How to solve the Staples heat treatment when the deformation problem
Staples fasteners are often heat treated during the production process. But many manufacturers in the product, especially the longer length of the Staples fasteners for heat treatment, there are often the phenomenon of product bending. So how to prevent the deformation of the heat treatment problem? Follow the Staples factory to see it:
First of all: in the production of Staples fastener products, it should be a reasonable choice Staples material, different Staples fasteners, different applications, different requirements should be fully considered.
Second: the product design should be reasonable, try not to be uneven, disparity is too large, and the product to be reserved for processing margin.
In addition: to eliminate stress, some sophisticated, high precision and complex products to be pre-heat treatment, a large degree of elimination of residual stress, while heat treatment to carefully monitor and control the heating temperature and speed.
Staples custom processing reminder: If you can, you can use vacuum heating quenching, as well as quenching after cryogenic treatment.
There are also a few other places to note, such as hand and neatly placed Staples, head and tail, tighten Staples procurement, can reduce the bending of the situation. Or the first heat treatment after rubbing teeth, rubbing teeth while rubbing straight method and so on.
Stainless steel Staples rust problem which, let us together with the Staples manufacturers to understand the next bar.
1, dust or heterogeneous metal particles attached to the moisture in the air, the attachment with stainless steel Staples condensate, the two together into a micro-battery, triggering the electrochemical reaction, the protective film is damaged, called the electricity Chemical corrosion.
2, stainless steel Staples surface adhesion of organic juice (such as melons, soup, sputum, etc.), in the case of water and oxygen, constitute organic acids, long time the organic acid corrosion of metal surface.
3, stainless steel surface adhesion containing acid, alkali, salt substances (such as decorative walls of alkaline water, lime water splash), causing local erosion.
4, in contaminated air (such as containing a lot of sulfide, carbon oxides, nitrogen oxide atmosphere), in case of condensate, the formation of sulfuric acid, acetic acid liquid point, causing chemical corrosion.
The above can cause damage to the stainless steel Staples surface protective film to cause corrosion. So, the metal Staples manufacturer, in order to ensure that the stainless steel Staples surface is bright and not rusted. We have to do cleaning on its surface. Passivation and other treatment.
Stainless steel Staples can be tailored to the needs of the product, but it is also necessary to use a few meters long long Staples. The world has produced a long 1.75 long Staples, is currently the longest demand for a user, of course, often have some 70mm, 120mm long Staples custom. ,
Stainless steel Staples have a better performance than copper Staples, Tita Staples, and it can be made very long in length. In the production of Staples, the choice of models is also important, Staples length, hardness can not keep up, It is likely that there will be a long stainless steel Staples bending phenomenon, so stainless steel Staples to lengthen the words, the general will choose 304 stainless steel.
Staples are mainly used for connection and fixing of some thin plate pieces, with strong corrosion resistance, stainless steel Staples processing plant, Staples manufacturers tell you Staples electroplating need to pay attention to what place.
1, Staples manufacturers tell you that under conventional plating conditions it is difficult to meet the various Staples plating quality requirements, so you need to buy professional tools to operate;
2, in order to put the Staples electroplated, so need large and tail wire such as metal Staples scoring to electroplating;
3, in order to prevent Staples damage, need to be relatively small Staples and relatively large Staples separate plating, to avoid thinking of the encounter.
