We repair and manufacture many different rollers for a diverse range of business ranging from printing to water treatment.
Some of the markets in which we operate in are:
There is a certain process that our skilled workforce go through every time a roller is brought in.
After the first communication with the customer, we will organise collection, either with our own lorry or via courier. We strive to time collections so that they are convenient for the customer and at a time that will cause minimal disruption to the customers activity.
On arrival at Arolco the roller core is examined for wear, the customer is informed of any repairs required . At this stage the finished specification is agreed (A spec sheet is always compulsory) and with everything confirmed by the customer the roller will progress to the next stage.
Once the roller is repaired, inspected and is deemed satisfactory, we will proceed to stripping all material off, to ascertain that all of the material is gone and there is a good surface for the new covering, the roller is then taken to our shot blasting facility.
After shot blasting the roller core, it’s then degreased with a degreasing agent, depending on what material the roller is going to be recovered with, we then apply a categorical bonding agent.
If the roller is to be covered with rubber it is taken to our department where the specific type of rubber is selected, as in what shore hardness it requires to be, if it is a food grade rubber or if it is a roller that requires to stand higher temperatures. Once the raw material has been applied the roller is then taken to our specialist oven (autoclave) for a specific duration according to the material.
(The process leading up to the re-covering is identically tantamount for both rubber and polyurethane.)
Polyurethane rollers are then taken to our polyurethane casting department, where again the designations of the material has already been established and prepared. The roller is then placed in a custom mould where the polyurethane is then cast, once the roller is cast it takes 48 hours to cure.
The post-covering process again is the same regardless to the material. The recovered roller is then taken to our rotary grinder and ground to the desired diameter and specific surface finish.
The last stage of the roller recovering/manufacturing is the type of surface the customer needs, patterns can be ground into the surface of the roller to the desired specifications, and a grit can be applied to provide additional grip.
The process laid out above is the same for wheels.
Metal rollers and wheels will not require recovering with Rubber or Polyurethane, but the process of inspection, repair and manufacturing is still the same and held to the same standards.
We can re-coat Chrome, Teflon, Rylson, Anolux, Anodised, and Chemical Black
Sometimes rollers or wheels are beyond repairing or recovering, in the interest of providing the best service possible we will advise the customer as to their best course of action which in some situations is not rehabilitating a done roller, but replacing with an new one. Straight away we can commission a new build, done to the customers exact specifications, we can even alter the design of the roller if there is a way of the roller performing better for the customer, i.e. finished diameter or a different material.
