GENERAL INSPECTION
RAW MATERIAL INPUT
Every lot of input of raw material should be inspected through composition
analysis and taking record of all the data for study.input meets with our Q.C request.
BLADES PRPCESS INSPECTIONS
Tips:
we check the tip size by DIN standard gauges. Measuring important
point of sizes in Thickness, Width and Length.
HEAT TREATMENT INSPECTIONS
1. Hardness testing:
Blades must be proceeded as Heat Treatment till the hardnedd
allowance within HRC+/-1.
2.Torque testing:
We are able to control the torque of the blade over DIN standard
more than 30% which made by chrome-molybdenum steel.
STRAIGHTENING
To ensure
all blades are straight after heat treatment
We do straightening and test by the same machine at the same time.
PLATING INSPECTIONS
In order to
ensure the resistance to erosion after plating
we do Salt Spray Testing and also check appearance color of plating.
IMPACT TESTING
The testing
is
based on two conditions
1.Normal Temperature:
23℃
±5℃, H=W/P=2FP
2.Low Temperature:
-25℃
±3℃, Stay in the fridge more than 2 hours, (H=W/P=0.6FP)
select 3 points of the blade be impacted.
FINAL INSPECTIONS
After
the blades are assembled with handle, we start to do final inspection before
packing and shipping out which are as:
1.Check
straight line between blade and handle
2.Ensure
the
handle is clean
3.Magnetize
all blades.
TECHNOLOGY
We finish our tip in Black or Normal per you request andguarantee the high precision
with resistant erosion. Magnetization is one of our standard processes for each
item.
The raw materials we used as below:
A. S2 Steel
Optional material by customer's request
Hardness:HRC 58-60
Torque: Up 10% from Cr-Mo
B. Chrome-Molybdenum Steel (Cr-Mo Steel)
Our Standard offer
Hardness: HRC 54-56 (Slotted HRC 52-54)
Torque: Up 30% from Cr-V
C. Chrome-Vanadium Steel (Cr-V Steel)
Optional material
Hardness: HRC 50-52
Torque: meet DIN
VDE INSPECTION
VDE Inspections
TESTING PROCESS
High Voltage Testing
"Quality has no Compromise"
Especially for VDE 1000V Insulated Screwdrivers. We test our insulated Screwdrivers
piece by piece on our High Voltage Testing Machine. During the testing, the voltage
must be 12,000 V ~ 13,000 V.
Impact Testing
The testing is based on two conditions:
1.Normal Temperature:23± 5℃, H=W/P=2FP
2.Low Temperature:-25± 3℃, stay in the fridge more than 2 hours,
(H=W/P=0.6FP) select 3 points of the balde to be impacted.
Pull Testing
Pulling Insulated Screwdriver on the pulling machine with 50 Newton tester.
Fire Testing
The testing samples put on the fire with 3.7 Million Joule/㎥ 10second then turn-off
the fire. The height of burning can not over 120mm.
AUTHENTICATION
E-mark apply for VPA/GS certificates & approval for factory audit of decades.
Also we make full range of VDE insulated tools of Screwdriver / Pliers. We insist
to keep the good reputation of continued quality maintains.
