Everything your finish depends on

A good finish needs the right machine, the right media and the right process, and it needs the machine to keep running. We handle all four.

The media matters as much as the machine

The shape, size and material of the media decide how fast parts finish and how they look. We help you choose the right one for your parts, and keep you supplied.

Extend the life of your finishing machines

Most worn machines don't need replacing. We recondition vibratory bowls and troughs, reline them in PU, and replace springs, PU bushes, flopper assemblies and motors. We do this for STS machines and for machines from other makers.

Frequently asked questions

See all questions
Which machine size do I need?

It depends on the size of your parts and how many you need to finish per day. Our standard vibratory machines run from 40 to 900 litres, separation machines up to 1,200 litres, and we build other sizes to order. Send us your part details or a sample and we'll recommend a size.

Can you trial my parts before I buy?

Yes. Send us a few samples with the finish you need. We test media, compound and cycle time and send you the results.

Can you repair or reline a machine you didn't build?

Yes. We reline, repair and service vibratory and centrifugal machines from other makers as well as our own.

Which media should I use?

It depends on the material and the finish. Ceramic media is used for fast deburring and descaling of steel parts, plastic media for aluminium, brass and soft metals, porcelain for fine finishing, steel media for burnishing, and drying media to dry parts after finishing. We'll recommend the right type, shape and size for your parts.
