Precision Throttle Plate Manufacturing for Air, Gas, and Liquid Flows

Ein Transferwerkzeug in unserer Produktion

Throttle plates regulate the flow of air, gas, or liquids in technical systems. Depending on the application, they perform control, metering, or shut-off functions and must operate with precision and reproducibility over many cycles.

Jehle AG manufactures ready-to-install throttle plates for customers with high demands on dimensional accuracy, process reliability, and production quality. Our focus is on medium to large production volumes. Manufacturing is carried out using an integrated process chain and coordinated inspection procedures.

Applications and Key Requirements for Throttle Plates

Jehle AG manufactures throttle plates for technical applications in which air, gas, or liquid flows must be controlled. The requirements vary depending on the medium, temperature, material, installation space, and function.

 

Engine and Exhaust Systems

In engine and exhaust systems, throttle plates regulate the flow of air or exhaust gases. In the intake system, they control the amount of air entering the internal combustion engine.

In EGR systems, they facilitate the recirculation of exhaust gases into the intake tract.

For these applications, tight tolerances on the outer diameter, a defined control edge, and consistent quality in series production are essential. At higher temperatures or when exposed to aggressive media, suitable materials such as stainless steel or application-specific special alloys are used.

Other Potential Applications

Throttle plates with comparable dimensions, materials, and manufacturing processes can also be used outside the automotive sector. The key factor is whether the geometry, material, medium, temperature range, and production volume are suitable for the application.

Our Manufacturing Process

Jehle AG manufactures throttle plates using closely coordinated, automated process chains. This lays the foundation for stable mass-production processes, consistently repeatable components, and cost-effective manufacturing for medium to large production runs.

1. Stamping of blanks from coil or strip material using progressive die tools

2. Automated handling and further processing

3. Mechanical finishing and edge processing

4. Process-integrated quality control

5. Part finishing and technical cleanliness

Our Manufacturing Technology

Three core technologies form the basis of this process chain:

  • Progressive stamping and high-speed presses

  • Automated throttle plate machining centre

  • Integrated deburring and cleaning processes

Quality and Certifications

Jehle AG ensures quality through process integration. Inline measurement and inspection systems record defined dimensions in real time and enable adjustments to be made directly during the ongoing process. This ensures reproducible results in series production, even with high production volumes and tight tolerances. As an automotive supplier certified to IATF 16949 and ISO 9001, we meet high quality standards.
