Thermal expansion metal material mainly refers to its linear expansion coefficient. Thermal expansion can cause deformation of the workpiece, and altering the shape cracking read. Thus affecting the accuracy and service life of parts or the entire device. High-precision machine tools and instruments, usually placed in a heated house processing and measurement products. Is to consider this factor. In the design of hollow glass processing equipment parts, often to consider conducting phase permeability of metallic materials: such as copper, aluminum wire require good conductivity, resistance wire resistance requires large hollow glass production lines Which is good, transformers and motor core requires good permeability. Also affect the thermal conductivity of metal material heating and cooling rate. Such as poor thermal conductivity of high-speed steel, and in forging should be heated slowly, or prone to cracking. Insulating glass production line is a combination of the various components connected through different ways. Common mechanical connection has two categories: one is the mechanical work, you can have the amount of change in the relative position of the insulating glass production line is connected between the supply of spare parts manufacturers, this connection is often referred to as mechanical work connected insulating glass production line price such as various sports deputy; the other is the mechanical work in insulating glass production line, the relative position between the connected components is fixed, do not allow relative movement, this connection is often called static mechanical connection. Supply of insulating glass production line manufacturer, Dickson machinery, insulating glass production line provided by Shandong Machinery Co. Dickson. Machinery Co., Ltd.
