Shamrock Plastics Inc. invested $600,000 in a 9,000-square-foot addition and two machines, after exceeding its 1996 sales expectations.
The Peoria, Ill.-based custom thermoformer began occupying the new space in early April. About 7,500 square feet will be used for receiving and storage space, while the other 1,500 square feet will be used for manufacturing.
A three-station rotary vacuum former, manufactured by Maac Corp. of Itasca, Ill., will be up and running by the end of the month, said Shamrock sales manager Jack Hathaway.
The company added a five-axis computer numerically controlled router in February. Although Shamrock had planned to move the CNC router into the new area, it decided instead to move other production equipment to the addition, he said.
``We've had increased business, mainly an expansion of our existing customers,'' Hathaway said.
With 60 employees, the company had been running three shifts, six days a week. Officials hope to scale back to five days a week with the addition of the new equipment.
Shamrock had expected sales of about $3.5 million last year but saw them rise beyond $4 million. Shamrock makes custom vacuum and pressure formed plastic parts from ABS, polyethylene and polystyrene. It serves the food, automotive, boating, medical, advertising and packaging industries.
The company placed No. 89 in Plastics News' ranking of North American thermoformers, with 1995 sales of $4 million.
