Monkey Wrench Production Process

Firstly, the raw materials need to selected carefully, all arrived materials will undergo dimensional and chemical analysis, after checked already the raw materials. Steel bars will be cut into sections, then the pieces are cleaned in a sandblaster to remove all steel impurities that may enter into the metal during following step.
Now the cut pieces will under go hot rolling and hammer molding, then they will be loaded into an automatic elevator, the pieces will be heated up to 1250 degrees one by one in an induction furnace. In this way the original tough and resistant pieces become malleable, and shape into a desired form, the hot rolling mill then gives each piece an elongated shape. And then direct the pre-shaped pieces into an impact machine to compress the hot material between two molds.
After cooling period, it comes with the trimming process, the correct dimensions of forges pieces are carefully verified. Then the exceeding materials generated by hammer in forging process will be removed, up to now the wrench takes its definitive shape. Then the rough wrenches are sent to another plant to eliminate the roughness. The wrench then will be checked thoroughly by experts to ensure the right dimension, and also check if the tools are in full compliance with the standards. 
After that he wrenches are put into drums along with stone water and abrasives to smoothen the surface of wrench. 
5.Machine marking 
Then with a hydraulic press the trademarks and size will be imprinted.  The multi-spindle drill will create accurate bores on the ring end, the mechanical department control if the bore size is in compliance with standard.
A shaped tool called broach is insert into the bore and pulled down generating the bi-hex profile of the tool for the purpose of correct matching to nut. Then special gorges are used to check the hex profile of wrench.
The wrenches are kept in metal basket and then put in the hardening furnace until reaching a temperature of 850 degrees centigrade, the disassociated methane at a high temperature generates a gas that can protect pieces from oxidation. The tempering phase will give metal strength and durability. Then the wrenches are dipped into an oil bath where they will coll rapidly and become hard and resistant.
The combines action of chemical additives and small ceramic stones perfectly polish all surfaces of the tool which are magnetically separated from stones.
In this phase, the wrenches will go through the  galvanic treatment with an electrolytic process a thin layer of material is deposited to add qualities to the wrench that are lacking in steel, nickel and chrome to improve aesthetics and render the tool resistant to corrosion.
