16 2026-10 Guangming Group Daily Insights: What trends will powder metallurgy and MIM technology show in cutting costs for humanoid robots going forward?
English Translation (B2B industrial version, suitable for LinkedIn / company profile / overseas brochure)
Six Development Trends of Powder Metallurgy (PM) and MIM for Cost Reduction in Humanoid Robots
Core Logic: PM delivers extreme cost reduction for mass-produced standard transmission components; MIM manufactures complex integrated micro-structural parts. Instead of simply replacing CNC machining, both processes are deeply brought forward into the robot design phase to achieve synergistic cost reduction through “material-structure-process”, shifting cost optimization from component level to module level.
14 2026-10 Guangming Group’s Daily Sharing: How to Improve the Hardness and Wear Resistance of Powder Metallurgy Gears
Core principle: First increase density and reduce harmful pores (foundation), then enhance matrix/tooth surface hardness (performance improvement), and finally adopt surface strengthening and lubrication protection (reinforcement). If only heat treatment is used to raise hardness, tooth surface spalling will easily occur with insufficient density, and the improvement in wear resistance will be limited.
10 2026-10 Guangming Group Shares the Application Fields of MIM Injection Molding Technology
MIM is suitable for small-to-medium sized, complex-structured, high-volume precision metal parts (mostly 0.1～100g). It can produce thin walls, irregular holes, internal threads and micro tooth profiles, serving as an alternative to CNC machining and investment casting. Below are its major application sectors:
29 2026-09 How can high precision be achieved in MIM manufacturing?
The biggest challenge of MIM lies in the 15%~20% bulk shrinkage during sintering. High precision is essentially achieved by controlling uniformity across the entire process: stable feedstock → uniform green part density → distortion-free debinding → consistent sintering shrinkage. Combined with mold shrinkage compensation, post-finishing correction and SPC control, standard MIM can reach a dimensional tolerance of ±0.3%, while critical features can achieve ±0.02～0.05 mm.
24 2026-09 Guangming Group: Why powder metallurgy is the best process for meat grinder external locking cutter discs
Core Reasons Why Powder Metallurgy Is the Optimal Process for Meat Grinder External Locking Cutter Discs
The core requirements for external locking cutter discs (meat outlet plates): uniform hole positions, flat end faces, wear resistance, deformation resistance, food safety, and low cost for mass production. Near-net-shape powder metallurgy (PM) perfectly meets these requirements and has prominent advantages over stamping, CNC machining and die casting.
