failure rates.

4. Environmental friendliness and low noise: The whole unit uses a low-noise motor and precise transmission components, leading to minimal noise during operation; the vacuum exhaust system effectively cuts down exhaust emissions, meeting the requirements of environmentally-friendly production. 

Typical application scenarios

This SJSZ35 conical double screw equipment excels in the extrusion molding of PVC pipes, profiles, sheets, and custom door/window profiles. It is also highly suitable for the modification and extrusion processing of other heat-sensitive plastics, making it the perfect choice for manufacturing high-precision plastic products in small-to-medium production batches.
