Metal processing and polishing are significant for most industries. Therefore, when choosing a metal processing facility in Hanoi for polishing services, customers need to consider the reputation and quality of the provider carefully.
1. Methods of metal polishing
Polishing is the final step in the metal processing workflow. It determines the aesthetics and the quality of the product by smoothing surface imperfections and creating a glossy finish. All metal products need to undergo polishing to meet the required standards before being sold on the market.
Metal polishing is the final stage in the metal processing workflow.
Metal polishing methods are divided into two main types:
1. Polishing with vibratory machines or barrel finishing machines: This method is used for all three stages of polishing – rough, medium, and fine. It uses abrasive stones and chemical solutions to polish metal products.
2. Polishing with mechanical machines: This involves using mechanical grinders combined with abrasive materials such as felt pads, abrasive wheels, cloth wheels, coconut fiber wheels, and so on. This method is applied for polishing from deburring to mirror finishing.
Metal polishing is categorized into rough polishing, medium polishing, and fine polishing. Depending on the aesthetic requirements of the metal product, manufacturers need to choose the most suitable polishing metho
2. Products obtained after metal polishing
Raw metal products with sharp edges need to undergo deburring using a vibratory machine and a specialized deburring solution. The abrasive stones, solution, and the metal parts are mixed together, creating friction that smooths and rounds off the sharp edges. The resulting metal products have rounded, smooth edges, making them safe for handling.
Metal products with rough surfaces need to be ground using abrasive stones and specialized solutions in a vibratory polishing machine. The friction between the abrasive and the solution removes surface irregularities and protrusions. After this process, the metal products have a smooth surface with a relatively bright finish, making them suitable for painting or plating.
Metal products before and after polishing
For products that require both a smooth surface and a high gloss, all three polishing stages – rough, medium, and fine – need to be applied. Rough and medium polishing are performed using vibratory machines, abrasive stones, and polishing solutions, while fine polishing to achieve a mirror finish is done with mechanical grinders combined with cloth wheels and polishing wax. The metal products obtained after fine polishing are not only smooth but also highly reflective. These typically include items such as door handles, kitchen utensils (spoons, forks, bowls, plates, chopsticks, knife blades), sanitary equipment (shower heads, cup holders, mirror racks), and many other items.
Typically, manufacturers can either complete the polishing process in-house by purchasing machines, abrasive stones or media, and polishing solutions or wax, or they can send their products to reputable and experienced metal polishing service providers for professional support.
