A gauge variation or wrong grade changes springback and shortens die life. HIROKI's common materials include SPCC cold-rolled steel (comparable to ASTM A1008 CS), SPHC hot-rolled steel, SUS304 and SUS430 stainless (AISI 304 and 430), high-strength steel, S45C medium-carbon steel (comparable to AISI 1045), 5052 and 6061 aluminum, galvanized steel, copper, and phosphor bronze.<\/p>\n<h3><span class=\"n\">2.2<\/span>FAI: Validate the Die With a Full Layout<\/h3>\n<p><strong>FAI (First Article Inspection) is a full-dimension measurement of the first parts from a new die or production run, confirming tooling and process settings before volume production begins.<\/strong> In HIROKI's <a href=\"https:\/\/hirokimetal.com\/en\/solution\/\">custom stamping solution<\/a>, FAI is part of Stage 4, Sampling and Verification:<\/p>\n<ol>\n<li>Run the first die tryout (T1 sample) on the selected press.<\/li>\n<li>QA measures every dimension using a CMM, optical projector, and optical image sorting machine.<\/li>\n<li>Submit samples with the FAI report so you can run your own validation and fit testing.<\/li>\n<li>Fine-tune the die based on your feedback and inspection results until samples fully conform.<\/li>\n<\/ol>\n<h3><span class=\"n\">2.3<\/span>IPQC: Keep the Process in Control<\/h3>\n<p><strong>IPQC (In-Process Quality Control) means QC staff check parts at scheduled intervals during production to keep dimensions and appearance within control limits.<\/strong> Before launch, HIROKI establishes a standard operating procedure (SOP) that locks in production parameters. Its presses are equipped with stroke monitoring and load sensors, and together with periodic measurement and preventive die maintenance, this helps catch dimensional drift from die wear or feed misalignment early.<\/p>\n<h3><span class=\"n\">2.4<\/span>FQC: Verify the Part After Secondary Operations<\/h3>\n<p><strong>FQC (Final Quality Control) confirms dimensions, cosmetics, threads, and assembly function after stamping and all secondary operations are complete.<\/strong> Because deburring, grinding, tapping, finishing, and assembly all change the part, HIROKI matches the inspection method to each operation:<\/p>\n<ul>\n<li><strong><a href=\"https:\/\/hirokimetal.com\/en\/deburring\/\">Deburring<\/a><\/strong>: Visual and tactile checks, plus CCD optical inspection, optical projector, and CMM.<\/li>\n<li><strong><a href=\"https:\/\/hirokimetal.com\/en\/precision-grinding\/\">Surface grinding<\/a><\/strong>: Calipers, micrometers, CMM, and surface roughness measurement.<\/li>\n<li><strong><a href=\"https:\/\/hirokimetal.com\/en\/tapping\/\">Tapping<\/a><\/strong>: Go\/no-go thread gauges and the three-wire method.<\/li>\n<li><strong><a href=\"https:\/\/hirokimetal.com\/en\/riveting\/\">Riveting<\/a><\/strong>: Pull-out and torque testing for joint strength.<\/li>\n<li><strong><a href=\"https:\/\/hirokimetal.com\/en\/surface-finishing\/\">Surface finishing<\/a><\/strong>: Adhesion testing, gloss and color measurement, and comparison to approved samples.<\/li>\n<li><strong><a href=\"https:\/\/hirokimetal.com\/en\/parts-assembly\/\">Assembly<\/a><\/strong>: Calipers, depth gauges, concentricity checks, and torque meters, with mistake-proofing fixtures.<\/li>\n<\/ul>\n<h3><span class=\"n\">2.5<\/span>OQC: The Last Line of Defense<\/h3>\n<p><strong>OQC (Outgoing Quality Control) is the final inspection before packing, confirming that dimensions, appearance, and function meet your specification.<\/strong> HIROKI samples to AQL or to your specified sampling plan, and 100% inspection can be arranged for parts with special requirements. After release, parts are packed with rust-preventive and impact-resistant packaging suited to the product.