How to do a little bit of thought for hardware accessories business

The first stage: just when making the nut screw industry business, it is far from the previous industry. The first day to come, there is a guest come to consult the product, what nut, what specifications, what material to be sent to me, I look at the only understanding of the material, others do not know what is the meaning, do not know how to answer the guests? He can only ask his colleagues with a thick face and ask questions. He has been busy for a long time, not only has his order not come down, but he has been teased by the guests. I think it might be the first time to enter a new industry. It’s all about me. For the next few days, I didn’t sit there, 1), but looking at the content of our website. 2), while looking at the information of our company, when guests come to ask, they get everything from the above two channels. 3) the most important resource, of course, should not be wasted. It is our colleagues. Ask more, listen more. 4) in the age of information, resources on the Internet are also a channel for us to grow up. Many very good websites are all we can learn, such as Taobao, hardware net, etc., Baidu has one search.
The second stage: familiarity with product knowledge is a magic weapon
1, the first step is to first understand the material composition of the product, then what is the difference and what different materials adapt to different working environments.
The 2 and second step is to understand the product structure of the company, what products are our superior products, and what are they not?
For example, our company’s products, the main products, mainly material, 304316, the dominant products are: stainless steel pulling rivet nut, butterfly nut, butterfly screw, metal locking nut, flange nylon locking nut, flange metal locking nut, card type, K cap, nylon cover mother, welded nut, quadrisquare nut, long nut, burglproof Nut, anti-theft screw, internal expansion, knurled pin.
So when the guest asked me, I would have these information in my mind, which would screen out the products that meet the requirements of the guests and recommend them to the guests in time and effectively. In this way, the guest will admit your professionalism. Thus the single conversion rate is improved.
3, third, to be in contact with each other in time
Usually I send them my own micro signals, for example.
For example, a picture, a collection of products

It will enable our guests to understand our supply products well, and there may be a lot of contact ways.
Finally, in order to make our customers believe that we are real manufacturers, we have the ability to provide them with good products. I will also send a WeChat public address of our company: qbsyjgj, strong WeChat public address.

A two-dimensional code is added to enable our guests to understand our company’s dynamics every day and grow with us.

The above is a little experience that my little brother stepped into this industry, and I hope it will help you.

Change of metal craft gift

The earliest metal handicraft in China is a bronze handicraft unearthed from the ruins of the middle part of the Neolithic culture, such as the Ma Jia Yao culture, the Da Wen mouth culture and the later Qiao family culture. Gold craftwork appeared in the Shang Dynasty. During the Warring States period, there were many kinds of metal materials combined with metal and non-metallic materials (jade, colored glaze) made of handicrafts. The Han Dynasty could produce exquisite gold and silver wire knitted, stacked and inlaid products. The Tang Dynasty was the heyday of metal handicrafts, especially silver handicrafts, and created a gold and silver chisel chisel technology with relief effect. In the song, yuan, Ming and Qing Dynasties, because of the progress of smelting technology and the increase of metal materials, the metal crafts have developed greatly. There are not only a variety of metal and various materials and crafts, but also a variety of crafts. Ancient Chinese famous metal handicrafts include bronze ware of Shang Dynasty, gold and silver of Warring States, bronze mirrors and jewelry of Tang Dynasty, Xuan de stove in Ming Dynasty and cloisonne in Qing Dynasty. In the 70~80 years of twentieth Century, aluminum alloy, titanium, platinum and other metal crafts appeared, and the new technology of corrosion lacquer, titanium cathode oxidation coloring and negative oxygen ion plating were innovated. China’s metal handicrafts, such as Tibet, Mongolia, Miao and other minorities, are also famous. Production organizations in different historical periods are also different. In ancient times, metal handicrafts were mostly enjoyed by the nobility and aristocrats, especially precious metal handicrafts, which were monopolized by the palace handicraft industry. In the Tang Dynasty, because of the development of metal materials, folk production appeared. There was a silver shop in the Song Dynasty. The Yuan Dynasty’s folk production of silverware increased. In the Ming and Qing Dynasties, the two generation of folk metal handicraft was flourishing. The main form was the silver shop of the front shop and the factory. After 1950s, it was produced by factories and distributed by commercial departments.

What are the new structures of the taps?

In order to improve the cutting efficiency of the tap, improve the chip and chip removal situation, reduce the tooth breakage and break, the modern tap has many new structures. (1) screw tip tap: cutting part is worn with chute to form negative edge inclination (see cutting tool). Chip cutting forward is suitable for taper taper hole.
The spiral groove taps: the chip tank is spiral. In processing the right screw thread of the blind hole, the taps should make the right spiral chipping slot to make the chip discharge forward without scratching the thread.
Troughless extrusion Taps: the plastic deformation of metal is formed by the extrusion of the wall of the extruded hole, which is mainly used to process plastic materials such as aluminum alloy and copper, and also for processing low carbon steel and stainless steel. The cone end of the head of the taper is a conical thread. In order to reduce friction and reduce extrusion pressure, the taps section is made polygonal. The extruded tap has high strength and is especially suitable for machining small size holes with diameters below 6 mm.
(4) taps: grinding one tooth along the direction of the spiral line of the knife teeth, thus increasing the chip thickness, which is beneficial to cutting and removing chips, for the processing of stainless steel and other parts.
Content chip tap: chip is discharged from the inner hole of tap and used for machining large size screw holes.
Automatic shrinkage taps: after tapping, the tap teeth can automatically shrink in order to exit quickly.
Broaching tap: a broach with teeth distributed on the helix, commonly used for machining trapezoidal and square tooth threads.
Tungsten carbide tap: mainly used for processing cast iron and non-ferrous metals, cutting efficiency and tool life are higher.
