CNC capabilities
Housings, shafts, gears, brackets, fixtures, impellers and robot components. BSD reviews the material, geometry and critical features to select a practical process.
Machining capabilities
- Milling
- 3-, 4- and 5-axis; 5+2-axis capability
- Turning
- Shafts, pins and cylindrical components
- Order volume
- 1-piece prototypes, low-volume and repeat production
- Precision
- Down to ±0.01 mm under suitable conditions; confirmed after technical review
Materials & finishing
- Metals
- Aluminum, stainless steel, brass, copper, tool steel
- Surface finish
- Anodizing, plating, polishing, sandblasting, powder coating
- Engineering
- Material selection, DFM review and process optimization
- Sample timing
- Typically 7–15 days, depending on complexity, materials and finishing
Exact tolerances, process, price and delivery schedule are evaluated against your project requirements.
Quality inspection
CMM measurement checks critical dimensions and complex geometries against your requirements.
- Material and in-process checks
- First Article Inspection before batch production
- Dimensional measurement and final inspection
Mark critical dimensions on your drawing so the inspection plan reflects what matters to your assembly.

Germany / Precision & design validation
A sample that earned the buyer’s confidence.
Sample-first validation
The challengePrevious supplier parts had been rejected for insufficient precision. The buyer needed evidence that the new parts would fit and perform.
Our approachBSD supplied an initial sample for measurement and assembly trials, then worked with the design team on insulation-panel improvements.
Result
The first sample passed the customer’s validation; joint prototype development also addressed heat leakage at assembly gaps.

A better manufacturing route. A lower unit cost.
$13.80 → $5.83
The challengeAn order for 2,000 aluminum parts was originally specified for full CNC machining, with low material utilization and a quoted unit cost of $13.80.
Our approachBSD proposed extrusion, cold drawing, sawing, turning and black anodizing for this particular component.
Result
The reported unit cost fell to $5.83. The customer subsequently increased the order to 10,000 units.

From a requirement to 100 finished cabinets.
100 sets / no initial drawing
The challengeThe customer had an application and quantity, but no completed manufacturing drawing.
Our approachEngineering and design teams reviewed structure, dimensions, materials and appearance through several discussions. The customer approved the final drawing before production.
Result
100 cabinets were produced and delivered. The company reports a repeat order after the customer received and inspected the products.

90 g / optimized part weight
The challengeA volume-production project needed lower part weight and a suitable process beyond CNC machining.
Our approachBSD evaluated metal injection molding and moved the remaining 3,000 units of a 5,000-unit pilot order to MIM after validation.
Result
The case reports a weight of about 90 g per unit, around one-quarter of the original machined part. It illustrates engineering support across manufacturing processes.

18 models. One coordinated production plan.
18 models / 480 units per month
The challenge18 cabinet models required frequent changeovers, deformation control and IP54 sealing.
Our approachBSD coordinated cutting, bending, welding, coating and model-specific inspections.
Result
The published project reports 480 units per month and a 99.2% first-pass yield. These are results for this sheet-metal project.
