Amethyst Designs Limited successfuly accredited to new ISO 9001 and ISO 14001 standards

Amethyst Designs & REACH Compliance

Read the full letter here. [PDF]

Amethyst manages its supply base through its documented quality and environmental management system via approved suppliers. The manufacture of transformers and coils of course requires the use of various solvents and resins but all of these are standard industry products that are not imported or manufactured specifically for us.

Amethyst Compliance Status

Under the regulations, we are considered downstream users. We believe that to the best of our knowledge, all substances within the products we sell have been identified and our suppliers have been contacted to confirm that all substances are registered by our supply base where appropriate.

In view of this we do not believe we have any further direct obligations under REACH Regulations. We do, however, recognise our continuing role in achieving full compliance with the legal requirements of REACH. This we will do via communication of information to relevant suppliers and stakeholders regarding volumes and usages of the substances in the products we supply. We will review this on an annual basis.

If you require any additional information please do not hesitate to contact me.

Paul Wealleans,
Operations Director.


Milan Vjestica, formerly of Walsall Transformers and Clairtronic / Dagnall Electronics joins Amethyst Designs.

January 2010

We are pleased to announce that Milan Vjestica has joined Amethyst Designs.  The modern facilities and approvals at Amethyst  are most suitable for the continued manufacture of  products for the customers that Milan brings with him.

Milan has over 30 years experience in the transformer industry,  having built up a loyal customer and supplier base. He has knowledge of mains laminated, high frequency ferrites, and toroidal transformers and is able to offer customers a full technical sales/design service from initial design concept/enquiry through to full after sales care.

Milan's design experience also adds to our already strong design team to provide full technical support for all Amethyst customers.

Milan has considerable expertise in design and manufacture of higher volume transformers and coils. This enables Amethyst to offer the full one stop service from design concept to high volume supplies at competitive prices.

Amethyst are also able to offer equivalent products for the catalogue style range of products that were previously offered by Walsall Transformers and Clairtronic / Dagnall Electronics.

Milan can be reached directly by phone on 0121 286 1435 or via his new email address

Grant's remit is to be responsible for the manufacture and quality control of Morite Windings wound components and to provide technical support for all Amethyst customers.

Grant can be reached directly by phone at Amethyst or via his new email address
