Plastics News reporter Steve Toloken gathered the following news briefs during NPE 2003, held June 23-27 in Chicago.
Kreyenborg offers two-piston changers
Kreyenborg Industries USA Inc. introduced several models of off-the-shelf, dual-piston screen changers capable of processing up to 3,500 pounds per hour.
The Lawrenceville, Ga., company said the machines are designed to bring the advantages of a continuous screen changer to the lower end of the market, which currently is dominated by slide-plate screen changers.
``The more we drive the price of the two-piston down, the more we'll move volume and take the slide-plate market,'' said President Dana Darley.
Kreyenborg is a subsidiary of Kreyenborg Group in Mnster, Germany.
At NPE, the firm showed the VL-125 model, which processes 1,500 pounds per hour and sells for $24,000. The company is targeting the sheet, film and profile markets that use commodity materials, he said.
The machines are the first mass-produced, continuous, dual-piston machines, he said.
CRG will assemble
PHT screen changers
Auxiliary equipment maker CRG Group plans to begin assembling screen changers under an agreement with Italian manufacturer Plast Hi Tec srl.
CRG, based in Lake Bluff, Ill., will begin making three models of screen changers at its Appleton, Wis., factory within the next nine months, said Carl Gillig, CRG president.
The company will start with manual screen changers, then add hydraulic and dual-piston models, he said. Some key components still will be made at PHT's operations in Ferrera, Italy, but final work will be done in Wisconsin, he said.
Gillig said the work will expand his company's business 30 percent. He said the PHT units integrate well with CRG's existing control package.
Gneuss rotary system
Gneuss Inc. introduced an improved rotary filtration system and an integrated screen changer, pump and filter for processing PET bottle flake.
The Matthews, N.C., company, a unit of Gneuss Kunststofftechnik GmbH in Bad Oeynhausen, Germany, said the rotary system offers 20 percent more filtration area through improved design. The rotary system allows for maintaining the same pressure when a screen is changed, said Monika Gneuss, vice president of sales and marketing for the U.S. unit.
The equipment is designed for high-end applications like foam, she said.
The company also introduced a system that closely connects the screen changer, pump and final filter, saving space and cutting dwell time of the melt to a minimum, she said.
Herbold Meckesheim GmbH introduced a two-in-one granulator/shredder for difficult materials.
HOG shredders can take material that a traditional granulator is not able to handle, and the equipment can be used in wet operations, said Dominic Antico, president of Resource Recycling Systems Inc., a U.S. subsidiary of Herbold.
Resource is based in Smithfield, R.I.
The company has been making the HOG model for about four months and still is testing it to see what markets it can serve best, Antico said.
The company also featured an upgrade of its SMP-series granulators and introduced its HV-series Plastcompactor.
The Plastompactor is designed for converting scrap with poor flow characteristics to agglomerated particles with high bulk density.
Plasmac Ltd. claims
extruder cuts costs
United Kingdom extruder maker Plasmac Ltd. introduced a new recycling extruder it said offers shorter screw lengths and reduced operating costs over previous models.
The XL uses half the power for the same output and has a 12 percent shorter screw length than earlier models, reducing the heat history of the recycled material, said Alan Ward, director of Plasmac, based in Aylesbury, England.
The company has been making the XL for about six months, and sees it replacing its Compact line of extruders, Ward said.
The XL will be the first in a new line of cheaper machines that Plasmac said are more efficient.
