Hallmarking Process

APPLYING THE MARK

Unless specifically instructed by the customer, the Assay Office will determine the most appropriate method by which to apply the mark. Several different techniques are available. It is very important to select the procedure most appropriate for each article. This will depend upon the shape and construction of the item, the quantity to be marked and the size of the hallmark to be applied.

Hand operated or hydraulic presses may be used and large or awkward shaped articles are still "struck" by hand. At the opposite extreme, the latest technology offers laser marking which is particularly suitable for hollow or imported items where customers do not have the opportunity to refinish an article after hallmarking.

When applying the mark by whichever method, it is essential that the article is properly supported to hold it still and to withstand the impact of the punch. 

LASER MARKING

AnchorCert India has invested heavily in the latest technology to enable marks to be applied using laser technology. This is particularly suitable for hollow or imported items where customers do not have the opportunity to finish an article after hallmarking.

There are now two styles of laser mark available: - an outline or incuse mark, and a relief mark which is similar in appearance to a traditional struck mark.

OUTLINE LASER MARK 
Very useful for marking hollow, finished or intricate jewellery products, where a punch mark is undesirable.

RELIEF LASER MARK

Suitable for larger marks on finished or semi-finished products particularly where a display or feature mark is used. It is already popular on money clips, key-rings and silver giftware because it is now possible to produce a feature mark without any bruising or distortion at precisely the required size, position and depth.
