Polyurethane and Rubber product projects
Lima Envec specialise in custom pu moulding. A client required a one off blasting table lining with polyurethane. The project involved producing tooling, and a pu lining to withstand the blasting environment. In conjunction with the client Lima produced a stainless steel table with a Polyurethane lining.
The picture describes,
Lima Envec won the order to line 8 off half tanks. The tanks are part of a large washing plant used to separate copper from other materials. The tanks were coated with a 4mm thick lining to protect against wear and corrosion.
The tanks in the 3 stages, new, blasted, and finished.
In addition to the tanks a large scroll and flights were coated.
Customer required the inside of a large wet back booth which was leaking water lining with polyurea. The unit was too large to remove from site so Lima envec were contracted to carry out the works on site.
Picture of the internals of the tank prior to lining. The internals were scarified and sanded back to base metal. Any corroded metal removed.
The substrate then subjected to a chemical bonding agent and sprayed with Polyurea spray. The new 6 mm thick polyurea lining seals all the pin holes and forms a chemical resistant waterproof barrier.
This picture shows the internals of the tank during the lining process. The new membrane following the contours of the internals if the tank. The polyurea material is fast setting, typically touch dry in 3 seconds.
This picture illustrates the final coating. A seamless water proof chemically resistant lining. The works were carried out over an 8 hour shift and the tank put back in service the same day.

Including the manufacture of stainless steel wear rings.
A customer required a Polyurethane moulding of a tree seat. Lima Envec designed tooling from a concept idea and produced 6 of PU mouldings in 6 different colours. The seats are located in Cockermouth Cumbria .

Customer required 3 powder grinding machines lining with polyurethane. Lima manufactured suitable tooling and completed the works within 3 weeks.
