Specification of the sjsz80/156 extruder
Performance features:
Screw: Big output & l/d ratio. Two stage unique design effects, with low temperature plastication concept.
Barrel: Barrel is made of special steel alloy, and is equipped with aluminum thermal foil with air cooling system.
Gearbox: Gears are made of steel alloy with heat treatment and are finished with surface precision grinding. By using oil injection cooling system, it reduces noise when operating under high rpm and enhances the life span of gears.
Motor: Ac motor, selected famous brand products. Controlled by abb inverter.
Control system: Adopt selected high quality and famous brand products from europe, and japan manufactures. Machine works more stable and longer working-period.
Performance introduction: Pvc (wood plastic) foaming material is a new man-made material, which has excellent chemical stability and wood physical properties. Corrosion resistance, high hardness, high strength and smooth surface. It can completely replace wood and alleviate the tension of wood. And it can be constructed with general wood processing tools. The product is waterproof, fireproof and anticorrosive, does not absorb water, is light in weight, and has the properties of heat preservation, sound insulation, insulation and shock resistance.
It can be hot formed or bonded with other materials.
It is suitable for secondary processing such as film pasting, printing, embossing and sprayin which is widely used in the construction industry and completely replaces wood formwork and bamboo formwork; wood plastic building formwork has been used for many times; low water absorption; non combustion supporting; recyclable and other advantages
Scope of application: Widely used in construction industry and advertising decoration industry: Spray painting, display board, screen printing, computer lettering, signs, light boxes, etc. Building decoration industry: Indoor and outdoor decorative panels, commercial decorative frames, room partitions, ceiling panels, cabinet, bathroom cabinet ceiling panels, etc. Transportation industry: Ships, aircraft, passenger cars, train carriages, ceilings, car core layers, interior decoration boards and other fields.
One set of extrusion die
Form:
Hanger type mold, equipped with mold hanger.
Die material:
It is made of high-quality alloy steel 5crnimo forgings, and the surface of the inner runner is chrome plated and polished.
Mold specification:
The mold structure adopts imported technology, and the inside of the mold cavity is plated with hard chromium and polished to a bright mirror. The width of the lip die is adjustable with a baffle plate. Stainless steel electric heating rod is used for heating, with uniform discharge and good stability. The width of the die lip is l = 1350mm, the maximum width of the product is l = 1220mm, and the thickness of the product is δ= 4-20mm。
Temperature measuring element:
Use thermocouples. The temperature control instrument is japan omron intelligent temperature control meter. Zone 7 is 35kw in total
Die lip temperature control:
The temperature of the die lip is controlled by oil; heating power: 12kw; pump power: 0.75kw; 6 in and 6 out; stainless steel temperature resistant pipe
