About Us

Polyshot Corporation is a manufacturer of highly engineered Hot Runner Systems and has been in business since 1989.

Polyshot has developed a technology to fuse two or more steel plates together to create internal flow paths. Polyshot’s technology allows these internal flow paths to withstand very high injection pressures and external forces while still maintaining integrity of the brazed joint.

Over time, Polyshot was asked by several of its Hot Runner customers if it would use the same fusion technology (vacuum brazing) it uses to produce its manifolds to fuse mold cavities and cores for conformal cooling for them. Many brazed cores and cavities later; this brazing service has taken on a life of its own and is a value added service offered to our customers.

An email comment from a Polyshot Brazing Customer in the Midwest USA:
