introduction： hardness Hardness or needle penetration，It is a measurable characteristic that must be considered in the selection of appropriate greases。The hardness of grease is determined by number，0The softest size，Then follow1No.，2The number is increased6stop-date。6The hardness of the number is the same as that of the soap bar。Mud in the garden is soft and easy to shovel in，Harder to shovel in，The hardness of grease is the same，It is graded according to the penetration depth of the grease falling from a certain height by the cone meter。The printing machine is a grease that must be added with appropriate hardness according to the requirements of the printing machine manufacturer，Otherwise, it may cause insufficient lubrication or increased resistance to the parts。

introduction：one、What is a hot runner Hot runner technology is an advanced technology applied to the casting runner system of plastic injection mold，It is a hot direction in the development of plastic injection molding process。The so-called hot runner molding means that the plastic sent from the injector nozzle to the gate is always in a molten state，It does not need to be cured and removed as waste at each mold opening，The molten material retained in the pouring system can be injected into the cavity during a second injection。 The ideal injection molding system should form parts of uniform density，Not subject to all flow channels、Effect of flash and sprue。Relative to cold runner，Hot runner to do this，
