Fully automatic molding machine ( Also called automatic plastic 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. Using vacuum suction vacuum pump, PVC, PET, thermal plasticity after heating softening plastic sheet after mold suction shaped into various shapes of vacuum enclosures, blister tray, blister, etc. Automatic vacuum 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 accurate, thermocouple, temperature controller. Whether the installation is not correct 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, suction phenomenon: high temperature, heating time is too long, the 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, covering the surface of workpiece is folding and can not smooth or Angle: the film is not straight, the film quality is bad, the workpiece polishing is not good, glue spray too much, workpiece under the touch panel is too low.
