MIM Injection Molded Meat Grinder Stirring Blade

This product is a Metal Injection Molding (MIM) meat grinder stirring blade, also known as stirring paddle or K-shaped stirring blade, a core component for stirring and mixing meat stuffing. The stirring blade typically has a complex helical paddle structure, requiring excellent dynamic balance, high stirring efficiency, and no hygiene dead corners. MIM combines the shape freedom of plastic injection molding with the material versatility of powder metallurgy, enabling one-piece forming of complex 3D paddle surfaces and center mounting structures difficult to machine, ensuring paddle symmetry, excellent dynamic balance, smooth stirring, and no meat sticking.

We use food-grade 420  precipitation-hardening stainless steel powder, through precision mixing, injection molding, catalytic debinding, vacuum sintering, quenching and tempering, precision grinding, polishing, and passivation. Density reaches 7.4-7.6 g/cm³, hardness HRC 35-55 (420 after heat treatment) , tensile strength ≥1100 MPa. Paddles are precision ground and dynamically balanced for low stirring resistance and uniform mixing. Surface roughness Ra ≤0.8μm, excellent corrosion resistance, compliant with FDA/LFGB food contact standards. All production is in clean workshops to ensure hygiene.
