Advanced control of on-line gauging system

Pro.Net, a new PC-based controller from NDC Infrared Engineering, combines sophisticated monitoring and control with the latest open-architecture communications technology. It is designed for reliable operation in a processing environment. Pro.Net uses the TCP/IP networking protocol and universal Java programming language to make detailed, up-to-date process data available directly to those who need it, across a secure Intranet.

Pro.Net offers detailed process data from any authorized PC in the organization, and production problems can be solved remotely across the network if necessary. Pro.Net is compatible with many plant automation, statistical analysis, reporting and calculation packages. A single Pro.Net system provides control of up to six scanning frames and 18 precision measurement sensors from the wide NDC Infrared Engineering range. An intuitive touch-screen provides an easy-to-use operator interface to all monitoring and control functions, display options and data storage and reporting functions. Pro.Net supports a wide range of control options and can be set up to control production machinery in many applications.

The Pro.Net PC comes complete with Intel processor, Windows NT and a 21 in. high quality monitor as standard.

Portable analysis kit now controls molding machine

RJG’s DARTPAK Portable Analysis Kit can be hooked up on a portable basis to any standard injection molding machine for collecting data and optionally controlling mold cavity pressure. Molders can collect crucial baseline data from the process before using mold pressure control, then turn the control option on and collect more data. By comparing the two sets of collected data, molders can demonstrate the benefits an in-mold sensor lends toward achieving optimum processing stability.

Features include a light-weight case for easy portability, and a control output which can be a 0-10VDC analog output, a 0-100mVDC analog output, or a set of dry contacts from an internal relay. In the latter case, molders can select a control set point in the unit’s accompanying DARTWin software for Windows, which displays cycle profiles for mold pressure, injection pressure, clamp pressure, screw movement, injection velocity, plastic or oil temperatures, or any of the timed sequence signals or proportional value voltage signals occurring on the machine. Also, a summary table collects data for a ‘snapshot view’ of each cycle.

A ‘tunable’ gate and knockout system all in one

Filling multiple cavities and large, complex parts is easier than ever thanks to the patented Film Gate from Hettinga Technologies, Inc. Available for license, the unique gating device serves two important functions –optimizing resin flow into the cavity and ejecting the part once it is molded. The Film Gate reduces tooling costs, lowers clamp pressures, and decreases molded-in stress.

The Film Gate is ideal for creating large parts and incorporating multiple finishes, such as In-Molded textiles and film. Hettinga’s Film Gate is suitable for all types of plastics, thick/thin walls, and small and large parts. It can be used for flat surfaces, curves and complex contours, and is ideal for glass-filled materials, providing better fibre orientation for greater rigidity and the reduction of knit lines.

Melt spinning extrusion systems ideal for R&D, small production

The new Yellow Jacket Monofilament Fibre Melt Spinning Extrusion Systems, from Wayne Machine and Die Co., are ideal for monofilament and multi-filament synthetic fibres used for medical, textile and aerospace, laboratory research and developmental small production. The lines were designed with the laboratory researcher in mind, who often must make quick multiple experimental runs with a minimum amount of raw material. A wide variety of polymers can be processed including, but not limited to polypropylene, polyester, nylon, acrylics, and polyethylene. These new systems include: 1/4 in. to 11/4 in. Yellow Jacket Extruders with industry-standard feed end driven screws, screen filter pack, optional melt pump, spin head with quick change single or multiple spinnerets, water trough, Godet stations, oven(s) for orientation and annealing, and traverse winder. Custom options are available to suit specific research and production needs.
