Production process
Here is the blister packaging ah, here is the blister packaging, I still can not find the blister packaging, ask around where there is if you tell me the blister packaging web site, the blister packaging is quite difficult to find, I really need the blister packaging, who can find the blister packaging, tell me the blister packaging web site, thank you to tell me the blister packaging, to find the blister packaging is quite difficult to find! easy ah, here there is a blister pack ah, here there is a blister pack, I still can not find a blister pack, everywhere asking where there is the words tell me the blister pack web site, blister pack is quite difficult to find, I really need blister pack now, who if you can find a blister pack, tell me the blister pack web site, thank you to tell me the blister pack, to find the blister pack is quite difficult to find the ah, thank you ah
1: mold production and processing: according to the requirements or sample specifications, the first to make a good blister mold, general conditions, are the use of gypsum production of blister packaging molds, but there are also wood and metal carvings of the product as a mold, gypsum molds made, the first to let it dry naturally or dry completely, and then according to the product surface convexity and concavity of the specific situation, with 1-2 mm drilling flowers in the non-convex places that do not affect the product packaging model. Affect the product packaging model of the low-concave drilling many small holes, if the box and other products, but also around the edge of the drilling some small holes, so that the production of blistering, the air can be pumped out, the mold drilled holes, but also the gypsum mold for hardening, hardening method is to be saturated with concentrated alum soaked in liquid and then drying.
2: mold treatment after drying completely, the mold will be loaded into the vacuum chamber on the upper iron plate, and then according to the size of the mold, the plastic sheet will be loaded into the size of the applicable specifications, and then this sheet into a heated wooden cabinet, so that it is completely fixed, and then the wooden cabinet together with the plastic sheet placed in a constant-temperature furnace for softening treatment.
3: the softening treatment of the plastic sheet together with the wooden cabinet, placed in a vacuum chamber, open the suction switch, the vacuum chamber air suction pumping clean, to be cooled down after the plastic sheet, that is, the same with the mold of the concave packaging or process molds.
4: blister packaging finishing; will produce products for trimming and finishing that is the finished product, and then after packaging can be sold.
