The following new-product introductions were gathered by Plastics News senior reporter Bill Bregar and assistant managing editor Bill Henson at Plastics Fair Charlotte, held Nov. 12-14 in Charlotte, N.C. Dutch auxiliary equipment maker Movacolor BV has introduced Movacolor 24, billed as a highly accurate volumetric metering machine for injection molding and extrusion.
The horizontally mounted dosing cylinder eliminates surging of material, which Movacolor says is common to standard auger-type meters. The SmartControl controller has instructions in eight languages.
The unit can be used for metering additives such as colorants, powders and foaming agents.
Products made by Movacolor, based in Hoorn, the Netherlands, are distributed in the United States by Romax Inc. of Louisville, Ky.

Van Dorn Demag Corp. kicked off its new productions leading up to NPE 1997, announcing that its newly redesigned HP hydraulic injection molding machines are available.
The 880 HP is the first updated design for the HP Series, which covers midsize hydraulic machines with clamping forces of 275-880 tons. Van Dorn Demag next will offer the new design in a 770-ton press.
The Strongsville, Ohio, machinery company sold the first of the 880-ton machines to Textron Automotive Co.
The press was delivered to the MacDonald Textron molding plant in New Baltimore, Mich., in October.
The biggest change is a much longer mold open stroke (60 inches) and a maximum daylight of 961/2 inches, big enough for the deepest housewares or appliance mold. The company said these specifications typically are found on a much larger-tonnage machine.
The injection unit now is guided on injection carriage guide rods instead of a sled-type carriage.
The clamp unit has enhanced supports that brace the tie bars along the entire length of the strokes. In the pump system, Van Dorn Demag engineers have replaced two separate valves with one three-port valve, improving accuracy.
Van Dorn Demag also has created a new product manager's position for large-tonnage machines.
The company hired Scott Kroeger, who has worked at injection press manufacturers Engel Machinery Inc. and Klockner Ferromatik Desma.

Watlow Electric Manufacturing Co. of St. Louis has redesigned its Wedge-Lok clamp for nozzle heaters.
The clamp is available with a permanently attached clamping strap. The low-profile, 11/2-inch band fits into a 2 1/8-inch die hole that adds only five-eighths inch to the nozzle diameter, according to the company.
Watlow also has created a catalog of stock heaters, sensors and controllers. The 96-page catalog features more than 1,500 products, from nozzle and barrel heaters to temperature sensors and power controllers — most of them available for same-day shipment.

Syscon-RKC of South Bend, Ind., has introduced a new ``D'' series of temperature and pro-cess controllers with an advanced fuzzy logic inference algorithm that the company claims suppresses and eliminates overshoot on start-up or set-point change while responding quickly to process upsets.
The Rex-D100, Rex-D400 and Rex-D900 feature universal inputs and programmable dual alarms for temperature, loop break alarm or heater break alarms. Optional features include a 24 VAC or 24 VDC power supply and auto/manual station capability.
Syscon also has developed, with SpecView LLC of San Ramon, Calif., supervisory software for Windows that detects connected controllers. The SpecView program features a user-definable graphic display and report structure, data logging, trend and bar graphs, alarm monitoring, recipe handling and on-line help.

Depew, N.Y.-based Shuman Plastics Inc. is selling a new formulation of its Dyna-Purge V purging compound for use by injection molders and extruders that process rigid or flexible PVC resins.
Shuman said Dyna-Purge V contains no vinyl, thus remains stable through the normal but narrow processing temperature range for PVC of 320§-400§ F.

Maag Pump Systems of America Inc. of Matthews, N.C., has added a line control system, the MPC 4000, to its MPC series of controllers.
Developed in partnership with Charlotte, N.C.-based Dana Corp., the upgradeable MPC 4000 includes an Intel 486 DX4-100 microprocessor, which can be expanded to the Intel Pentium series processor.

Steel designed for
complex tools, dies
International Mold Steel Inc., headquartered in Erlanger, Ky., introduced a pre-hardened 40 RC steel for molds and dies that the company said is particularly suited for complex, high-precision dies and parts.
The DH2F can be machined as much as 30 percent faster than other pre-hardened H-13 steel, eliminates heat treatments and shows abrasion resistance as much as 50 percent greater than steel of similar hardness, according to International Mold.
