LRM Industries Invents Twin Sheet Direct Thermoforming

| From

ROCKLEDGE, Fla. (SEND2PRESS NEWSWIRE) -- LRM Industries International, Inc., headquartered in Rockledge, Florida, announces the invention of TSD Twin Sheet Direct™; a new innovative production process, extending the product value of its patent-pending STF Sheetless ThermoForming™ technology, which was invented and commercialized by LRM in 2007.

TSD Twin Sheet Direct™ thermoforming uses existing traditional twin sheet thermoforming molds to produce very large dual-layer structural or hollow thermoformed products in a totally automated process. There is one major process difference from existing twin sheet thermoforming: no pre-manufactured thermoplastic sheet is required. The molds are "coated" with molten thermoplastic material directly from extrusion in a profiled lay-down, and then joined to form the product. This means that no ovens are needed, and the process of stretching "softened" thermoplastic sheets inducing stress and thickness non-uniformity is eliminated.

According to Dr. Dale E. Polk, LRM's Chief Technology Officer, "When we developed STF Sheetless ThermoForming™ two years ago, we were surprised to learn that no one had achieved thermoforming using molten plastic from extrusion. This new TSD Twin Sheet Direct™ thermoforming is a logical extension of STF and adds a whole new dimension of product possibilities to our innovative new STF Line."

A wide range of thermoplastic polymers can be used to produce products with TSD Twin Sheet Direct™, and, of course, the process allows on-site, closed loop recycling capability.

Company Information

LRM Industries International, Inc. is a company established to commercialize TPF ThermoPlastic Flowforming™ technology, a radically different and award-winning process technology for producing large, feature-rich, long-fiber reinforced thermoplastic composite parts in one fully automated molding operation. With the TPF ThermoPlastic Flowforming™ and STF Sheetless ThermoForming™ technologies, LRM enables innovative applications and designs in the use of plastics and thermoplastic composites to produce very large unitary structures where, to-date, it has been viewed as cost prohibitive or lacking in strength and structural integrity.
