Precision-cast Body & Cover of Meat Grinders

The Precision Cast Body Cover of Meat Grinders is a hygienic, high-integrity component designed for safe and efficient operation in food processing equipment. Manufactured from food-grade stainless steels such as 304 (UNS S30400) or 316L (UNS S31603) via precision casting, these covers undergo electropolishing and passivation to achieve a smooth surface (Ra ≤ 0.8μm) that minimizes bacterial growth and product residue retention.

Engineered to withstand repetitive mechanical stress and aggressive cleaning agents, the covers feature tight tolerance fits (ISO 2768-mK) and crevice-free geometries, ensuring compliance with USDA, 3A Sanitary Standards, and EU 10/2011 food contact regulations.

This casting part is the assembly of body and cover for meat grinders. It offers significant advantages in high precision and complex structures, excellent mechanical properties, and superior polished surface finish.

Hygienic Design Compliance: Electropolished surfaces eliminate micro-roughness, while radiused internal corners (R ≥ 3mm) and seamless transitions prevent material buildup, facilitating quick cleaning with CIP (Clean-in-Place) systems.

Corrosion Resistance: 316L alloy provides superior resistance to organic acids (e.g., lactic acid in meat) and chloride-based sanitizers, outperforming 304 in wet grinding environments with high salt content.

Structural Rigidity: Reinforced ribbing and stress-relieved casting withstand clamping forces up to 500 Nm, ensuring no deformation during high-load grinding operations (up to 2,000 RPM).

Interchangeable Design: Standardized mounting flanges and quick-release latches allow compatibility with leading meat grinder brands, reducing downtime during maintenance or product changeovers.

This casting part plays a vital role in providing structural support, protecting internal components, reducing vibration and noise, extending service life, improving production efficiency.

The assembly parts of body and cover are applied in various fields, including home kitchens, the catering industry, food processing, scientific research and laboratories, meat retail stores, pet food processing, farmers’ markets and meat wholesale markets.

Meat Processing Plants: Used in industrial grinders for hamburger patties, sausage stuffing, and pet food production, where frequent contact with salt, moisture, and acidic marinades demands corrosion-resistant hygiene.

Dairy & Poultry: Installed in mixers and emulsifiers for processing cheese, poultry mince, and seafood paste, ensuring compliance with allergen-free and halal/kosher certification requirements.

Confectionery & Bakery: Forms the protective housing for nut grinders and dough mixers, with electropolished surfaces preventing sugar crystal adhesion and enabling rapid sanitization between batches.

Food Packaging: Integral to grinding systems for producing textured vegetable protein (TVP) and food additives, where 316L covers resist degradation from alkaline processing solutions.

Q: What cleaning agents are safe for these covers?

A: They are compatible with alkaline (pH 12-14) and acidic (pH 2-4) cleaners, including peracetic acid and sodium hydroxide, with recommended temperatures ≤ 80°C (176°F).

Q: Can the covers be customized for legacy grinder models?

A: Yes—reverse-engineering services use 3D scanning to replicate exact dimensions, including bolt patterns, gasket grooves, and handle placements for seamless retrofitting.

Q: Does the electropolish finish affect the cover’s impact resistance?

A: No—the process removes only 5-10μm of material, preserving the base metal’s toughness (≥ 200 J/cm² Charpy impact value for 316L) while enhancing corrosion resistance.
