Production line and factory setup overview
A micro/small sheet-metal appliance workshop producing one tested solid-fuel cookstove or room-heater family through combustion and safety design, sheet blanking, punching, bending and rolling, combustion-chamber and flue fabrication, fixture welding, refractory or ceramic-liner preparation, grate/door/damper assembly, heat-resistant coating, controlled curing, leak and stability checks, emissions/efficiency testing and traceable packing.
Recommended lowest-entry line configuration Choose one fuel and one use: a vented wood/biomass room heater or a cooking stove, never both under one untested design. Begin with CNC plasma or shear, press brake, slip roll, punches, welding fixtures, refractory-liner molds, heat-resistant paint booth/oven, flue-leak rig and an instrumented combustion-test hood. Freeze the design only after local-fuel efficiency, CO, surface-temperature, stability and durability tests.
Production process and implementation sequence
- Use/fuel definition and safety design
- Sheet nesting, blanking and punching
- Bending, rolling and flue formation
- Fixture welding of body and combustion chamber
- Refractory liner, grate and door preparation
- Damper, handles and guards assembly
- Heat-resistant coating and curing
- Leak, stability, efficiency, CO and durability release
Products, capacity and market fit
- Cold Afghan winters and expensive fuel create demand for safer efficient heaters.
- Local sheet metal and clay/refractory inputs can support assembly and repair.
- One tested model avoids uncontrolled variations that raise carbon-monoxide risk.
- Efficiency and safety claims require combustion tests, not visual inspection.
- Vented solid-fuel room heater - Rated fuel/output, flue, clearance, efficiency, CO, surface temperature and user instructions - Homes, shops and institutions
- Efficient biomass cookstove - Approved fuel, pot interface, thermal efficiency, emissions, stability and safe-use instructions - Households and small food businesses after separate validation
