This is the most widely used tip. This tip style is used primarily to provide Vestige height is equal to orifice diameter. reduced vestige height,0.4- 0.9mm high Provides best gate control for for all materials. most materials. Cone Point adds heatto center of orifice for Open flowbore provides lowpressure drop. nylon,acetal and PBT. Tramp metal can usually flow through tip. Orifice adjustment requires added Orifice is increased by simple straight reaming of diameter. machining to hold land length at0.08/0.13mm. > Same as CV-10 except gate orifice is > Same as CV-11 except gate orifice is machined...

Tip Removal > 1.Place a 36mm 6 point deep socket wrench over split wrench.Torque off tip with wrench assembly.See Figure 1.2.Tips are usually removed at room temperature.If tip does not break free,heatbushing to operating melt temperature. Insert Removal > 1.The conductive BeCu insert should only be removed if it is to be replaced by anew insert.Reinstallation of the same insert may affect the heat transfer from the steel body to the BeCu insert.2.Using an 11.1mm dia.drill,machine into the center of the insert for a depth of15mm,and then thread using a M12 tap.3.After the insert is tapped,thread...
