  The first entry into the Shi Shi Tong screw supplier company experience Today is the fourth day of my entry into the Shi Shi Tong  screw supplier . Of course, if I remove the Mid-Autumn Festival holiday, I am going to work the next day. When I first entered a new family and a new environment, I was always a bit strange at first, but what made me feel warm was that my colleagues were very warm and kind to me, especially with Mrs. Song, who always taught me. Do every detail in your work. She told me that we must be careful when doing our job, be careful, or it is easy to make mistakes. And be sure to follow the process, otherwise, the next step or even the last step of the staff can not work very well, will bring some unnecessary trouble to others. To be honest, I used to be a company sales and personnel. Even if I have accumulated a lot of experience, I really don’t know much about our company’s business. All the knowledge about the company’s business and the c...

  Stainless screw in the production process, is it necessary to passivate? We all know that stainless steel has abilities in oxidation resistance and corrosion resistance. In many environments, it can be directly exposed to the air, so why will there be customers requiring  stainless screw  to do passivation treatment? Is that really necessary? Although  stainless screw  has a strong rust resistance, in some particularly harsh environments, it still will rust. Therefore, in order to improve the rust resistance of screws, it is necessary to carry out a passivation treatment.   Under normal circumstances, passivation treatment is at room temperature with passivation solution to soak the screws cleaning for 15 minutes, and then heated to 60 degrees or so soak for 15 minutes, such as the liquid into red, the treatment is completed. Passivation treatment can increase the salt spray test time by 12 hours, and can effectively improve rust resistance. In addition t...

  machine screw suppliers introduces you to the screw thread The difference between mechanical screws and other screws can be based on whether he can be used with a nut.  machine screw suppliers  are supplied with nuts. Compared to the screws of other teeth, there are self-tapping screws. Self-tapping screws it is an unneeded nut for assembly. As for the standard thread and the fine thread, the thread distance is different. It is the nut of the machine screw. Non-self-tapping screws are machine thread screws, that is, the workpiece to be fastened by the screw must be tapped in the screw hole with a tap to match the thread. The  machine screw suppliers  also want to tell you that according to the thread type, it is divided into ordinary thread, pipe thread, trapezoidal thread, rectangular thread, and zigzag thread. In addition to the pipe thread, the metric thread is used in China. Another type of mechanical thread is called a rectangular thread (the thread shape...

Recently, many provinces have experienced power outages, such as Guangdong, Jiangsu, Zhejiang, and Northeast China. Electricity curtailment has a great impact on the manufacturing industry. The production capacity of factories cannot be guaranteed. The original delivery date may be delayed. Will it also affect  stainless screw suppliers ? Electricity curtailment also has an impact on  stainless screw suppliers . Especially in the power-cut area, the scheduled production of the product is very affected. Even if it is always in production during the time without power-cutting, many orders cannot be delivered according to the original schedule. And areas that are not limited by electricity will also be affected, because raw materials, surface treatments, etc. are not necessarily produced in areas that are not limited by electricity. In the production link, as long as one is affected, it will affect the entire link. This is interlocking. Moreover, there is currently no guarantee t...

Shi Shi Tong is a screw manufacturer specializing in non-standard shaped screws and long screws. Since the opening of the online business, the inquiry of copper screws is not without, but it is rare compared to stainless steel screws and carbon steel screws.

After seeing Mr. Yao’s drawings, Shi Shi Tong screw manufacturers know why many screw manufacturers can’t produce them because the screws are too long, and the thread diameter is too small. The copper wire is soft, and the length of t...

When a company wants to find a hardware  screw supplier s  to customize the screws, be sure to polish your eyes. If you choose some technologies but are not responsible for the small factory, then you will definitely not find the same screw supplier. Screws, this is also human nature. In fact, many companies have chosen to buy a lot of hardware suppliers, but they don’t know. The small hardware screw suppliers are simply looking at the drawings and then making quotations. They have not communicated carefully with customers. I think I am professional, ignoring the actual use of screw fasteners, a large part of the hardware screws made, can not meet the needs of actual use. When a company develops new products, which hardware  screw supplier s  to choose is the key to whether your design and development effects can reach its limits. There is a supplier of such hardware screws in Shenzhen, they pursue quality and try their best to satisfy customers. This is the Shi Shi ...

At present, there are large and small screw manufacturers on the market, and they all have screws that are good at production. However, if it is a relatively small screw, there are not many people to use, and there are not many manufacturers that can be produced. For example,  machine screw suppliers  can produce screws with a length of 1500mm. Does this exist? In Shenzhen, Guangdong, there is such a screw manufacturer – Shi Shi Tong screw manufacturers. Shi Shi Tong  machine screw suppliers  mainly produce long screws. Many of their counterparts will process them at Shi Shi Tong screw manufacturers when they receive orders for long screws so that Shi Shi Tong can make semi-finished products or products for them. Orders for long-term screws accounted for 69% of Shi Shi Tong’s long screw orders. At present, the representative long screws produced by Shi Shi Tong  machine screw suppliers  are M6*1680mm.

On the Internet, we can often see different sellers selling the same product, their prices are different. And  screw supplier  is also so, different manufacturers in the quotation, the price is not the same. Why is this? screw supplier The main reasons for the uneven price of screw supplier   are: First, the area. Different areas, cities, their labor, processing costs are different. And different areas, the wire used in the composition may have to write in the difference, and the price will also have a difference. Second, the process is different.

And they are different craft price is different. screw supplier The wire diameter used is different. Some  screw supplier ...

On October 20, 2018, the annual five-region  screw  association meeting was held at the Sapporo Prince Hotel in Japan. Representatives from various regional associations gave detailed reports on the status quo of the screw industry in this area. The general association Japan Screw Industry Association – International Commissioner Da Chuan Keliang reported on the fastener industry in Japan: The real growth rate of Japan’s gross domestic product (GDP) in the first quarter of 2017, from January to March 2017, increased by 0.3% from the previous quarter, reaching a five-quarter continuous growth. It is speculated that this is due to a 2.1% increase in exports over the previous quarter, external demand driving growth rates, and residential investment and equipment servitude increased over the previous year. The GDP for 2017 is expected to be 553.5 trillion yen, an increase of 1.5% over the previous year. It can be seen that the  screw  industry is in the asce...

First, let’s first understand the passivation mechanism of the  screw : we know that iron and aluminum can dissolve quickly in dilute HNO3 or dilute H2SO4, but the dissolution in concentrated HNO3 or concentrated H2SO4 almost completely stops. Carbon steel is usually very easy. Rusting, if an appropriate amount of Ni and Cr are added to the steel, it becomes stainless steel. The phenomenon that the metal or alloy is affected by some factors and the chemical stability is obviously enhanced is called passivation.  Metal passivation caused by certain passivating agents (chemicals) is called chemical passivation. For example, concentrated HNO3 concentrated H2SO4, HClO3, K2Cr2O7, KMnO4, and other oxidants can passivate the metal. After the metal is passivated, its electrode potential moves in the positive direction, causing it to lose its original characteristics.  For example, the passivated iron cannot replace the copper in the copper salt. In addition, the meta...
