Stainless steel processing technology
Polishing is a kind of processing technology on the surface of stainless steel. We have two kinds of surface treatment which is satin and polished finish. Satin brushed is to make the surface of stainless steel produce regular line feeling, and the mirror is to make the stainless steel surface as clear as the mirror
There are also two kinds of polishing process we commonly used.
1.Automatic polishing: good smoothness and brightly surface, high production capacity ,but high pollution levels. simple work piece , small and medium-sized products can not be processed ,gloss reduced, high investment and cost and the gloss can not remain a long time.
2.Hand polishing: for polished finish, it can remain a long time and also suitable for complex workpiece and high grade small and medium-size products, easy to operate. And process is stable which the gloss can remain a long time, the products can be mass production. Less pollution and low cost, it can be widely used.
There are five steps to process with our 304# stainless steel products: firstly we use 80# (or 60#) sand belt to remove the surface, then use 100# sand belt to make it flat, then use 180# sand belt to make the surface smoothly, 300# sand belt to bring out the gloss, and finally use sponge wheel to remove the sand hole. And for the polished products, on the basis of 3 times sand belts, and use 2160# sand belt to make the surface smoothly, then use hemp wheel (add purple wax) to remove sand hole and scratches, again use cloth wheel (add green candle or white wax) to bring out the gloss. Our satin finish products look bright, and there will not have sand hole from visual inspection within 300mm. The service life of polished finish products will be one year longer than satin finish products. it passes through high temperature evaporation and the acidity and alkalinity in the wax is sealed, high resistance to acid and alkali.
Both hand and automatic polishing have their own advantages and cannot be replaced, so we use the combination of automatic polishing machine and hand polishing. This makes our stainless steel closer to perfection.
Milling machine is used for machining hardware with a milling cutter, mainly by the rotation of the milling cutter, grooving and drilling the surface of products. Huajian Metal Products CO.,LTD is using instrument milling machine to process with professional machining hardware accessories, and we also combine with CNC numerical control machine, which can produce a variety of products. So we have great advantages in customized products.
CNC is a kind of numerical control machine, which can simply the procedure of processing; making a stable quality, and improve the accuracy of processing.
Ultrasonic cleaning is an necessary step before assembling the products. When we processing the stainless steel hardware, we need use the cutting oil, so it will lead to the oil will remain inside of the products, and simple cleaning can not cannot completely clean it. These stains will affect the appearance and use of the product, then we will use ultrasonic cleaning machine to clean these stains and impurities.
Ultrasonic cleaning is superior to common cleaning, especially to the complex, irregular and perforated products, using ultrasonic cleaning can reach the ideal result. We will also add stainless steel cleaning powder into it, which is more efficiently to remove the stubborn stains on products' surface, and make the stainless steel products more brightly.
How do we ensure accuracy of custom hardware?
Our factory is equipped with advanced modern CNC machines capable of processing custom hardware, offering a high accuracy of ±0.01 mm.
Handles are manufactured with the following tolerances:
1.Total length: ±0.5mm
2.Center-to-center distance: ±0.3mm
3. Balance correction: ±0.3mm
For sliding door systems, strict manufacturing standards are strictly followed to achieve ±0.1mm tolerance.
In addition, we utilize custom jigs and fixtures in the manufacturing process, which can lock hardware components in optimal positions and ensure each piece of hardware maintains consistent size, shape, and positional accuracy.
Finally, after machining, we perform a dimensional inspection to ensure all products meet the ±0.1mm tolerance.
