Hex washer bolts, headed on Videx rod header ▲

Success at wire 2006 in Düsseldorf, Germany, has seen Extrudex receive a large number of enquiries for extruders and follow-up equipment for the production of miniature cables. This has included several successful sales of mini extrusion systems for medical technology. Due to ever-complex systems in the medical and automation fields, date and power supplies need to be securely provided in the smallest space available. This means conductor diameters in the range of AWG 25- AWG 50 and wall thicknesses in the micron range, for example 20µ. The wire 2006 success for Extrudex ▲

Videx hand feed cold formers

Videx is offering open die cold formers for long fasteners, with 1 or 2 dies up to 200 ton heading. The machines are offered either fully automatic from coil, semi-automatic from magazine or hand fed manually by an operator. The hand feed cold formers are an inexpensive solution for production of small and medium size batches of long parts, headed, collared or extruded. The machines are very efficient for long parts or for parts which require long strokes. The gripper dies are mounted in an independent block which is lifted by a pneumatic cylinder and then slides out of the machine, enabling a change- over in minutes. The stroke is adjusted by an easily accessible nut at the back part of the machine. The machine is designed with a slim body that enables feeding of pre-bent parts either from the front or the side.

Extrudex – keeping rejects to a minimum

required tolerances correspond to these and keeping to them is a must for all processes. Extrudex extruders with screw diameters of 12mm and 15mm have a conveying length of 25D. Minimum melt stopovers prevent excessive demands and reduce any quality loss, such as inclusions or burns. In addition to this, possible rejects are kept to a minimum. Output is between 50 and 3,500gh depending on the material and tools used. The unit is driven by a maintenance-free AC motor. The conveying screw range is designed for standard pellet shapes and can be optimised according to the materials. More than 50% of all enquiries are about fluoric plastics. Extrudex has long had procedural competence in this area. The extruder for this field is corrosion protected in all material carrying areas and equipped with high temperature heating systems. Installation of the extruder can be according to the users’ needs. There are machine stands with horizontal or vertical adjustability for localised use, of a permanent base frame with integrated gear and temperature controls.
