Pa. college center testing 42-inch unit
A new rotational molding endeavor at Pennsylvania College of Technology's broad-based plastics manufacturing center will begin operating a semi-commercial, 42-inch Shuttle PD machine in June. Medkeff-Nye Co. of Akron, Ohio, is making the equipment.
The independent research and development facility aims to focus on technology advancements and industry training. Test equipment in the Williamsport, Pa., site will include a data-collection unit for process monitoring.
ARM panel creating guidelines for texture
An ARM committee of mold makers is establishing standard guidelines for measuring textures in rotational molding.
Previously, a texture "has been specified by the process as opposed to what the texture actually looks like," said committee chairman Sandy Scaccia, president of Norstar Aluminum Molds Inc. of Cedarburg, Wis.
Once completed, the guidelines will eliminate guesswork and variances and assure a designer of achieving a particular texture. "As mold makers, we will hold ourselves accountable," Scaccia said in an interview following a presentation at the ARM conference.
