PU foaming equipment for shoe soles
Match shot weight, dispensing and electrically heated stations to your sole range.
List the smallest and largest shots across your sole range. Include the cavity count, material formulation and desired output per shift. If you already make the part, describe short shots, flash or release problems by mould. Review dispensing, mould condition and heating together before specifying the line.
