Fold in half Blister packaging It refers to one kind of blister packaging, also known as double buckle blister. The materials are mainly PVC, APET, PETG, PP, etc.
It is made by adding buckles on the mold, and the workmanship is very fine. However, the two ends of the product are buckled directly, which is called folding blister. The feature is that the product can be better packaged but looks more beautiful. If necessary, staples can also be used. In addition to the folded blister packaging products, there are three fold blister packaging, and the three fold blister packaging is the same principle as the folded blister packaging.
Make samples, Blister packaging manufacturer There is a blister mold department, which is also a step in the production of blister molds. The mold material is gypsum powder. (It is difficult to make the folded plastic mold, especially the folded plastic mold, so the technicians should carefully do a good job of the folded plastic mold.). The sample can be made only after the technician carefully makes the sample mold according to the customer's requirements. However, copper mold and upper mold base are reproduced.
The outer surface dimension precision of plastic parts formed by die forming method is high, and it is generally used for plastic parts with small forming depth. If the depth of the plastic part is very large, especially for small plastic parts, its bottom will become significantly thinner.
For blister parts requiring no thinning of bottom thickness, punch can be used for vacuum forming. The principle is that the clamped plastic sheet is first heated and softened under the heater. When the heated sheet first contacts the punch, it is cooled and loses the thinning ability. When the material continues to move downward until it completely contacts the punch; Then the vacuum pumping starts, and the edges and surrounding areas are formed by thinning. Punch vacuum forming is mostly used for thin-walled plastic parts with convex shapes, and the precision of the inner surface dimensions of the molded plastic parts is high.
The principle of successively vacuuming the concave and convex die is to first fasten the plastic plate on the concave die for heating, then move the heater away after softening, and then blow compressed air through the punch, while the concave die vacuuming makes the plastic plate bulge, and the punch is inserted downward into the bulged plastic plate and evacuated from it, at the same time, the concave die is filled with compressed air to make the plastic plate stick to the outer surface of the punch for forming, This method can be used to form deep cavity plastic parts because the softened plastic plate is blown out to extend the plate before forming, so the wall thickness is relatively uniform.
After the product is produced, it is connected together in one piece. The product should be separated first with a big knife, and then folded in half. Generally speaking, the upper and lower knife dies are used for punching and folding blisters. After folding in half, the punch is used to directly cut off the peripheral materials of the folded product, which is a finished product of folding blisters.
