Shamrock Plastics Inc. has added a new high-pressure thermoforming machine and is finding more work for parts that have the look of being injection molded.
``We're finding more and more interest in high-pressure forming,'' said Mike Wilkinson, executive vice president of Peoria-based Shamrock.
The firm boosted its abilities, adding a Maac three-station rotary high-pressure machine.
``It gives us the fine detail that injection molding does,'' Wilkinson said.
The process allows for multiple texture or smooth areas. The Maac is the firm's fifth thermoforming machine.
Shamrock customers include makers of off-road, building, food, environmental, sports and medical products. The company also makes a proprietary product called a Lamplighter for holiday decorations. The item fits over outside lights and comes in designs like a pumpkin or a snowman.
Shamrock's 38,000-square-foot plant in Peoria employs about 25 full-time and 12 temporary workers, he said. Employees work four 10-hour days on two different shifts Monday through Thursday.
``It's something that makes sense. Now instead of missing work for a doctor, dentist or lawyer's appointment, they can go Fridays,'' Wilkinson said.
The schedule has worked well for about five years and is a selling point for recruiting employees. The firm also saves utility costs by being shut down for one more day, he said.
