Vacuum Suction Molding: Paper and plastic products is the most popular method. According to its structure, there are three different ways: drum, flip, reciprocating lift.
Drum type: continuous rotation production, high production efficiency, large investment in mold, mold machining precision, high precision machining equipment requirements, a set of eight sets of concave punch die, the need to use CNC machining center mold, long processing cycle, Big investment. Because it is continuous production, suitable for large quantities of stereotypes products, if the plate, plate, wine care, egg care. For industrial molding due to non-standard production, quantity, small batch, mold investment is not so large.
Flip: Reversed drum production is less efficient, suitable for industrial production of bulk and non-standard batch production, but because it is a set of concave die with two sets of punch, need to use CNC machining center mold, mold investment is large Long period.
Reciprocating type: the production efficiency is lower than that of the drum, and the return type is not much difference. It is the commonly used equipment of the current common wind. Because this equipment only needs a set of concave die supporting a set of punch, it does not need CNC machining, Suitable for non-standard, small quantities, fast-cycle industrial packaging products (industrial packaging products mold production cycle usually within days).
Grouting method: Grouting method is based on different pulp packaging products, calculate the required amount of slurry (material) and quantitative injection molding cavity, adsorption molding. This molding method for little change, stereotypes of standard products, commonly used in tableware molded products, due to stereotypes difficult to grasp, in non-standard Zhisu packaging (industrial packaging) do not use this molding method.
