Quality chains for the highest demands

In order to meet the high demands placed on our products, we take quality assurance measures that are based on the high standards of the industry. This also means that we as a company are committed to a continuous, sustainable improvement process. This becomes visible through the inner attitude of all employees and permeates all activities in our company.

The continuous improvement process relates to our process, product and service quality and is an essential and indispensable part of our quality management system. The traceability and allocation of relevant products and documentation is a matter of course for a functioning quality management system. In the area of round steel chains for lifting purposes, the Machinery Directive 2006/42/EC also applies, which, among other things, regulates a standardised level of protection for accident prevention for machinery within the European Economic Area (EEA).

Qualified employees and our modern, well-equipped quality assurance laboratory play a key role in our internal monitoring and therefore make a significant contribution to our process reliability:

  • through the creation of tensile samples
  • through tensile tests up to 750 kN
  • through preparations
  • through hardness tests
  • through corrosion tests
  • and microscopies including final analyses

Heat treatment

Heat treatment is a process for treating materials by thermal or thermochemical action. The aim is to achieve optimized properties for a specific application or purpose. We operate our modern and fully automatic Cieffe multi-purpose chamber furnace line 24 hours a day, 7 days a week. The dimensions of the furnace chamber are 1,170 x 720 x 700 mm (WxHxD) and hardening batches weighing up to 1,000 kg can be treated in it.

All processes are carried out in a chamber furnace in a protective gas atmosphere with appropriate C-level control. It goes without saying that our employees have many years of experience in modern heat treatment.

The heat treatment process is permanently controlled by a CO measuring device and additionally monitored and documented by foil samples.
