Professional Aluminum Alloy Gravity Die-casting & Precise Parts Machining

Honho Precision Industry Corporation, formerly known as WAKAJA Cooperation, It's a design and product development company, was founded in Taiwan in 1994. It was then transformed into a professional gravity casting and processing plant to effectively control the production process and stabilize the product quality.

The forming adopts gravity casting technology, which has high hardness and strong toughness. The machining uses CNC four-axis center processing machine. It has high smoothness and meticulous surface roughness. The cylinder head valve seat is manufactured in one piece to ensure strict accuracy and quality. Our top quality and precise measurements have reached the requirements of the world's leading professionals.

Techniques as our base. Professionalism first.Quality above all else. Honest management.Emphasis on employee training. Giving back to the society.

Increase the professional skills of all of our employees, Special training for management associates, Constant Improvement of product quality and productivity.
