Casting variety.

We offer variety

Whether you require high-quality unfinished castings or fully processed products right up to complex components, large individual pieces or large-scale production of delicate castings – we fulfil your requirements.

We advise your engineers on all issues of casting technology, recommend the most suitable material qualities for the job in question, and show you exactly how the various pattern options will affect the casting price.

Extremely interesting for you: we maintain an information database, which is continually updated, enabling us to provide you with the latest information as quickly as possible. All the project details you give us will be treated in the strictest confidence and are used for one purpose only: to fulfil your order in the best possible way to your fullest satisfaction.

You can rely on it:

First-class quality

Our quality standard brooks no compromise. That’s why we give you a product guarantee on all supplied goods. Product liability issues are always settled in strict accordance with German law, regardless of production site location. Our foundries manufacture in accordance with the requirements of DIN ISO 9001 and the quality of our castings corresponds to this standard.

Reliable delivery dates

We only work with foundries we can rely on. However, if something unforeseeable does occur, we are able to resolve bottlenecks in a flexible manner. As a result, we are usually able to guarantee an agreed delivery date.

Best price-performance ratio

We are able to maintain excellent price security thanks to our extensive market experience and our independence. We know what a certain part may cost and who will be able to manufacture it on time and at the desired level of quality. That’s why we can offer guaranteed fixed prices for a set period of time.

Mould technologies

Casting metal parts is one of the oldest known production processes. Metal jewellery and utensils were made by casting molten metals in a mould as far back as the Early Bronze Age.

Discoveries that suggest small production series confirm this. The simplest moulds were used for one-off casting of busts and statues and were smashed to separate them from the casting after cooling: a technique that survives to this day in bell founding in the form of “break-moulds”. Nevertheless, it would be impossible to imagine our high-tech world without castings.

Sand casting

Your Subtitle Goes Here

With sand moulding, the pattern is shaped in the sand. The pattern is then removed and the hollow space that remains is used to cast the molten material.

Waste-wax casting

Your Subtitle Goes Here

In waste-wax casting, small to tiny castings are produced using the lost wax technique. This process is characterised by its level of detail, dimensional accuracy and surface quality.

Chill casting

Your Subtitle Goes Here

In chill casting, the molten metal is poured through an sprue into a permanent metal mould, which is called a chill.

The pattern is shaped vertically in the sand with high pneumatic and hydraulic moulding forces combined with very fine moulding sand facilitating a special surface finish and contour fidelity.

Lost-foam casting

Your Subtitle Goes Here

In lost-foam casting, liquid metal is cast directly in a polymer pattern embedded in quartz sand. The hot metal causes the thermal decomposition of the pattern, taking on its shape.


Your Subtitle Goes Here

In diecasting, the liquid material is compressed and solidified in a diecasting mould by means of very high mould filling speed and high pressure. The pattern required for this process is called a diecasting mould.

One of our partner foundries, ORTRANDER, has been supplying thin-walled, weight-saving high-quality grey iron and spheroidal graphite iron castings for approximately 120 years, currently producing around 28,000 tonnes annually.

Innovation and flexibility, paired with the expertise our employees have developed over many years, are the foundation of the enduringly successful partnership. Grey and spheroidal graphite iron casting materials are cast on box-less moulding machines with vertical parting (DISA system). ORTRANDER has been using this technology for many years – a period during which the firm has acquired a wealth of knowledge and expertise. And the right touch. To the benefit of our customers.
