Packing and shipping precision parts without damage
Separate parts, protect finishes, align labels with revision and lot traceability.
Welding tolerances vs machined tolerances: set expectations
Welding moves material; align datums and post-weld machining when precision must be recovered.
Plating and coatings: a buyer’s overview
Pick finishes for corrosion, wear, and cosmetics; cite standards and watch dimensional build-up.
Stamping vs CNC for brackets: a decision framework
Volume, tooling NRE, and change frequency decide stamping vs CNC; hybrids are common.
Anodizing basics for aluminum machined components
Match anodize type to wear vs cosmetics; plan masking and dimensional stack for thick coatings.
Deburring and edge breaks: what to put on the drawing
Match deburr notes to sealing, safety, and cosmetic requirements—avoid vague hand-waving.
Threading and taps: practical notes for CNC parts
Clarify thread class, depth, and blind-hole drill depth to avoid scrap and rework.
Inside corners and radii: small details that drive DFM
Tool radius defines pocket corners; relax radii where possible to save cost and improve finish.
Aluminum 6061 vs 7075: choosing for machined parts
6061 balances machinability and corrosion; 7075 trades strength for care in finish and joining.
