Subassembly Assembly
From individual parts to ready-to-install subassemblies: We handle the
complete assembly of your plastic components.
Tested, packaged, and ready for your production line.
Assembly and Injection Molding from a Single Source
Our subassembly assembly combines injection molding production with downstream assembly in a continuous process.
The result: ready-to-install subassemblies delivered directly to your line – without additional intermediate steps on your part.
At Schröder + Heidler, we not only manufacture individual parts but also, upon request, handle the complete assembly, testing, and packaging of your subassemblies. By closely integrating injection molding and assembly under one roof, you save on logistics, shorten lead times, and receive everything from a single source.
- Reduced coordination effort through a single point of contact
- Shorter supply chains – production and assembly at the same location
- 100% testing integrated directly into the assembly process upon request
- Flexible packaging solutions according to your specifications
- Scalable from small to large series
More than just “simple assembly”
Our subassembly assembly goes far beyond simple joining. We plan the assembly process together with you, develop efficient workflows, and rely on reproducible quality at every step. Whether clipping, screwing, pressing, ultrasonic welding, or bonding – we select the appropriate joining method and integrate testing steps directly into the assembly line.
-
Reproducible Quality
Standardized assembly processes and integrated testing stations ensure that every subassembly precisely meets your specifications – piece by piece. -
Diverse Joining Technologies
From mechanical connections to welding processes and adhesive bonds.
We master the entire spectrum of industrial joining technology for plastic subassemblies. -
Economical Processes
The direct link between injection molding and assembly eliminates transport routes, intermediate storage, and unnecessary interfaces – reducing costs and increasing delivery reliability.
Application Areas in Subassembly Assembly
Our assembly services are used across industries – wherever ready-to-install solutions are required.
Electrical Engineering
Housing assembly, equipping with contact elements, and assembly of connector subassemblies – tested and ready for installation in electrical engineering.
Automotive Industry
Assembly of functional subassemblies for vehicle interiors and engine compartments – IATF 16949 qualified and with seamless traceability.
Consumer Goods and Mechanical Engineering
From multi-part housings to control units and functional subassemblies with seals and springs – ready for assembly and packaged according to your specifications.
From inquiry to finished subassembly. In three steps.
We support you from assembly planning to series delivery. Our structured process ensures transparency, efficiency, and consistently high quality.
Assembly Planning and Concept
Together, we define the optimal assembly process, establish testing criteria, and plan packaging – tailored to your logistics and production requirements.
Fixture Construction and Sampling
We develop assembly fixtures and test gauges, conduct initial samples, and optimize the process until all quality parameters are consistently met.
Series Assembly and Delivery
In ongoing series production, we reliably assemble, test, and package your subassemblies – with just-in-time or just-in-sequence delivery directly to the line, upon request.
Why Subassembly Assembly at Schröder + Heidler?
Everything under one roof – from part manufacturing to ready-to-install subassemblies. This saves time, reduces costs, and provides you with a reliable partner.
In-house Toolmaking
The tools for your components are created directly by us – short distances between toolmaking, injection molding, and assembly ensure quick adjustments and maximum precision.
Flexible Machine Capacity
With our extensive machinery, we manufacture all individual parts of your subassembly in-house – from small parts to larger structural components, all economically and on schedule.
Certified Quality
Our assembly is subject to the same quality management system as our injection molding production – certified according to ISO 9001:2015 and IATF 16949:2016.
Assembly Included
Does your subassembly require multi-component parts? No problem – our 2K injection molding seamlessly complements assembly and delivers functionally integrated parts from a single shot.
