Hongming Sheng provides custom metal surface finishing for CNC parts, sheet metal components, aluminum housings, industrial assemblies and OEM metal products.

Available processes include powder coating, anodizing, sand blasting, brushing, polishing, electroplating, hot dip galvanizing and passivation.

Powder Coating

Durable protective finishing for sheet metal enclosures, cabinets, frames and industrial equipment.

Aluminum Anodizing

Anodizing improves corrosion resistance and appearance for aluminum CNC parts, housings, heat sinks and precision components.

Sand Blasting & Bead Blasting

Sand blasting and bead blasting create a uniform matte texture and can prepare metal surfaces for additional finishing processes.

Brushing & Polishing

Brushing creates a directional hairline texture, while polishing provides a smoother and more reflective appearance.

Electroplating

Electroplating can improve corrosion resistance, conductivity, wear resistance and surface appearance.

Hot Dip Galvanizing & Passivation

Hot dip galvanizing provides heavy-duty zinc protection for carbon steel structures, while passivation improves corrosion resistance and surface stability for stainless steel parts.
