Busbars and conductors
Busbar weight, resistance and current
Mass, surface area, DC resistance, voltage drop and an indicative current rating for flat, round, tube and laminated bars.
Outputs: PDF, Excel, CSV, share linkOpen tool →Busbar drawing generator
Build a bent or twisted busbar, see DFM checks against each rule, then download a formed drawing, flat pattern and solid model.
Outputs: A3 drawing PDF, DXF flat pattern, STEP solidOpen tool →Material grade cross-referenceNew
Copper, brass and aluminium grades across EN, UNS and ASTM, JIS and IS, with density, conductivity and typical use.
Outputs: CSV, share linkOpen tool →Drawings, tolerances and inspection
Drawing RFQ checkNew
Upload a drawing and see what a supplier will ask before they can quote: grade, finish, tolerances, revision and quantity.
Outputs: checklist PDF, send to QumekOpen tool →General tolerance calculator
ISO 2768, ISO 22081, ISO 286 fits, ISO 8062 castings, ISO 13920 weldments, DIN 6930 stampings and ISO 20457 mouldings.
Outputs: callout text, inspection plan CSVOpen tool →First article inspection report
Balloon a PDF drawing, enter tolerances as written, record measurements and export an AS9102-style report.
Outputs: PDF, Excel workbookOpen tool →Sourcing
Landed cost calculator
Compare up to three origins with freight, duty, VAT cash flow, inventory and quality cost, each rate dated and sourced.
Outputs: one-page sourcing case PDF, ExcelOpen tool →Tooling break-even
No-tooling prototype route against a progressive die: the volume at which tooling pays back.
