In recent years, the manufacturing industry is moving toward automation standardization development, mainly used in the dispensing needle dispensing machine, glue coating work performed a variety of different needs, so in object bonding, electronic packaging and other aspects will see the dispensing, stainless steel needles is a commonly used dispenser dispensing needle and its durability have strong corrosion erosion characteristics, whether it is what kind of dispensing function support equipped with stainless steel needles, some users on the market to buy stainless steel needles of inferior quality, directly affects the quality of dispensing work, so users should be how to identify high-quality stainless steel needles manufacturers?
Many types of stainless steel, mostly 302 or 304 stainless steel material, there are some dispensing needle manufacturers in order to save the cost of production, the use of 201 stainless steel making needles, stainless steel does not rust is mainly high nickel content, how nickel content can use stainless steel needle detection reagent dispensing proper amount. If nickel content is very low it is easy to rust after a period of use, directly affect the quality and consistency of dispensing.
Stainless steel is an important reagent reagent specifically applied to the detection of stainless steel, with quick test, simple operation, obvious effect and work characteristics, when using the reagent dispensing needle is coated on the surface, if the needles turn red indicating needle rust resistance is poor, effectively help users to detect whether the material qualified stainless steel needles.
According to the actual situation of the needs of the user can select more different kinds of needles, no need to use limited to stainless steel needle, you can choose a Teflon needle and screw needle, flat needle etc..
