As an OEM hose supplier and system supplier for series production, MST-Flexduct supplies international OEMs and Tier-1 suppliers in automotive, aviation, rail, mechanical engineering and plant engineering with ready-to-install line systems. The difference from a classic hose supplier lies in the depth of integration: MST-Flexduct accompanies projects from the early development phase through PPAP validation to stable series supply.
With vertical integration of up to 80 %, several international production sites and seamless quality and logistics processes, MST-Flexduct offers the supply security that OEM series environments require. Delivery dates are plannable, quality values reproducible and process documentation audit-capable.
MST-Flexduct as an OEM Supplier
OEMs need reliable suppliers that not only deliver components but also provide stable processes, consistent quality and plannable capacities. MST-Flexduct is specialized in exactly these requirements.
At MST-Flexduct, the role of OEM supplier goes far beyond the manufacture of individual parts. Development departments are supported as early as the initial project phases. Prototype manufacturing, component validation in close coordination with design and quality assurance as well as the stabilization of series processes together with supply chain and production are an integral part of the collaboration. The interplay of technical expertise, process reliability and economic stability makes MST-Flexduct a reliable partner for long-term series programmes.

Supply Chain Integration (JIT/JIS)
MST-Flexduct’s logistics processes are geared to the requirements of modern OEM supply chains. Forecasts and call-offs are processed transparently, capacities are planned stably, and critical components are secured where necessary via redundant production lines. Coordinated logistics routes, defined packaging and provisioning concepts as well as customer-specific labelling ensure that all line systems reach the OEM’s assembly process without delays and without quality deviations. For manufacturers, this means a plannable, reliable supply without bottlenecks and unnecessary downtime risks.
Quality standards & traceability
In the OEM environment, quality is not just a promise but a measurable variable. At MST-Flexduct, all manufacturing and inspection processes are clearly structured, documented and audit-capable. The line systems are validated against defined inspection specifications, from the raw-material batch through the layer structure to the final series part. In this way, MST-Flexduct meets the requirements that OEMs place on safety-critical and function-relevant components.
We guarantee:
Complete traceability of every batch in accordance with IATF 16949, AS9100 and IRIS
Documented material inspections with material certificates to EN 10204
Series approvals according to customer-specific specifications and PPAP levels 1 to 3
Ongoing quality monitoring with statistical process control (SPC)
Inspection protocols for mechanical, thermal and normative requirements
Consistent tolerance management and dimensional accuracy across the entire series
Industries & OEM references
MST-Flexduct has been working for many years with international OEMs and Tier-1 suppliers across a wide range of industries:
Automotive: Air routing, hot-end area and thermal management in passenger-car and commercial-vehicle drivetrains. Qualification to IATF 16949. PPAP scope of supply on request.
Aviation: ECS systems, drainage lines and climate air routing to FAR 25.853 / CS-25 and ABD 00031. Series approvals to AS9100 with complete delivery documentation for approval authorities.
Rail: HVAC applications and technical supply air in rail vehicles. Standard conformity to EN 45545-2 and IRIS (now ISO/TS 22163). Inspection reports for fire-protection classes HL1 to HL3.
Mechanical & plant engineering: Process air, vacuum applications and cooling media in industrial and manufacturing plants. Design to customer-specific specifications, series delivery with defined tolerance management.
Energy & industrial technology: Hot air, exhaust gas and material handling in power and process plants. Temperature-resistant line systems up to +400 °C with fire-protection evidence on request.
Regardless of the industry, OEMs always benefit from MST-Flexduct’s ability to reliably transfer complex line systems into stable series environments.
Advantages for your series
Working with MST-Flexduct offers OEMs decisive advantages for the stability and cost-efficiency of series production:
Economical series production through vertical integration of up to 80 % in-house
Consistent quality values with statistical process control across all batches
Reduced assembly times through ready-to-connect assemblies including fittings and fastening elements
Low process risks through an international site structure with redundant production lines
Plannable supply chains through JIT/JIS-capable logistics processes and long-term capacity planning
Technical support based on the APQP methodology during development and series launch
High variant capability with reproducible quality results at the same time
This combination makes MST-Flexduct an ideal system supplier for long-term programmes – from the prototype to the late series phase.
Why MST-Flexduct as an OEM hose supplier?
OEM series place the highest demands on stability, repeatability and supply security. Deviations in material, geometry or tolerances lead directly to quality risks, assembly problems or production stoppages. A hose supplier that does not understand these interdependencies becomes a weak point in the supply chain.
MST-Flexduct combines technical know-how, process-reliable manufacturing and robust supply chains into a complete package developed specifically for OEM requirements. The line systems are manufactured so that they exhibit identical properties in every batch, integrate seamlessly into existing assembly processes, and at the same time meet the economic requirements of modern series production.
