Z28300 Thread Rolling Machine for Steel Bars China Industrial Factory Suppliers
High-precision Z28-300 Thread Rolling Machine from a leading China factory. Specialized suppliers of cold-forming technology for high-pressure steel bars and tubing with CE and ISO9001 certification.
About this product
Product information from the supplier.
The Z28-300 Thread Rolling Machine is a high-precision industrial solution engineered specifically for steel bars and tubing. Utilizing advanced cold-forming technology, this automatic machine produces threads with exceptionally low internal stress, effectively eliminating the risk of stress corrosion—a critical advantage when working with stainless steel. By replacing traditional cutting methods, it ensures that the structural integrity of the tube wall remains intact, providing superior strength and reliability for high-pressure applications.
Designed for versatility and efficiency, the Z28-300 is an ideal choice for demanding environments such as fire control high-pressure water mist extinguishing systems, where pipeline work pressures can reach up to 16MPa. With its robust PLC control system and precision-engineered rollers, the machine delivers consistent, high-quality threading that is as rigid as the tube body itself, ensuring leak-proof connections and long-term durability in industrial piping systems.
