Engineering Checklists & PDF Downloads
Practical, printable checklists and standard specification sheets designed to streamline CAD drawing releases, DFM sign-offs, and procurement RFQ preparation.
Standard Checklists & Reference Cards
Direct-download reference sheets formatted for shop-floor printing or engineering CAD workstation reference.
Sheet Metal DFM Pre-Release Checklist
A 20-point verification checklist for CAD designers checking minimum bend radius, hole-to-edge clearances, bend relief cutouts, and grain direction.
RFQ Drawing Preparation & CAD Package Checklist
Guidelines on what CAD formats to export (STEP, DXF, PDF), required title block annotations, critical tolerance callouts, and finish callouts to ensure 24-hr quoting.
Surface Roughness (Ra/Rz/N-Grade) Conversion Chart
A quick-reference visual engineering wall chart mapping microinches (µin), micrometers (µm Ra/Rz), ISO N grades, and typical achievable finishes across milling, grinding, and polishing.
Industrial Coating System Selection Matrix
Comparative durability matrix matching environmental corrosivity categories (ISO 12944 C1 to C5) with optimal primer, intermediate, and topcoat systems (epoxy, polyurethane, polyester powder).
Visual Weld Inspection & Acceptance Guide
Comprehensive guide to visual weld defect criteria based on AWS D1.1 and ISO 5817 Level B/C: allowable undercut, porosity limits, throat thickness calculations, and fillet profile gauges.
Machine Frame Structural Fabrication Guidelines
Engineering guidance for designing welded steel structural automation frames: section modulus selection, gusset placement, weld sequencing, and post-weld machining pads.
