introduction：Gear reducer is the use of all levels of gear transmission to achieve the purpose of reducing speed.The reducer is composed of gear pairs at all levels.For example, using small gears to drive large gears can achieve a certain goal of deceleration,Then adopt the multi-level structure,You can significantly reduce the RPM. Gear reducer is generally used for low speed and high torque transmission equipment，Knob motor.The power of an internal combustion engine or other high-speed operation is decelerated by meshing large gears on the output shaft with fewer teeth on the input shaft of the reducer，The ordinary reducer will also have several pairs of the same principle gear to achieve the ideal deceleration effect，The ratio of the number of teeth of the big and small gears，exactly

introduction：Mold quotation and settlement is the continuation and result of mold evaluation。From mold valuation to mold quotation，Just the first step，And the ultimate purpose of the mold，Is through the mold manufacturing delivery after the settlement，Form the final mold settlement price。In the process，People always hope，Mold valuation=Mold price=Mold settlement price。And in practice，These four prices are not exactly equal，Fluctuating error values are possible。These are the issues to be discussed below。When the mold is valued，Appropriate handling is required，Collate the quotation into the mold，To sign the mold processing contract as a basis。Through repeated negotiations，Final formation
