Quality cookware starts with the base. We help global manufacturers and brands source high-performance multi-ply stainless steel discs. From raw material verification to bond-strength testing, we ensure your supply chain delivers the foundation for premium induction-ready cookware.
Why Precision Matters in Multi-Ply Disc Procurement
For cookware brands, a failure in the disc bond means a product recall. In the China supply chain, the real challenges aren’t in the price, but in the technical specs:
- The Material Grade Trap: Is the inner layer truly SUS304 (18/10) or a cheaper 200 series? Is the bottom layer SUS430 with proper magnetic properties for induction?
- Bonding Integrity: Poor brazing or impact bonding leads to “delamination” (layers splitting) when the end-user heats the pan.
- Thickness Consistency: Variations in the aluminum core thickness lead to uneven heat distribution and warped pans.
HSY Sourcing monitors the production process to ensure the multi-ply structure is inseparable and meets international food-grade standards.
Customizable Multi-Ply Solutions
We source a wide range of composite discs tailored to your production line:
- 3-PLY Discs (SS/AL/SS): The industry standard for high-end induction cookware (304 Stainless Steel + Aluminum Core + 430 Stainless Steel).
- 2-PLY Discs (SS/AL or SS/Copper): For specialized cookware designs and cladding.
- Custom Diameters & Thickness: Ranging from small milk pan sizes to large stockpot discs, with precision-cut edges.
- Surface Finish: Available in mill finish or pre-polished states based on your manufacturing needs.
Our Material & Quality Protocol
We don’t just count the pallets. We verify the metallurgy:
- Spectrum Analysis (PMI Test): We use handheld spectrometers to verify the chemical composition of the stainless steel layers (Ni and Cr content).
- Bonding Strength Test: We supervise destructive testing to ensure the layers are molecularly bonded and won’t separate under thermal stress.
- Flatness & Tolerance Check: Using precision calipers and gauges to ensure every disc meets the ±0.05mm tolerance required for automated deep-drawing.
- Hardness Testing: Ensuring the metal is in the correct annealed state for your stamping or spinning machines.
Partner with HSY Sourcing: Strengthen Your Cookware Foundation
The cookware industry is moving toward more efficient heat conduction and sustainable manufacturing. HSY Sourcing helps you capture these opportunities with confidence.
With deep sourcing expertise in China’s metalwork hubs (like Jiangmen and Chaozhou), HSY Sourcing connects you with reliable 2-PLY/3-PLY disc manufacturers. We manage raw material traceability, bond-strength consistency, and logistics from end to end. We simplify your procurement, giving you clearer control over material cost and finished product performance.
FAQ
Q: Can you provide material mill certificates (MTC)? A: Yes. We ensure every batch comes with an official MTC, and we cross-verify it with our own independent lab testing to ensure honesty in material grades.
Q: Do you source discs for both impact bonding and brazing processes? A: Yes. We match you with suppliers whose disc surface treatment and alloy composition are optimized for your specific joining technology.
Q: What is the lead time for custom-sized discs? A: Generally, it takes 20-30 days for production, depending on the raw material availability and the quantity of the order.
