1.head die part
heating way: Aluminum-casted heater
2.Net change unit
by hydraulic system ,it inculdes double filters.
3.Screw& barrel material
38CrMoAIA after nitrogen treatment with optinum hardness, strong corrosion resistance and long service lifetime
4.The SJ120/33 extruder technology in the manufacture of precision extruders for mass production of high quality
plastic sheet
The connection between motor and gear is direct , through an elastic joint , suitable for absorbing bumps and vibrations .
5.The extruder motor is AC or DC , complete with motor-ventilator . the extruder motor is plasced under the
barrel to reduce overall dimensions , while the motor drive . variable speed and constant torque , is included in the general control panel of the extruder . the venting plant is made up of liquid ring , vacuum pump , flowmeter for pump protection , a water-reclaiming system can be optionally supplied , the flat die can be supplied either for sheet or for plate production , the available die widths ranges 700 to 4000mm , the thickness varies from 0.3mm to 8mm.
6.The modes of the three-roller calendar: According to the material properties, horizontal, vertical or inclining angle of 45 degree can be freely up and down Internal roller temperature control using a unique flow channel, so that the stability of uniform distribution roller. The independent oil temperature control for three roller to ensure more stable and exact control.
7.Thickness control of board: adjusted by the
screw or bidirectional controlled by clamping roller, can accurately control thickness of the
board.
8.Cooling Bracket: According to product specifications, configurations with different specifications of the stainless steel cooling roller
9.Edge-cutting devices: Trimming can be divided into manual and automatic, three-dimensional configuration tool adjustment device, width adjustable.
10.Cut off machine: Saw cutting or knife cutting, thin type and non-friable type
sheet generally usually knife cut, adopted high-quality alloy cutting tools, sharp and durable. The cutting machine can precisely contrlo the cutting lengh. The machine equipped with meter counter can set the length of product.
