THE ROLE OF ALUMINUM POLISHING IN MANUFACTURING
Aluminum polishing process aims to remove defects on aluminum surface and increase the brightness to the required level. Common aluminum workpieces that need polishing are rough casting workpieces (with burr, mold marks, scratches, gas porosities, blowholes) or oxidized workpieces whose surface colors have gotten dull. After the metal surface treatment & polishing process, aluminum surface will meet high demand for outer appearance, which enhances product value.
Aluminum polishing enhances the value of aluminum products
Not only is manual aluminum polishing method time-consuming and costly, but it also does not satisfy increasingly sophisticated requirements for surface result. Nowadays, most manufacturers choose to conduct aluminum polishing via specialized machine with surface active preparations instead of manual polishing. By this way, surface quality and polishing quality are greatly enhanced, while working time and costs are noticeably reduced.

ALUMINUM POLISHING METHODS BY MACHINE
Aluminum polishing can be conducted via wheel grinding machine or 3-dimensional vibratory machine. Both of these methods are semi-automatic, which means they still require workers in order to operate.
Wheel grinding machine polishing: polishing via wheel grinding machine using buff wheels/felt wheels/flap wheels/sisal wheels and specific polishing compounds according to requirement.
Polishing via wheel grinding machine and polishing wheels
Vibratory & Rotary machine polishing: polishing via specialized machines such as 3-dimensional vibratory machine and rotary barrel machine. Worker fills the machine with media, specialized surface active preparations, water and the workpieces before starting the process. After the workpieces surface meets the requirement, they shall be taken out and cleaned with water.
Vibratory and rotary machines can deburr rough aluminum workpieces (rough polishing), polish and finish the outer color (fine polishing) according to each specific demand by choosing different polishing media.
3-dimensional vibratory machine
Aluminum polishing process can be broken down into 3 steps: rough, medium and fine polishing. The optimal polishing process depends on the condition of the unpolished workpiece and polishing requirements. A rough aluminum casting workpiece coming straight out of the mold normally has burrs that need to be removed via vibratory machines. Depending on the polishing requirement, the next step can either be medium or fine polishing. Normally, fine polishing via grinding machines with buff wheels, felt wheels and polishing compounds is the last step, which helps to enhance the surface brightness.
SPECIALIZED ALUMINUM SURFACE ACTIVE PREPARATION
LEKAR has researched and provided specialized surface active preparations for aluminum vibratory and rotary polishing in order to ensure time effectiveness, desired brightness and color. Porcelain and stainless steel balls used during fine polishing by vibratory and rotary barrel machines bring out pure and deep-shaded brightness as per request.
