Production line and factory setup overview
A small/medium food-contact metalware line converting certified aluminium circles into one deep-drawn pot or pan family through incoming alloy and surface inspection, circle lubrication, guarded hydraulic deep drawing, optional intermediate annealing for the approved alloy/draw ratio, trimming and beading, base finishing, controlled washing, internal and external polishing or approved coating, handle-hole punching, riveting, leak/rocking checks, food-contact verification and packing.
Recommended lowest-entry line configuration Launch one uncoated 20-28 cm aluminium cooking-pot family from purchased food-grade aluminium circles. Screen a 200-315 t four-column hydraulic press with matched draw dies, trim/bead machine, washer, inner/outer polishing stations, punching/riveting jigs and leak/flatness gauges. Add annealing only after draw trials. Do not feed unsorted scrap directly; remelting, alloy control and circle casting/rolling are a separate metallurgical plant.
Production process and implementation sequence
- Circle certificate, gauge and surface release
- Lubrication and first deep draw
- Optional redraw or approved annealing
- Trim, bead and base finishing
- Wash and controlled polishing
- Handle punching, riveting and lid fit
- Leak, flatness and handle proof checks
- Food-contact release and packing
Products, capacity and market fit
- Cooking pots are a repeat household and hospitality product.
- Purchased certified circles let a smaller factory avoid unsafe uncontrolled remelting.
- One body family shares forming, trimming, polishing and handle fixtures.
- Alloy chemistry, surface finish, handle retention and food-contact tests protect users.
- Uncoated aluminium cooking pot - Diameter, volume, alloy, body/base thickness, rim, lid, handles, finish and food-contact limit - Households, restaurants and institutional kitchens
- Aluminium saucepan or shallow pan - Separate dedicated draw die, rim, base flatness, handle system and approved surface finish - Retail and hospitality after tooling validation
