Limaenvec have manufactured tooling suiatable for the relining of a Walther Trowel CV505 metal finishing machine.

The tooling produces the typical wedge shaped profile required to generate mass polising in the hump area. Traditionaly a rubber or spray applied lining was the only alternative to a factory reline.

In order to offer a competitve alternative a mould was required, and with a typical 5 day turnaround Lima Envec offer a cost effective alternative.

Polyurethane Lining (Pu) of a Blasting Table

A customer required the manufacture of a blasting table covered with abrasion resistant polyurethane. The picture shows the 1.3 metre diameter steel plate lined with 25mm thick poly.

The holes are for letting the shot fall through and were moulded rather than drilled. This table was manufactured for a Pangbourne automatic shot blasting machine.
