Frankfort, Illinois - Industrial polyurethane roll fabricator FKM-USA has announced a new rotary casting process, "based upon the application of highly reactive multiple-part urethanes directly onto a rotating roll core to create a solid roll cover in a matter of minutes," the company said in a recent statement.
FKM said that the new process will eliminate the need for conventional poured moulds and a secondary curing process meaning that, "rotary cast rolls can be delivered in days not weeks."
The new process, the company claim, is much more flexible than standard mould-based technology as it can cast different types of materials onto any rotational-symmetrical body but still retains tolerances and hardness.
FKM went on to say that, unlike the irregularities that can occur in the polyurethane when using mould-cast rolls, the new process holds hardness uniformity across the roll, to produce a roll that typically has better mechanical properties.
The rotary casting machine itself was designed and built by the company.
"With this machine, we've been able to cast rolls in minutes," said FKM general manager Jim Rusczyk. "This capability will benefit our customers as well as opening the door to new markets for us."
