Powder metallurgy gears adopt the near-net-shape process. After sintering, parts are basically close to finished dimensions with little or no subsequent machining. Its advantages focus on five dimensions: cost, forming capability, lubrication, batch consistency and material design.

In short: Breaking the boundaries of size and material, digital and intelligent process, green short-cycle manufacturing, cross-process integration, and application expansion from 3C products to medical devices, humanoid robots, new energy vehicles and high-end aerospace components.

Applicable: Semi-automatic / fully automatic piston, pump and tracking liquid filling machines. Core idea: Source material control + scheduled maintenance + standardized operation + environment management + advance spare parts preparation. Fundamentally reduce faults such as inaccurate metering, dripping, bottle jamming and malfunction.

Core Judgement Logic: Comprehensive evaluation across six dimensions: part size & weight, structural complexity, production volume, tolerance requirements, material and cost. The more criteria met, the more suitable the part is for MIM.

Full process chain: Powder Preparation → Batching & Powder Mixing → Die Filling → Compression Molding (Green Compact) → Green Compact Inspection → Sintering → Sintered Part Inspection → Post‑treatment → Final Inspection & Warehousing The MIM (Metal Injection Molding) process: Powder Preparation + Feedstock Mixing → Injection Molding → Debinding → Sintering → Post‑treatment. A separate comparison will be provided later.

Applications: Mobile‑phone vibrators, counterweight blocks, radiation shielding components, electrodes, military‑industry spare parts
