Helical Gear Powder Metallurgy Tool Design & Die Compaction

Our company specializes in the design and manufacturing of helical gear powder metallurgy tooling, providing customized processing services to solve complex tooth profile forming problems for customers. In precision machinery, power tools, and automotive transmission systems, helical gears occupy an important position due to their smoother tooth surface engagement, lower noise, and higher load-bearing capacity. The powder metallurgy process enables helical gears to achieve complex tooth profiles, batch product consistency, and high material utilization, making them highly suitable for large-scale production scenarios.

Helical gear powder metallurgy tooling is specifically designed for manufacturing high-precision, low-noise helical gears. Through the powder metallurgy process, helical gears with complex structures can be formed in one step, such as products with internal splines and stepped features, significantly reducing production costs while ensuring dimensional consistency, covering full specifications from module 0.3 to 5.0 millimeters.

Low-price custom solutions. Our factory business includes designing, developing, and manufacturing powder metallurgy moulds, carbide parts, powder injection moulds, stamping toolings and precision mould parts.

Helical Gear Powder Metallurgy Tool Design and Machining

The molds adopt a multi-punch combination structure to address complex tooth profiles and unequal height features. For stepped helical gears, “one upper and two lower” or “three upper and three lower” punch configurations are employed, combined with floating die technology to achieve bidirectional pressing, ensuring uniform tooth density. Core components include helical female dies and spiral guide mechanisms. The female die cavity is processed using variable module design methods for high tooth profile accuracy; the spiral guide mechanism ensures the upper punch rotates into the female die along the helical angle during pressing, avoiding die collision issues. Our company has professional processing engineers and modern machinery to ensure processing accuracy of tooth surface angles, helix angles, and tooth direction transitions.

Helical Gear Powder Compaction Tooling Material Selection

Key mold components utilize WC-Co tungsten carbide and ASP-60 powder high-speed steel, strengthened through vacuum sintering and deep cryogenic treatment, achieving hardness above HV2800. Cavities are processed through five-axis linkage machining technology, with tooth direction tolerances controllable within 0.01 millimeters, and clearance gaps precise to 0.005 to 0.015 millimeters, effectively avoiding tooth surface scratching and misalignment issues during forming.

We provide comprehensive customized processing services, from needs analysis through mold design, material selection, production machining, and final debugging, ensuring molds perfectly match customer production requirements. With remote technical support, we help enterprises reduce production costs and enhance market competitiveness.
