Crimping is a key process in the manufacturing process of rubber hose assembly. It is very important to strengthen the quality control and quality inspection in the process of clamping to ensure the quality of the hose assembly.

(1) Correct selection of clamping mold. When choosing the mold, it should not only be satisfied to reach the required diameter of withholding, but also take into account the size of the gap between the mold after withholding.

(2) Determination of compression size. According to the structure, performance and joint structure of the rubber hose to determine the compression rate, should be verified by the test, especially the first part of the test. According to the measured wall thickness of the rubber tube, the diameter of the jacket after compression is calculated according to the selected compression rate, and then the hydraulic test, the joint pulling test, to check the sealing performance of the rubber tube and the joint pulling strength.

(3) Strictly control the appearance quality of clamping. Pay attention to coordination and coordination, control the joint clamping positioning size, prevent the joint from being crushed and inaccurate clamping position. Try to avoid repeated withholding.
