Hydraulic Jack - Jis G4105 Scm440 Material, Precision Dimensions +/- 2~4mm, Enhanced Durability And Hardness Through Heat Treatment, Oxy-acetylene Welded Copper, Electroplated Piston And Cylinder | Superior Load Capacity, Reliable Performance

Following Details of Hydraulic Jack :

Manufactured by process :
(1) Based on a clienta s requirements, we make an offer of a hydraulic product, giving its actual dimensions
and loading capacity .The offer is discussed with the client to ensure that their requirements are atisfied
(this is not necessary if the client provides drawings and specifications).
(2) Procurement of raw materials as per specifications of JIS G4105 SCM440.
(3) Boring the material (the raw material being solid).
(4) Rough machining to a +/- 2 ~ 4mm precision in dimensions, followed by heat treatment to re-adjust
material characteristics.
(5) Heat treatment to machine workable range . The heat treatment increases the hardness and durability
of the material, lengthening its service life .
(6) Welding the copper, which can be done in three ways : (1) oxy-acetylene welding of copper, (2) gas
metal arc welding of copper (GMAW), and (3) CO2 welding. Our factory uses oxy-acetylene welding of
copper, which is the most expensive method , but yields the best results.
(7) Fine machining (boring, threading, lathe processes)
(8) Filling up the holes, grinding.
(9) Electroplating the piston and inside of the cylinder (to increase the hardness of contact surfaces).
(10) Verify the serial numbers, then assemble the various parts (including sealing rings)
(11) Testing.
