THE COMPANY

History:

1924: Founding by Ferdinand Schwarz in Düssel-dorf-Grafenberg. 1943/44 moving the company, fully destroyed during the war, to the Thuringian Grabfeld to Römhild.

In 2002 the company was bought by Dirk Becker and Axel Engels and has been ambitiously expan-ded since then. The product spectrum was incre-ased, internationalization was promoted and the

efficiency substantially increased

Industries supplied:

> Automotive> Aluminum> Chemicals> Electronics / Electro-technology> Drive technology> Glass> Rubber> Ceramics> Plastics> Aerospace and space travel> Metal processing> Pharma> Steel> Textiles and fibers> Connection technology> And many more

Competitive advantages:

> Flexible medium sized company with expert hi-erarchy and many years of Know-How.

> Greatest possible heat efficiency and economy, very modern office and production facilities.

> Owner-led company.

> Short delivery times also for customer-specific solutions.

Employees:

Approximately 80 employees of whom more than 20 are engineers in development and works pre-

paration.

Service:

Qualified service technicians advise our custo-mers throughout the world.

KWA 400 – Heat treatment furnace

A heat treatment plant was designed for the well known machine tool manufacturer RENNSTEIG-WERKZEUGE GmbH in Viernau/Thuringia (since 1991 a subsidiary of the KNIPEXWerke, Wuppertal).

The retort-less heat treatment furnace is used for the carburizing-neutral hardening of steel parts of up to 400 kg/h in the run-through procedure. A protective gas generator in connection with a defined amount of carburizing gas makes possible the setting of a concrete carbon potential that is determined by means of an oxygen sensor. Ventilators with a low speed ensure good gas distribution in the austeni-zing furnace.

The construction design of the whole plant was ad-apted to the parts spectrum. It ensures the treatment of sheet-type parts with 2 mm thickness and 30 mm diameter up to parts with a large degree of slimness at a maximum length of 600 mm.

An oil quenching bath ensures optimal quenching of the heat treated goods with low own effort.An adjoining immersion washing machine with after-treatment provides a particularly good cleaning ef-fect. The parts are fed in a dry state to the tempering furnace. Washing water drain losses are replaced by means of auxiliary energy-less dosing arrangements in an environmentally friendly manner.

The tempering furnace is sufficiently dimensioned and permits the tempering of large parts.An intensive circulation ensures quick and even hea-ting of the goods up to a maximum of 500 °C.

All heaters of the plant can be exchanged while hot (without power). The switch and control installation is designed for fully automatic operation; PCs with operating terminals visualize all processes and set values. Various programs can be stored and quickly called up with the keyboard.

If required, the plant can be equipped with a feeding machine and a weighing installation. Special software makes possible performance adaptation in peak pe-riods of the electric energy supplier.
