Stack mold is High efficiency more than single mold, greatly reduce the production cost of injection molding. From the structural features, the laminated mold will be more vice cavity combination in a mold, the full use of ordinary injection molding equipment can meet production.

The laminated mould manufacturing requirements are basically the same as common mould. According to the statistics, the manufacturing period of 1 stack mold is shorter than that of two single layer die, and 5% ~ 10%

stack mold is suitable for the large scale production of large quantities of flat production. The smaller the volume of small multi cavity wall, the lower the production cost and so on
