On November 5th, sijin intelligent forming machinery (003025.SZ) stated in investor relations that the company's multi-station intelligent precision warm-hot upsetting forming equipment has entered a substantial research and development stage: one prototype (SJHBF-502L) has been successfully produced (currently in the trial sample stage: using this prototype to produce samples, the sample is a high-strength external hexagonal bolt, model M42×420, with a diameter of 42mm, a length of 420mm, and a weight of about 5.5Kg), while another prototype (SJHF-804) is currently under trial production.
High-speed precision hot forming technology, similar to cold forming technology, is an efficient manufacturing process based on the principles of plastic forming. By heating the material to a certain temperature, the final shape can be quickly obtained, improving the internal structure of the metal, enhancing the material's load-bearing capacity, to achieve the net forming of some complex structural parts at one time, meeting the urgent need in the domestic market for batch production of large and complex shaped parts in high-end bearing, gear, steel ball, flange, automobile, and other industries.
In terms of proprietary technology for warm-hot upsetting forming equipment, the main technical difficulties of warm-hot upsetting forming equipment include heating and temperature control, cooling system, and oil-water separation. The company has mastered the core technologies of the heating and temperature control system and oil-water separation system of the warm-hot upsetting forming equipment, basically completed the technical breakthrough of the cooling system, and is currently further improving and enhancing it. As of now, the company holds 13 national patents related to warm-hot upsetting forming equipment (including 6 invention patents) and has proprietary technologies related to warm-hot upsetting forming equipment such as oil-water separation mechanisms and cooling water recycling. Therefore, the company has overcome the main technical difficulties in the manufacturing of warm-hot upsetting forming equipment and mastered the core technology of warm-hot upsetting forming equipment.
