High-precision CNC turning & milling for food-grade machinery parts. Specialized in 316L, Delrin, PEEK & FDA-compliant materials. Get a fast quote today!
Food processing and packaging equipment requires components engineered to the highest hygiene and durability standards. Parts must endure aggressive chemical washdowns, extreme temperature fluctuations, and high-cycle mechanical stress without compromising safety. We specialize in custom CNC machining of non-standard precision parts tailored to meet the strict demands of the food machinery sector.
1. Comprehensive Material Capabilities
We process a wide range of food-grade compliant metals and engineering plastics:
-
Stainless Steel (Food Grade Compliance):
-
AISI 304 / 304L: Standard choice for structural frames, housings, and non-corrosive contact zones.
-
AISI 316 / 316L: Superior pitting and chemical resistance, designed for high-salinity environments, acidic foods, and harsh CIP (Clean-in-Place) chemicals.
-
420 / 440C: High-hardness martensitic stainless steel, ideal for wear-resistant cutting blades and drive shafts.
-
-
Engineering Plastics (FDA-Compliant Options):
-
POM (Acetron / Delrin): High tensile strength and low moisture absorption, widely used for gears, sprockets, and wear strips.
-
PEEK: Exceptional thermal and chemical resistance for high-temperature steam washdowns and heavy-load bushings.
-
PTFE (Teflon) & UHMW-PE: Ultra-low coefficient of friction and non-stick properties, preferred for guides, scrapers, and sanitary seals.
-
-
Aluminum & Copper Alloys:
-
6061-T6 / 7075 Aluminum: Lightweight structural components (typically with hard-coat anodizing).
-
Lead-Free Brass & Bronze: Customized drive bushings and specialized non-sparking components.

2. Precision Machining & Manufacturing Processes
Our facility handles complex geometries, tight tolerances, and fine surface finishes:
| Manufacturing Process | Capabilities & Technical Advantages | Typical Food Machinery Applications |
| CNC Milling (3/4/5-Axis) | Complex contoured surfaces with tolerances up to $\pm0.005\text{ mm}$. | Pump housings, valve manifolds, dosing molds, guide tracks |
| CNC Turning / Turn-Mill | Single-setup multi-process turning and cross-milling for high concentricity. | Drive shafts, mixing agitators, custom fittings, nozzle cores |
| Wire EDM & Sinker EDM | Precision cutting of hardened alloys, deep slots, and irregular internal features. | Cutting blades, extrusion dies, perforated filter plates |
| Precision Grinding | High-flatness surface finishing for leak-tight dynamic sealing applications. | Mechanical seal faces, precision metering cylinders, utility blades |
3. Specialized Surface Treatments for Sanitary Design
To prevent bacterial buildup and ensure easy cleaning in compliance with sanitary design standards:
-
Electropolishing: Reduces surface roughness down to Ra 0.4, removes micro-burrs, and vastly improves corrosion resistance.
-
Passivation: Enriches the chromium oxide layer on stainless steel parts to prevent rusting under acidic washdowns.
-
Hard Anodizing & Teflon Coating: Enhances surface hardness, abrasion resistance, and non-stick performance on aluminum components.
4. Quality Assurance & Custom Manufacturing
-
Strict Print Adherence: Full customization for prototype development through high-volume production.
-
Traceable Inspection: Quality control utilizing CMM, optical comparators, and surface roughness testers. Material and dimensional inspection reports provided with every batch.
-
Agile Production: Flexible scheduling to meet fast turnarounds for critical equipment repair or new OEM machinery builds.
