Guide rod, Guide pin in English--〖Mechanical mold〗 --[Mold terminology] The material of the guide rod is generally selected from bearing steel,
 hot working die steel, easy-to-turn iron, etc., and the use of bearing steel SUJ2 is relatively large, which greatly enhances the durability and replaceability of the guide rod in guiding performance.
 The guide rod and the assembly form the outer guide rod assembly and the inner guide rod assembly, which have a beautiful metallic luster.

Mold accessories, used in conjunction with the guide rod, play a guiding role, generally with a very small clearance,
within 0.05mm; generally used in molds or some machinery to ensure the accuracy of movement.
