In modern home appliances, the iron base plate is a critical functional component. It must ensure uniform heat transfer, maintain dimensional stability under thermal cycling, and integrate seamlessly with heating elements and protective coatings. Traditional stamped or machined bases often fall short in thermal performance and long-term durability. Die casting, particularly with optimized aluminum alloys like AC8A, offers a one-piece solution that combines structure, conductivity, and finish compatibility.
AC8A aluminum alloy provides a strong balance of thermal conductivity and mechanical strength, making it highly suitable for iron base applications. With excellent castability and superior heat resistance compared to A380 or ADC12, AC8A ensures stable performance under repetitive heating and cooling cycles. Its enhanced anodizing response also allows for durable surface protection critical in steam and dry ironing environments.
Using custom aluminum die casting, we produce complex soleplate geometries with consistent wall thickness and controlled surface topology. Molds are engineered with thermal balance to maintain flatness and minimize internal stress during solidification. Final wall tolerance is maintained within ±0.1 mm to ensure base uniformity for efficient heating distribution.
Key zones—such as heater interfaces, screw bosses, and vent channels—are finalized through CNC machining. These operations achieve sub-0.05 mm flatness for optimal heater contact and sealing surfaces. Machining also ensures high consistency for steam path geometries and precise sensor mounting points.
Initial sand blasting produces a uniform matte surface with Ra 2.0–3.2 μm, enhancing adhesion for subsequent anodizing. The anodizing process delivers a corrosion-resistant oxide layer while improving wear resistance and thermal stability. Anodized finishes also prevent discoloration from continuous thermal exposure.
