POLY-TOOLS bennewart GmbH has extensive experience in the construction of blow molds. Before manufacturing a new tool, the clamping force and size of the machine are always checked to optimally match the blow mold to the respective machine. Additionally, we offer the option to design blow molds for use on multiple machines.

Our blow molds can be produced in all variants for volumes ranging from 1 ml to 200 liters and are compatible with all blow molding machines available on the market.
