产品处理以后变形小（The product is less deformed after processing）

工件经QPQ处理处理之后几乎没有变形产生,可有效的解决常规热处理方法难以解决的硬化变形难题。目前,QPQ技术在众多得轴类零件、细长杆件上应用得非常成功,有效的解决了一直以来存在的热处理硬化和产品变形的矛盾。

After QPQ treatment, there is almost no deformation, which can effectively solve the problem of hardening deformation which is difficult to be solved by conventional heat treatment. At present, QPQ technology has been successfully applied to many shaft parts and slender members, effectively solving the contradiction between heat treatment hardening and product deformation.
