Guides and articles

Engineering guideHow Cams Drive Transfer Dies: Gripping, Feeding and ClearanceA transfer system moves a workpiece from one die station to the next. When it grips, how high it lifts, how far it travels and when it withdraws all affect the next press operation. Start with these handoffs to understand a cam-driven mechanism.Product selectionChoosing Coasters for Bars: Beer, Wine, Whiskey and CocktailsA practical guide for bar operators, hospitality buyers and drinks brands comparing coaster designs for different glasses and repeated service.Product selectionChoosing Coasters for Coffee, Tea and Everyday UseChoose a coaster for the cup and surface you use every day, whether on a café table, a dining table or an office desk.Troubleshooting guideMetal Stamping Defects: Identify, Investigate and VerifyUse the defect's location and first appearance to choose useful checks, then verify that a correction improves the whole part. This guide covers both cutting and forming defects.Die designHole Flanging Die Design: Why Collars Spring Back or StickA collar can look correct with the die closed and still change size or resist stripping when the tool opens. Review how the material deforms, where the tools contact it and how the finished part leaves the die.Illustrated stamping guide18 Metal Stamping Terms Explained Through Material DeformationA hole, a raised tongue and a drawn cup can start from the same flat sheet, but they are made by different material movements. These six original illustrations explain what 18 common workshop terms mean and what happens to the metal.Stainless steel enclosure guideWhich Stainless Steel Grade Should You Use for an Enclosure?For most general-purpose sheet metal enclosures, 304 is the usual evaluation starting point. Consider 316 or 316L when chlorides, repeated wet cleaning or persistent moisture increase localized-corrosion risk, and use an L grade when welding makes sensitization control relevant. Other stainless families require a defined reason and fabrication review.Aluminum material guideAluminum Alloy Series 1xxx–8xxx: How to Choose Grade and TemperThe 1xxx–8xxx series are chemistry families within the four-digit wrought aluminum designation system, not a ranking from weak to strong. Use the series to form a shortlist, then approve the complete alloy, temper, product form, thickness, manufacturing route and governing material standard together.Sheet metal process guideSheet Metal Fabrication Process: How We Take Your Drawing to Final InspectionAfter you send us a sheet metal drawing, three questions usually matter first: can the part be made as required, what is still missing for quotation, and what happens next? We review the drawing, model, material, hardware and finish requirements, then return one consolidated list of questions. Once we agree what the quotation and production will follow, we prepare material and flat-pattern data, plan blanking, deburring, bending, press-in hardware, joining and simple assembly within the quoted scope, coordinate external surface finishing, and finally inspect and package the part to the drawing.Steel heat treatment guideAnnealing, Normalizing, Quenching and Tempering: A Steel Heat Treatment GuideThe four familiar heat-treatment operations are not interchangeable, and tempering usually follows quench hardening rather than competing with it. Start with the steel grade, section, starting condition, required properties and dimensional risk before selecting or approving a cycle.Welding and assembly guideSheet Metal Welding Distortion and Material Changes: An Enclosure DFM GuideTreat heat, joint geometry, alloy condition and inspection as one welded-enclosure DFM problem. Define the joint, datums, surface condition and buyer-owned validation before the supplier selects fixtures, sequence or process details.DFM and RFQ guidePlating Cost in the RFQ: What to Write Before You Compare QuotesShops can estimate deposited metal from plated area, thickness and density. That is one line of the quote, not the whole price. Write metal, min thickness, faces, rack or barrel, masking and inclusions before you compare numbers.DFM and RFQ guideCopper Passivation, Sealing and Salt Spray: What to Write on the RFQPassivation and sealing can slow copper tarnish. Whether a part passes 96-hour salt spray depends on the alloy, cleanliness, finish route, contact pads and the fail rule on the drawing. Put those notes in the RFQ before you compare quotes.Production guideMetal Stamping Production Process: From Coil to Finished PartsFollow the material through a typical stamping route and see what each stage produces, what should be checked, and when the part is ready to move on.Inspection guidePCB Shielding Can Flatness and Appearance InspectionA shielding can may look flat yet leave a solder tab lifted. Learn which surfaces to check, how to avoid distorting thin parts during measurement, and when feeler gauges, 3D scanning or vision inspection are useful.Design and RFQ guidePCB EMI/RF Shielding Can Design and RFQ GuideA shielding can is only one part of an EMC strategy. Use this guide to define its construction, board interface, material, finish, openings, edge condition, assembly route and validation plan before requesting tooling or production pricing.DFM and RFQ guideStamped Copper Busbars and Battery Terminals: DFM and RFQ GuideA manufacturable copper busbar or battery terminal RFQ defines the buyer-specified copper grade and temper, thickness, formed geometry, contact zones, burr direction, plating, joining interfaces, inspection and packaging before tooling is quoted.Thermal hardware DFM guideStamped Heat Spreaders, Thermal Plates and Shims: DFM and RFQ GuideA manufacturable heat spreader RFQ defines the part geometry, material, thickness, contact zones, flatness, finish, inspection and packaging without asking the metal part supplier to guess the complete thermal system. Use this guide to separate part-making requirements from system-level thermal validation.Design guideSheet Metal Bending DFM Guide: K-Factor, Bend Radius and Hole-to-Bend DistanceA reliable flat pattern depends on more than a CAD bend command. Use this guide to define the neutral axis, radius, flange and feature clearances for press-brake parts, then confirm the real bend data with the fabricator before release.Cost and lead time guideCustom Sheet Metal Enclosure Cost Guide: What Drives Price and Lead TimeA custom enclosure price is the result of its material, geometry, process route, quantity, hardware, finish and approval requirements. Use this guide to understand quote differences and prepare an RFQ that gives suppliers a consistent basis for review.Engineering guideProgressive Die Stamping Design, Volume and Tooling GuideA buyer-focused guide to preparing a stamped part for progressive tooling, from feature and strip decisions through station planning, volume assumptions, die trials and production release.Production guidePrototype to Production Metal Stamping: 8-Stage Release GuidePrototype-to-production metal stamping should pass eight controlled gates: validation brief, early sample, design freeze, die trials, FAI, buyer-required PPAP, pilot run and production release. Each gate needs defined inputs, evidence and an approval owner.Hardware design guidePEM Inserts, Rivet Nuts and Weld Nuts for Sheet Metal EnclosuresChoose enclosure hardware by sheet material, thickness, assembly access, service load, finish sequence and inspection method, then show every insert, stud and masked contact area clearly in the RFQ drawing package.DFM and RFQ guideElectronic Stamped Components: DFM and RFQ GuideA useful electronic stamped components RFQ defines the part function, drawing revision, material, critical fit, burr direction, contact surfaces, finish, volume, sample approval and packaging before tooling or production is quoted.RFQ guideBattery Energy Storage Enclosure RFQ Guide for OEM BuyersA useful battery energy storage enclosure RFQ explains the battery pack or ESS cabinet purpose, mechanical layout, material, finish, ventilation, grounding, cable openings and sample approval plan before pricing starts.RFQ guideMetal Parts Surface Finish RFQ Guide for OEM BuyersUse this surface finish RFQ guide to specify metal part materials, visible faces, finish options, samples, inspection notes and compliance expectations before quote review.RFQ guideSheet Metal Fabrication RFQ Checklist for OEM EnclosuresUse this sheet metal fabrication RFQ checklist to align enclosure drawings, materials, finishes, inspection notes and production expectations before quote review.Engineering guideMetal Stamping DFM Preflight Before Tooling QuoteBefore committing to a stamping die, turn drawing questions into clear decisions about the process, price and sample checks.

