Hiostory of the Metallgießerei Ralf Mewes GmbH
Synonym for quality work from a special mould
Foundation of Metallgießerei Ralf Mewes GmbH
At the age of 20, Ralf Mewes set up his own business on 1 February 1986. In 1987, Metallgiesserei Ralf Mewes was founded, which was then transformed into Metallgiesserei Ralf Mewes GmbH in 1996. The company initially only dealt with aluminium chill casting and its processing. It expanded continuously. In 1991, Ralf Mewes (RM) took over the production of the Nettelbeck/Ostermann foundry. With this transaction, the company grew very rapidly, so that RM bought a plot of 5,950 square metres in the Röbeck industrial estate in 1995. This plot was then developed in 1997 with a hall and office wing with a total area of 3,850 square metres. In the meantime, the company had become an integral part of the industry as a full-service provider of toolmaking, foundry, mechanical processing and finished system components. In 2002, another toolmaking shop and a high-bay warehouse were added, increasing the production area to around 5,000 square metres. Over the following years, several small foundries were taken over. In 2015, the production and property of Grundscheid GmbH was taken over and renovated on an area of 8,500 square metres, our current Plant 2, which houses the warehouse and a state-of-the-art CNC machining facility with 3-, 4- and 5-axis machines.
Since 2009, the next generation has also been established in the RM Group with Kevin Mewes, who became a partner and joined the management board in 2014, setting the course for the coming decades.

We are also happy to be your contact for brass and zinc castings as well as metal goods.

Our company was one of the first aluminium foundries to be certified to DIN EN ISO 9001 back in 1996. On 21 February 2003, we were re-certified by AEROCERT in accordance with DIN EN ISO 9001:2000, a clear sign that quality is the be-all and end-all of our company philosophy. In order to meet the increasing demands of the times, we moved into a spacious new building in 1997. 3,000 square metres of production space, expanded to 5,000 square metres at the beginning of 2001, and a modern machine park provide the ideal conditions for remaining on the road to success. Today we have a production area of 12,500 square metres at our disposal.
Extension Factory 1 Metallgießerei Ralf Mewes GmbH
Today, we produce around 80 tonnes of aluminium gravity die castings per month. After all, this material of the future has a number of convincing advantages: In addition to its low weight, high ductility, good thermal and electrical conductivity, high weight/strength ratio, wide range of finishing options and excellent corrosion resistance, it is also its incomparable recyclability and attractive price/performance ratio that speak in favour of using aluminium.
However, it is not only technical expertise in the field of aluminium, stainless steel and cast iron that sets us apart, but also the partnership-based cooperation with our customers. Around 1200 companies from a wide range of industries, including mechanical engineering, the automotive industry, the furniture industry, sun protection technology, the construction industry, the stone and earth industry and medical technology, rely on the quality work of Ralf Mewes GmbH.
Rebuilding Fatory 2 in the Haberstraße 8 – 10 in Velbert (NRW)
In 2015, we took over the property, machines and customer base of Grundscheid and rebuilt our current Plant 2, which houses a state-of-the-art CNC machining centre, assembly and warehouse. Thanks to large reserves in the total area, further growth in the group is assured.
Well-known companies such as MAN, Siemens and Daimler are among our regular customers. Our success as a casting supplier is reflected in figures not only in Germany, but throughout Europe and worldwide: we realise 12-15 percent of our annual turnover in other European countries. Germany’s neighbouring countries Austria and Switzerland play a major role in this.
Acquisition of Gestaguss GEW in Velbert
Acquisition of Gestaguss GEW in Wetterzeube
The Gestaguss foundry group was acquired on 1 September 2007. With around 65,000 square metres of operating space, it was the largest acquisition in the company’s history. This purchase consisted of an iron foundry established in the 1960s with an operating area of around 20,000 square metres where grey cast iron, chilled cast iron and malleable cast iron were produced. Today’s GEW Guss GmbH is the last iron foundry of its kind in the Mettmann district, out of the 65 foundries in Velbert. It also includes Gestaguss GEW Edelstahlgießerei GmbH in Wetterzeube (Saxony-Anhalt) with a production area of around 45,000 square metres. This production facility, which celebrated its 100th anniversary in 2009, produces steel and stainless steel castings in over 200 different alloys. Today, Gestaguss GEW produces around 1,000 tonnes of steel and stainless steel, as well as approx. 1,000 tonnes of grey cast iron, malleable cast iron and chilled cast iron.
Castings are supplied to all conceivable branches of industry at all locations.
