Plastics processors can get a Windows-based computer package that integrates data from machines with business-planning software handling big-picture management functions such as order entry, production scheduling or resin purchasing. Machine monitoring company Nicollet Process Engineering Inc. of Minneapolis and Mascon of Schaumberg, Ill., which makes manufacturing-resource planning software, announced the joint technical effort at Plastics Fair Chicago, held in June in Rosemont, Ill. The announcement follows a year of planning. Both companies exhibited at the show.
Robert Pitner, Nicollet president and chief executive officer, said at the show that process monitoring software collects a huge amount of data about a molding press, but much of it doesn't get used.
``Our concept is that data is very, very valuable for decision-making, but it's got nowhere to go,'' Pitner said.
The companies use relational databases - meaning changes in data in one area of data automatically makes a change in data in another area. For example, say an injection molding cycle begins to stretch out and become longer. That would automatically trigger the scheduling software to stretch out the total time allotted to produce the part.
According to Nicollet Process Engineering and Mascon, a processor that wants to unify business planning and control systems with machine monitoring currently must develop its own custom-made, ``black box'' integration between both systems. But companies want a better system, Pitner said.
Amir Raza, marketing manager of Mascon's Products Division, said most monitoring and control systems still are not compatible with Windows, despite growing demand.
By this fall, several processors will be testing the product, which integrates Mascon's Advanced Integrated Manufacturing Soft-ware, an MRPII product, with Nicollet's PMM plastics machine monitoring. The idea is to create a seamless product that links both companies' software.

Granulator/shredder aimed at big parts
Polymer Systems Inc. of Berlin, Conn., has come up with a piggyback shredder/granulator for regrinding large parts, such as automotive components and big purgings.
The system marks the company's entry into shredders.
Waste parts are first placed into the shredder, which cuts them up, then they drop down to the granulator underneath.

Promax press has new frequency drive
Injection press supplier Pro-max Plastics Machinery Inc. of Compton, Calif., has introduced a machine with a new frequency drive, said to deliver an alternating current-drive motor with a constant speed, to move hydraulic fluid.
Steve Cropp, engineering manager, said the frequency drive can give an energy savings of 5-50 percent. The drive speeds up and slows down the AC drive.

D-M-E Co. of Madison Heights, Mich., has developed a new, compact, portable cavity and hydraulic-pressure monitor and controller, which it showed at Plastics Fair Chicago, held in Rosemont, Ill., in June.
The self-contained injection process controller offers a digital display readout of cavity and hydraulic pressures, including peak pressure during the cycle.
Calibration of pressure sensors and selection of the pressure sensor and ejector pin size are managed from a push button and rotary switch, respectively, according to the company.
A second rotary switch allows for a choice of the type of information to be displayed. A light illuminates when mold pressure reaches setpoint, indicating the the unit's control function is on.
The injection process controller supports both 120 and 240 VAC operations. It functions in a temperature range of 50§-130§ F.
D-M-E develops new monitor/controller
D-M-E also displayed the Cav-Xp 2000 expandable cavity technology from Roehr Tool Corp. of Hudson, Mass., that it distributes. The design of the expandable cavity involves independent flexing segments that are maintained under compression during molding. The segments ex-pand radially away from the part when the mold opens, allowing the part to eject automatically.
The CAV-Xp 2000 will mold parts with outside dimensions of 0.03-3 inches. It can be used in existing molds or in combination with collapsible cores and minicores, according to D-M-E.
D-M-E also has expanded its Smart Series line of control systems with the production of a low-voltage temperature-control system that integrates 240 VAC and 24 VAC zones in one unit.
Problems with reading thermocouples in a multiplexed system are eliminated by the use of isolated thermocouple inputs, with either gounded or ungrounded thermocouples, D-M-E said.
The low-voltage temperature control systems are available in eight-zone and 12-zone formats.
