We have abundant customized landing cases covering multiple application scenarios:

First, for industrial burner systems, customized air-gas mixing housings are supplied. Optimized internal runner design realizes uniform mixing of combustion air and fuel gas, stabilizes combustion efficiency and reduces emission pollutants. The high-rigidity structure adapts to long-term continuous operation under high-temperature working conditions.

Second, for heating boiler combustion assemblies, we produce sealed gas distribution housings. Strict air tightness control effectively prevents gas leakage; anti-thermal deformation design ensures stable flow distribution under alternating hot and cold working environments, improving boiler operational safety.

Third, for thermal treatment furnace combustion equipment, lightweight precision air intake housings are customized. Precision machining ensures stable air supply flow, supporting accurate flame control of heat treatment furnaces and guaranteeing consistent furnace temperature.

Fourth, for commercial kitchen combustion systems, compact integrated air & gas housings are developed. Miniaturized structure saves internal equipment space, with good corrosion resistance against humid environments and oil fume erosion, lowering equipment failure frequency.

We provide multiple grades of cast aluminum alloy and machined aluminum alloy materials for air & gas housing parts of combustion equipment. Selected materials feature excellent air tightness, thermal stability, pressure resistance and oxidation resistance, suitable for high-temperature, pressure-bearing and continuous operating environments of combustion systems.

• ADC12 Die-cast Aluminum Alloy: Excellent fluidity for forming complex internal flow channels, low shrinkage porosity and stable dimensional accuracy after casting. Cost-effective, widely used for conventional air-gas mixing housings of medium and low-temperature burners.

• A380 Aluminum Alloy: Balanced mechanical strength and thermal stability, strong resistance to thermal expansion and contraction deformation. Ideal for mid-end industrial burner gas distribution housings with medium temperature and pressure requirements.

• ZL104 Cast Aluminum Alloy: Ultra-low internal porosity, outstanding air tightness performance after precision processing. Preferred material for high-standard sealed housings used on boilers and high-temperature industrial combustion equipment with strict anti-leakage requirements.

• 6061 Machined Aluminum Alloy: High dimensional precision after CNC processing, good welding performance and corrosion resistance. Suitable for small-batch, special-structure split air intake housings and prototype customized products.

To guarantee every batch of combustion equipment air & gas housing parts meets industry safety norms and customized technical specifications, we build a full-process, multi-dimensional high-standard inspection system covering raw material incoming check, in-process monitoring, semi-finished testing and finished goods delivery, to fully eliminate hidden risks such as gas leakage.

The complete inspection and testing process includes six core links:

• Raw material incoming inspection: Conduct alloy composition spectroscopy analysis, hardness testing and impurity inspection for incoming aluminum ingots and aluminum blanks. Unqualified raw materials with excessive impurities are rejected to control quality from the source.

• In-process production inspection: Quality inspectors implement periodic sampling inspection during die casting and CNC processing, focusing on dimensional tolerance, flatness of sealing surfaces and flow channel smoothness, adjusting processing parameters timely to avoid batch defects.

• Semi-finished product performance pre-test: Conduct air tightness test and pressure resistance test on semi-finished housings to screen out workpieces with internal pores and potential leakage risks.

• Full-item inspection of finished products: Inspect appearance, dimensional accuracy, thread matching and sealing surface integrity one by one after deburring and finishing.

• Sampling aging test: Randomly select products for alternating cold and hot cycle testing, long-term pressure maintaining air tightness testing, simulating the long-running working environment of combustion equipment to verify durability.

• Final delivery verification: Recheck all qualified finished products, sort out complete material certificates and factory inspection reports. Packaging and shipment are arranged only after all safety indicators pass verification.

The rigorous testing system effectively avoids common defects including air leakage, dimensional out-of-tolerance, thermal deformation and internal runner burr blockage. All housings maintain stable sealing and fluid conveying performance under temperature and pressure fluctuations, meeting strict safety standards of combustion equipment.

Our combustion equipment air & gas housing parts adopt complete standardized production workflows. From raw material smelting, high-pressure die casting forming, trimming, multi-axis CNC precision machining, deburring, surface treatment to pre-delivery air tightness testing, every procedure implements strict technical standards and layered quality control.

Detailed production process:

1. Raw material smelting and purification: Aluminum raw materials are melted and purified to reduce internal gas inclusion and minimize casting pores.

2. High-pressure die casting forming: Form integrated housings with complex internal runners through precision molds.

Trimming and rough finishing: Remove casting flashes, burrs and excess residual materials.

3. Multi-axis CNC precision machining: Complete hole machining, tapping and sealing surface finishing to guarantee assembly precision and sealing flatness.

4. Deep deburring treatment: Clear residual burrs inside air and gas flow channels to prevent flow channel blockage.

5. Surface anti-oxidation treatment: Implement sandblasting, anodizing or other surface treatments as required to enhance high-temperature oxidation resistance.

6. 100% air tightness inspection: Carry out full air tightness testing before finished product warehousing.

The standardized process system brings multiple core benefits to customers:

First, purified casting technology greatly reduces internal porosity of housings, effectively preventing fuel gas leakage and improving the overall safety of combustion equipment.

Second, precision machining ensures high flatness of sealing surfaces, achieving excellent fitting effect with sealing components and stable control of air-gas mixing ratio.

Third, flexible mold development and diversified material options support customers to develop differentiated combustion equipment and realize personalized product iteration.

Fourth, stable batch quality consistency reduces assembly rejection rate and post-market safety failures, saving after-sales maintenance costs.

Fifth, mature mass production balances quality and manufacturing costs, helping combustion equipment manufacturers optimize procurement expenses and strengthen market competitiveness.
