When using cement pipe molds, it is important to select suitable products, use them correctly, and maintain them properly. Our company also manufactures and supplies pipe-making machinery, pipe molds, and centrifuges. Those interested can view and inquire on our website or call us directly for details. Incorrect operation during the use of mechanical molds can affect their performance and cause failure. The reasons for well pipe mold failure include the following:

1. Inadequate mold-making process for cement pipe molds, mainly manifested in poor internal quality of the punch and die forging blanks, problems with heat treatment technology and processes, resulting in incomplete quenching of the punch and die, soft spots, and uneven hardness. Sometimes micro-cracks or even full cracks occur. Grinding and polishing are inadequate, resulting in excessive surface roughness.

2. Lack of lubrication or ineffective lubrication.

3. Problems with the materials of the main working parts of the mold, including inappropriate material selection. Poor material properties, lack of wear resistance; unrefined mold steel with numerous smelting defects; imperfect forging processes for the punch and die blanks, leaving hidden heat treatment risks.

4. Problems with the mold structure design, including an unreasonable punch structure. Slender punches lack reinforcement devices, leading to poor material flow at the cement pipe machine outlet and material accumulation; excessive unloading force exacerbates the alternating load on the punch.

Users should select, operate, and maintain cement pipe molds according to their actual needs.
