Blister packaging molding
According to the principle that P V C film (hard sheet) is heated through the mold and is formed into the desired shape and size by compressed air or vacuum, the following aspects should be solved when there are problems in the formed bubble caps
(1) Whether P V C film (hard film) is qualified product;
(2) whether the temperature of the heating device is too high or too low;
(3) whether the surface of the heating device is adhering to P, V and C;
(4) whether the forming mold is qualified, whether the forming hole is smooth and whether the pores are unobstructed;
(5) Whether the cooling system of the molding mold works normally and effectively;
(6) the vacuum degree and exhaust rate of the roller negative pressure forming can reach the normal value, and the pipeline has no abnormal loss;
(7) whether the compressed air formed by plate positive pressure is clean and dry, whether the pressure and flow can reach the normal value, and whether the pipeline has abnormal loss;
(8) Whether the flat plate positive pressure molding mold is parallel to clamp P, V and C belts, and whether there is air leakage phenomenon.
