Latest news from Lima Engineering
This was a project to polyurethane spray coat a CNC machined model board tool.
Model board (Styling Board or Tooling Board) is great for rapid prototyping but can be brittle and easily damaged. Our polyurethane spray coatings provide protection against knocks and wear.
We can spray a variety colours and texture can be smooth or stipple effect.
The beast is bare! The largest vibratory bowl to be relined at Lima has just been stripped of its old lining and blasted ready for inspection. This behemoth Walther Trowal CA1600 will take approx 400 kilo’s of polyurethane to reline. Over the next 2 weeks we will post images of the finished bowl.
Limaenvec reline vibratory bowls from all over Europe. This is a Sweco DM4 just arrived from Belgium.

We are now supplying urethane coated bearings in a wide range of sizes.
Urethane is moulded directly onto a single or double bearing.
Applications include, material handling, conveyor systems, skates, cable guides etc.

For many years we have provided bespoke polyurethane products and components. We are now also offering standard polyurethane products in wide range of sizes.
To start with we will be offering Cylinders (rod), Bar (rectangle – square), Disc and Tubes (tubing).
Many of these items will be in stock but due to the vast range of sizes and hardness, there might be a 4 week lead time.

Two Rosler bowls in this week for refurbishment and relining, R600 and TM22. The first process is to remove the old lining and then grit blast the entire bowl. This serves two purposes: firstly it provides an excellent key for the moulded polyurethane liner to bond and secondly with all the paint removed we can see if there are any stress fractures in the metal.
Our grit blast facility is 6m x 4m x 3m high.
Lima envec manufacture polyurethane sheet which is used in a wide range of industries. Recent projects required polyurethane sheet for the lining of chutes where wear issues needed addressing. 20 mm thick pu sheets were cut, bolted and glued into position, and the steel substrate protected against the abrasive environment.
The project also required a section of steel work lining with spray polyurethane. Spray polyurethane produces a seamless membrane which is idealy suited to the lining of complex or very large fabrications.
Gaskets and seals are also cut from Pu.
Over the last year we have been developing a process of coating foam with polyurethane. We are working with various foam companies to develop methods for coating all types of foam.
Using polyurethane and polyurea spray we are able to give foam substrates increased durability and impact resistance.
Typically foam products are quite fragile when not covered and fall apart very easily. Polyurethane coatings will provide an increased resistance to those stresses caused by bending and deformation.
In the past foam products have typically been covered by stitched pvc covers. These are time consuming to produce and limited to simple shapes. Polyurethane coatings can be sprayed onto any shape and retain intricate detail.

Since developing our bespoke polyurethane (plastic) spray machines we are constantly looking for new market areas that the coating would be suitable. The coating is extremely tough. It offers many advantages over other conventional coating methods. If you an idea for an application and want to discus further please call Simon Latimer on 01282 606300.
Working with more and more clients we were getting asked to polyurethane spray in a wide variety of colours. The conventional way involved mixing a large batch of a particular colour then having to strip and clean the spray machine when another colour was required. This was time consuming and very wasteful. We are in the process of developing a dye dispenser that will change colour at the flick of a switch. Initial trials have proved very successful and we should have a production version ready within the next few weeks.
