First of all, Goodbon cars are marked with vacuum coating and thick film blister technology. The size of the vacuum pump used in the water pump mainly depends on the area of the suction port of the mold. In fact, the power of Jin Woo air pump for single machine is 0.75kw-5.5kw, and it is better to use vacuum system for many manufacturers.
The volume of vacuum tank should match; Generally, a pump with a molding area of 7 10*920~ 1225 (mm) and a molding material thickness of less than 1.5 mm and 100 is enough; If the molding area is large, the vacuum pump can choose 160 or 200 in addition to increasing the caliber of vacuum tank and vacuum valve; PET with a thickness of 0.8~2.0 mm should achieve ideal molding effect.
Thick sheet blister: a plastic processing technology. The main principle is that the flat plastic hard sheet is softened by heating, then adsorbed on the surface of the mold by vacuum, and then cooled to form.
I hope my answer is helpful to you. I mainly go to the vacuum coating site of Goodbon logo to communicate with technicians.