RFQ Preparation01

Prepare clearer RFQs before drawing review

Use these guides to organize the details engineering needs before quote review. Clear drawings, material notes, finishing requirements and quantity targets make the first response more useful.

  • Prepare material, thickness, finish, tolerance, volume and inspection notes before quote.
  • Understand which details change tooling cost, sample lead time and production repeatability.
  • Use the guides to reduce back-and-forth when engineering reviews your drawing package.
Manufacturing Route02

Compare process, material and finish risks early

A quote is easier to trust when the manufacturing route is clear. These guides help sourcing and engineering teams compare stamping, fabrication, tooling, material and finishing decisions before committing to samples or dies.

  • DFM guidance helps engineering teams identify risky features before tooling.
  • Material and finishing guides help procurement teams avoid hidden quote assumptions.
  • Process and tooling guides make sample approval and production release easier to understand.
Next Step03

Move from guide reading to drawing review

When a guide answers the first question, the next practical step is to share drawings, samples or early requirements for project-specific review.

  • Compare related stamping, tooling, enclosure and finishing capabilities in one place.
  • Review answers to common buyer questions about RFQs, materials, processes and finishes.
  • Start the RFQ with drawings, material, thickness, finish and target quantity.
Buyer questions

Common buyer questions

Have a question about your part? Leave a message and a reply email.

What should buyers read before sending an RFQ?

The RFQ checklist, production process, material selection and finishing guides help buyers prepare drawings and requirements before quote review.

Do these resources replace engineering review?

No. The resources help buyers prepare better information, but drawings, material, finish, tolerance and quantity still need project-specific engineering review.

Which guide is best for a new stamping project?

Start with the RFQ checklist and process guide, then review material and finishing pages if the drawing already includes those requirements.

Can I send drawings if I am not sure about the process?

Yes. Early drawings, photos or samples can be reviewed to decide whether the part fits stamping, fabrication, tooling development or another route.
