General characteristics of Thermoregulated Crossheads Series

This crosshead is developed to process rubber, silicon rubber and silicon and is designed to be thermoregulated by water or oil, in order to guarantee a uniform heat trasmission and consequently an homogeneous temperature.

It is totally made of hardened stainless steel.

This crosshead is designed to work in coextrusion (filling and sheathing) as well as in triple layer mode (filling, sheathing and stripe). It can also work in single layer mode (insulation – filling – sheathing). In case of triple layer mode, the head can be equipped with a skin/stripe ring.

The centering can be:

  1. single from front, by means of die nut;
  2. single from rear by means of tip holder movement (inner layer regulation);
  3. double from front by means of die nut (outer layer regulation) and from rear by means of tip holder movement (inner layer regulation).

The distance between tip and die (gum space) can be regulated by:

  1. an axial die movement from front;
  2. an axial tip holder movement from rear (on request).

Even the die has a dedicated thermoregulated zone, in order to reduce the die drool effect and the lamp/neck on the cable surface. The die thermoregulation allows the operator to act on the cable surface aspect as well.

Treatment/coating to ensure a hardness higher than 1200 HV available, in order to ensure a lower friction coefficient between compound and head, performing the compound flow and ensuring a longer head lifetime: this allows to tackle the increasing of the loaded compound viscosity and the production needs.
