introduction：The main content of plastic chain maintenance is：Inspection and prevention first，Check the relationship between the parts and whether there is damage during maintenance，Repair the damaged part，Try to keep the mold in good condition。 As a manufacturer can customize the width of the tow chain according to user requirements，The bending radius can be from18-500among。Plastic tow chains are generally made of nylonPA66，Because of reinforced nylon，Make it have good pressure，toughness，High elasticity and wear resistance，And certain flame retardancy，High and low temperature performance can be stabilized when using plastic drag chains，And can be used outdoors。Now the plastic tow chain is also constantly improving。Hope through the introduction of these knowledge，Can play some corresponding help for the majority of users。

introduction：In recent years，3DPrint on top of the material accumulation of technical characteristics，Gradually, more and more unusual characteristics were formed，And therefore expand a broader application space。Besides making other machines，3DThe printer can replicate itself；3DA printer can make objects much larger than itself；3DThe printer can realize the ordinary printer2DPrint function。 As everyone knows，3DThe big difference between printing and traditional manufacturing is that，Reduction manufacturing requires the removal of production materials、Cut to complete the machining，while3DPrinting is the opposite，The product is made by the gradual accumulation of materials，Thats what its called“Additive manufacturing”。On this basis，3DPrinting technology is constantly evolving，In recent years, more unusual features have gradually developed，And therefore expand a broader application space。
