DIAMOND non-stick ceramic coating system has been specially developed for use as a sole plate for domestic steam irons.

DIAMOND is a double layer system that utilises the latest nano-technology thermally bonding the non-stick ceramic coating to the aluminium ensuring the best performance from the metal and coating. These two layers in combination offer the unique blend of smooth glide and exceptional wear resistance.

When you consider the many benefits for both consumer and manufacturer the decision to go with DIAMOND is a valuable and powerful addition to your product offering.

technology centre

Technology is at the core of the development of DIAMOND.

Working in close partnership with suppliers and customers, we continually strive for and test the best materials & processes to deliver the unique DIAMOND specification.

our testing centre

The development of DIAMOND non-stick ceramic coating for iron sole plates has been the result of technologically advanced coatings applied to precision rolled metal by modern process techniques.

Every aspect of the specification has been considered from the selection of the metal and the adhesion of the coating to the glide and durability of the finished surface.

Robust process controls & test procedures measure the coating thickness, thermal performance, abrasion resistance and the co-effiecient of friction that provides product excellence time after time
