Before plating

Two methods are used. Heat treating and shot blasting. Both may be used in combination.

If required the material can be heated in a large gas or electric powered oven for a set time. This is usually only required for very hard steels. (this is a rare requirement)

Most hard steels are pre-treated by shot blasting the surface immediately prior to plating.

Post plating

When an item is chrome plated, gas is trapped in the plating. If this is not released in a controlled manner, problems may occur when the item is used. Such a problem can occur with a roller used in the manufacture of plastic sheet, as the sheet is passed over the roll, the gas escapes causing small bubbles or holes to appear in the product.

These gases can be removed by heat treating in an oven immediately after removal from the plating vat.
