introduction：Cold extrusion is the plastic deformation of a metal material to obtain the desired shape、A forming process for dimensions and mechanical properties of parts，Thus the blank volume is equal to the part volume。 The determination of blank diameter is very important，It determines the degree of deformation of the extruded part，Reasonable diameter size can ensure the balance of deformation degree of two extrusions，To reduce the deformation resistance during extrusion，Avoid imported bearings[Imported bearing:Simply put, the import bearing agent refers to the sale of an imported bearing brand。The main brands of imported bearings arenskbearing，ikobearing，fagbearing，Of good quality，Of course, the price is not cheap。]Parts production

introduction：In traditional structural foam injection molding，Chemical blowing agents are usually used，Due to its low foaming pressure，The parts produced are limited in wall thickness and shape。The use of supercritical inert gases in microcellular foam injection molding is limited。Microcellular foam injection molding uses supercritical inert gas（CO2、N2）As a physical blowing agent．The process is divided into four steps： 1）Gas dissolution：The supercritical liquid of the inert gas is injected into the polymer melt through a syringe mounted on the structure，Form a homogeneous polymer/Gas system； 2）nucleation：During the filling process the gas drops from polymerization due to pressure

introduction：bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]Judgment of： Judging whether the bearing is available，The main consideration is the degree of bearing damage、Mechanical property、significance、Operating condition、Until the next inspection period。Can no longer be used if the following defects，New bearings must be replaced。Inner ring、Outer ring、Rolling element、cage
