1、设计时应根据使用条件，金属冷挤压成型液压机正确的选用接头和密封的类型，确定密封圈的材料，合理的设计密封沟槽的尺寸、规定恰当的加工要求，是保证密封有效的前提。
2, the assembly should attach great importance to the metal cold extrusion molding hydraulic machine sealing parts and the cleanliness of the sealing ring, and according to the provisions of the method for the correct installation, to prevent the hydraulic machine sealing ring in the assembly of damage.
3. All kinds of pipe connections are the main parts of the external leakage of the metal cold extrusion molding hydraulic press. Therefore, the number of connecting parts such as pipe joints should be minimized in the design.
4, sealing parts of the groove, groove, surface processing size and precision, surface roughness should be strictly in line with the specification requirements, which is the metal cold extrusion molding hydraulic press to ensure the sealing effect of the basic conditions.
