Pre-assembly and assembly manufacturing directly at the injection molder.
Plastic assembly of components and sub-assemblies.
We assemble plastic components, assemblies and components directly after injection molding production. From simple pre-assemblies to coordinated assemblies – efficiently organized, clearly documented and integrated into existing production processes.
What we mean by plastic assembly
More than just putting parts together.
For us, assembly means simplifying processes, reducing interfaces and organizing workflows efficiently. Whether simple pre-assembly or complete assemblies – everything is clearly defined, documented and integrated into your production logic.
Why assembly directly at HERGIL?
Fewer interfaces. More control.
When production and assembly are combined both spatially and organizationally, clear advantages arise: shorter distances, less coordination effort and a consistent view on quality and delivery schedules.

Kunststoff Montage aus einer Hand – vom Bauteil zur fertigen Baugruppe
The biggest advantage of our plastics assembly process is its proximity to our own production facilities: as the components come straight from the injection moulding line at HERGIL, we assemble them immediately, without any detours, intermediate transport or additional interfaces. This saves time, reduces the potential for errors and keeps responsibility and quality in one place.
Depending on the product, we combine various joining and assembly methods – from screwing and clipping, through the insertion of seals and threaded inserts, to complete assemblies with integrated purchased parts. Every step is documented via work instructions and inspection plans and is traceable on a job-by-job basis – with the same care and attention to detail that has characterised our manufacturing for over 75 years.
Typical applications for our plastic assembly services can be found wherever components need to work together reliably: in microelectronics, the automotive supply chain, building services and industry. Whether it’s an assembled functional unit, a tested sub-assembly or a set packed ready for dispatch – you receive a ready-to-install solution from a single source.
Quality & organization
Assembly with clear standards.
In assembly, we also work with defined procedures, inspections and documentation – adapted to the complexity and application of the assembly.
