Metal quotations

You can find the current daily quotation MS 58 1. V. here.

All cable glands and accessories made of brass are based on a brass quotation of EUR 150 per 100 kg for MS 58/1. If this quotation changes by EUR 12.50 upwards or downwards in each case, we will charge a surcharge or discount of 5% each.
The date of receipt of the order is decisive for the calculation.

Quality & responsibility

Our products are approved in numerous countries and markets. Our management system is certified according to DIN EN ISO 9001 and ISO 50001. 

The guarantors for our competitiveness are

  • Consistently high production quality
  • A high vertical range of manufacture, in some cases over 90%
  • Technical innovations
  • A clear sales policy
  • High flexibility, especially for special applications

We carry out internal efficiency analyses. In addition and independent of the DIN EN ISO 9001 certification, our products are approved for certain international standards and areas. This results in additional external quality audits by national and international certification bodies for our company, e.g. for ATEX products. In these as well as in internal audits, among other things, our analysis results, our quality system, product and processes as well as legal requirements are audited and the effectiveness is proven. 

We manufacture and sell standard catalog products as mass-produced goods for the electrotechnical installation sector, electronics for measuring and control technology and fittings for the heating and sanitary industry. We carry out changes in production processes or changes of sub-suppliers exclusively for the purpose of improvement and do not automatically initiate notification of all customers for standard articles.

Contracts or orders with sub-suppliers are subject to confidentiality and are not made available to third parties. 

As a manufacturing company and employer in the region, HUMMEL is aware of its social, ecological as well as economic responsibility towards its employees but also towards third parties. HUMMEL therefore supports, within the scope of its possibilities, numerous projects that harmonize with the corporate values.

HUMMEL is proud to already be able to point to a large number of environmental protection and energy-saving measures.

  • Thanks to a water treatment system, 100% of the water can be discharged into the sewage system after galvanic surface treatment.
  • The oil mist produced during machining is cleaned by a filter system and the exhaust air can be released back into the environment.
  • A heat recovery system uses the waste heat from the production machines and compressors to heat the production facilities in winter.
  • An energy-saving concept is in place for all new buildings.
  • A recycling concept is in place for the machining area. This means that the residual material can be recycled.

We are happy to convince external partners with our products and high quality standards.
