Category: Machinery Parts and Components / Hydraulic and Pneumatic Components / Hydraulic Cylinders
Characteristics
(1)Based on a clients 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 satisfied (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
