Excellent material properties
(1) High precision and uniformity
Powder metallurgy process uses metal powder as raw material, which is formed through mold pressing and high-temperature sintering, and can achieve extremely high dimensional accuracy and surface finish. In textile machinery, key components such as rollers and gears have extremely high requirements for dimensional accuracy. Powder metallurgy accessories can control dimensional errors within a very small range, ensuring the stability and reliability of mechanical operation. Meanwhile, the internal structure of powder metallurgy materials is uniform, avoiding defects such as segregation and porosity that may occur in traditional casting processes. This enables the accessories to disperse stress more evenly when subjected to force, thereby extending their service life.
(2) Good wear resistance and self-lubrication
During the operation of textile machinery, the components frequently rub against each other, and the requirement for wear resistance is very high. Powder metallurgy materials can achieve excellent wear resistance by adjusting their composition and pore structure. For instance, solid lubricants such as graphite are added to the powder to produce accessories with self-lubricating properties. When these oil-impregnated bearings, sliders and other accessories are in operation, the lubricating oil in the pores will seep out, forming a lubricating film, reducing frictional resistance and lowering the degree of wear. This not only extends the service life of the accessories, but also reduces maintenance costs, shortens the downtime for inspection and repair, and improves the continuity and efficiency of textile production.
(3) High strength and high hardness
By rationally selecting metal powders and optimizing the sintering process, powder metallurgy accessories can possess high strength and hardness. In the transmission components of textile machinery, such as cams and chains, they need to withstand considerable loads and impact forces. Powder metallurgy parts, with their high strength and hardness, can effectively resist deformation and fracture, ensuring the stable operation of the machinery under high-speed and heavy-load working conditions.