<\/p>\n<h3><span class=\"n\">2.6<\/span>Lot Traceability: Find the Root Cause Fast<\/h3>\n<p><strong>Lot traceability links each lot's material, tooling, processing, and assembly records so a quality issue can be traced back to its source.<\/strong> HIROKI maintains lot traceability records in tapping that track material and tool usage, and uses barcode lot verification in assembly, with records traceable from material source through to assembly personnel.<\/p>\n<h3><span class=\"n\">2.7<\/span>QC Reports: Inspection You Can Verify<\/h3>\n<p><strong>A QC report documents the inspection results for a lot and ships with the parts as part of your receiving record.<\/strong> HIROKI can include a lot-level QC report with each shipment and provides FAI reports during new part development. If you need a specific report format or characteristics, include those requirements in your RFQ.<\/p>\n<\/section>\n<section class=\"hk-sec\" id=\"s3\" aria-labelledby=\"h-s3\">\n<h2 id=\"h-s3\"><span class=\"hk-hex\" aria-hidden=\"true\">03<\/span><span>What Inspection Equipment Does HIROKI Use?<\/span><\/h2>\n<div class=\"hk-answer\" data-speakable=\"answer\"><p><strong>HIROKI's inspection capability centers on a CMM, optical projector, and optical image sorting machine, supplemented by operation-specific gauges.<\/strong><\/p><\/div>\n<div class=\"hk-table-wrap\"><table class=\"hk-tbl\">\n<thead>\n<tr>\n<th scope=\"col\">Equipment \/ Gauge<\/th>\n<th scope=\"col\">Primary Use<\/th>\n<th scope=\"col\">Gate<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>CMM (coordinate measuring machine)<\/td>\n<td>Full-dimension and geometric measurement<\/td>\n<td>FAI, FQC<\/td>\n<\/tr>\n<tr>\n<td>Optical projector<\/td>\n<td>Profile and dimension comparison<\/td>\n<td>FAI, FQC<\/td>\n<\/tr>\n<tr>\n<td>Optical image sorting machine<\/td>\n<td>Vision-based dimensional and cosmetic sorting<\/td>\n<td>FAI, FQC<\/td>\n<\/tr>\n<tr>\n<td>CCD optical inspection<\/td>\n<td>Burr and edge condition<\/td>\n<td>FQC<\/td>\n<\/tr>\n<tr>\n<td>Calipers, micrometers, depth gauges<\/td>\n<td>General dimensional checks<\/td>\n<td>IQC, IPQC, FQC<\/td>\n<\/tr>\n<tr>\n<td>Surface roughness measurement<\/td>\n<td>Ground surface condition<\/td>\n<td>FQC<\/td>\n<\/tr>\n<tr>\n<td>Go\/no-go gauges, three-wire method<\/td>\n<td>Thread verification<\/td>\n<td>FQC<\/td>\n<\/tr>\n<tr>\n<td>Pull-out and torque testing<\/td>\n<td>Rivet and fastener strength<\/td>\n<td>FQC<\/td>\n<\/tr>\n<tr>\n<td>Gloss meter, color measurement<\/td>\n<td>Finish appearance<\/td>\n<td>FQC<\/td>\n<\/tr>\n<tr>\n<td>Stroke monitoring and load sensors<\/td>\n<td>Press process monitoring<\/td>\n<td>IPQC<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/div>\n<\/section>\n<section class=\"hk-sec\" id=\"s4\" aria-labelledby=\"h-s4\">\n<h2 id=\"h-s4\"><span class=\"hk-hex\" aria-hidden=\"true\">04<\/span><span>What Should Buyers Ask When Auditing a Stamping Supplier's Quality?<\/span><\/h2>\n<div class=\"hk-answer\" data-speakable=\"answer\"><p><strong>When qualifying a stamping supplier, confirm five things: complete inspection gates, measurement methods matched to critical dimensions, a defined sampling basis, FAI and lot-level QC reports, and lot traceability.<\/strong><\/p><\/div>\n<ol>\n<li><strong>Inspection gates<\/strong>: Are incoming, first article, in-process, final, and outgoing inspection all covered?<\/li>\n<li><strong>Measurement capability<\/strong>: What equipment measures your critical dimensions, CMM or optical projector?<\/li>\n<li><strong>Sampling basis<\/strong>: AQL or customer-specified?
