Many customers want to search shear studs suppliers from China. Some of them are the first time to sourse shear stud from China and they do not know how to choose reliable manufactures, such as raw material, quality control, packaging, delivery, payment terms, shipping, etc. Parts of them choose lower price but the quality cannot match their requirement.
And even the sample is ok but the bulk product is bad. Because there are too many bad suppliers give them very low price with low quality.

How can I find reliable shear studs from China?
Selecting suppliers is essential when source shear stud from China, as it concerns the quality and price of products. Raw material and producting machine(cold forging machine)are the two most important elements for shear stud importers, so I divide them into following three types:
Raw material
There are two types of raw material in China, SWRCH15A(it is also called ML15), SWRCH18A(it is also called ML18), the difference of chemical composition to lead to the mechanical properties difference.
SWRCH15A can product shear stud matching ISO13918:2008 after some pretreatment
SWRCH18A can product shear stud matching ISO13918:2008, AWS D1.1, AS/NZ1554, BS5400,etc
2.Factory of raw material
There are many steel factories to product mild steel in China.
Xingtai iron&steel copr.,Ltd is outstanding for producting shear studs.
3. Pre-treatment of Raw material
the raw material need to pre-treatment before cold forging. the scaale need be removed by a process called phosphating and pickling. however, phosphating is forbidden by the government because of environment protection. so now the drawing wire machine including pickling function is popular by the factory.
4. cold forging process
there are too many factories in China to choose low-cost cold forging machine to produce shear studs without chamfer.
Normally the chamfer depends on the mold of cold forging machine.
Only 3 die 3 blow cold forging machine could produce welding studs with chamfers.
there are two ways to clean oil after the shear stud by cold forging. one is by rotating the cylinder which is full of shear stud and sawdust together. the other is using new cleaning oil machine.
5.installing aluminum ball process
most factories in China install aluminum ball by hands.
Hebei Jinan fasteners still insist on producing high quality and moderate price to win the market. if you need source shear stud China, please do not hesitate to send email to us!
