The 2500 Ultra represents a new generation of in-line thermoformers from SencorpWhite, Hyannis, Mass. This form-and-trim system has a larger forming area, longer oven, quick-tool-change system, and increased tonnage on forming and trim presses. It provides both higher output and increased flexibility for short runs. A longer oven with additional heating zones offers better control of sheet temperature, increasing production throughput with polyesters, which have a narrow process window and can be difficult to heat precisely. Better temperature control also makes forming RPET easier. Increased cutting tonnage helps trim hard-to-cut polyesters.
Automatic shut-height adjustment, available on both the forming and trimming presses, cuts tool-change time and eliminates the need for make-ready plates and shims. Standard 7-in. stroke for forming and trimming presses allows companies to form deeper parts.
