Qingdao Kechuang Plastic Machinery Co., Ltd. vacuum sizing method, summed up the past experience, innovation and development of a new generation of anti-corrosion pipe insulation PE vacuum equipment. PE anti-corrosion pipe insulation production line machinery using 90 and 150 production lines; 90 production line range φ110mm --- φ655mm (tube skin diameter); 150 line production range φ760mm --- φ1860mm (tube diameter).
Qingdao Branch of a PE sheath casing insulation production equipment are extruder, nose, mold, vacuum shaping slot, tractor, etc., with a simple production process, reliable technology, technology more mature, and has a high safety performance.
PE anti-corrosion insulation vacuum tube production line technology to improve the old technology manufacturing defects, so that the production pipeline more concise, the appearance looks more perfect, very thick wall thickness, the incision is also very neat, no additional air seal, sealed air in the mouth does not require secondary processing , Will not cause a lot of waste, PE anti-corrosion pipe insulation vacuum device has a high productivity, efficiency than at least doubled in the inflation process, while saving a lot of manpower and environmental resources, PE anti-corrosion pipe insulation vacuum equipment is large Diameter pipe insulation buried in the ideal production equipment.
Qingdao Branch of a plastic Machinery Co., Ltd. is China's leading manufacturer of anti-corrosion insulation pipe production line with the professional manufacturers, welcome from our wholesale cheap machine.

The effect of plastic sheet extrusion machine on the thermoforming of plastic sheet
1 The thickness tolerance of the extruder makes the thickness of the plastic sheet non-uniform, the thickness tolerance of the raw material manufacturing part is about ±5%, the tolerance percentage of thickness less than 2mm is slightly larger, and the thickness is less than 5mm. If it is to produce large quantities of thermoformed materials, tighter tolerance values should be used. The advanced extruder production line is equipped with an automatic thickness feedback control system so that the thickness of the film is from 0.25 to 1.0 mm and the thickness tolerance is ±0.005 mm.
2 If the melt temperature of the extrudate is too low or the calender roll is too cold, the smooth surface of the sheet may become rough or orange peel when heated on a thermoforming machine.
3 Too high traction speed will result in a high degree of orientation in the longitudinal direction.
A very low internal stress in the 4 sheets caused the product to collapse when heated.
5 Too much melting marks Mark marks on the calender roll, such as regular transverse stripes on the film or sheet.
6 The slight scribing of the hanging material on the head of the extruder bulges as the sheet heats.
