Swiss Competence Cluster

Erocarb SA In addition to its own 45 years of experience, Erocarb as part of the Swiss Competence Cluster benefits from a network of knowledge and expertise with other players in the wire and cable industry. This strengthens the presence of Swiss companies in the competitive sector, and contributes to enhancing the company’s wide range of standard and customised solutions for plastic extrusion. Erocarb states that its crossheads, tooling and accessories are recognised for their durability and precision. The company adapts to customers’ specific requirements, and develops unique solutions. Flat-ribbon-cable crossheads are one example of how Erocarb has optimised and improved its products to meet the demands of the plastic extrusion world. Its latest generation of flat ribbon crossheads abandon the classical design, which was prone to leakage, concentricity issues and difficult main- tenance, in favour of simplicity and functionality. The new crossheads

consist of a “plate/sandwich” design, which enables better joint integrity between all individual components, as well as increased user-friendliness and a more reliable and robust piece of equipment. This design also allows a reduction in manufacturing complexity.

Flat-ribbon-cable crosshead

concept remains applicable for various applications throughout the cable industry. Erocarb offers various centring solutions, including the rear ball-centring option, which has been part of its equipment range for more than 30 years. The rear centring solutions offer variants including both manual and fixed centring configurations, which can be switched/selected “on the go”. This is optionally available for most of the standard/series crossheads ranging from 4 to 80mm sizes. As a crosshead and extrusion equipment manufacturer and developer, Erocarb also offers customer tailored and product-adapted centring solutions. Erocarb SA www.erocarb.ch

They are available with electrical heating, as well as liquid thermos-regulation. Additional tailor made solutions to suit the customer and product specifications can be delivered. Rear ball-centring, while an old concept, has been gaining popularity in recent years. It had been almost completely replaced by die-centring solutions in the past 10-15 years, to the point of being considered obsolete. However, the concept was not abandoned by Erocarb, which continued to develop the design. The increased demand shows that the covers product
