Watches Workmanship Differences Between Stainless Steel and Alloy Watches
Currently, the watch is mainly made of stainless steel and zinc alloy. All-steel case means that the finishing and back covers are made of stainless steel. This material is polished to silver grey colour, and without adding the decorative rust-proof coating. Its advantage is not easy to rust, and it can still maintain its original colour after being used again. Some of the round cases in the market are made of this material. However, because of the high cost and slow processing of stainless steel watches. These watches are generally more expensive and it mainly uses for some high-end watches.
Zinc alloy case refers to the case made of alloy material, the surface is plated or sprayed with a layer of anti-rust, wear-resistant metal layer. The back cover is usually made of stainless steel. This is because the back cover is often in contact with human skin. Avoid sweat secreted by the skin will corrode the metal surface. Stainless steel is resistant to corrosion.
Watches Workmanship differences of alloy case due to the decorative rust-proof wear layer. So that can not plat too thick. Additionally, after a period of time, the case surface will be uneven wear. There are partial peeling and surface colour inconsistencies, which greatly affect the appearance of the watch. Although zinc alloy watches also have many deficiencies. Because of the low price, fast processing, low technology. So, there are many companies used to make gift watches, promotional watches and so on.
Watches Workmanship differences–Different watch process
Stainless steel case material watch is the most popular watch material in the market. But because the production process is cumbersome and the material processing is relative complicate.
So, there are many people want to make a stainless steel watch. But, they do not have enough time for the watch production. Hence, some high-grade watches that led to stainless steel resulting in a low-grade effect.
As the saying goes, there is a lot of good things. An exquisite watch is this truth. What is the stainless steel case production process?
First, the watch production factory will open moulds according to the design drawings of the watch, and then review the moulds. Then raw materials will be explanted.
After the embryos are completed, they will enter the shape of the garage, and drill holes into the drill house (the tube holes, deep ears, and press Holes). And to mill a variety of process effects. And then the watch production factory and then finishing polishing. Then transferred to the electroplating factory electroplating various colours after the packaging to the assembly department assembled into finished products. This is the common production process of the stainless steel case.
Watch Workmanship differences of Stainless steel case manufacturing process
1) blank cold-formed stainless steel plate colour silver white.
2) Embryo colour before processing Silver.
3) 2 kinds of processing colour silver white, drilling machine processing.
4) CNC lathe precision machining colour silver-white vertical CNC machining center (CNC).
5) Waterproof finished product colour silver.
Watch Workmanship differences of The alloy watch manufacturing process
1) Grinding material into mould castings.
2) The initial embryo of the case is grey, the blank enters the die zinc alloy hot chamber die casting machine.
3) After finishing polishing.
4) Plating/painting Change colour as needed, spray paint production line.
These two processes are the specific requirements of the case. This is two different processes, and it has heavy pollution to the environment.
5) Finished Plating PNP Color Silver.
There is no waterproof test of the alloy because the alloy itself is the cast. There are many bubbles inside the shell. Hence, it can not pressurize.
Environmental Health & Safety
Nowadays, gold, silver, alloy, and brass are dominating the jewellery & watch market. However, stainless steel is quickly growing as a preferred material. The best quality of stainless steel is 316l stainless steel. Its Mo content makes the steel has the excellent anti-pitting ability.
It can safely apply to the environment containing halogen ions. Such as Cl-. 316l stainless steel is also a derivative steel belonging to 18-8 austenitic stainless steel, and with 2 to 3% Mo added. On the basis of 316L, there are many kinds of steels. Such as 316Ti after deriving a small amount of Ti, 316N after adding a small amount of N, and 317L deriving from the increase of Ni and Mo content.
Since the main application of 316l stainless steel is chemical properties. The surface inspection requirements of 316L steel mills are lower than 304. And surface inspections is required for customers with higher surface requirements.
316L stainless steel also has the following advantages:
1) The appearance of cold rolled products is good and beautiful;
2) Due to the addition of Mo, the corrosion resistance, especially the resistance to pitting corrosion is excellent;
3) Excellent high-temperature strength.
4) Excellent work hardening (weak magnetic after processing).
5) Non-magnetic in the solid solution state.
6) Durability. Stainless steel is a very strong metal. So it is more likely to hold its original shape for a lifetime.
7)Not easy allergy. Compared with other metals, stainless steel is unlikely to cause any reaction at all. So it is the safest choice for sensitive people.
8) Affordable. It relative to 304 stainless steel, the price is higher. But, compared with gold and silver. Hence, this the best way to saving more money and keeping your life simply.
