D-M-E supplying new Round Mate system
D-M-E Co.'s new Round Mate hot-runner system brings hot-runners through a Round Mate mold insert to parts that normally would not justify a complete hot-runner mold.
The self-contained system is available in two, four and six drop units for the 6-inch Round Mate, and in two, four, six and eight drop units for the 8-inch model.
D-M-E supplies the complete system assembled and pre-wired to fit the specific molded part.
D-M-E of Madison Heights, Mich., is a unit of Cincinnati Milacron Inc.

Simulator provides realistic training
Paulson Training Programs Inc. claims its new SimTech-1 injection molding simulation program gives complete updates on the user's progress, changing the process to control changes.
SimTech-1 gives employees realistic training in setup and problem solving.
Unlike systems that merely give a good part-bad part response, Paulson said, its SimTech-1 gives detailed quantitative and visual feedback. At any time, the operator can see the results of five previous cycles and assess progress toward eliminating defects.
``We're building a bridge between process knowledge and realistic molding experience,'' said Craig Paulson, general manager of the Chester, Conn.-based training products company.
The simulator program runs at a fast operating speed, with realistic graphics and sounds.
Users can choose either to select a part to mold or select a molding problem to solve. The first option allows users to pick out a part, set up controls on a control panel and cycle the machine. The cycle runs, then a molded part emerges, complete with defects such as flash, short shots or cosmetic problems. The operator changes parameters until good parts are molded, then works to reach the shortest possible cycle.
The second option lets the user select the level of problem-solving difficulty by listing the level of precision the part requires. The computer screen displays the part and highlights its defect, and the operator must decide how to take corrective action. The computer responds to each action and offers hints.
The operator selects the type of plastic and the size of the molding machine.

Trendelkamp debuts its screen changers
A line of TSK twin-bolt screen changers is available from Josef Trendelkamp Stahl- und Maschinenbau GmbH & Co. KG of Nordwalde, Germany.
During a screen change, the unit hydraulically moves one screen bolt at a time to the changing station. After the screen is changed, resin is allowed to fill the cleaned chamber before it re-enters the production process, preventing air from entering the melt stream, Trendelkamp said.
The screen changer divides the melt into two screen bolts, each of which contains one filtration assembly. The two bolts are contained in a single-piece housing. The melt is reunited after it has passed through the screen packs.
The company is represented by Trendelkamp in Norcross, Ga.

Sheath tubing offers more kink resistance
Putnam Plastics Corp. introduced a line of multilayered sheathing with a range of inside diameters and walls as thin as 0.002 inch.
The company, which is headquartered in Dayville, Conn., said its new sheath tubing offers more kink resistance than conventional tubing and that the product can be bonded with other thermoplastics.

Talc-filled compound aids molding quality
Talc-filled polypropylene overcame quality problems associated with unfilled PP in parts for a blood gas analysis machine.
Berkshire Precision Molding Inc. of Great Barrington, Mass., chose Polifil T-20, a 20 percent talc-filled compound, to injection mold a threaded cap and fluid detector for an undisclosed customer. The compound, supplied by Plastics Group of America, of Woonsocket, R.I., has good impact strength and chemical resistance and holds tight tolerances for these parts.

Firm offers painting service to processors
Injection molders wanting clean equipment have another option.
D.T. Baldwin machine upgrading service of Wildomar, Calif., uses a low-pressure spray to paint equipment in a processor's shop environment, generally taking up to two days per machine.
David Baldwin started the business in 1995 as an offshoot from Humphrey Plastics Machinery Inc., a Wildomar dealer-broker that offers the service as an add-on to buyers of used presses.
Recently, a Baldwin crew cleaned, masked and applied a paint scheme of light gray and deep blue on 17 presses at custom molder Magic Plastics Inc.
``Many customers' knowledge of equipment stops at appearance, and their reactions have been much more than imagined,'' said John Sarno, vice president at Magic.
The Nissei, JSW, Reed, Van Dorn and Tien Fa machines have clamping forces of 75-750 tons and vintages of 1972-91. Magic Plastics employs 95, occupies a 45,000-square-foot facility in Santa Clarita, Calif., and operates around-the-clock seven days.
``We barely missed a beat,'' Sarno said.
Baldwin completed the job over the Labor Day weekend, painting the walls and floor for an additional charge. Other services want to pick the machine up, clean it and put it back, halting a unit's production for two to three weeks or longer, Baldwin said.
``We don't even unhook the machines.''
Although most jobs are in California, Baldwin's crews painted six machines in a Phoenix shop and cleaned up 10 presses in a North Carolina plant and eight in a South Carolina plant.
``We will go anywhere if there are more than five machines,'' he said.
Cost is $600-$5,000 per press, depending on the machine's size.

Primex adds PP sheet to packaging lineup
Primex Plastics Corp. added polypropylene sheet to its medical packaging lineup, the Richmond, Ind., firm announced.
Primex said PP sheet has low specific gravity, good chemical resistance and can be modified with fillers for specific applications. The company makes the sheet, plus high-impact polystyrene and PET medical sheet, in white rooms from virgin resin.

PPC providers lighter PP molding product
PPC Inc. developed a nonhalogenated, flame-retardant polypropylene it claims is up to 30 percent lighter than conventional products.
PPC said its Zeral family of PP compounds is cheaper per volume than other nonhalogenated and halogenated PPs. The Stockerton, Pa., firm supplies Zeral homopolymer and copolymer grades for film, sheet, profiles and injection molding.
