Supplier A: KRW 280,000 per set. Supplier B: KRW 420,000. Supplier C (Korea Ever-Power): KRW 380,000. He ordered from Supplier A &#8212; a 35% saving on the catalog price.<\/p>\n<p style=\"margin-bottom: 16px; font-size: 15px; color: #2c3e50; line-height: 1.82;\">The Supplier A delivery arrived with a &#8220;certificate of conformance&#8221; &#8212; a single-page document stating the parts met the specification. No material certificate. No CMM report. No heat treatment record. At incoming inspection, the bore measured 35.08 mm &#8212; outside the H7 upper limit of 35.025 mm. The bore was re-machined in-house at a cost of KRW 80,000 per set, bringing the effective unit price to KRW 360,000. Three months later, oil analysis showed elevated copper at 2,400 ppm. One year later, the average service life of the Supplier A gear sets was 11 months versus the manufacturer&#8217;s intended 48-60 months. The material certificate that was never provided would have confirmed: wheel alloy copper content 62% (minimum standard: 78%), no tin content listed at all. The wheel was brass, not tin bronze.<\/p>\n<p style=\"margin-bottom: 16px; font-size: 15px; color: #2c3e50; line-height: 1.82;\">The difference in true cost: Supplier A at KRW 280,000 + repairs + 3.5 additional replacements over 4 years = effective 4-year cost KRW 1,260,000+ per drive. Korea Ever-Power at KRW 380,000 with confirmed material and geometry = one replacement in 4 years = KRW 380,000 per drive.<\/p>\n<div style=\"border-left: 4px solid #1a9090; background: #eef8f6; padding: 18px 22px; margin: 28px 0; border-radius: 0 6px 6px 0;\">\n<p style=\"margin: 0; font-size: 14px; color: #0a2828; line-height: 1.72;\"><strong style=\"color: #0a3838;\">What this guide covers:<\/strong> What a complete and credible worm gear quotation contains; what documentation is required and what &#8220;certificate of conformance&#8221; does and does not prove; how to calculate the true 4-year cost of a worm gear supply relationship; a supplier qualification checklist; and the specific red flags that indicate a low-quality supplier before the first order is placed.<\/p>\n<\/div>\n<div style=\"display: flex; flex-wrap: wrap; gap: 16px; margin: 24px 0 28px;\">\n<div style=\"flex: 0 1 280px; max-width: 100%; border-radius: 8px; overflow: hidden; box-shadow: 0 4px 18px rgba(4,28,30,.14);\"><img decoding=\"async\" style=\"width: 100%; height: auto; display: block;\" src=\"https:\/\/wormwheelgear.top\/wp-content\/uploads\/2026\/04\/worm-gear-workshop-1.webp\" alt=\"\" title=\"\"><\/div>\n<div style=\"flex: 0 1 280px; max-width: 100%; border-radius: 8px; overflow: hidden; box-shadow: 0 4px 18px rgba(4,28,30,.14);\"><img decoding=\"async\" style=\"width: 100%; height: auto; display: block;\" src=\"https:\/\/wormwheelgear.top\/wp-content\/uploads\/2026\/04\/Worm-Gear-set.webp\" alt=\"\" title=\"\"><\/div>\n<\/div>\n<hr style=\"border: none; border-top: 2px solid #c8dcd8; margin: 48px 0;\" \/>\n<h2 style=\"font-size: clamp(20px,2.8vw,30px); font-weight: 800; color: #041c1e; margin: 48px 0 14px;\">What a Complete Worm Gear Quotation Contains<\/h2>\n<p style=\"margin-bottom: 16px; font-size: 15px; color: #2c3e50; line-height: 1.82;\">A quotation is not just a price.

