Electrophoresis Aluminum Extrusion
The Electrophoresis Aluminum Extrusion is manufactured by Shanghai Huishuo Aluminum Industry Technology Co., Ltd, a China based industrial aluminum profile manufacturer operating three production bases in Shanghai, Anhui and Jiangsu covering approximately 30000 square meters. The profile surface is finished through an electrophoretic coating process, in which the profile is immersed in a coating emulsion and an applied electric current deposits a resin film across the surface before curing. Production combines extrusion, custom mold making, CNC machining, electrophoretic coating and assembly within a single supply chain.
Electrophoretic Coating Process
Electrophoretic coating deposits a resin film onto the aluminum surface through an immersion process controlled by an applied electric current.
Pretreatment
Profiles are cleaned and chemically pretreated to prepare the surface for coating deposition.
Electrophoretic Deposition
Profiles are immersed in a coating emulsion bath, where an applied electric current deposits a resin film onto the surface.
Rinsing
Coated profiles are rinsed to remove residual emulsion from the surface before curing.
Curing
Profiles pass through a curing oven where heat cross links the deposited film into a finished coating layer.
Core Advantages
Uniform Film Deposition
The electric current used during deposition supports even film coverage across recessed and exposed profile surfaces.
Controlled Film Thickness
Coating film thickness is monitored during processing to meet the specified range for a given order.
Clear and Colored Finishes
Electrophoretic coating is available in clear, bronze and black finishes for custom profile orders.
Integrated Coating Line
Extrusion, mold making and electrophoretic coating are carried out within facilities operated by Huishuo Aluminum Industry.

Application Scenarios
Considerations Before Ordering
Coating film thickness and color reference should be confirmed at the drawing stage, since electrophoretic coating parameters are adjusted according to the specified finish and target film thickness. Profiles coated in separate production runs may show minor tone variation, so components used together in a single visible installation should be coated within the same batch.
Frequently Asked Questions
How is the coating film applied to the profile surface
The profile is immersed in a coating emulsion bath, and an applied electric current causes resin particles in the emulsion to deposit onto the grounded profile surface.
What color options are available for electrophoretic coating
Coating is available in clear, bronze and black finishes, selected according to the color specification provided with the customer drawing.
What is the typical coating film thickness
Standard coating film thickness ranges from 15 to 25 micrometers, measured after the curing stage of the coating process.
Can custom profile shapes receive an electrophoretic coating
Custom mold making supports special cross sections, which are then processed through the same electrophoretic coating line used for standard profile shapes.
