Stress-Free from First Enquiry to Final Delivery.
Partnering with Donlouco removes the frustrations of overseas sourcing. Here's how a typical project works:
Enquiry & Design Review
Send us your drawings, specifications or samples. Our engineers review requirements and advise on the best process and materials.
Quoting & Approval
We provide a detailed, competitive quote. Once approved, tooling is designed, managed and approved before any production begins.
Production & Quality Control
CNC parts are machined in our own facility; forgings are produced by approved partners. Every part is inspected at production and again before shipping, with dimensional reports and material certs.
Delivery to Your Door
Sea or air freight managed by Donlouco, including customs clearance. Parts delivered plug-and-play ready to your facility in Ireland, the UK or Europe.
The Gap Between Your Drawing and What Gets Made. We Close It.
Established in 2002 and based in Cork, Donlouco owns and operates its own CNC machining facility in Jiashan, China. There is no intermediary: the engineers who read your drawing in Ireland are the same company that runs the machine in China.
That is how we communicate the requirements that never make it onto a drawing, and why every part arrives to the standard you specified.
- Head office in Cork, Ireland. All customer relationships managed locally.
- Our own CNC machining facility in Jiashan, staffed by Donlouco engineers and inspectors.
- Oracle-based EMS providing real-time visibility across both locations.
- Turnkey service from design through to delivery at your door.
