Nitriding is a heat-treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface. A Nitrided Screw has a plethora of manufacturing capabilities. The applications of nitrided screws are injection molding, extrusion molding, and blow molding.

A tie bar or in other words known as a tie rod is a structural unit used as a tie. Tie bars are capable of carrying only tensile loads. In general, because the ratio of the typical tie bar's length to its cross-section is usually very large, it simply buckles under the action of compressive forces. The working strength of a tie rod is the product of the allowable working stress and the bar's minimum cross-sectional area.

Injection heads are mostly used in the manufacturing process of plastic injection molding. The shut-off nozzle injection heads serve as the connection between the plasticizing barrel and the mold itself. The main purpose behind using shut-off nozzle injection heads is to avoid drooling of the melt and stringing. Plus, they are also used to feed with a retracted nozzle. Shut-off nozzles are mounted on the machine side of the plastic molding injection process instead of being mounted on the mold side of the plastic injection process.
