Portable wire drawing oil centrifuging machine

CbS Technologies, India, has developed a 100% consumable-free and maintenance expense-free portable wire drawing oil centrifuging machine, specifically for wire drawing application. The company claims that the machine offers the following advantages: increases die life to more than double; ensures the maximum speed of the wire drawing oil; helps production of bright finished wire; reduces consumption of lubricant; helps recovery of 0.5% to 1% of the material

from the lubricant; repeat pump failures are avoided; and there is no chocking of oil lines.

The machine has a 10kg material holding capacity, and can be cleaned in two to five minutes.

PTFE films and tapes DeWAL Industries, USA, supplies high-performance PTFE films and tapes to the wire and cable industry. The company’s skived PTFE is used for its high temperature resistance, dielectric strength and low friction. Virgin or conductive, and as thin as 0.013mm, it is often used in aerospace, power and high flex cable applications. DeWAL’s unsintered PTFE is used primarily as insulation and outer jacketing for wire and cable at temperatures up to 246°C, from 0.038mm to 0.508mm, and with a density of 1.5g/cc. The company has developed a complete line of vibrant, RoHS-compliant colours, and can add other fillers to meet the requirements of highly engineered wire and cable. The company has also developed technology to manufacture high tensile, low density film – as low as 0.4g/cc. These films are used to wrap primary wires in high flex cable, and other products in this family were developed to meet demanding coaxial cable applications, where low signal loss is critical. DeWAL uses a proprietary process to laminate its fluoropolymer films with dissimilar materials – often elastomers or melt processable fluoropolymers. All DeWAL slit film and laminated products can be flat pad packaged and, depending on dimensions, some skived, unsintered and low density PTFE can be traverse packaged. Pyramid packaging is also used for some skived film and narrow films. DeWAL Industries, Inc – USA Fax : +1 401 783 6780
