T1 (first steel trial) typically confirms that the mold opens, fills, and ejects without mechanical problems, and may include basic visual checks. FAI is a formal, documented, feature-by-feature dimensional and material verification. A mold can pass T1 but fail FAI due to dimensional deviations that are not visible to the eye\u2014such as a wall thickness 0.12 mm outside tolerance.<\/p>\n<\/div>\n<h2>\u0130lk Numune Muayenesi Ad\u0131m Ad\u0131m Nas\u0131l Yap\u0131l\u0131r?<\/h2>\n<p>FAI follows a defined sequence that ensures all verification activities are completed before any data is recorded. Shortcuts\u2014such as measuring parts before they have fully cooled to ambient temperature, or measuring only one of the three sample parts\u2014invalidate the inspection and typically result in customer rejection of the FAIR.<\/p>\n<p>Step 1 is part conditioning. Injection-molded parts must be conditioned at 23\u00b0C \u00b12\u00b0C for a minimum of 4 hours (per ASTM D618) before measurement. Parts measured immediately after molding will read differently due to residual heat and stress relaxation. Step 2 is drawing review: the quality engineer balloons every dimension and assigns a unique ID. Step 3 is CMM programming or fixture setup for measurement. Step 4 is measurement of all three to five sample parts, with actual values recorded. Step 5 is material and process record archiving.<\/p>\n<p>Step 6 is Cpk analysis for critical features. For any dimension with a critical-to-function tolerance, we calculate the process capability index (Cpk). The accepted minimum is Cpk \u2265 1.33, which corresponds to a process running at least 4 sigma from its nearest tolerance limit. Features below this threshold require mold rework before FAI can be approved. Step 7 is customer submission and sign-off. The complete FAIR package is transmitted to the customer; written approval is required before production begins.<\/p>\n<div class=\"claim claim-true\" style=\"background-color: #eff7ef; border-color: #eff7ef; color: #5a8a5a;\">\n<p><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"20\" height=\"20\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"#16a34a\" stroke-width=\"2\"><path d=\"M9 16.17L4.83 12l-1.42 1.41L9 19 21 7l-1.41-1.41z\"\/><\/svg><b>&#8220;Parts must be conditioned at 23\u00b0C for at least 4 hours before FAI measurement.&#8221;<\/b><span class=\"claim-true-or-false\">Do\u011fru<\/span><\/p>\n<p class=\"claim-explanation\">ASTM D618 specifies that thermoplastic parts must be conditioned at 23\u00b0C \u00b12\u00b0C and 50% \u00b15% relative humidity for a minimum of 4 hours before dimensional measurement.

A complex 8-cavity medical device component with 120+ balloons, GD&#038;T callouts, and material traceability requirements may take 5\u20137 working days.<\/p>\n<p>The biggest time drivers are CMM program development (4\u201316 hours for a new program) and customer-required reports with statistical analysis (Cpk calculations for 20\u201330 critical features). Customers who provide CAD models and a pre-ballooned drawing dramatically reduce FAI turnaround time. Those who only supply a 2D PDF drawing require our team to model the nominal geometry before CMM programming can begin.<\/p>\n<p>At ZetarMold, we build FAI time into every project schedule at the mold qualification stage. Customers who treat FAI as an afterthought\u2014requesting it only after they expected parts to ship\u2014create delays. Our standard lead time commitment: T1 trial parts within 4 weeks of mold approval; FAI report within 5 business days of T1 parts being conditioned; production release within 3 business days of customer FAIR approval.<\/p>\n<h2>Bir Par\u00e7a \u0130lk Numune Muayenesinden Ge\u00e7mezse Ne Olur?<\/h2>\n<p>FAI failure means that one or more measured features fall outside their drawing tolerance on the first-article sample parts. The response depends on the nature and magnitude of the deviation. Minor deviations (within 20% of the tolerance band outside nominal) may be addressed through process adjustment\u2014changing pack pressure, cooling time, or melt temperature\u2014without touching the mold steel. These are documented as process NCRs and re-measured on a fresh set of conditioned parts.