High efficiency and process reliability with polished moulds

Precision bulk manufacturing: Screw caps for bottles

recent pressrelease next pressrelease

(PresseBox) - Plastic screw caps are bulk items generally produced by continuous compression or injection mould-ing. Their geometry has to be so perfect that they effortlessly form a leak proof seal around the top of drinks bottles. Screw caps are also used for medicines, child-safe cleaning products, and so on.

To produce them cost-effectively you need to keep rejects to a minimum. And that?s where high-quality precision moulds make all the difference, because the better the quality, accuracy and ser-vice life of the mould, the more efficient your mass production.

The special moulds used for screw caps are usually turned from steel and then milled or injection moulded. In one mechanical post-processing stage (or two depending on the application), the mould is smoothed and polished so that the plastic caps produced on it will separate without sticking or residues, and without affecting the cap geometry. So the smoother the surface, the longer the mould provides top performance.

STREAM FINISHING + PULSE FINISHING =

superb surface quality (Ra < 0.1 ?m) in seconds!

Pulse finishing, OTEC?s stream finishing innovation, has remained the fastest mass finishing pro-cess on the market ever since it was launched in 2013. With average process times of 60 seconds, it?s (literally!) rapidly putting conventional techniques in the shade.

The process obtains uniform results even on complex workpieces like moulds for screw caps, be-cause it?s highly effective at using very small grinding bodies.
