New lining for a Walter Trowel fininshing machine
Lima Envec specialise in the relining of metal finishing machines. This post illustrates the quality of a cast polyurethane (Pu) liner and in particular the fit of the dam flap within the work chamber is worthy of note.
This lining is 4o mm thick and a full overhaul of the offload mechanism has been carried out.
Feeder tray coated in polyurethane
Lima Envec manufacture to customer requirements scraper blades and belt scrapers. From tough durable materials pu belt scrapers remove material from the underside of conveyor belts. Lima Envec also manufacture screen decks and wire mesh coated with spray Pu.
The Limathane range of spray polyurethane coatings has been specifically designed for the one off items or complex shapes, where tooling prices are prohibitive.
These 100% elastomer coatings offer outstanding protection against abrasion and corrosion and for sound reduction applications.
Remarkably tough and hardwearing, these abrasion resistant coatings are available in a choice of standard colours and can be applied to a range of substrates, such as steel, aluminium, GRP, wood and even concrete.
Features include:
Lima Envec coat hoppers and feeders in polyurethane. Where wear and noise are issues polyurethane spray provides a tough durable lining. There is no requirement for a mould tool as the material is spray applied and built up in many layers. The resulting coating is a seemles lining with no limit on thickness. A range of hardness and colours are available.
Foam roof coated in polyurethane.
Lima envec provide polyurethane spray coating to industry. Extremely hard wearing linings have many uses and the service is particularly useful where large and complex shapes require a tough durable membrane.
Recent projects include the lining of a tank which is used for radiusing springs. The coating protecting the steel substrate from the abrasive enviroment.
Bowl feeders are coated with polyurethane to aid drive, reduce noise, and to extend the life of the work bowl. 3 day typical turnaround time so minimise disruption to production.Worn bowl feeder repaired as part of the service. A range of colours are available. Painting of the outside of the bowl is part of the service.bowlfeeders

3 metre long trough with a polyurethane lining
Customer required a relining of a long through finisher in a cast polyurethane. Previously relined with spray Pu customer was seeking improved life from the lining so a moulded polyurethane material was selected.

FM 3 with a cast polyurethane reline
Large polyurethane bend stiffeners manufactured from a polyether system are ideally suited to a marine environment. The 70 kg moulding is produced in a single pour to ensure no knit lines. Piggy back saddles are also a speciality product manufactured by Lima Envec.

This post describes the relining of a William Boulton FM 10 . The process involves removing the old worn lining, grit blasting the work chamber back to base metal.
Then a suitable steel mould tool is suspended inside the work bowl and liquid polyurethane poured into the void between the steel work bowl and the mould tool. The next stage is to remove the mould tool and fit any doors or drains. Finally the outside of the FM 10 is painted to meet customer specification.
