A cleaning piston for a mixing head of a reaction moulding machine, said cleaning piston comprising:
- a main part having a cylindrical casing region;
- and
- a clearing part made of a non-polar material and having a geometry reflective of a sharp-edged contour so as to remove residual material adhering during operation to a channel of the mixing head.
A mixing head for a reaction moulding machine, comprising:
- a mixing chamber;
- a control piston arranged in the mixing chamber for regulating a component flow;
- a discharge channel;
- and
- a cleaning piston inserted into the discharge channel in at least one cleaning state, said cleaning piston including a main part having a cylindrical casing region, and a clearing part made of a non-polar material and having a geometry reflective of a sharp-edged contour so as to remove residual material adhering during operation to a channel of the mixing head.
A reaction moulding machine, comprising a mixing head, said mixing head including a mixing chamber, a control piston arranged in the mixing chamber for regulating a component flow, a discharge channel, and a cleaning piston inserted into the discharge channel in at least one cleaning state, said cleaning piston including a main part having a cylindrical casing region, and a clearing part made of a non-polar material and having a geometry reflective of a sharp-edged contour so as to remove residual material adhering during operation to a channel of the mixing head.
A discharge pipe for a mixing head, said discharge pipe constructed for attachment onto a housing of the mixing head such as to form a section of a discharge channel, said discharge pipe being made at least partly of a non-polar material.
