Tridan Engineering

What Tridan Engineering does

Tridan Engineering Ltd is a UK-based precision CNC machining and mechanical assembly subcontractor headquartered in Clacton-On-Sea, Essex. Founded in 1968 and wholly owned by Langham Industries (acquired 1989), the company operates from a 26,000 square foot facility with 60-63 employees, 20 CNC machining centres, and doubled CMM inspection capacity on a two-shift system. The company's core offering spans 5-axis CNC milling (Mazak Variaxis i500/i600/i700), CNC turning, sliding head machining (Star ST-38, SR-20JII), mechanical assembly, and CAD/CAM programming — sold as a total outsource partnership covering design-for-manufacture through to certified finished assemblies.

Tridan serves blue-chip customers across seven regulated sectors: aerospace, defence, medical, specialist automotive, marine, food manufacturing, and communication. Customer relationships are deep and operationally embedded — evidenced by weekly DFM meetings with MBDA, Kanban/JIT supply to a leading US biomedical OEM at ~5,000 parts/month, and exclusive production partnership with Bruntons Propellers for the Autoprop marine propeller (Queen's Award for Technological Achievement). AS/EN9100 (since 2008), ISO 14001 (since 2011), JOSCAR registration (since September 2020), and Cyber Essentials Plus certifications form the regulatory backbone enabling defence and aerospace prime supply chain access.

The business model is enterprise contract manufacturing: quote-based pricing per project/batch with no public price list, distributed exclusively through direct field sales (Sales Director, Sales & Marketing Engineer, Sales Administrator). GTM combines relationship-driven preferred-supplier status, JOSCAR-enabled defence procurement, and inbound enquiry via website and case studies. Revenue streams include contract CNC machining (primary), sub-assembly services, and a smaller proprietary product line (Autoprop marine propellers). Recent capital expansion — four new machining centres in the past year plus three additional 2026 installs — signals active capacity scaling.

Revenue model

1. Contract Precision CNC Machining: Tridan Engineering generates revenue primarily through billable CNC precision machining services rendered under contract to blue-chip organisations. Revenue is project/batch-based, with work spanning small-batch prototyping through to high-volume production runs across CNC milling, turning, and sliding head operations. Components are machined from raw materials (metals, alloys, exotic materials) through to finished parts, with pricing driven by part complexity, material, tolerance requirements, batch size, and machining time. The company also manufactures its own marine propellers (Autoprop, folding and feathering propellers) as a proprietary product line, adding a product revenue stream alongside its contract manufacturing services.
2. Sub-Assembly and Finished Assembly Services: Mechanical assembly services including fitting of helicoils, clinch nuts, swaged bearings, wire locking, and full assembly to customer requirements. Assembly services are charged as part of the overall component delivery contract or as standalone services for customers requiring finished sub-assemblies.
3. Proprietary Marine Propeller Products: Tridan produces its own range of folding and feathering marine propellers (Autoprop) designed in-house. This product line is sold directly to marine customers and through the group's Bruntons Propellers distribution network, representing a product revenue stream distinct from the sub-contract machining business.
