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.

Pre-assembly of plastic components

Precisely aligned with production processes.

Assembly of components and assemblies

Multiple components – one coordinated process.

Integration of purchased parts

Inserting, joining, screwing or clipping.

Organized close to production

Assembly in sync with production or as a separate process.

Typical assembly steps

Flexible combinations – depending on component and requirements.

Our assembly services adapt to your product. The focus is on reliability, repeatability and clean processes.

Assembly scope and inspection steps are individually defined.

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.

Injection-moulded plastic part

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.

Assembly of plastic components

Packaging & further processing

Assembled, inspected, packaged.

After assembly, we can also handle packaging if required – coordinated with logistics, transport and further processing at the customer.

Frequently asked questions

FAQ about assembly of plastic components and assemblies

From simple pre-assembly of individual components to assembly manufacturing with integrated components – depending on the product and production volume.

Yes. Assembly can be organized directly after production or as a separate, coordinated process.

Yes. Purchased parts can be integrated, joined or assembled according to clearly defined processes.

Through work instructions, inspection plans and in-process inspections – adapted to the respective assembly.

From the pre-assembly of individual plastic parts, through joining, clipping and screwing, to the complete assembly – including purchased parts, functional testing and packaging – all carried out immediately after injection moulding.
