Electric car and wallbox charging station:
This is how we help you with our plastic components

Electric cars are the mobility market of the present with a future. New drive technologies are on the rise and are intended to significantly reduce the burden on the environment. Also from a practical point of view, 100% electrically powered cars offer many advantages as an alternative to the internal combustion engine. Their manufacture, however, involves numerous challenges for the automobile industry and its suppliers. The design of electric vehicles is undergoing constant further development through new innovations and optimisations. Suppliers must be particularly flexible and customer-oriented in this dynamic environment.

LANGER specialises in the manufacture of high-precision plastic parts in the field of e-mobility. Our aim is to deliver components for electric cars that enable you to make progress in your project. That is why we work closely with you right from the start. With state-of-the-art manufacturing methods, we would like to push back the boundaries of economical feasibility.

We manufacture customer-specific injection-moulded parts in low- and high-volume production. Our core competencies also include the manufacture of injection-moulding tools as well as design and assembly. From the simple injection-moulded part to the complex component group, we find the best solution for every order.

As a manufacturer of electric cars and accessories, you profit from our service portfolio and our high degree of flexibility. Thanks to short decision-making paths, customer-oriented production control, 24-hour production and express service, we always react to your wishes and suggestions within a short period of time.

Not only customers in the automotive sector appreciate our high degree of customer orientation, we also advise and deliver to customers in the construction, medical technology, mechanical engineering and electrical engineering industries. LANGER has all the necessary expertise for parts production available in-house. For you this means: all services from a single source and a single contact person for all issues. We use EDI for straightforward communication with our customers.

High quality for high standards: Manufacture of plastic parts for electric cars and wallboxes

We implement your wishes in plastics engineering precisely down to the last detail. Our plastic injection-moulded components meet your specifications within a hundredth of a millimetre and have precisely the desired material properties. Automated quality control and sample inspection according to PPAP or PPF ensure a uniform quality standard.

LANGER uses a wide range of different high-performance thermoplastics, with or without glass fibre reinforcement, depending on the requirements. If required, it is also possible to mix in certain colours. Our portfolio includes bespoke packaging, a transport service as well as storage of components.

Exemplary with regard to quality and sustainability: Electric-vehicle parts manufactured with responsibility

In keeping with the spirit of the mobility turnaround, LANGER sets great store by sustainable manufacturing processes. We constantly strive to conserve resources and reduce waste to a minimum. In addition, we recycle plastic and offer reusable packaging.

Advantages of injection-moulded plastic components for e-mobility

The alternative drive technology is far from being only difference between electric cars and vehicles powered by internal combustion engines. The electric drive influences the entire vehicle design. This results in various challenges, but also opportunities. Innovative and high-quality solutions made of plastic are essential for the continuous optimisation of electric cars.

Examples of possible applications for injection-moulded plastic components in the field of e-mobility:

Electric car: Reduce weight without affecting the stability

In order to extend the range of electric vehicles and to compensate for the high weight of the batteries, the weight of electric vehicles must be reduced to the greatest extent possible. This, of course, must not be at the expense of stability and safety. Specially manufactured plastic parts have already been used for a long time to minimise the own weight of vehicles. With increasing technological progress in the e-mobility sector, the demand for ultra-light and hard plastic parts will increase further.

Drive concept for electromobility: Compensate for lack of heat using plastic

Unlike internal combustion engines, electric motors hardly produce any heat. In the cold months it can become a challenge to maintain a pleasant temperature in the driver's compartment in conjunction with an acceptable energy consumption. Certain plastics have excellent thermal insulation properties and can help to remedy this situation. At the same time, they can protect the sensitive battery against temperature fluctuations.

Electric car: Prevent driving noises

It is common knowledge that alternative drive systems for cars are significantly quieter than conventional engines. However, this means that noises that are in themselves very quiet, for example rattling sounds, become increasingly more noticeable. To ensure that these do not disturb the passengers, sound-absorbing plastic parts can be installed that reliably suppress this type of noise.

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

When you commission LANGER to manufacture injection-moulded parts, nothing is left to chance. After all, the key factors for e-mobility 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. If desired, 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.
