1. Spray painting: Hardware factories use spray painting when producing large hardware products. Spray painting can prevent hardware from rusting, such as daily necessities, electrical appliance shells, crafts, etc.
2. Galvanisering: Galvanisering er også den mest almindelige behandling teknologi til hardware behandling. Gennem moderne teknologi, overfladen af hardware dele er galvaniseret til sikre at de produkterne vil ikke være mugne og rustne efter langtidsbrug. Almindelige galvanisering processer omfatter: skruer, stempling dele, batteri celler, bil dele, lille tilbehør, osv.
3. Surface polishing: Surface polishing is generally used for daily necessities. For example, we produce a comb, which is a hardware part made by stamping. The corners of the stamped comb are very sharp. We have to polish the sharp corners into a smooth surface, so that it will not cause harm to the human body during use. Turning the outer cylindrical surface is the basic method of outer cylindrical surface processing in hardware processing, and the equipment used is a lathe. In general machinery factories, lathes account for about 40% of the total number of machine tools. Turning is the main method for rough machining and semi-finishing of the outer cylindrical surfaces of various materials, and it is also the final finishing method for various materials that are not suitable for grinding. When single-piece small batch production is carried out, turning the outer cylindrical surface is generally carried out on an ordinary lathe. In large-scale production, multi-tool semi-automatic lathes or automatic lathes are widely used. Large disc parts should be processed on vertical lathes. Large long shaft parts need to be processed on heavy-duty horizontal lathes. The characteristics of turning the outer cylindrical surface are: simple tools, easy manufacturing, sharpening and installation; stable cutting process, small fluctuation of cutting force, which is conducive to the use of high cutting speed and improved productivity; good versatility of machine tools, can process outer circles, end faces, inner holes, threads and chamfers in one clamping. The relative position accuracy between the surfaces is easy to guarantee; suitable for the finishing of non-ferrous metal parts.
