Food-Grade Stainless Steel Parts

We specialize in CNC precision machining of food-grade stainless steel components, focusing on hygiene safety, corrosion resistance, easy cleaning, and consistent accuracy. Our parts are widely used in food processing equipment, kitchenware, pharmaceutical filling systems, and dairy processing machinery.

With factory-direct supply, we support global low-volume, multi-variety customization of 440C stainless steel turned parts. By combining food-grade process standards with specialized surface treatments, our components fully meet the strict hygiene and performance requirements of the food and pharmaceutical industries. We can provide FDA certification and test reports upon request.

Our factory operates nearly 50 CNC lathes and 30 secondary processing machines, including both fully automatic and semi-automatic equipment, enabling us to handle orders of all volumes for precision components.

Customization Service

We offer fast-response customization based on your drawings:

• Drive shafts, positioning pins, sleeves, locking parts

• Filling nozzles, mixing components, conveying parts

• Custom complex geometries, precision holes, and hygienic no-dead-angle designs

Our engineers provide one-to-one drawing evaluation with quotations within 12 hours. Flexible production cycles and direct factory supply ensure efficient delivery for food and pharmaceutical applications.

Food-Grade Standards & Process Advantages

We use premium 304/316 food-grade stainless steel as base materials, combined with passivation cleaning processes that meet food safety standards.

Key Benefits

Materials comply with GB 4806.9-2016, FDA, and other food-grade standards, ensuring no harmful substance release when in contact with food or pharmaceutical media.
Hygienic machining with no dead corners: smooth surfaces and internal cavities free from burrs, grooves, or sharp edges, preventing bacterial growth.
Food-grade surface treatments form dense protective layers, improving corrosion and wear resistance without harmful coatings.
Excellent machinability allows complex structures for conveying, mixing, and transmission applications.
Strong corrosion resistance against food acids, alkalis, water exposure, and high-temperature cleaning conditions.
Long-term stability with no rust or oxidation.

To eliminate risks of metal burrs during food contact, every part undergoes surface polishing and ultrasonic cleaning. For complex internal features such as stepped holes or slots, we apply 20–50× magnification full inspection to ensure safety.

These components are commonly used in products such as coffee machines, meat grinders, mixers, and baby feeding devices.

Our capabilities also extend to high-performance 440C stainless steel turned parts, suitable for specialized food-grade applications requiring enhanced hardness and wear resistance.
