Die Casting Mould for Cookware and Pots Custom

• Custom die casting mould exclusively for aluminum alloy cookware: non-stick pans, soup pots, stockpots, and induction-compatible cookware, tailored to B2B cookware manufacturers’ size/shape needs.

• Applicable to food-grade aluminum alloys (ADC12, A380) — ensures cookware meets FDA (U.S.) and LFGB (EU) food contact standards, with no heavy metal leaching.

• Features 1-6 cavity configurations: 1-cavity for large stockpots (24-32cm diameter), 6-cavity for small pans (16-20cm diameter), matching low/high-volume production.

• Achieves ±0.03mm dimensional accuracy (critical for cookware thickness uniformity: 2-5mm) and Ra 0.2μm cavity surface roughness (reduces post-polishing time by 60%).

• Integrates cookware-specific designs: heat-conducting base optimization (3mm thick for even heating), non-stick coating pre-treatment grooves, and anti-deformation reinforcing ribs.

• Complies with industrial standards (ISO 9001, CE) and supports global B2B export, compatible with 200T-800T cold-chamber die casting machines (LH, Yizumi, Haitian).

Visually, the mold has a robust, gray H13 steel frame—streamlined (600mm width for 4-cavity pan mold) to fit cookware production lines without blocking access. When you touch the cavity surface, it feels mirror-smooth (Ra 0.2μm) and cool to the touch (even after 100 cycles) thanks to the internal cooling channels, unlike traditional molds that leave cookware with rough, scratch-prone surfaces. The mold’s guide pins are polished to a chrome finish, sliding into bushings with a soft “click” — no grinding that damages cookware edges. There’s a faint, clean metallic scent (no chemical residues from low-quality lubricants), a sign of food-grade-compatible processing. During production, you’ll notice molten aluminum flows evenly into the cavity’s heat-conducting base (3mm thickness, ±0.02mm tolerance)—no air bubbles that cause hot spots. The demolding system uses gentle air pressure (0.3MPa) to release cookware without scratches; post-production, the pan’s surface is smooth enough for direct non-stick coating (no extra polishing). Every detail—from the food-grade mold release agent compatibility (avoids residue) to the etched size marks (16cm/18cm) — is designed to make aluminum cookware production reliable, compliant, and cost-effective for B2B manufacturers.

• Ultra-Precision Ensures Even Cookware Heating (Cuts Rejects by 80%): The mold’s 5-axis CNC machining (tolerance ±0.005mm) and EDM wire cutting create cavities with ±0.03mm dimensional accuracy—ensuring cookware thickness uniformity (2-5mm, ±0.02mm). A European cookware brand reduced induction heating failure rates from 18% to 3.6%, saving $12,240/year in rework. The heat-conducting base design (3mm thick, no thin spots) eliminates hot spots—tests show temperature variation across pan surfaces drops from 25℃ to 5℃, meeting European EN 12983 cookware standards. For stockpots, the mold’s uniform wall thickness (4mm) ensures even boiling, reducing customer complaints by 70%.

• Food-Grade Compliance Meets Global Standards: The mold’s cavity is polished to Ra 0.2μm and treated with a food-grade-compatible coating (no heavy metals) — ensuring cookware meets FDA 21 CFR 175.300 (U.S.) and LFGB §30 (EU) food contact requirements. A U.S. cookware manufacturer passed Walmart’s supplier audit with zero non-compliances, winning a \(2M annual order. The mold’s compatibility with food-grade aluminum alloys (ADC12, A380) and non-stick coating pre-treatment grooves (0.1mm depth) eliminates coating adhesion issues— a Chinese brand reduced non-stick peeling rates from 10% to 1.5%, avoiding \)8,500/month in returns.

• Multi-Cavity Design Boosts Production Efficiency (Saves 40% Time): The 1-6 cavity configuration adapts to production volumes: 6-cavity for small pans (16-20cm) increases output by 500% vs. 1-cavity; 1-cavity for large stockpots (32cm) avoids overloading. A Brazilian cookware factory with 3 4-cavity molds increased daily pan production from 800 to 3,200, meeting a $1.5M order from a supermarket chain. The mold’s fast cycle time (40-60 seconds/cavity) — 20% faster than generic molds — adds 120 extra pans/day per machine. The self-lubricating guide pins (PTFE-lined) also cut maintenance time by 3 hours/week (no monthly oiling), reducing downtime by 15%.

• Polished Cavities Reduce Post-Processing (Cuts Labor by 60%): The cavity’s Ra 0.2μm surface roughness (achieved via 3-stage polishing) eliminates 60% of manual polishing work— a U.S. factory reduced polishing labor from 4 hours to 1.6 hours per batch, saving \(5,400/month. For non-stick cookware, the smooth surface ensures uniform coating application (thickness variation ±5%)— reducing coating material use by 20% (from 50ml to 40ml per pan). The mold’s demolding air pressure system (0.3MPa) also prevents scratches— cookware surface defect rates drop from 8% to 1%, cutting rework costs by \)6,000/year.

• Durable Design Extends Mold Lifespan (300,000+ Cycles): The mold’s H13 die steel (52-54 HRC hardness) resists wear from aluminum oxide— ensuring consistent precision for 300,000+ cycles (vs. 150,000 cycles for low-grade steel). A Thai cookware factory used 2 molds for 3 years with zero cavity replacement, saving $30,000 in mold costs. The internal cooling channels (5mm from cavity surface) reduce thermal stress— mold warpage rates drop by 80%, maintaining dimensional accuracy over time. For high-volume production (10,000+ pieces/month), the mold’s corrosion-resistant vent holes (prevents aluminum buildup) ensure 24/7 operation without clogging.

• Non-Stick Pans (16-24cm, ADC12 Aluminum): Ideal for 4-6 cavity molds—producing pans with Ra 0.2μm surfaces (direct non-stick coating). A Chinese cookware brand used 3 6-cavity molds to produce 1.2 million pans/year—polishing labor cut by 60%, and non-stick adhesion rates improved to 98.5%, winning a contract with Lidl.

• Induction Soup Pots (20-28cm, A380 Aluminum): Perfect for 2-cavity molds— the heat-conducting base (3mm thickness, ±0.02mm) ensures induction compatibility. A European brand reduced induction failure rates from 15% to 2%, meeting EN 12983 standards and increasing sales by 35%.

• Large Stockpots (24-32cm, ADC12 Aluminum): Suitable for 1-cavity molds— uniform wall thickness (4mm) prevents warping during boiling. A U.S. restaurant supply company produced 50,000 stockpots/year— customer complaints about uneven heating dropped from 20% to 3%, saving $12,000/year in returns.

• Custom Specialty Cookware (e.g., Woks, Grill Pans): The mold’s customization flexibility supports unique shapes— a Korean brand ordered custom wok molds (36cm diameter, curved sides) — delivered in 18 days, enabling a new product launch that captured 15% of the local wok market.
