Laval nozzle

Advantage: Realise the mass production of special flow channel design

Remarks: This laval nozzle has gradient diameter shape as shown in the image of cross section. It is difficult to manufacture by machining possibly by EDM, ECM, laser process or MIM. Producing MIM can manufacture various shape nozzles with tight tolerance.

Riverse taper micro structure

Advantage: Metal part and rubber part has to be joined together, by making reverse taper micro pillars such as on the picture, the anchoring effect will strengthen bond strength physically.
Characteristic: Reverser taper shape, which is impossible to realise with other manufacturing technology
