Custom Aluminum Base Plates & Metal Castings
We offer high-pressure die-cast aluminum base plates—ideal as structural or decorative metal bases for lighting fixtures, machinery mounts, and architectural panels. Engineered for precision, durability, and attractive surface finishes, our bases combine the efficiency of die casting with optional CNC machining to meet tight tolerances and complex geometries.
Key Features
• High-Pressure Die Casting
– Cold-chamber machines (280–1,500 ton) deliver consistent wall thickness, minimal porosity, and near-net-shape accuracy.
• Premium Aluminum Alloys
– ADC12, A380 and other industry-standard alloys for optimal strength, corrosion resistance, and castability.
• Post-Process Versatility
– Secondary CNC milling, drilling, and tapping on 3- and 4-axis centers to achieve critical dimensions (tolerance to ±0.05 mm).
• Surface Treatment Options
– Anodizing (clear or color), bead blasting, powder coating, silk screening, and chemical passivation for functional and aesthetic requirements.
• Fine Surface Finish
– Achievable Ra 1.0–3.2 µm depending on mold polish and post-treatment.
