A new crosshead — the CV 500 Series from Guill — now enables continuous vulcanization of rubber with much better flow distribution and improved temperature control over competitive products in the market today.
This new crosshead enables rubber product manufacturers to deliver cables as well as individual wire in multilayers of up to 6 inches (152.4 mm) in diameter, while at the same time reducing waste and costs in the manufacturing process.
The CV 500 Series is a fortified crosshead design particularly well-suited to meet the greater strength and tolerances required in the manufacture of wire and cable for electric utility and other high-voltage applications.
Our new CV 500 Series delivers to the marketplace the higher-performance extrusion capability that electric utility customers have been demanding, said Bill Conley, Guill’s Technical Sales Manager. Our design and engineering process makes the difference.
Flow Design Testing & Analysis are Key:
Key to the performance of the CV 500 Series is the rigorous flow design testing and analysis that enables the production of the more-difficult rubber applications with a high level of product consistency throughout, resulting in adherence to the precise tolerances and thinner walls required in these applications. This testing and analysis process encompasses such parameters as flow, pressure, heat and wall thickness of the particular product to be extruded.
Even Heat for Better Flow:
Guill advanced engineering is built into the new crosshead. This includes balanced, even heat for better flow, made possible by an integrated water or oil cooling system. With the cooling system the appropriate processing temperature for the rubber in the crosshead is maintained — within one degree of the set point. By having the water or oil-cooling capability the new crosshead eliminates the potential for scorching of the rubber extrusion. The high-tolerance extrusion process made possible by the new crosshead results in reduced material waste, while generating significant cost savings for our customers, Conley emphasizes.
Multilayer Extrusion Capability:
Particularly important for today’s high-voltage cable for the power industry is the new tooling’s capability to produce multilayer extrusions. Unlike tandem extrusion, multilayer extrusion prevents contamination and ensures greater adhesion. We are receiving more and more requests from utilities for multilayer capability, especially for triple-layer cable, adds Conley. As part of the new CV design, Guill’s multiport feed system and the configuration of the flow splitter determined through flow testing and analysis, enable customization for the precise multilayer requirements of each customer’s specific needs.
Other Important Guill Technologies Built Into the Crosshead
The new CV 500 Series encompasses many of the other high-technology capabilities featured in various Guill tooling.
- Fixed center or adjustable center capabilities. Most multilayer applications use an adjustable center configuration.
- Quick tooling change as short as 15 minutes for less down time.
- Adjustable gum space for more control of product size.
- SealRight System leak-free design.
The new CV 500 Series crosshead is competitively priced in the marketplace.
Guill Tool received ISO certification in 1995 — the first major extrusion tooling company worldwide to meet these international quality standards. The company has long been recognized as one of the leading established designers and manufacturers of custom extrusion tooling for all types of applications including: wire, cable, fiber optics, medical tube, wood composites, automotive tube, plastics compounding, custom applications, rubber, profile, industrial pipe, hose & tube, blow molding, food and packaging.
The company also encourages and provides education and training for the extrusion industry with plastic and aluminum model heads, fully illustrated operating manuals for step-by-step assembly and disassembly, training videotapes, as well as classes on the care and cleaning of extrusion tooling.
Founded in Rhode Island in 1962 by A. Roger Guillemette, the company was established as a job shop supplying tips, dies, crossheads and replacement parts to the wire and cable, plastics and rubber industries in New England and eventually across the U.S. and Canada.
