Dear XXX,
Good day!This is Ms Huang from Q.R. Precision Steel Ball Co., Ltd..
I ’d like to share a good new with you.First, let me introduce simply.
Q.R. is a leading precision steel ball manufacturer in China. Like many steel ball
manufacturers,we face a problem that existing sorting machines fail to meet actual
needs. In order to solve this problem, our engineers have researched since 2009,
finally a new generation of sorting machines come out!
As this series of surface detectors have been used to sort steel balls for more than 5
years by our customers, technology is very mature.
Let me provide its specific parameter as follows:
*Sorting Precision：G5 –G200
*Sorting Size Range：0.7938mm – 25.4mm(Divided into 6 ranges)
*Sorting Efficiency：4-7steel balls/sec.(14400-25200steel balls/hour)
*Sorting Material：bearing steel balls/stainless steel ball（Have developed）
*Sorting Material：ceramic ball（in developing）
*Sorting Medium：No （kerosene is not needed,save a lot of cost）
*Defects Detecting Ability: all scar defects deeper than 0.001mm will be detected.(controlled by user)
*Undetected rate:
Let me share some particular advantages with you:
A.When detecting,no medium is need,only use electric power,which keep factory in
a safe and clean environment.It is a technological breakthrough!There is no second
company produced such a machine in the world.
B.Special rollers can detect the head defect and different size products before
detecting surface,which is very different from traditional machines.
C.More quickly and easily to replace molds: using only your hands without tools,
while traditional machines need to be replaced by technicians with tools.
D.It ’s the first machine that can detect steel balls smaller than ∮2mm in
China.Others only detect steel balls bigger than ∮3mm.
E.Make full closed structure to keep away away from insects, dust and fiber.Support
WIFI remote control operation in 24 hours.
For more information and specifications,please contact me.Enclosed is information
about Q.R. Series Surface Detector.
Looking forward for your reply!
Thank you and best regards,
