Construction will begin in May on Polyshot Corp.'s headquarters plant in Henrietta, N.Y., at a business park next to the Rochester Institute of Technology. When the new building is completed this fall, the manufacturer of hot runners will move from its 5,500-square-foot plant a few miles away. President Douglas Hepler said the building in RIT's business and technology park will total 13,000 square feet — 10,000 square feet for manufacturing and 3,000 square feet of office and engineering space.
In the next two years, Hepler plans to begin another expansion at the 5-acre site that will expand the building to 43,000 square feet.
Founded by Hepler in 1989, Polyshot now employs 17. Rapid growth means Polyshot is adding employees — and Hepler said access to skilled engineers from RIT is the main draw for locating the headquarters at the 40-acre industrial park.
"They're looking for companies to place co-op students, and we have a need for co-op students," Hepler said.
Polyshot began with two employees in a tiny office. The company has expanded twice since then into leased facilities, moving into its current headquarters in 1994.
Hepler said Polyshot runs three computer numerically controlled milling centers to cut metal parts, such as hot-runner manifolds and probes. With the expansion, the company will buy more equipment, including a mill with a shuttle table that will allow the continuous machining of manifolds.
Hepler said Polyshot's investment will be more than $1 million, but he declined to be more specific.
In other news, Polyshot has started making a new carbide hot-runner probe for molding abrasive materials such as glass- and mineral-filled resins. Hepler said the probe's construction is unique because the entire flow path and tip are machined from a blank of solid carbide.
Competitors, he said, insert a carbide tip at the end of a probe, but the tip can become dislodged.
Polyshot covers the carbide probe with a sleeve of beryllium copper. The beryllium conducts heat to the tip of the hot runner, but it never comes into direct contact with the abrasive resin, according to the company.
