Puide Pillar is one of the indispensable key components in mold manufacturing, mainly used to ensure that the upper mold and the lower mold in the molding process of accurate guidance and positioning, so as to ensure the consistency and stability of the mold in the stamping, injection molding, die casting and other processes.

What are the functions and roles of Puide Pillar?

Precise guiding: Ensure the precise alignment of the upper and lower molds during the mold closing process, avoiding mold misalignment and improving the precision of the products.

Stable support: Provide stable support when the mold is closed, reduce the deformation of the mold under high pressure, and extend the life of the mold.

Safety buffer: During the process of mold opening and closing, the cooperation between the guide pillar and the guide sleeve plays a buffer role to reduce the impact and protect the mold.

Ejector Guide Pin can be divided into what structure?

Cylindrical guide pillar: The most common type, simple structure, high guiding accuracy, applicable to a variety of molds.

Shoulder guide column: One end of the column has shoulder design, easy to install and fix, commonly used in molds that need positioning.

Stepped guide pillar: With different diameters of the ladder structure, suitable for molds that require special guidance or support.

Hollow Guide Column: Hollow in the center, can be used for cooling water or gas channel in the mold.

What materials are generally chosen for mold guide pillars?

Commonly used materials include carbon steel, alloy steel, stainless steel, etc., which are selected according to different usage requirements and environments.

Heat treatment: Heat treatment such as quenching and tempering is usually carried out to improve hardness and wear resistance and ensure long-term stable working performance.

Surface treatment: Chrome plating, nitriding, PVD and other surface treatment can further improve the wear resistance and corrosion resistance of the guide column.
