A new thermoforming technology from Industrial Design & Engineering Corp. eliminates trim scrap from thin-gauge thermoforming, the company said.
``There's no trim scrap in this process. All the material that goes into this machine is actually used,'' said Ken Redman, Indec president. Redman, who has 20 years of experience in thermoforming and blow molding machinery, founded Indec in 1994.
Indec of Forestdale, Mass., makes the thermoforming machine and supplies a pre-fabricated web, which Redman is calling tape. Indec makes the tape per customer requirements, and the tape must be run on an Indec thermoformer.
Redman is targeting end users — product makers that do their own thermoforming to make packaging — not contract thermoformers.
Indec creates the tape by cutting down a wide web, or roll of thin-gauge plastic sheet, into smaller sizes. The firm converts the material by die cutting, forming holes, printing on graphics, embossing and other processes. The material is wound onto rolls and shipped to end users for forming into blister packs.
Indec's thermoformer specifically was designed to form this tape, at up to 20 cycles a minute. Because the tape is cut to size, there is no trim scrap, Redman said. Instead of pulling the sheet through the machine with pin chains — a method that also causes scrap as the machine bites into the edge of the sheet — the Indec machine uses guide rails.
Highly directed heating also helps eliminate waste. Right before forming, the specific area on the sheet that gets thermoformed is contact-heated. That eliminates heat history in the flanges, which can cause problems with PET sheet, Redman said.
The sheet is indexed through the forming press, then into a slitting section, and on to downstream equipment.
