It is possible to achieve very tight tolerances through extremely precise moulding tools and specialised machining.
\nHowever, it is important to bear in mind that the tighter the tolerance, the higher the cost. You should therefore avoid setting tight tolerances unnecessarily.
\nAlways consult us regarding the desired function so that we can offer the most cost-effective solution.
\nDimensional accuracy for polyurethane<\/a> differs from that of metal in two main respects: <\/p>\n

    \n
  1. Elasticity
    \nPolyurethane can deform 100 times more than metal under normal loads.<\/li>\n
  2. Thermal expansion
    \nAs polyurethane has a thermal expansion coefficient 10 times higher than that of metal, its dimensions are highly dependent on temperature.
    \nA component measuring 1000 mm at room temperature will measure 1010 mm at +60\u00b0C.<\/li>\n<\/ol>\n