A price more than 20-25% below market average for a stated specification means one or more of the following: the specification is not what was stated (material substitution, skipped inspection); the vendor is a trader, not a manufacturer; or there is a significant quality compromise that will appear within 6-12 months of operation.<\/p>\n<\/div>\n<div style=\"flex: 1 1 260px; min-width: 240px; border-radius: 10px; padding: 18px; background: #fde8e8; border-left: 4px solid #c02010;\">\n<h4 style=\"font-size: 14px; font-weight: bold; color: #041c1e; margin: 0 0 8px;\">No material certificate offered<\/h4>\n<p style=\"font-size: 13px; color: #2a3830; line-height: 1.68; margin: 0;\">A supplier who does not offer a material certificate to mill heat number as standard documentation has a quality management system that cannot trace component materials to their origin. This is disqualifying for food-grade, medical, marine, construction safety, and automotive OEM supply. For general industrial supply, it means you cannot verify the material when a failure occurs.<\/p>\n<\/div>\n<div style=\"flex: 1 1 260px; min-width: 240px; border-radius: 10px; padding: 18px; background: #fff8ec; border-left: 4px solid #c9892a;\">\n<h4 style=\"font-size: 14px; font-weight: bold; color: #041c1e; margin: 0 0 8px;\">&#8216;Certificate of conformance&#8217; as sole documentation<\/h4>\n<p style=\"font-size: 13px; color: #2a3830; line-height: 1.68; margin: 0;\">A CoC is the supplier self-certifying conformance. It proves only that the supplier states the part meets the specification. Without CMM data and material certificate, the statement is unverifiable. CoC-only documentation is appropriate for commodity fasteners; it is inadequate for engineered mechanical components with specific material and dimensional requirements.<\/p>\n<\/div>\n<div style=\"flex: 1 1 260px; min-width: 240px; border-radius: 10px; padding: 18px; background: #fff8ec; border-left: 4px solid #c9892a;\">\n<h4 style=\"font-size: 14px; font-weight: bold; color: #041c1e; margin: 0 0 8px;\">No sample option for first order<\/h4>\n<p style=\"font-size: 13px; color: #2a3830; line-height: 1.68; margin: 0;\">A supplier who requires a minimum order of 50 or 100 pieces with no sample option cannot be qualified without committing production quantities. Quality issues discovered at 100 pieces in production are far more expensive to resolve than quality issues found at 3 sample pieces. Any credible worm gear manufacturer can supply 3-5 sample pieces at sample pricing for initial qualification.<\/p>\n<\/div>\n<div style=\"flex: 1 1 260px; min-width: 240px; border-radius: 10px; padding: 18px; background: #f5f8fc; border-left: 4px solid #2060a0;\">\n<h4 style=\"font-size: 14px; font-weight: bold; color: #041c1e; margin: 0 0 8px;\">Response time of more than 1 working day for standard enquiry<\/h4>\n<p style=\"font-size: 13px; color: #2a3830; line-height: 1.68; margin: 0;\">For a standard specification worm gear enquiry (module, ratio, bore, quantity), a response time of more than 1 working day indicates either that the supplier does not stock raw material (and must source before quoting), that the sales function is understaffed, or that the enquiry is not being prioritised. All of these create risk in actual supply chain management.<\/p>\n<\/div>\n<div style=\"flex: 1 1 260px; min-width: 240px; border-radius: 10px; padding: 18px; background: #f5f8fc; border-left: 4px solid #2060a0;\">\n<h4 style=\"font-size: 14px; font-weight: bold; color: #041c1e; margin: 0 0 8px;\">Manufacturing location is unclear<\/h4>\n<p style=\"font-size: 13px; color: #2a3830; line-height: 1.68; margin: 0;\">A trader quoting as a manufacturer will often be vague about where the gears are made. If the quotation response does not state the manufacturing location, ask explicitly. If the response is unclear, treat as a risk: quality control by a trader over a subcontractor is inherently less reliable than quality control by the manufacturer.<\/p>\n<\/div>\n<\/div>\n<hr style=\"border: none;
