Injection-moulded parts are given a small taper on the sides and in bores, to ease
ejection of the part from the mould. Ceramic parts warp a little during firing.
As-fired ceramic parts have a tolerance of +/- 2% of the dimension or +/- 0.2 mm,
which ever is greater. Closer tolerances are achieved by grinding and lapping. The
table below indicates the tolerances that we can offer. Grinding has to be done
by diamond tools and is a costly operation.

Geometric tolerance includes shape tolerance and position tolerance, which refers to the allowable variation in the shape and position of elements in the drawing. Its label not only points out the controlled element, but also gives the value of the allowable variation, that is, the tolerance value. Features (points, lines, polygons) are controlled by the measured range. The general tolerance of linear dimensions refers to the tolerance that can be guaranteed under the general machining conditions of the workshop!
