Pressure molding machine troubleshooting - Union star packaging machinery

Automatic pressure forming machine is by heat after plasticizing of PP, PE, PET, PVC, HIPS and other thermoplastic coil made into various shapes of senior decoration box, box packing machine and other products. Exercise of vacuum pump, vacuum suction will soften after PVC, PET, such as hot plasticity plastic sheet after mold suction moulding all shapes of vacuum enclosures, blister tray, blister, etc. Automatic pressure forming machine troubleshooting way: 1, membrane absorption does not reach the designated position: not enough vacuum, gas leakage, temperature, posted on the rest of the film is too thin, workpiece material, workpiece concave deep beyond the lift of membrane, suction time too short, membrane no pushovers, workpiece interval too close. 2, temperature measurement is not accurate, thermocouple, temperature controller. Whether the installation is not accurate and damage. 3, broken signs: high temperature, heating time is too long, the film quality is bad, no heating. 4, don't start the machine: the input wires, power cords, voltage is not enough. 5, not to be when the membrane absorption down l: electromagnetic valve or valve is on hand. 6, the total power switch trip: heating box input wire leakage, leakage, distribution box outside the wire on the device, electric leakage, etc. 7, don't come on vacuum degree of work: gas path, hand valve or electromagnetic valve is not closed, vacuum pump motor belt is loose, damage of vacuum gauge. 8, the workpiece appearance has broken and can not smooth or Angle: membrane without straightening wuhan site manufacturing, film quality is bad, the workpiece polishing is not good, glue spray too much, workpiece under the touch panel is too low.
