- Screw & barrel are special designed, made of 38 CrMoAIA precision processing high quality alloy steel, with precision processing treatment, surface is nitrogen treated, nitrogen depth is within >0.5mm~<0.7mm, hardness is >940, brittleness is not big than grade 2.
- Suitable for use special screw to extruder compound of PVC, PE, LSHF (Low-smoke halogen-free), satisfy customers different technics requirements.
- Adopt high quality hardness gears (JHM series) special gearbox, which has advantage such as big capacity, high precision, low noise, high coefficient of safety, and long working life.
- The main extruder of Dia. 90~200 series adopt independent motor for oil pump circulation and cooling, which is more safe and reliable.
- (Optional part) Special designed material feeding device has drain out exit, it is convenient to change material during line stop, save time and material.
- Cross-head connection is "half-type", easy for assembling work and it is reliable.
- Body heater has three types for customers's choice:
1.) casting AI heater
2.) ceramic heater & cooper fin radiator
3.) new type induction heater

II. SJ30 X 25 ~ SJ200 X 25 series insulation & sheathing extrusion production line
Application:
- This production line is used for producing PVC, PE, LSHF (Low-smoke halogen free) cable insulation layer or sheathing layer.
Main technical parmaters:
Extruder spec.: Dia 30, 45, 65, 90, 120, 150, 200 etc.
Screw parameters: L/D ratio: 25:1 or 30:1
Type: tapered screw, LSHF screw or BM type (user's option)
Whole stainless steel cooling water tank: total length 12-32m (depends on types) unit end is equipped with telescopic water tank.
Traveling distance is 300-600mm
Caterpillar: TQD 100~4000 caterpillar puller (depend on actual type)
Line speed: 30m - 200m/min (depending on actual type)
Tke up and pay-off reels specification: PN500-PN5000 (depend on actual type)
Features:
- The line can be configured and combined flexibly depending on technological requirements, thus featuring easy use.
- Extruder main unit and puller are driven by Z4 DC motor (or frequency conversion motor), controlled by imported full-digital speed-control device.
- Extruder body and head are equipped with RKC temperature control instrument with control-accuracy < ±2°C.
- Pay-off & Take-up adopts new shaftless structure (portal type or gantry type), bobbin loading & unloading without crane.
- Large sheath machine unit adopts front and rear double-hauling, equipped with special synchronous control circuit, ensuring that the cables are not scratched and damaged un water tank.
- The line is controlled by PLC, featuring steady and reliable preformance. It is possible for users to adopt industrial computer (PC) and main-control touch screen.
- The line is centrally controlled, to realize automatic production.
III. TQD series pneumatic belt caterpillar
Application:
- Mainly for usage of wire and cable production line in single or in front and rear double haul-off purpose.
Structure and feature:
- Integral frame has nice appearance which is welded by high quality bending steel
- Equipment transmission is via motor - gearbox - gear reducer - up& low helical gear - hard drive structure, transmission is smooth, high loading capacity, easy maintenance.
- Whole series has more than 10 sizes from 200kg to 15000kg, two kinds of speed regulation structure of Z4 DC motor and frequency motor could be choose at customer' needs.
- Equipped with electronical meter counter, real-time display line speed and length.
- Prepare transmission shaft structure, for matching production of laying up production line, armoring production line, and copper tape screen and lapping production line.
- Tension is controlled by magnetic powder clutch, use for front haul-off device of insulation and sheathing production line, tension is instantaneous adjustable, to prevent cable scrape in the water trough, and insure synchronization and diameter of cable.
- The small size caterpillar has whole frame with movable function, convenient for customer use to special technical requirement, and efficiently increase belt life.
