Quality Control

As a professional hydraulic cylinder manufacturer with over 20 years of experience, CMG puts great importance on quality controlling of every link of production process and thus meets the requirements of customers. All hydraulic cylinders delivered to the customer are all strictly tested, including pressure testing, finish testing, hardness testing, ultrasonic testing, weld testing, paint layer testing, hydraulic oil cleanliness testing, etc. These strict quality control procedures help CMG to earn customer’s trust and recognition.

Pressure Test

All hydraulic cylinders we produced need to pass the pressure test before delivery. The testing pressure is generally 1.5 to 2.5 times than the working pressure. The test items include the following seven aspects:

hydraulic cylinder operation test
Minimum starting pressure test
Buffering effect test
Internal leakage test
Pressure-tight test
Full stroke test
External leakage test

Other Tests

In addition to pressure testing, other aspects must be tested for acceptable qualifications before delivery, such as cylinder tube and piston rod machining accuracy, weld bead strength testing and ultrasonic testing, piston rod coating thickness and hardness testing, hydraulic oil cleanliness testing, paint thickness and viscosity testing. The finished products of hydraulic cylinders will not deliver until all tested indicators meet customer’s requirements,
