Suction molding machine troubleshooting methods

All active suction molding machine ( Also called full active thermoplastic molding machine) Is through the heated plasticization of PVC, PE, PP, PET, HIPS, thermoplastic plastic coil made into various shapes of advanced packaging decoration machine box, box, 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. All active suction molding machine troubleshooting methods: 1, membrane absorption does not reach the designated position: not enough vacuum, gas leakage, temperature, membrane is too thin, posted on other material of workpiece, workpiece concave depth over the lift of membrane, suction time too short, membrane no pushovers, workpiece is too close. 2, temperature measurement is not correct: thermocouple, temperature controller. Whether the installation is not accurate and damage. 3, the total power switch trip: heating box input wire leakage, leakage, distribution box outside the wire on the device, electric leakage, etc. 4, to break the signs: high temperature, heating time is too long, film quality is bad, no heating. 5, don't start the machine: input wires, power cords, voltage is not enough. 6, not to be when the membrane absorption down l: electromagnetic valve or valve is on hand. 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 website production, film quality is bad, the workpiece polishing is not good, glue spray too much, workpiece under the touch panel is too low.
