Explore our precision-engineered aluminium cans, easy-open ends, and high-purity coil stock certified for global high-speed filling lines.
In the modern fast-moving consumer goods (FMCG) beverage packaging sector, the transition toward lightweighting, structural integrity, and ultra-high-speed line efficiency has placed the SOT 200 CDL (Stay-On Tab 200 Diameter Contour Ends / Clean Diameter Lids) at the core of global procurement strategies. As a premier wholesale SOT 200 CDL manufacturer, service partner, and global supplier, Shanghai Friend Metals Technology Co., Ltd. (operating globally since 2010) delivers advanced metal packaging solutions tailored to multinational beverage bottlers, craft breweries, nutritional product formulators, and industrial canners across more than 40 countries.
The global beverage ecosystem is experiencing a profound paradigm shift driven by stringent carbon neutrality directives, rising raw material costs, and aggressive sustainability mandates. Traditional 202 SOT ends are rapidly giving way to 200 CDL end configurations. The 200 CDL design shrinks the neck finish diameter to 50mm while utilizing a modified contour profile that maintains superior double-seam strength, internal pressure resistance (exceeding 6.2 bar), and exceptional buckle resistance—all while reducing aluminium shell weight by 8% to 12% per unit.
Multinational beverage brands require extreme uniformity across millions of units. Our SOT 200 CDL ends feature exact curl thickness, precise countersink depths, and uniform compound lining to eliminate high-speed seamer jams.
By switching from standard ends to 200 CDL lightweight ends, enterprise fillers achieve immediate reductions in freight weight and raw metal tonnage, directly lowering corporate Scope 3 greenhouse gas emissions.
Every lot manufactured at Shanghai Friend Metals undergoes comprehensive Enamel Rater optical leak testing, double-seam teardown dimensional verifications, and pop & pull force evaluation under ISO 9001 quality protocols.
Comprehensive metallurgical breakdown, dimensional parameters, and comparative engineering benchmarks for packaging procurement managers.
The SOT 200 CDL (Clean Diameter Lid / Contour Diameter end) relies on high-grade 5182-H48 aluminium alloy shell stock paired with 5052-H19 aluminium tab stock to optimize tensile strength and work-hardening properties. During stamping, the contour profile is engineered to absorb axial forces and internal pressures without experiencing premature buckle failure.

Seamless integration onto customer filling lines is a core deliverable of Shanghai Friend Metals OEM service. SOT 200 CDL ends are manufactured with precise curl dimensions (curl width, radius, and chuck profile tolerances held within ±0.05mm). This tight tolerance profile guarantees flawless compatibility with automated seamers including Ferrum, Angelus, Continental Can, Comaco, and KHS high-speed filling lines running at speeds up to 1,800 cans per minute (CPM).
Strategic B2B procurement methodologies engineered for high-volume enterprise buyers across global beverage markets.
Optimized for carbonated soft drinks (CSD), beer, hard seltzers, and sparkling water requiring pressure retention up to 6.8 bar and pasteurization resistance up to 68°C for 20 minutes without deformation.
Tailored solutions for infant milk powder, protein formulas, and coffee powders utilizing specialized 300#, 307#, 401#, and 502# powder lids with hermetic foil pull-ring barriers and nitrogen-flush retention capability.
Complete single-source procurement supplying 3104-H19 aluminium can body stock (200ml, 250ml, 330ml, 355ml, 473ml, 500ml) paired with customized 8011 and 5182 lacquered coil slit to exact OEM width tolerances.
At Shanghai Friend Metals, every manufacturing run is protected by an aggressive 7-step quality control architecture. Incoming raw material coils from top-tier primary aluminium smelters are validated via spectrometer melt analysis. During precision high-speed stamping on cupping and shell presses, real-time laser vision sensors inspect 100% of ends for micro-cracks, pinholes, tab misalignments, and compound seal voids.
Prior to container loading, sample batches are subjected to destructive double-seam teardown analysis (evaluating cover hook, body hook, overlap percentage, and seam gap thickness). Statistical process control (SPC) data sheets and mill certificates accompany every sea freight shipment, establishing an unbroken chain of traceability.

The 200 CDL (Contour Diameter End) features a 50mm seam diameter compared to the 52.5mm diameter of a standard 202 end. The CDL profile incorporates an optimized countersink angle and a unique radius profile that allows thinner aluminium shell gauge (typically 0.205mm–0.215mm) to withstand equal or higher internal pressures (≥ 6.2 bar) while saving approximately 10% in metal weight per end.
For standard unprinted or stock lacquered SOT 200 CDL ends, our MOQ starts at 200,000 pieces (one full shipping pallet lot), which can ship within 15 working days. For custom color tabs, laser-engraved promotional codes, or custom end decoration, the typical production batch MOQ is 1,000,000 pieces per design.
Yes. Our 200 CDL ends are coated with premium BPA-NI (BPA Non-Intent) internal lacquers specifically formulated to resist low-pH acidic soft drinks, energy beverages, and high-alcohol craft beers. Every lot undergoes Enamel Rater testing (<2.0 mA electrical conductivity resistance) to guarantee zero lacquer breakdown or corrosion over long shelf life.
Our technical support team provides precise seaming chuck and roll profile drawings prior to delivery. We ship pre-production sample lots for double-seam teardown evaluation on your seamer (Ferrum, Angelus, KHS, etc.). Our engineers analyze seam thickness, cover hook length, body hook length, and overlap percentage to ensure leak-free operation before mass delivery.
Ends are packed into heavy-duty paper sleeves or polyethylene sleeves under cleanroom conditions, then loaded into corrugated master cartons or wooden crates equipped with silica gel desiccant packs. Cartons are stacked on ISPM-15 heat-treated fumigated pallets, secured with corner boards, and enclosed in heavy stretch-hood shrink film.
