2026-06-09
Our company has successfully completed the trial production and mass production launch of the bolt hot forging process utilizing horizontal hydraulic presses, delivering premium-quality bolt products with outstanding forming performance, dimensional accuracy and surface finish. This milestone marks a significant upgrade in the company’s fastener hot forging technology and equipment application capabilities.
Compared with traditional vertical pressing machines, horizontal hydraulic presses adopt a horizontal forging method that delivers precise feeding alignment and uniform workpiece stress distribution. This process is particularly ideal for manufacturing long shank bolts and bolts requiring high concentricity. Featuring a high degree of automation, the equipment autonomously executes the full production workflow including precision feeding, horizontal extrusion forming and workpiece ejection. With controllable pressing speed and striking force, the entire production process maintains exceptional stability and high efficiency.
Mass production verification has proven that bolts manufactured via this upgraded hot forging process possess prominent competitive advantages. The bolt heads feature full forming, sharp and clear edges without burrs, missing corners or other forming defects. The symmetrical stress distribution on the bolt shank ensures excellent straightness. Supported by the hydraulic system’s precise pressure and stroke control, the finished products achieve superior dimensional consistency with minimal batch-to-batch deviation. Combined with professional descaling treatment, the final bolts deliver a smooth, flawless surface and dense metal flow lines, completely eliminating the issue of oxide scale indentation.
On-site sampling inspection data verifies that the deviation of the bolt head across-flats dimension is controlled within 0.1mm, and the shank straightness error is less than 0.5mm per meter. 100% of sampled products pass quality inspection, with finished product stability and yield rate reaching top-tier industry standards. Frontline technical operators have optimized core process parameters through repeated testing, including heating temperature, striking speed and die clearance, which fully guarantees consistent forming quality and greatly improves product inspection pass rates.
Client representatives who visited our production site conducted on-site product verification and highly recognized the premium product performance, including well-formed bolt heads, straight shanks and smooth surface finishes. Customers affirmed that the high-quality forged blanks effectively reduce the difficulty of subsequent thread machining processes, improving overall processing efficiency and finished thread quality.
According to our company’s technical director, this breakthrough in forging technology stems from optimized equipment selection, iteratively refined process parameters and high-precision die design and manufacturing. The technical team will further promote this mature, high-stability process to the production of more bolt specifications to sustain long-term premium product output.
This process upgrade fully validates the reliability and superiority of the horizontal hydraulic press hot forging process, further consolidating the company’s core quality advantages in fastener manufacturing. It provides solid technical and product support for expanding high-end customer markets and undertaking high-spec customized orders. Moving forward, our company will continue to focus on process optimization and technological innovation, leveraging advanced forging equipment and sophisticated craftsmanship to supply high-quality, high-precision fastener products for global customers.
