Technical procurement from batch size 1
In energy technology, designers and maintenance engineers regularly need components that aren’t available off the shelf — high-strength custom bolts for flange connections, shafts and pins for generators and drives, connecting and wear parts made from temperature- and corrosion-resistant materials. That’s exactly what we’re here for.
We supply power plant and plant engineering companies, manufacturers of turbines, generators and gearboxes, as well as wind and hydropower operators — from first-sample delivery for a prototype to ongoing series supply of wear and spare parts.
Material certificates 2.1, 2.2 or 3.1 to EN 10204 — standard, not a surcharge. Full traceability via heat number.
Typical quantities
1 – 5,000
Main processes
CNC turning, CNC milling
Standard materials
42CrMo4, 1.4571, CuSn8
Standard documentation
EN 10204 3.1
Standard lead time
3 – 6 weeks
High-strength custom bolts for flange connections, strength class up to 12.9, with documented material.
For generators, gearboxes and drives, with fits and functional dimensions.
Bearings and turned parts made from stainless steel, bronze and temperature-resistant special materials.
Mounts, holders and complex housing components for turbines, generators and switchgear.
YOUR ADVANTAGE
Send us your drawing, STEP file or sample part – we check feasibility, material and surface finish, then get back to you with a reliable quotation including delivery date.
On request, we provide first-off samples with an inspection report before series production starts. This ensures you’re on the safe side – even for critical functional dimensions and fits.
Cases
A
120 flange bolts M30x160 made from 25CrMo4, quenched and tempered to grade 10.9, with material certificate 3.1. Lead time 4 weeks, first sample after 14 days.
B
Complete shaft with multiple steps, machined keyways, induction-hardened bearing seats. Batch size 12 — produced economically on a multi-axis turning center.
C
Bushings made from CuSn8 in 8 different sizes, 50 pieces each, with slotted lubrication grooves. Standardized via master order.
Other Industries
Send us the drawing or key specifications. We will generally respond the same
business day with an initial technical assessment.
