Rexam acquires Ritemp license

Rexam Mold Mfg. (London, UK), a designer and manufacturer of multicavity injection molds for the consumer packaging, beverage, personal care, healthcare, and food markets, has integrated Ritemp mold cooling technology into some of its engineering processes. Rexam recently partnered with SWM & Assoc. (exclusive representative in the Americas for Ritemp) to identify processing gains and then moved to acquire a development license. SWM Chicago, headed by Terry Schwenk, works directly with tool shops and molders to optimize the entire molding process by reducing production time and operational costs through select technologies like Ritemp.

Wayne Grassel, business unit manager for Rexam, says, “Three things characterize Rexam: leadership in industry, commitment to innovation, and passion to deliver exceptional value. With the recent purchase of a Ritemp mold cooling technology license, Rexam can continue to push the envelope of moldbuilding technology and deliver exceptional value to our customers.”

The development license allows Rexam to provide prototype development tooling using the cooling technology with no further license cost during the mold development.

Ritemp’s patented technology simplifies the design and manufacturing of mold cooling by replacing gun-drilled waterlines with a cooling chamber or water pocket that envelops mold surfaces. The chamber ensures even heat distribution without the engineering compromise often associated with gun drilling. Using heat exchangers, evaporative cooling condenses the liquid, which in turn is recycled throughout the sealed chamber.

The turbulent flow of the water reduces any buildup of sludge within the chamber that might impede mold cooling. To reduce or eliminate corrosion issues, air is removed from the cooling chamber prior to production. The Ritemp mold temperature control automatically senses and adjusts water flow to regulate heat levels.

Ritemp mold cooling technology is suitable for a wide range of applications including packaging, caps and closures, medical devices, technical, and automotive, and has demonstrated productivity increases, including cycle time reductions of 20-50%, according to SWM.—[email protected]
