Laser marking at Sheffield Assay Office is an area of ongoing development which has opened up some interesting and innovative applications for this process.
Laser marking is widely used for marking traditional, standard hallmarks onto precious metal but it also an ideal process for clearly and accurately marking a range of logos, signatures and serial numbers for decorative, promotional or engineering and industrial purposes. The Sheffield Assay Office Laser Development Department has the knowledge, skills and laser equipment to engrave, cut and mark precious and non-precious metal and offers a comprehensive service which is used by a range of clients in many different businesses and industries.
Benefits of Laser Marking
- Laser marking is an etching process, therefore laser marking does not cause bruising or distortion and setting back of metal is not required.
- It is possible to mark both flat and slightly curved surfaces.
- The process is ideal for marking hollow or thin articles, flat and curved surfaces and when minimum finishing of an item is required.
- Laser marking avoids the use of labels, presenting a more finished, refined design.
- The Laser Development Department can produce a skeletal/outline laser mark or a deep relief/3D laser mark.
- A skeletal mark is often useful in hallmarking for hollow, semi-finished or intricate jewellery products where a punch mark may be undesirable.
- A deep relief or 3D laser mark is suitable for larger marks on finished or semi- finished products particularly where a display or feature mark is used as it resembles a struck (These marks can be seen on a number of items such as key-rings, photo frames or silver gift ware.) It is possible to create a mark at precisely the required size and position.
- The deep laser 3D laser mark is long lasting and retains excellent definition when polished.
- Our equipment and specially designed programmes allow the Laser Development Department to laser mark multiple items at the same time. This is an area of ongoing development at Sheffield Assay Office.
We can perform trials and simple tests for quick evaluations of product feasibility.
Laser marking is cost effective for one-offs and prototypes, allowing small quantities to be produced without the need for expensive tooling or volume production. We accept drawings via email in popular formats such as: dxf, dwg ai, cdr, jpeg, bitmap or pdf. We have expertise in the transfer of design from scanned image to computer graphic that can be programmed into the laser machines.
A skilled technician ensures that the lasers are correctly formatted and running smoothly before an operator takes over to processes the work. We will quote for designing a programme, and then arrive at optimum timings from which item charges will be determined.
