Comprehensive Mold Solutions
Final Assembly & Packaging
Components, sub-assemblies and finished goods assembled, tested and packed to your specification, ready for your market.
From component supplier to finished product
Once the parts are right, someone still has to put them together, test them and get them into packaging that survives the journey. For many customers this is the least glamorous part of the project and the one that creates the most delay.
We assemble, test and pack to your work instruction, hold the finished stock and ship on your release schedule.
- Assembly to your drawing, BOM and work instruction
- Functional and leak testing as specified
- Retail or industrial packaging, printed to your artwork
- Finished-goods stockholding and scheduled shipment
Assembly and packing services

Sub-assembly
Multi-part assemblies with inserts, springs, seals and fasteners, built to a documented sequence.

Testing and verification
Functional checks, leak tests, electrical safety tests and packaging integrity checks.

Packaging
Cartons, inserts, bags and retail packs printed to your specification, with barcodes and labels.

Stockholding and shipping
Finished goods held in our warehouse and shipped on your release plan, with export documentation.
What we need from you
| Input | Why |
|---|---|
| Assembly drawing and BOM | Defines the sequence and the components, including their source |
| Work instruction and test criteria | Sets the checks and the pass/fail limits per unit |
| Packaging artwork and specification | Printing, carton grade, labelling and barcode content |
| Release schedule | Lets us plan stockholding instead of shipping everything at once |
How an assembly programme runs
01
Specification review
We walk through the drawing, BOM and test criteria and flag anything ambiguous before quoting.
02
Line and fixture setup
Assembly fixtures, test rigs and packaging stations set up and validated.
03
Pilot run
A small batch assembled, tested and packed for your approval.
04
Production
Volume assembly with documented in-process checks and a defined sampling plan.
05
Packing and dispatch
Finished goods packed, labelled and shipped against your release schedule.
Frequently asked questions
Can you source the components as well as assemble them?
Yes. We can take responsibility for the complete package — moulded parts, purchased components, assembly and packing — which reduces the number of suppliers you have to manage.
How is quality controlled on an assembly line?
Each unit passes the specified checks, with a documented sampling plan and traceability back to the batch. Assembly defects are logged so the same fault cannot repeat silently.
Can you hold stock and ship against a forecast?
Yes. Stockholding with scheduled release is usually cheaper than shipping in one lot, and it reduces the risk of holding a large returnable balance at your end.
Do you handle custom packaging?
We do — printed cartons, foam or plastic inserts, retail-ready packs and anything needed to get the product to the shelf or the assembly line undamaged.
