Willamette Plastics Information

Custom plastic thermo forming (vacuuming forming) and pressure forming designer and supplier. Two methods of plastic production exist: vacuum forming (thermoforming) and pressure forming. Both evacuate air from the sealed space between a heated plastic sheet and a mold to make the sheet conform to the mold. Pressure forming is for parts requiring higher precision and features such as sharp undercuts; to achieve these features, compressed air is added to the operation, from 20 to as much as 150 psi. For fast set-up and production of plastic parts, especially large parts, vacuum forming (thermoforming) or pressure forming with sheet plastics has become the processing method of choice. After approval of part prototype, begin production using the latest equipment: * Solid Works station to receive and create drawings * Vacuum forming machines * Three station rotary (5' x 11') * Pressure former (4' x 8') * 5 axis routers up to 5' x 10'
