Product drawing six cm, with the mold almost do not shape, do not use the mold on the vacuum suction can be in place, but so that the bottom of the four thin, and the sheet is also cooked, the pro master to help
1 、 the heating temperature of sheet is too lowA, adjust heating time, heating time.B, raise electric furnace temperature. C, check whether the electric furnace is damaged2 、 vacuum eye obstructionA. check that the vacuum eye is blocked and the vacuum hole is adequate. The vacuum hole B. re drilled the vacuum eye on the mold surface to keep it clear.3, vacuum too slow leakA. shorten the pumping time B., change the vacuum pump C. with strong work to check whether the mold is leaking4, the bottom mold and shelf time mismatch.A. appropriate adjustments to the action of the two.5 、 the upper die is improperly matched and the pressure is not in placeA. carefully observe the molding and see where it is not in place.Plastic suction machine (also known as thermoplastic molding machine) is the heating of plasticized PVC, PE, PP, PET, HIPS and other thermoplastic film, made into various shapes of advanced packaging, decoration boxes, boxes and other products of the machine. Using the vacuum suction produced by the vacuum pump, the thermoplastic plastic sheets, such as PVC, PET and the like, which are heated and softened, are absorbed by the mould to form a vacuum cover, a blister tray and a blister shell in various shapes.Plastic molding machine principle: plastic molding called thermoplastic molding, the molding process is mainly produced by vacuum suction vacuum pump vacuum heating and softening after PVC, PET, PETG, APTT, PP, PE, PS and other thermoplastic plastic sheet after mold suction into various shapes of cover, surface or attached to the post various shapes of products. Blister according to sheet thickness is divided into thin film blister and thick film blister.
Check the travel switch at the charging line, and then lubricate the rail
Is the female model bar, should be your upper and lower modules did not tune; re commissioning, the upper and lower die on the OK.
The sheet is PET? PVC can't be packaged with food. The speed is fast, the upper die is in place first. Vacuum delay time is 0, basically no problem, do PP will be more trouble. Hope to help you.