<\/p>\n<p>Dimensional deviations that exceed process adjustment capability require mold steel modification. Steel removal (cutting more material) is straightforward; steel addition (welding or insert replacement) is more expensive and time-consuming. In either case, a partial re-FAI is performed: only the affected features and any dimensions that could have been influenced by the modification need to be re-measured. A full re-FAI is required if the modification involved significant steel removal affecting multiple cavity regions.<\/p>\n<p>Some customers allow a Deviation Approval (also called a concession or waiver) for features that are marginally out of tolerance but demonstrably do not affect function or assembly. This requires engineering sign-off from the customer and a defined review timeline. Deviations are never permanent; the mold must be corrected before the next tool change or at the next scheduled maintenance window. In our factory, we track all open deviations in our ERP system and flag them for action at each mold service interval.<\/p>\n<h2>Enjeksiyon Kal\u0131plamada \u0130lk \u00dcr\u00fcn Muayenesi Hakk\u0131nda S\u0131k\u00e7a Sorulan Sorular<\/h2>\n<h3>FAI, her yeni enjeksiyon kal\u0131b\u0131 i\u00e7in mi gereklidir, yoksa sadece d\u00fczenlenmi\u015f end\u00fcstriler i\u00e7in mi?<\/h3>\n<p>FAI is mandatory for aerospace (AS9102), automotive (PPAP), and medical device (ISO 13485 \/ FDA 21 CFR Part 820) supply chains. However, any manufacturer running injection molds for precision assemblies should perform FAI regardless of industry, because the cost of discovering dimensional non-conformance at production scale vastly exceeds the cost of a structured first-article inspection. At ZetarMold, we recommend FAI for any production program with tolerances tighter than \u00b10.15 mm or any assembly with critical-to-function fit interfaces, irrespective of the customer&#8217;s industry sector.<\/p>\n<h3>FAI s\u0131ras\u0131nda tipik olarak ka\u00e7 par\u00e7a incelenir?<\/h3>\n<p>The standard minimum is 3\u20135 parts from the actual production mold, running under production-intent process parameters. For multi-cavity molds, parts should be taken from every cavity\u2014not just one representative part. If you have a 4-cavity mold, a proper FAI measures parts from all four cavities and records cavity-specific data. Cavity-to-cavity variation is a common failure mode in injection molding; FAI is the only way to confirm that all cavities are within tolerance simultaneously. Some customers specify larger sample sizes (10\u201330 parts) for statistical process capability calculations.<\/p>\n<h3>FAI ve PPAP aras\u0131ndaki fark nedir?<\/h3>\n<p>FAI (First Article Inspection) is a measurement and verification activity\u2014it confirms that a specific part from a specific mold meets its drawing. PPAP (Production Part Approval Process) is a broader submission package required by automotive customers that includes FAI data as one of its 18 required elements, alongside design records, process flow diagrams, control plans, MSA studies, and capacity analysis. PPAP Level 3 (the most common) requires all 18 elements to be submitted to and approved by the customer. FAI is necessary but not sufficient for PPAP; PPAP wraps FAI inside a larger quality management framework.<\/p>\n<h3>FAI, kal\u0131p\u00e7\u0131 taraf\u0131ndan m\u0131 yap\u0131labilir yoksa ba\u011f\u0131ms\u0131z bir laboratuvar taraf\u0131ndan m\u0131 yap\u0131lmal\u0131d\u0131r?<\/h3>\n<p>In most commercial and industrial applications, the molder&#8217;s own quality team performs the FAI using calibrated, NIST-traceable measurement equipment. The customer reviews and approves the FAIR. For aerospace and defense applications, some customers require that FAI be witnessed by their own quality representative or a third-party inspection agency. Medical device applications under FDA oversight may require measurement system analysis (MSA \/ Gage R&#038;R studies) to demonstrate that the molder&#8217;s measurement process itself is capable before FAI data is considered valid.