Sheet Metal Hemming: Types and Design Considerations
Choose a hem profile for sheet metal panels and enclosures, with guidance on return length, gaps, tooling clearance, and visible-edge finish.
Sheet Metal Box Design: Bends, Corners, and Lid Fit
A sheet metal box needs room for both the installed equipment and the path used to remove it. Review shell layouts, bend access, corner seams, and finished lid clearance before releasing the box and lid drawings together.
Sheet Metal Bend Relief: Design Guide for Brackets and Enclosures
A practical guide to sizing and placing bend reliefs in sheet metal brackets and enclosures. Learn how bend zones affect relief depth and what to check around mounting holes and corner joints.
Sheet Metal Bend Radius: Minimums by Material and Thickness
Compare bend radius guidance for aluminum and stainless steel, and see how tooling and radius changes affect part clearance and flat patterns.
Sheet Metal Assembly: Methods and Design Considerations
Plan sheet metal assemblies around each joint’s function, service needs, and installation sequence, then confirm the design with the manufacturer.
K-Factor in Sheet Metal: How It Changes a Bent Bracket’s Flat Pattern
Changing the K-factor changes a sheet metal bracket’s calculated flat length. Compare two settings in a worked example and check the calculation against actual forming conditions.
Sheet Metal Bending: How to Design Brackets and Panels
Plan bracket and panel geometry from mating faces, mounting alignment, and the finished envelope. The guide covers bend geometry, feature clearance, bend sequence, flat patterns, and drawing details for fabricator review.
How to Specify Machined Surface Roughness for CNC Parts: Ra, Rz, and Inspection Guide
Surface roughness affects sealing, sliding contact, appearance, and inspection cost. Learn how to specify Ra or Rz and verify CNC part surfaces.
Die Cast Tooling: Design Decisions Before Cutting Steel
Review how part geometry, fill, cooling, ejection, machining, and cavity configuration shape die cast tooling before toolmakers cut the steel. This guide shows buyers what to confirm with a die-casting partner.
How to Prepare a Technical Drawing for CNC Machining
Learn how to pair a 2D technical drawing with a 3D model and define the callouts, revisions, and inspection requirements for supplier review.
