The 65 Extruder — the Efficient "Heart" of KingJoy Production Lines
November 09, 2026
In a plastic extrusion line, the main extruder is the power core of the entire system, directly determining plasticizing quality, output and operational stability. The KingJoy 65 extruder (65mm screw diameter) has become a common configuration for pipe, profile and panel production lines thanks to its mature screw design, reliable transmission system and precise temperature control.
- High-efficiency screw design: Screw structures optimized for different materials ensure uniform plasticizing and stable melt, balancing output and product quality.
- Wear-resistant and durable: Screw and barrel are made of premium alloy steel with special treatment for excellent wear and corrosion resistance and a long service life.
- Precise temperature control: Multi-zone heating and cooling control keeps temperatures stable, effectively preventing material degradation and product defects.
- Reliable transmission: The hardened-tooth-surface gearbox offers strong load capacity, smooth transmission and low noise for long continuous operation.
- Variable-frequency speed control: Smooth operation and flexible adjustment to suit different processes and output requirements.
- Compact structure: Reasonable layout with easy operation and maintenance, convenient for matching with various auxiliary machines.
The KingJoy 65 extruder can be widely matched with PVC pipe, profile, panel, sheet and pelletizing extrusion lines, and can be customized according to the customer's materials and process requirements.
As a professional plastic machinery manufacturer, KingJoy offers complete matching capability from main machines to auxiliary equipment, and the 65 extruder integrates seamlessly with the company's full range of production lines. From selection and commissioning to after-sales technical service, KingJoy provides full-process support to help customers win in the market with stable and reliable equipment.
