Precision Turning, Milling &
Multi-Axis CNC Machining.
Donlouco supplies high-quality CNC-machined parts to OEMs across Ireland, the UK and Europe. All CNC work is done in-house at our own machining facility in Jiashan, China, managed from our head office in Cork. We specialise in complex, customer-specific components: forged and cast parts with secondary machining, and parts machined from solid, delivered ready-to-fit to your factory floor.
Owning the factory means we control scheduling, process, quality and cost directly, with no intermediary between your drawing and the machine.
Lead Times & Manufacturing Capacity.
High-volume capacity with flexible scheduling. Because the facility is ours, production slots are allocated to Donlouco customers first.
Weeks for initial samples and prototypes.
Weeks for volume production orders.
Including an average of 194K parts per month to a single hydraulics customer.
Just-in-time delivery available, with stock held on request.
Production flexibility:
We run both small-batch and high-volume work. Minimum orders for custom components are accommodated alongside annual volumes in the hundreds of thousands. Contact us to discuss your timeline.
High-Volume Precision Parts &
Turnkey Manufacturing Solutions.
3, 4 and 5-axis machining across ferrous and non-ferrous materials, producing complex, high-tolerance parts to European standards.
Multi-Axis CNC Machining
18 milling centres and 25 multi-axis lathes handle parts up to 1100 × 650 × 700mm and diameters to 1000mm, in carbon steel, stainless, cast iron, aluminium and high-grade alloys.
High-Volume Precision Manufacturing
Repeat production of hydraulic and industrial components for OEMs, with on-time shipment and consistent quality across every batch.
Dedicated Fixturing for Consistency
Custom-designed fixturing for each part guarantees repeatable accuracy and minimises defects in high-volume runs.
Custom Tooling & Engineering
Design and production of customer-specific tooling: gauges, jigs, fixtures, work holding and cutting tools for milling and grinding.
Materials we machine:
Carbon Steel Stainless Steel Cast Steel Cast Iron Aluminium High-Grade Alloys
From solid machined components to precision enclosures, across a broad range of sectors and part types.
CNC Machining,
Engineering Software & CAM.
We work with all standard 3D engineering software and CAM tools to generate machine programs in-house. STEP, SolidWorks and AutoCAD files are accepted, and our engineers can work from 2D drawings where needed. Full capability for customer-specific parts requiring complex fixtures and programming.
Our Own CNC Machining
Facility in Jiashan, China.
Donlouco has managed manufacturing in China for over 20 years.
