1. First we form the head by cutting with bottom grooves, which will be used
to press in the body in later process.
2. For body part, we adopt cold forging process and make a flange on the top
to mate with the head.
3. Punch press the head and body together. Two parts are closely joined in
this process to ensure high tensile strength in accordance with customers¡¦
requirements.
4. This design not only satisfies customers¡¦ application need, but also can
save cost by 40%.
