The bottom cup — also called the burner base or aluminum cup — is the component that often gets overlooked in SABAF burner OEM planning, yet it anchors the whole burner system. Choosing it correctly affects fit, heat distribution, and cost. Here is how to think through bottom cup options for your OEM program.
The bottom cup sits beneath the flame spreader and burner cap, directing the gas-air mixture upward into the ports and providing a stable, heat-resistant base. Its depth, diameter, and material all influence how cleanly and efficiently the burner burns. A poorly matched cup causes flame lift, uneven heating, and premature wear.
SABAF-compatible burner systems are sold in two main combinations. The first is cap plus flame spreader only (no bottom cup), which is lighter and cheaper — ideal when the stove's existing cup is retained. The second is cap plus spreader plus bottom cup, a complete drop-in assembly that simplifies replacement and standardization. Your OEM spec should state clearly which combination you need.
Bottom cups are typically high-temperature aluminum alloy, chosen for its heat resistance, light weight, and stable casting. Within aluminum, alloy grade and wall thickness can be tuned for thermal performance and cost. THREEMI works with you to select the right material and thickness for your burner's heat output and your target price point.
The smart OEM approach is to standardize the cup across your burner line — one base platform, with differentiated caps and finishes on top. That reduces tooling cost and inventory while still giving your brand a distinct, complete burner system.
