Alternative power train technologies

Series-ready products for new mobility concepts

We already routing the technology of tomorrow

For many years, we have been developing functional and light-weight components, collaborating with leading automotive manufacturers. We also work together with our partners to find the road to future mobility and deliver reliable and proven technology as well as innovative solutions for new mobility concepts.

Of course, we develop and produce components at the highest technical level with robust added value for our customers. All this, we routing with our flair for engineering feasibility and our years of experience in reliable serial production.

Our experienced employees in development and production, the in-house know-how, our modern machinery for serial production, and the ISO-certified quality assurance guarantee to lead new developments into the production stage. This also applies to advanced mobility designs: High-quality components made by Joma-Polytec.

Joma-Polytec is also a pioneer of state-of-the-art mobility concepts.

Fuel cell (PEMFC)

We develop your mobility concepts and guarantee top performance

As an established supplier to leading automotive manufacturers, we provide our customers with functioning routing, production and development chains and reliable serial production.

In the automotive sector, the name Joma-Polytec has long been synonymous with effective solutions for increasing efficiency. As a result, we are also able to make an important contribution to the development of standard drivetrain systems for modern drive concepts, e.g., the polymer electrolyte membrane fuel cell (PEMFC).

Needless to say, our partners can also rely on a development towards the market-oriented and cost-optimised serial production of structural and functional components for fuel cells.

Our range of products includes various components and developments for modern drivetrain designs. If you’re interested in a detailed overview, we are looking forward to your inquiry.

Lightweight engine mountings made of plastic make an important contribution to increasing efficiency through weight reduction.

Light-weight and structural components

The foundation of efficient resource utilisation

Our light-weight and structural components make a significant contribution to the achievement of energy efficiency and resource conservation in many automobiles. These components are also an integral part of all future mobility concepts due to their weight saving ability.

Conception & component development from selected thermoplastics with high fibre content
Anisotropic strength analyses (consideration of the fibre orientation)
Detailed validation and testing, mould flow analyses
Engine and transmission carriers, end plates, assembly carriers, brackets

Our goal is to design the ideal part. Each and every time: Maximum stability with minimum weight. At the same time, we develop innovative solutions for durable plastic parts with a compelling design—always at the edge of feasibility. Load-bearing parts are produced in a fibre-reinforced manner or in a material mix with various metals.

In addition to sheer weight-saving and stability, our plastic carriers accomplish important functions and are used in many vehicle applications, e.g., thermal management, the reduction of vibrations or emissions. Which part would you like to optimise?

Thanks to an optimum material mix, our pumps achieve reliable maximum performance with minimum weight.

Vacuum and Hydraulic pumps

Sophisticated technology for new concepts

We have been developing vacuum and hydraulic pumps for conventional vehicles for many years. Together with our experience in light-weight construction, we are also developing suitable solutions in the area of media conveyance for the mobility concepts of the future.

Design, construction, simulation, validation
High efficiency/high performance, optimised weight, good acoustics
Diverse variants for different fields of media conveyance applications, e.g. mechanical single-leaf pumps, mechanically driven pumps which can be switched off, electrically driven pumps and dry-running vacuum pumps, lube oil pumps
Individual adaptations to customer requirements

In addition to oil-free and oil-lubricated vacuum pumps, our variable displacement vane pumps and external gear pumps are also found in many engine and gearbox oil circuits.
Thanks to our many years of know-how in the manufacture of hydromechanical components, we achieve extremely high service lives with consistent reliability and performance.

All of our pumps are developed in-house with serial production in mind and are subject to extensive long-term tests during this process. Ask us about individual solutions to your challenges.

Media routing

Reliable and tried and tested

Our integrated media conveyance systems are well-established in many vehicles of leading manufacturers. We develop suitable solutions for the mobility concepts of the future.

Cooling water parts, oil pipes, transmission oil sump with filtration, intake manifolds
Flow and strength analyses
Innovative manufacturing processes, e.g., lost core methods
Validation/testing, mould flow analyses

The combination of different injection moulding processes and subsequent production steps such as assembly (manual, semi-automatic or fully automatic), welding, printing, laser, thermal forming and subsequent component testing, enables us to solve the demanding specifications of our customers.

The use of innovative manufacturing processes, e.g., lost core methods, lets us design components with the most complex geometries. All components are developed by our experienced engineers. Starting with the prototype to the series part. Each part is subject to different flow and strength analyses, mould flow analyses, and a final validation before it goes into series production.

As one of the few suppliers, we routing the complete oil or air circuit for the vehicle’s system. Let us know if you have any questions.
