On December 31, 2025, we received an order from a major customer to manufacture a complete furnace of extra-large pistons: 6 pieces of model 260 and 6 pieces of model 245. Considering the high complexity of mechanical and heat treatment, as well as the difficulty of controlling the deformation of pistons of models 260/245, the technical department of Mianyang Qianchui Mechanical Equipment Co., Ltd. developed a complete set of optimized technological solutions. Thanks to the effective application of military technology, outstanding results were achieved: after heat treatment, the surface hardness of the extra-large pistons of the Model 260 was HRC 59-60, and the deformation amount was only 0.08 mm. The products were transferred to the warehouse in perfect condition, fully satisfying the customer's requirements.
