YDTech® MANUFACTURER of precision dowel pins(stainless chrome)steel metal brass or WC, Supplier of hardened dowel pins in china.
the dowel pins are ground cylindrical pins primarily manufactured for precise locating devices in machinery and assemblies. Steel dowel pins are machined to tight tolerances with the DIN and ISO standard pins being m6 on the diameter. the corresponding holes are usually reamed to allow for a press fit, clearance fit or transition fit.
we carefully consider the dowel pins material to be used as well as the dowel destination. We take into account the ductility of the destination hole and the ductility of the dowel pins material being used to manufacture the machined parts with accurate dimensions.
regarding size and precision, we manufactures precision dowel pins to exacting tolerances. We can produce dowel pins to a tolerance of +/-0.0002 utilizing stainless steel, tool steel, brass, or aluminum.
when designing engineered components, dowel holes are often used as reference points to control positioning alignment to attain repeatable assembly quality. When dowel pins are pressed into blind holes it is recommended that dowels with ‘air release flats’ are used to allow displacement of air preventing damage to the work piece or the ejection of the dowel.
