Assembling custom sheet metal chassis

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.
Custom aluminum enclosure brackets

Sheet Metal Fabrication Cost: What Changes the Price of a Custom Enclosure?

Material use, bend complexity, welded seams, finishing, and order quantity explain why custom enclosure quotes differ.
Die casting vs sand casting processes

Investment Casting vs Die Casting: How to Choose for Aluminum Parts

Compare die casting and investment casting for aluminum housings, with guidance on internal geometry, sealing requirements, production volume, tooling cost, and preparing comparable process quotes.
CNC laser cutting sheet metal with sparks

Laser Kerf Size: How to Measure It in Sheet Metal for Tab-and-Slot Fit

Measure laser kerf on test cuts and keep CAM compensation separate from assembly clearance. See how sheet thickness, cut edge taper, and finishing affect tab-and-slot fit.
Worker bending sheet metal on a press brake

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.
Machined titanium structural bracket

What Is Grade 5 Titanium? A Material Selection Guide for CNC Parts

Grade 5 titanium (Ti-6Al-4V) combines high strength with low weight, but stiffness and machining costs affect material selection. This article explains the alloy's properties and what engineering teams need to consider when specifying precision CNC parts.
CNC milling vs turning machining comparison

Milling vs Turning: Choosing a Machining Route for Parts with Round and Flat Features

See how functional diameters, flats, and pockets point to a turning-led or milling-led route, and what engineers should confirm about datums, setups, and inspection.
Precision sheet metal brackets and bending

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.
5052 vs 6061 aluminum sheet metal parts

5052 Aluminum vs. 6061: Which Alloy Should Engineers Specify for Bent Sheet Metal Parts?

For bent covers, panels, and brackets, compare 5052-H32 with 6061-T6 and identify the material and bend details to confirm in the RFQ.
Delrin vs nylon CNC machined parts

Delrin vs Nylon: Which Is Better for CNC Machined Parts?

Choose a material for gears, bushings, rollers, and sliding parts by matching the grade to fit stability, loads, wear, and service conditions.
Soft machining supplier quotation review

How to Compare Soft Machining Costs and Supplier Quotes

Compare soft machining quotes against one manufacturing route. This guide helps sourcing teams identify scope gaps and clarify cost, schedule, inspection, and rework responsibilities before issuing a purchase order.
Precision sheet metal enclosure

Sheet Metal Gauge Chart: Steel, Stainless Steel, and Aluminum Thickness

Gauge numbers correspond to different nominal thicknesses for standard steel, stainless steel, and aluminum. This chart lists inch and millimeter values and explains how material-specific thickness affects bending, assembly fit, and drawing or RFQ callouts.
