Directly Manufacturing Table Tennis Mould by Hybrid Plasma Deposition & Milling

A table tennis mould with good performances of dimensional precision and fine surface roughness was directly manufactured by HPDM (Hybrid Plasma Deposition & Milling), which synthesizes plasma deposition as an additive technology, and milling as a subtractive technique during the processing. Compared with the existing RP methods using high energy density beams, the HPDM method solved the key problems of insufficient dimensional precision and surface quality caused by the step effect, and puts forward a new access to directly manufacture the metal parts and mould with short-process and high quality.
