Cold Forging
this process involves using raw wire and shaping the head of the screw through multiple stamping. Depending on the amount of stamping required for the head, cold forging machines can be categorized into various types, such as single-die two-blow, three-die three-blow, two-die four-blow… up to six-die six-blow. In short, the more complex the head, the more stamping stages are needed, the more dies are required, and consequently, the higher the associated costs.
Turning
The process involves using round bar or hexagonal bar raw materials, which are shaped through cutting. This method generally achieves higher precision compared to cold forging, but correspondingly, the costs are also higher. The advantages include no need for mold fees, high precision, and the ability to form complex shapes.
Grinding
Grinding is a surface finishing process aimed at enhancing the surface quality and precision of a workpiece. It involves using grinding tools and abrasives to cut and smooth the surface of the workpiece, removing irregularities and rough areas to achieve the desired smoothness and precision.。
Heat Treating
Heat treatment is a manufacturing process used to alter the physical and sometimes chemical properties of a material, typically metal. This process involves heating metals to a specific temperature and then cooling them at a controlled rate. Heat treatment can increase strength, hardness, and durability of metals, relieve stresses, and make them more workable. Common methods include annealing, quenching, and tempering, each serving a distinct purpose in material enhancement.
Threadlocker
Preventing loosening is a crucial issue for screws, nuts, and fasteners. Most anti-loosening mechanisms are designed for nuts, resulting in a variety of lock nuts. However, in some applications, the screw is not fastened with the nut, yet there is still a need for anti-loosening. Thus, many threadlockers have been invented. The choice of threadlockers depends on the customer’s specific application, such as requirements for high temperature resistance, waterproofing, single-use or reusable properties, and more.
