About us

Willi Wader Group.
Your guarantee for quality products
from family tradition.

In our in-house production, we manufacture and process series-ready welded constructions, horizontal forgings, automatic turned parts as well as CNC turned and milled parts. Our production offers extensive expertise, state-of-the-art machines and high-precision testing equipment.
The raw parts we use for machining are purchased worldwide. Long-standing partnerships with foundries and drop forging companies enable us to procure the raw material optimally tailored to your needs. Continuous investments in the latest technologies and personnel development within the production ensure our and your demand for highest quality in the long term.
With regard to the casting trade, we offer an unbeatable price-performance ratio through close partnerships with companies from Asia, which are monitored on site by our own quality personnel. We take over the procurement, logistics including customs clearance, up to warehousing and just-in-time deliveries for our customers.

Your partner for sustainable
product development.

We accompany you from the idea to series production.

  • Blast furnace tap hole drilling tools
  • Forgings
  • Grate bars
  • Conveyor chains
  • Castings
  • Prototyping in plastic 3D printing process

Benefit from our many
years of experience.

As a technology leader, we have the claim to manufacture your product qualitatively and economically with the most modern manufacturing processes. For every geometry and size we have a portfolio of specialised forging partners who are perfectly suited to the application. Machining simulations with the latest equipment guarantee economical, high-quality and on-time production.
We are happy to support you right from the design process and offer you design work and prototyping using plastic 3D printing processes.

Always in the focus of all

For us, the idea of quality is an essential anchor for trust and security. Our quality management system has been certified for more than 20 years, currently according to DIN EN ISO 9001:2015. This enables us to monitor your products from the receipt of goods via in-process control to dispatch and to document the quality.
Our goal is the emission-neutral manufacture of our products. We regularly check all processes for environmental and climate compatibility. Resource-saving handling of raw materials is just as much a part of our self-image as the feeding of waste into recycling systems. For our common future.

Satisfied Wader-customers
all over the world.

The WILLI WADER Group is active worldwide in both sales and procurement of materials. On the purchasing side, a broad network of partners within the European Union including Germany ensures the highest quality and unique raw materials perfectly matched to every application. For an unbeatable price/performance ratio, we work together with partners in the Far East and Asia and with our own staff on site we already carry out quality inspections before transport in order to import only the highest quality materials. Our specialists deal with all customs related issues. On the sales side, a network of our own staff and specially trained local partners covers almost every corner of the globe and ensures personal and expert advice and services on site. On request, we take over all customs related tasks as well as the storage of stocks.

Blast furnace tap hole drilling tools

We have been producing taphole drilling tools for blast furnaces for over 40 years. Longer and longer tapholes, smaller drill diameters, harder taphole masses and shorter tapping times on modern blast furnaces required a constant development and improvement of our tools. Thanks to our excellent price-performance ratio and close cooperation with our customers, we have become one of the leading international manufacturers of taphole drilling tools.

One of the most important features of our drilling tools is to open tapholes cleanly, efficiently and economically. We are also constantly developing the operability of the tools to ensure safe and quick tool changes during operation.


In cooperation with our efficient suppliers and our own experience in the field of CNC machining, forging and welding technology, we offer our customers machined parts of all kinds based on castings, forgings, bar steel and steel sheet of greater thickness in the highest quality at reasonable prices.

Our quality system guarantees that the parts produced by us according to your drawings and specifications will meet your high requirements.

Conveyor chains

Willi Wader Systemtechnik GmbH

We have been specialising in the manufacture of conveyor chains for bulk material conveyors for several years. The main focus is on the production of drop-forged and sheet steel fork plate chains for trough conveyors. Conveyor chains made of round link chains are also part of our delivery programme. Our chains are characterised by an exceptionally high wear resistance and quality.

Our conveyor chains are manufactured exclusively in our own factories. Our delivery programme is very wide and we manufacture tailor-made conveyor chains according to the wishes of our customers.

Conveyor chains


We supply a variety of different product qualities of cast steel and cast iron, which can be either unmachined or machined. We can fall back on different manufacturing variants, in grey and nodular cast iron, alloyed cast iron, as well as steel, heat-resistant steel, wear-resistant steel and manganese steel castings.

Through years of experience, we can advise you in such a way that the finished part is optimally matched to your intended use in terms of material, wear resistance, toughness, heat resistance, etc., whether unalloyed, low- and high-alloy cast steel, cast iron with lamellar or nodular graphite.

Production techniques

  • sand casting
  • lost foam method
  • shell molding process
  • vacuum process
  • lost wax process


Range of application

  • wood combustion systems
  • power plants
  • waste incinerators
