Due to its valuable characteristics, Wujinmu makes the price of Wujinmu furniture on the market higher and its market share is getting bigger and bigger, but everything has its two sides, and Wujinmu can't be avoided. Below, Fuyuan Furniture introduces you to the advantages and disadvantages of Wujinmu?
First, the advantages and disadvantages of Wujinmu's advantages:
1, the material is rare: Wujinmu, special growth environment, growing in the soil surface rich in mineral resources, the average elevation of 1600 meters above the hills, the output is less and more precious than other wood.
2, the texture of Wujinmu is natural and beautiful.
3, Wujinmu natural wood color gold and black curve is obvious, the color is eye-catching and very fluid, any one of the cut surfaces can clearly show the beauty of wood grain. Moreover, Wujinmu has a low material rate, hard wood and difficult processing, so each product made with Wujinmu exudes a strong natural atmosphere.
4, able to go hand in hand with the wood grain, Wujinmu's wooden structure is very good. As long as you use a hand to rub a weight, you will find that Wujinmu is much more sinking than other woods. It is as hard as ash, eucalyptus, eucalyptus, and red oak. The hardness and density of the wood are similar, and the wenge wood in the lacquer wood domain is similar to the wenge wood, and the tube holes are fine, and the wood grain is intertwined to form a solid texture.
Second, the advantages and disadvantages of Wujinmu are the disadvantages of Wujinmu:
1, Wujinmu's moisture content changes make it easy to deform and crack, can not adapt to the cold or overheated, dry and humid environment, so the use of special needs to avoid the environment of too cold or too hot, so as not to damage the wood.
2, Wujinmu is not only unique in texture, but also irritating in temper. In the process of drying and processing, it often bursts in shape, because it is designed according to the condition of cracking, not mass production, so each piece is Unique, there is a sense of collection.
3, if Wujinmu is not handled properly or the process is not closed, the wood will be prone to decay for a long time, and the wood color will fade.

Although there are many types of tapping screws, they all have the following similarities:
(1) are generally made of carbonized carbon steel (accounting for 99% of total production). It can also be made of stainless steel or non-ferrous metals.
(2) The product must be heat treated. Carbon steel tapping screws must be carbonized and stainless steel tapping screws must be solution hardened. In order to make tapping screws to meet the requirements of the standard of mechanical properties and performance.
(3) The product surface hardness is high, the core toughness is good. That is, "soft inside strong outside". This is a major feature of tapping Screw performance requirements. If the surface hardness is low, it can not be screwed into the matrix; If the core toughness is poor, a twist will break, can not be used. So "inside soft outside steel" is self-tapping screw to meet the use of performance, very important requirements.
(4) The surface of the product needs surface protection treatment, generally electroplating treatment. Some product surface must be treated by phosphate (photostatting), such as wall panel self - tapping screws for photostatting.
(5) Production by cold heading process. It is recommended to use high-speed cold heading machine and high-speed wire rolling machine or high-speed planetary wire rolling machine. High speed is emphasized here to ensure product quality. Only the head of tapping screw produced by high-speed machine is well formed and the thread quality is high.
