New extrusion film line technology to AAPPI

Machine is a big bonus for RG The purchase of a new swivel bending machine will allow UK company RG Attachments to form a variety of shapes from large sheet metal.

Wayne Machine and Die Company has designed, built and sold a combination 5-layer yellow jacket laboratory blown and cast film line to the Advanced and Applied Polymer Processing Institute in Danville, Virginia. This system is based upon new Yellow Jacket die technology that is capable of producing 5-layer blown and cast plastic film in A-B-C-B-A and other configurations. The line can process polyolefins such as LDPE, LLDPE, and HDPE, barrier materials such as EVOH, and adhesives for tie layer applications. It is ideal for rapid development of multi-layer structures for subsequent testing, while using small amounts of raw material, utilising 5-Layer blown film stack type die and a 5-Layer feedblock and cast film die. The line consists of three 1" 24:1 yellow jacket extruders, dies, blown film takeoff, cast film takeoff and torque controlled winder. The new line is capable of up to 12" layflat blown film and 8" wide cast film. Full instrumentation, including digital auto-tune temperature controls and melt pressure indicators are part of each extruder. The line includes a PC-based data acquisition system that interfaces to each extruder control panel and to record process parameters for statistical analysis, create trending plots and perform recipe storage. The Advanced and Applied Polymer Processing Institute is a full-service polymer processing and research centre.

This task had previously been unavailable for the Leicester- based company who will now find the machine especially useful in the primary stages of Tapeformer production, whereby large metal sheets need to be chopped and formed into smaller, more manageable pieces. The new purchase will allow a higher quality of Tapeformer to be produced, especially for larger cable sizes. RG have been producing Tapeformers for more than 25 years, and they are used by cable manufacturers to fold a variety of insulating material around cable cores before entering the final jacketing stage.

The Tapeformer is positioned just before the extruder head and guarantees precision folds. With an extensive selection of models and folding profiles the Tapeformer is manufactured to your exact requirements. They can be used with many insulating tapes including Mylar, paper and metalised foils and can insulate a wide range of cables including LAN, power, telephone, communication and automotive cable.

Fast wire processing North America OMCG, Inc specialises in machinery for wire and metal strip processing. The company’s CNC-61 multi axis fast wire bender is used for forming wire

from 1mm to 7mm, and can perform 22 flat bends in 7.8 seconds, or eight 3D bends in 7 seconds. The system features easy programming for the input of wire parameters, and allows two to four different bend radii. Options include chamfering and grooving, with parts made in sequence using the position unload manipulator to place them in fixture for assembly, welding or inspection. The machine can process strip, flat or square wire, and if holes are required, a press head can be added. OMCG’s range of CNC machines can handle wire up to 5/8" diameter, and for higher production requirements the company can also supply slide machines. OMCG – USA Fax : +1 203 576 0239
