Hoga Industry Co., Ltd. was established in 1976 in Da’An District, Taichung City, Taiwan. We are one of the biggest professional manufacturers specializing in the production of excellent quality engine valves, valve guides, and valve seats for over 45 years. We offer a comprehensive range of products suitable for all kinds of petrol and diesel engines such as motorcycles, passenger cars, trucks, heavy-duty equipment, and marine engines.
We proudly own precision production equipment and advanced manufacturing technology to meet customers’ strictest demands. In order to attain accurate dimensions, we focus on every detail of the production process and establish strict quality control by conforming to ISO/IATF16949. This principle is applied to cutting, forging, turning, welding, grinding, appearance checking, and 100% ultrasonic inspection up to the final packing. Each stage of the process is designed to achieve perfection and therefore enables us to bring out the highest quality products as well as to achieve punctual delivery. Our company is committed to delivering customers’ satisfaction and needs in both OEM and aftermarket.
