Wu Hung Gear begins every project by carefully sourcing high-quality raw materials tailored to meet diverse industrial requirements. We work with a wide selection of metals and engineering plastics, including 45C, SCM440, SNCM220, SCM415 steels, aluminum alloys like A6061 and A7075, brass, bronze, POM, nylon, and other specialized materials.Our procurement process prioritizes reliability, machinability, and performance to ensure the final gear components maintain structural integrity and optimal mechanical properties. We collaborate with trusted suppliers to guarantee material traceability, certifications, and consistency. This foundational step sets the stage for precision manufacturing, ensuring each gear is built from material that meets the highest standards of strength, durability, and dimensional stability.

The next phase in our gear production involves advanced CNC machining processes to achieve tight tolerances and refined geometries. Our capabilities include precision turning, milling, bore grinding, and surface grinding. These techniques allow us to create complex shapes, prepare gear blanks, and ensure accurate alignment of internal features. CNC machining enhances repeatability and efficiency, which is especially critical for high-volume or custom parts. Wu Hung’s skilled technicians and modern equipment ensure that each machined component meets customer specifications while optimizing surface finish and dimensional accuracy—laying the groundwork for seamless gear cutting in the next step.

Once the gear blanks are machined, we proceed to gear forming through hobbing and shaping processes. For external teeth, we utilize precision gear hobbing; for internal gears, internal shaping is performed. We also offer gear shaveling for improved tooth surface condition. These methods are crucial in defining the gear's transmission characteristics and ensuring accurate tooth geometry. Wu Hung’s equipment supports a wide range of gear sizes and modules, from micro to mid-sized industrial gears. By combining advanced tooling with meticulous setup, we achieve consistent pitch accuracy, perfect alignment, and excellent surface finish— ensuring that each gear meets demanding application needs.

Heat treatment is applied to enhance gear durability, wear resistance, and mechanical strength. Depending on the application, we offer various processes such as tempering, case hardening, induction hardening, or full hardening. Additionally, surface treatments like black oxide, phosphating, plating, or anodizing are used to improve corrosion resistance and aesthetic appearance. Our in-depth understanding of metallurgical behavior ensures that each gear component receives the optimal treatment, resulting in a product capable of withstanding high loads, repetitive stress, and harsh environments. This critical stage ensures your gear maintains long-term performance in real-world use.

To further refine the gear's performance and accuracy, we utilize advanced profile improvement techniques such as gear skiving and gear grinding. Gear skiving allows us to fine-tune internal or external gear teeth with high speed and precision, ideal for complex or high-ratio gearsets. Gear grinding, on the other hand, is essential for achieving ultra-high precision, smooth operation, and minimizing gear noise. These finishing processes ensure that the final gear profile adheres to the tightest tolerances and quality standards. By investing in profile improvement, Wu Hung guarantees reduced backlash, better meshing, and enhanced gear lifespan.

Final inspection is a crucial quality control step to validate the accuracy and reliability of each gear. We conduct comprehensive evaluations including gear profile inspection, tooth flank measurement, and gear meshing tests. Advanced inspection tools and coordinate measuring machines (CMM) ensure compliance with DIN, AGMA, or customer-specified standards. We simulate real-world meshing conditions to verify smooth operation, load distribution, and noise levels. Every gear is delivered with full inspection reports, giving our clients confidence in the performance and quality of their components. With this thorough inspection process, Wu Hung delivers precision you can trust.
