The molding process of the plastic suction machine is to use the vacuum suction produced by the vacuum pump
to heat and soften the hot plastic plastic sheet, such as PVC, PET, PETG, APTT, PP, PE, PS, into various shapes
of vacuum cover, or attached to the surface of various shape products.
Blister is divided into thin sheet Blister and thick sheet Blister according to sheet thickness
The common failure of the machine is explained:

1,The machine does not start: the input wire is blocked, the power cord is reversed, and the voltage is not enough.

2,Temperature measurement is inaccurate: thermocouple, thermostat, incorrect installation and damage.

3,The working vacuum does not come: the gas path is blocked, the hand valve or solenoid valve is not closed,
the belt of the vacuum pump motor is loose, and the vacuum meter is damaged.

4,General power switch trip: the heating box top input wire leakage, distribution box leakage,
external wiring on equipment, motor leakage.

5,The suction film suction film is not in place: vacuum degree is not enough, air leakage, temperature is not enough,
film is too thin, the workpiece is attached to other materials, the depth of the workpiece is more than the lift of the
film, the suction time is too short, the film is not pulled up, the workpiece distance is too close.

6,The surface of the work piece is folded and unsmooth or can not be wrapped in the corner. The film has no straightening,
poor film quality, poor grinding, too much glue spray, and the underplate under the workpiece is too low.

7,The film is pulled down when the suction is not reached: whether the solenoid valve or hand valve is open.

8,Absorption phenomenon: temperature is too high, heating time is too long, the film quality is not good, no heating.
