Plastics News staff reporters Sarah S. Smith and Frank Esposito gathered the following items at Plastics USA 98, held Oct. 6-8 in Chicago.
Trans Tech develops pad-printing machine
Trans Tech America Inc. introduced the Duoseal, a new concept for a single- or two-color pad-printing machine, at Plastics USA in Chicago.
The unit uses two transfer pads mounted to a vertical tower, which rotates 90 degrees alternately in clockwise and counterclockwise directions. That makes it possible for the machine to print two colors with only one stationary holding fixture.
The design also allows a processor to print images on two different levels of the same part, using two independently controlled pneumatic pad cylinders. The machine is mounted to a free-standing base. The pad tower's rotating motion is provided by a mechanically operated index table.
The Duoseal features a print image as large as 80 millimeters in diameter and speeds as fast as 800-1,000 cycles per hour.
Trans Tech, based in Carol Stream, Ill., specializes in pad-printing equipment, accessories and related supplies. It is a unit of Illinois Tool Works Co. of Glenview, Ill.
Albis adds BASF HIPS to its distributorship
Albis North America, a Rosenberg, Texas-based engineering resins distributor and compounder, has broadened its distribution presence in commodity plastics by adding BASF Corp.'s high-impact and crystal polystyrene resins to its product mix.
Albis first ventured into the commodities realm last year when it struck a deal to distribute polypropylene for Epsilon Products of Marcus Hook, Pa.
PP was a difficult sell for Albis at first, said regional sales manager John Krainz, but it eventually led to a lot of good leads because of the firm's existing presence in the engineering resins market.
``We were already selling to a lot of engineering resin accounts so it was a good fit,'' Krainz said at Plastics USA.
In addition to Mount Olive, N.J.-based BASF, Albis distributes for Bayer Corp. of Pittsburgh and Eastman Chemical Co. of Kingsport, Tenn. Its most recent addition is thermoplastic elastomer compounder Alphagary Corp. of Leominster, Mass.
Albis' compounding lineup includes ABS, PS, PP, nylon and polycarbonate.
Cold Jet Inc. offering new cleaning systems
Cold Jet Inc. has launched two new cleaning systems for blow molding and injection molding equipment used to make PET and high density polyethylene bottles.
Cold Jet, a maker of dry-ice blasting equipment in Loveland, Ohio, claims its cleaning systems can reduce the amount of daily mold cleaning time by 20 percent by cleaning molds while they're still hot and in the press.
The systems also feature micro-nozzles with 45-degree and 90-degree bends, which can clean the backsides of blow molds and deep-cavity injection molds, tasks that previously could be done only by hand.
Cold Jet officials said the new systems can eliminate clouding that can occur on the ribbing of PET bottles and the orange-peel effect that residue buildup can cause on HDPE bottles.
PCT's PMS controller easy to trouble-shoot
The new PMS hot-runner temperature controller from Polymer Cleaning Technology Inc. boasts ease of operation.
The new model is part of the HRX series. It offers as many as 12 zones of temperature control, and PCT claims it is the easiest of any comparable unit to program and trouble-shoot.
The unit measures 14 inches by 14 inches by 6 inches — half the size of competitive-brand models, said Belle Mead, N.J.-based PCT. It features wiring diagnostics typically found on more expensive controllers and can store 12 complete setups by name or number.
