Parts for wind turbines:
This makes LANGER the ideal partner for wind turbine manufacturers

Wind turbine manufacturers are playing a leading role in the energy transition. Since the start of their development, wind turbines have become ever larger and more powerful. At the same time, the demands on the components installed have been constantly increasing. The parts installed in a wind turbine today must withstand enormous loads, have a long service life and at the same time be cheap to manufacture.

LANGER supports you as a wind turbine manufacturer (in Germany and abroad) with robust parts that correspond exactly to your specifications. Throughout the project we cooperate closely with our customers in order to deliver exactly the wind turbine components they require.

A modern machine park and qualified employees are the basis of our high quality standard. We provide wind turbine manufacturers worldwide with custom-made injection-moulded parts in all batch sizes. In addition, we offer complete component groups and customer-specific injection-moulding tools.

Parts for wind turbines: Parts ranging from large to small to meet your requirements

Wind turbines are state-of-the-art structures that are made up of a huge number of, in some cases, very complex individual components. Many of these parts are exceptionally well suited for manufacture by means of plastic injection moulding. Provide us with a description of the requirements your parts have to fulfil.

Our offering is aimed at the entire spectrum of wind turbine manufacturers as well as their suppliers:
  • Onshore wind turbine manufacturers
  • Offshore wind turbine manufacturers
  • Manufacturers of horizontal-axis wind turbines
  • Manufacturers of vertical-axis wind turbines
  • Manufacturers of rotor blades for wind turbines
  • Manufacturers of geared wind turbines
  • Manufacturers of gearless wind turbines

Wind turbines manufacturing in Germany: How is a project conducted at LANGER?

As a full-service partner, we are ready to support you during every step of your project. A qualified contact person is available to help you at all times. This is how a project is conducted at LANGER:


Our specialists contribute their skills to your order right from the start. Qualified staff from different departments work together to find the perfect solution to cater for your needs. In this way, you profit from our wealth of experience and know-how during every phase of your project.

Design and development

We would be happy to take on responsibility for the planning, further development or the complete design of your parts. To this purpose, tell us what your parts are required for and which properties they should have. If you already have a draft design, we would be happy to help with its further optimisation.

Virtual simulation

A key component of our budget-oriented and efficient way of working is the virtual simulation of the parts production. Using state-of-the-art technology, we simulate and thus verify the manufacturing processes in a realistic virtual environment. Besides verifying the feasibility, this also enables optimisation and cost-saving potential to be discovered. The amount of waste is reduced to a minimum and thus also the costs for our customers thanks to virtual simulation.

Tool construction

We manufacture finished injection-moulding tools in a wide range of shapes and sizes and find the ideal solution for every order. State-of-the-art quality control measures and experienced employees guarantee the consistently high quality of our series-production tools, multi-component tools and prototype tools using computer tomography, laser scanning as well as optical and tactile measurement methods.

Parts production

5X1A4819 2022 12 13 13 59 12
Our core competency lies in the economical manufacture of precise plastic parts. The manufacture of your precision parts is automated to a large extent. Whether prototype, low-volume production or high-volume production: Your expectations with regard to the finished product are put into practice with absolute precision, including material drying.

Quality control

5X1A3759 2022 12 14 15 55 27
When you commission LANGER to manufacture injection-moulded parts, nothing is left to chance. After all, the key factors for the wind turbine parts are absolute precision and close tolerances. Our automated quality control process thus ensures that your injected-moulded parts precisely meet your expectations. If necessary, we also perform density checks. Meticulous measurement equipment management guarantees the reliability of all control processes.

Further processing

Injection-moulded parts are often ready for further use directly after cooling and require no rework. However, if the customer would like us to, we are happy to perform further processing steps such as cleaning-up and demoulding.

Logistics service

We deliver all around the world and are familiar with the challenges that can arise with international shipments. For this reason, we offer our customers comprehensive storage and logistics solutions including customs clearance and a transport service. In the process, we pay attention to continuous article traceability. We would be happy to enter individual agreements with regard to our customers’ post-series and spare-parts supply.

Full service for manufacturers of onshore and offshore wind turbines

LANGER offers you injection moulding with all-round service. We consider ourselves to be not only a service provider, we would also like to provide you with comprehensive support during your project. With our broad service portfolio that goes far beyond just injection moulding, we are ready to help you with every stage of your work. From the idea to the finished part, we are the ideal partner for every industry and every project.

Let us convince you, too, through our customer-oriented way of working. Close cooperation with our customers, transparency and on-time delivery are just a few examples of the qualities that distinguish us as a partner for your parts production. Our qualified employees welcome every new challenge and would be happy to also find the ideal solution for your project.
