Lines for Automotive Cables and Building Wire

Our extrusion technology has been successfully used for many years to produce cable for the automotive and building industries. The production field ranges from standard machines to customer-specific systems with maximum performance and efficiency.
Whether you increase your productivity with high production speeds or reduce your start-up losses to a minimum with our dynamic, diameter-controlled ramp function or if you detect and separate product errors via the SIEBE Process Control System or reduce them with our automatic color change systems - SIEBE has the economic solution for every application.

Contact us and we will be happy to advise you on the design and conception of your system. 


CORES

SIEBE extrusion lines for automotive cables guarantee that cable manufacturers meet the high quality requirements of the automotive industry, even at the fastest production speeds.
Equipped with the SIEBE Process Control System (SPCS), the following functions ensure maximum production reliability and minimum start-up and color change losses:

  • Hot-cold diameter control with ramp function

FLAT CONDUCTOR

This SIEBE extrusion line is designed for the production of flat conductor cables.
In order to leave the extrusion head as a fixed point in the cable line and to compensate for the thermal expansion that occurs during operation, the entire plasticizing unit is mounted on the machine body so that it can be moved with solid linear guides. The tool changing system enables a quick tool change.

The extruders of the HSP series are built in compact form on a solid welded construction. The motor is located under the cylinder, which not only saves space but also ensures compact power transmission to the gearbox, resulting in pulsation-free output with maximum temperature and pressure uniformity. Careful selection of materials for the screw and cylinder provides good anti-friction properties and minimum wear during operation. Combined with precise temperature control for each heating zone and temperature fluctuations of less than 0.25% of the nominal value, SIEBE extruders guarantee non-destructive plasticizing of the material.
Their high performance is based on the following specially assembled components:

  • Use of high-performance extruders from the HSP series for main and co-extruders
  • Multiple unwinders for variable cable constructions
  • Tool changing system with three tools for quick changeover
  • Caterpillar traction and pusher units for non-destructive transport
  • High-precision measuring devices
  • Horizontal buffer storage
  • Double winder

The equipment of the extrusion line with the various system components, e.g. a co-extruder for strip marking, is so flexible that almost all production-specific special requirements of the customer can be taken into consideration.

Fluorine Cable

Compared to a "conventional" extruder, the fluorine extruder differs only in its specially alloyed surfaces. The very acid-heavy fluoropolymers must be processed with extruders that have a special acid-resistant surface alloy. Conventional materials would only withstand the high degree of acidity for a very short time.
Fluorine extruders are therefore less suitable for processing standard polymers. The focus in material selection is clearly on acid resistance, but not on abrasion resistance.
