ACT debuts six-zone catalytic gas heater
American Catalytic Technologies has introduced a large catalytic gas heater, called the Multi-Zone, that can incorporate as many as six zones for heating sheet during thermoforming.
The Multi-Zone, manufactured by Infra-Red Technologies Inc. of Kansas City, Mo., is the first multiple-zone catalytic heater for thermoforming on the market, President John Critchley said. Branford, Conn.-based ACT, a wholesale and distribution firm, has represented Infra-Red products for seven years, he said.
ACT introduced the Multi-Zone at the SPE Thermoforming Division conference and exhibition, Sept. 19-22 in Nashville, Tenn. ACT has sold a few of the ovens, and will begin testing the first at an undisclosed processor in two to three weeks, he said by telephone Oct. 12.
``Our expertise is integrating this technology into the thermoforming process,'' Critchley said.
The Multi-Zone heater was in development for about a year, he said. The large, tightly profiled heater can have as many as six independent temperature-control zones, each covering an area of 12 inches by 12 inches.
Economic benefits are twofold. First, Multi-Zone can offer thermoformers a cost savings of about 50 percent, compared with buying several individual little heaters, according to Critchley. Second, the oven costs 70-80 percent less to run in some U.S. regions than typical electric elements, he said.
Most of ACT's business is in retrofitting thermoforming machines with new ovens.

ZMD thermoformer allows 5 to 7 cycles
ZMD International Inc. has built a new, fast, chain servo-driven thermoformer that allows five to seven cycles per minute.
The computerized, in-line machine has both a preheating oven and an oven for the final heating cycle. Heaters have top and bottom platens and independent, microprocessor-controlled multiheat zones, ZMD of Long Beach, Calif., said in a news release.
Options include a pneumatic slicing table or an online trim press.

Randcastle presents blown film systems
Randcastle Extrusion Systems Inc. of Cedar Grove, N.J., is selling a new laboratory blown film system, with extruder screw diameters from one-quarter-inch to 11/4 inch.
The equipment makes film in thicknesses of 1-5 mils. The dual-lip air ring enables the top half of the ring to be moved with respect to the bottom half. That changes the amount of air going to each lip.
Randcastle also added a vertical 11/2 inch diameter extruder.

Extruder Empire offers new imaging process
Extruder Empire Plastics Inc. is using a new imaging process to print multicolor graphics on the surface of sheet made from PVC and PVC/ABS alloys.
The process eliminates the need to screen print or offset print images onto sheet and seal it with a protective coating, the company said in a news release. Empire is targeting the Micro Image 2000 sheet at thermoforming applications in commercial airliner, recreational equipment and other potential markets for the company.
Images are saturated or embedded in the sheet at a depth of 7-10 mils.
The Newcomerstown, Ohio, company introduced the imaged product at the SPE Thermoforming Division conference and exhibition, Sept. 19-22 in Nashville, Tenn.

Comet debuts precise color metering unit
Dayton, Ohio-based Comet Automation Systems Inc. has introduced a color metering unit for extrusion, the Color Exact Metering Unit-DC.
The screw-type feeder is designed for precise metering at the feed throat of color concentrates, additives and plastic regrind. It can be connected to the extruder's tachometer control.
