Why Blanks Beat Pre-Finished Bases
Pressing your own bases from certified blanks keeps drawing depth, trim line and base profile under your control. You buy one roll-bonded material instead of three separate sheets, skip in-house bonding entirely, and eliminate the delamination risk that welded or brazed bases carry after thousands of thermal cycles on the hob.
Send Us Your Size List
The fastest quotation route is a simple table: diameter (mm) × thickness (mm) × monthly pieces or tons, for example Φ280 × 2.5 × 8,000 pcs/month. Mixed diameters in one container are welcome; our team maps each size to the nearest ex-stock die so your tooling cost stays at zero.
How Peel Strength Stays Stable Batch After Batch
Interface cleanliness is controlled on our surface-treatment line before bonding; the 1450 mm mill applies high rolling force at 10–15 m/min; hydrogen bright annealing relieves stress without oxidising the interface. Every finished coil is peel-tested to GB/T 2792-2014 or GB/T 6396-2008, and the measured N/mm value is printed on the MTC that travels with your cargo, for triply stainless steel circle blanks, paper evidence beats marketing adjectives.
Documents & Compliance
Each shipment carries per-coil MTC, commercial invoice, packing list and B/L; CO/CQ (including Form E for ASEAN buyers) on request. Our quality system is certified to ISO 9001:2015 and ISO 14001:2015 by CQM with IQNET international recognition, see ISO 9001 quality management principles for the scope such certification covers.
