About Hean Studio

Studio Home

Since it's beginning in 1970, Hean Studio Ltd has steadily established itself at the forefront of quality precious metal casting. We have worked with some of the finest Goldsmiths silversmiths and jewellers in the land.

We offer a range of high quality services. Precious metal casting, quality mould making and waxing and advanced CADCAM services.

From individual tiny collets, all types of jewellery parts, watch case components to sculpture, trophies and Objets D’Art.

We also provide specialist Platinum alloy casting services for high tech industries including Scientific, Medical, Aeronautical and Automotive.

Problem and challenging items have always been a speciality, and we can usually find a solution.

In 2000 we invested in CADCAM (Computer Aided Design and Manufacture) services, to assist customers with the design and production of master patterns and one-off projects.

We only use metals from approved bullion suppliers.

We guarantee never to infringe the copyright of our customer’s master patterns and designs. 

We welcome customer visits to our advanced facility in Herefordshire.






Bullion Supplies.

All the bullion used at Hean Studio is supplied through recognised suppliers of high quality bullion products.

They are:

  • Cookson Precious Metals (Part of the Heimerle & Meule Group)
  • Metalor Technologies Ltd,
  • Umicore (Allgemeine).

These companies only procure raw materials through resources that can demonstrate well-managed procedures for minimal environmental impact. However, as the jewellery sector is the only industry that has for over 4000 years recycled 100% of its products, you will appreciate that up to 80% of new materials may be sourced from recycling. So our metal is a combination of recycled and fresh material sourced from producers compliant with the policies of the responsible jewellery council.

In house we maintain a strict regime of cleanliness and control to prevent any erroneous contamination of materials. Any materials that show signs of contamination, and returned materials that have been worked upon, are kept separate and subsequently refined for re-use.


Nickel Directive Compliance.

Back in the late 80's when the nickel directive was still at the discussion stage, Hean Studio Ltd, took steps to accommodate the eventual legislation. By 1989 ALL our production alloys we re-developed to eliminate the nickel content, whilst still maintaining the best quality material properties for the benefit of our manufacturing clients, and ultimately the public.


Ethic Statement.

Equality Statement

Hean Studio Ltd has always embraced a policy of the highest ideals in all areas relating to equality.

We have full facilities for disabled people, and are able to offer equal opportunity employment in certain production areas for persons who may be wheel chair bound, but fully able from the waist upwards. We will always consider any applicants on there abilities, and endeavour to accommodate personal needs.

Ethnic origins, beliefs, and personal orientation, have never been an issue, and we take a positive attitude to working together as a team. As with every business there is a formal structure, which is necessary for a well-run business, but every one is made to feel comfortable, and encouraged to feel they are an equal when interacting with others at any level.


Personal honesty, integrity, communication, and high standards of work throughout the work force are the driving strength of our team.

We diligently and actively maintain a policy of protecting our customer's original designs, and with the CAD/ CAM bureau services we will not create copies of designs where we are aware that a design copyright may exist with another party

Environmental Compliance.

Hean Studio is situated in a rural setting surrounded by glorious Herefordshire countryside, and we strongly wish to protect the natural world for future generations.

The new building, although it may appear to be somewhat traditional in style, is in fact an efficient modern building. There are a number of subtle architectural features that reduce thermal build up in the summer, reducing cooling costs, and at the same time a high level of insulation to minimise heating requirements in the winter.

Bi-products of the casting process. The largest quantity of waste is the left over slurries consisting of casting mould refractories. This consists mainly of gypsum, the same material that makes up the White Cliffs of Dover. This is retained in a slurry pit which when filled is emptied by a licensed waste disposal company. This material is totally inert and is NON-toxic.

Acids used to clean the castings are kept to a minimum by using diluted solutions in heated tanks that are fully enclosed, and the extraction systems "scrub" the air to neutralise it. Spent acids are fully neutralised using the waste gypsum from the casting slurries. Regular tests have demonstrated that these acids have been totally neutralised, and have no further impact.

We have recently had the heating and cooling plant renewed with heat exchanger style units, so we no longer burn any gas on site, thus significantly reducing the amount of carbon dioxide produced at this site.