<\/p>\n<h3>What should I do if I receive a FAIR with some features marked &#8216;actual dimension not reported&#8217;?<\/h3>\n<p>Any feature listed on the drawing that appears in the ballooned inspection plan must be measured and reported. &#8216;Not reported&#8217; entries indicate an incomplete FAI and are not acceptable for formal approval. Common reasons for missing measurements include: features that are difficult to access with standard tooling (requiring fixtures or specialized probes), features inadvertently omitted during drawing ballooning, or features that require destructive testing (cross-section cuts for internal wall thickness). For each case, the molder must either provide measurement data, request a customer deviation, or use alternative measurement methods. Accept no FAIR with blank or &#8216;N\/A&#8217; entries unless formally approved.<\/p>\n<h3>Malzeme b\u00fcz\u00fclmesi enjeksiyon kal\u0131plamada FAI sonu\u00e7lar\u0131n\u0131 nas\u0131l etkiler?<\/h3>\n<p>Material shrinkage is the primary reason why injection-molded part dimensions differ from the mold cavity dimensions, and it is a major source of FAI failures. Most engineering thermoplastics shrink 0.3\u20132.0% as they cool from melt temperature to ambient. The mold cavity is intentionally cut oversize by the expected shrinkage factor, but actual shrinkage varies with wall thickness, melt temperature, packing pressure, cooling rate, and material lot. FAI catches cases where actual shrinkage deviates from the design assumption. When FAI shows a systematic dimensional offset across all measured features, the root cause is almost always a shrinkage factor error, which is corrected by steel adjustment.<\/p>\n<hr style=\"margin:2em 0;border:none;border-top:1px solid #e0e0e0;\" \/>\n<ol class=\"footnotes\">\n<li id=\"fn:1\">\n<p><strong>First Article Inspection:<\/strong> First Article Inspection (FAI) is a formal validation process that verifies the first production part or assembly from a new or modified manufacturing process meets all engineering design requirements before mass production begins. <a href=\"#fnref1:1\" class=\"footnote-backref\">\u21a9<\/a><\/p>\n<\/li>\n<li id=\"fn:2\">\n<p><strong>AS9102:<\/strong> AS9102 refers to the aerospace industry standard that defines requirements for First Article Inspection reports, specifying documentation, dimensional verification, and material certification procedures. <a href=\"#fnref1:2\" class=\"footnote-backref\">\u21a9<\/a><\/p>\n<\/li>\n<li id=\"fn:3\">\n<p><strong>Coordinate Measuring Machine:<\/strong> A Coordinate Measuring Machine (CMM) is a precision metrology device that measures the physical geometrical characteristics of a part by probing its surface with a contact or non-contact sensor, typically achieving accuracy within \u00b10.001 mm. <a href=\"#fnref1:3\" class=\"footnote-backref\">\u21a9<\/a><\/p>\n<\/li>\n<li id=\"fn:4\">\n<p><strong>PPAP:<\/strong> PPAP (Production Part Approval Process) is an automotive industry standard that requires suppliers to demonstrate, through documented evidence including FAI data, that their manufacturing process can consistently produce parts meeting all customer specifications. <a href=\"#fnref1:4\" class=\"footnote-backref\">\u21a9<\/a><\/p>\n<\/li>\n<li id=\"fn:5\">\n<p><strong>GD&#038;T:<\/strong> GD&#038;T (Geometric Dimensioning and Tolerancing) is an engineering notation system used on technical drawings to define the allowable variation in form, size, orientation, and location of part features, providing a universal language for precision manufacturing. <a href=\"#fnref1:5\" class=\"footnote-backref\">\u21a9<\/a><\/p>\n<\/li>\n<\/ol>\n<p><script type=\"application\/ld+json\">{\n    \"@context\": \"https:\\\/\\\/schema.org\",\n    \"@type\": \"FAQPage\",\n    \"mainEntity\": [\n        {\n            \"@type\": \"Question\",\n            \"name\": \"Is FAI required for every new injection mold, or only for regulated industries?\",\n            \"acceptedAnswer\": {\n                \"@type\": \"Answer\",\n                \"text\": \"FAI is mandatory for aerospace (AS9102), automotive (PPAP), and medical device (ISO 13485 \\\/ FDA 21 CFR Part 820) supply chains.
