Plastic Guide Rail Made by UHMW Bar
Shore Hardness :62;
Guide rail is a slot or an object shaped like a ridge made by metal or plastic material ,it’s a device to support ,fix ,guide or transport some movable objects ,instruments and equipment .It’s also called as track or channel ,used in straight line transmission back and forth condition ,it has bigger load than bearing ,meanwhile it can support certain torque ,so it can realize high precision linear movement with high load .
The guide rail was usually made by steel ,during long time using ,the two contact surface always bear different friction ,so the surface must have many scratch ,along with more and more scratch ,it must affect the working of guide rail .The workers have to repair it at regular intervals ,then they tried to find better guide rail material to replace metal .After many tests ,UHMW material is deemed to be the best choice .This type of material has good adhesive power ,excellent compressive strength and wonderful wear resistance ,especially it has an inconceivable auto lubrication ability ,and it can form a protection layer between UHMW guide rail and transported goods ,so the service life of guide rail has been observably prolonged .
Ultra high molecular weight polyethylene is briefly called as UHMW PE ,it’s one of engineering plastics ,we use this material to make guide rail ,since the advent of UHMW guide rail ,it’s always the best plastic guide rail to replace steel guide rail .The basic material is UHMW bar ,our UHMW bars are cut from our UHMW sheet ,the sheet was made by compression molding technology ,it has many advantages than extruded sheet .Then the UHMW bars will be processed into guide rail by CNC router and other digital controlled machines .Finally the UHMW guide rail will be finished after many tests .
