Product Description
Engine oil pan oil plug
The engine oil pan oil plug was made for replace the engine lubricants oil ,when we replace the oil inside the oil pan normally we replace the oil plug also ,the oil plug alway come with the brass gasket.
Engine oil pan oil plug location
Key future of oil plug
The oil plug for rear engine oil sump was at the end of the oil pan ,so that it can easy to lead the oil out
1.The main function for the engine oil plug was keep the oil in seal position
2.When we replace the engine oil sump oil we need to take it off
The key future for the engine oil plug was seal for the engine oil pan
1.oil plug was working with the oil pan oil seat
2.Use the torque to keep oil plug seat and oil plug as same flatness to seal the oil leaking from the engine oil sump
Stamping Workshop
Cold forming for bolt and engine oil pan plug
The cold forming was one of the production process for engine oil plug
We put the wire coil onto the material delivery center,the wire was feeding by itself by the feeder .
Advantage of the cold forming :
Without heating to save some cost
Production keep on the stamping mold
Automatic production by itself
Application:QTY over 10000pcs once per PO
Cold heading machine
The first step for the engine oil plug was blanking and forming the hex head,normally we use two mold or four mold cold forming machine .To choose the oil plug oil bolt for different machine was depend on the QTY and length
Cold heading machine two mold
Four mold Cold heading machine
The two mold Cold heading machine was suitable for the long bolt also with big diameter
Four mold cold heading machine was working for the small bolt with small diametere
Thread workshop for engine oil pan bolt or cylinder bolt
The thread was made by Thread Rolling Machine ,normally the thread size for the oil plug was M12X1.5 with a brass copper to seal the oil from leaking
Some of the different size of the thread for the bolt was made by different thread wheel
The thread wheel was the key for the thread size ,normall we use the thread wheel to make oil pan oil plug in small qty
Heat treatment for the oil pan bolt
Most of the bolt oil plug for aftermarket oil pan didnot have the hardness,but the OEM one had the hardness HRC:32
That was why the oil plug need the heat treatment.
Heat treatment for the oil plug was the key for the seal ,because it need to make the oil plug seat flatness by torque
Why heat treatment
To increase the bolt Mechanical properties ,there were two ways
1.Use better raw material more than 40 Cr
2.Heat Treatment to improve the inside of the steel
Coating for engine oil sump oil plug
Coating was a key production process for the auto bolt ,especial for oil pan oil plug
When your car running on the way you didnot want your oil pan leaking or when you replace the oil you didnot want to see your oil plug rust inside the oil pan without moving
After the heat treatment for the oil pan oil pan or cylinder bolt ,we need to take care of the hydrogen embrittlement So before the auo bolt was put inside the cleaning washer tank we need to heat it up to release hydrogen
Mechanical performance test, tensile test
Mechanical performance test, tensile test was performance after the heat treatment .we need to know the bolt had the strength to reach the grade value we nee.
Salt spray test
Test prepare
salt water (5% NaCl) solution is atomized by means of spray nozzle(s) using pressurized air, first climate cycle comprises a continuous indirect spray of neutral (pH 6.5–7.2) salt water/synthetic seawater solution, which falls-out on to the specimens at a rate of 1–2 ml/80 cm2/hour
referred to in ASTM G85 as annexes A1 through to A5.Many of these modified tests originally arose within particular industry sector, in order to address the need for a corrosion test capable of replicating the effects of naturally occurring corrosion and accelerate these effects.
