▼Job Responsibilities
【Metal Processing Staff】
At our factory, we mainly specialize in metal spinning — a unique technique used to create a wide variety of products such as machine parts, aircraft components, and decorative items like vases.

You’ll be assigned to one of the following tasks: metal spinning, TIG welding, lathe operation, pressing, or drilling.
Most of our work involves custom-made or small-lot production, so attention to detail is key as each item requires its own specific checks.

No experience? No problem! Our experienced supervisors will provide hands-on training and support until you feel confident in your role.

Join us and be part of a team that takes pride in high-quality craftsmanship!
