Useful information about metal

By compacting aluminium chips in a briquetting press, Carbomill AG reduces logistics costs, saves valuable coolant and increases revenue from recycling.

Sustainability in the industry is no longer an optional extra. It is increasingly being demanded – by customers, partners, throughout the supply chain and by regulatory frameworks. We show how briquetting enables measurable sustainability – without the need for production overhauls!

Raw materials have become a strategic bottleneck. Geopolitical risks, price volatility, and new EU regulations such as the Critical Raw Materials Act are increasing pressure on companies. The key question is: Where do avoidable material losses occur – and how can they be reduced economically? 

RUF Formika briquetting system in direct use at turning and milling machines

In 2021, RUF launched its small, mobile Formika briquetting system. Since then, it has been sold many times over – and not only that. Day after day, the machine also proves its long-term performance in RUF’s own production. 

Büttner PräzisionsWERK GmbH was the first customer to test the RUF Formika – and was immediately impressed. Today, two systems optimise chip processing directly on several machining centres, making a significant contribution to the efficiency of the company’s chip logistics.

Carl Zeiss Sports Optics uses specialised RUF presses for small chip volumes at its machining centres

With three particularly compact and mobile briquetting systems of the Formika type from RUF Maschinenbau GmbH & Co. KG, Carl Zeiss Sports Optics presses aluminium chips from machining operations into almost dry briquettes.

Everllence/MAN Energy Solutions closes the material cycle with presses from RUF

Everllence compresses the cast chips produced during manufacturing into compact briquettes, which are then remelted again in its own foundry. In doing so, the Augsburg based company, known as MAN Energy Solutions until early June, closes the material cycle and reduces costs. Three briquetting systems from RUF are in operation, processing well over a thousand tonnes of chips per year. RUF is now upgrading one of the briquetting presses to expand production.

HAI confirms Short Payback Period for RUF Briquetting Systems

The Hammerer Aluminium Group uses RUF briquetting presses to efficiently close the material loop. When aluminium chips from production are compressed into briquettes and then remelted, the material yield is approximately eight percentage points higher than when melting loose chips. Using their own, precisely defined materials also ensures consistently high alloy quality.

For almost 25,000 hours, a press compacted grinding sludge into briquettes. Now it has been replaced by a new system. Technology and service from Hunkeler Systeme AG were convincing.
