Stainless Steel Injection Molding Machine Screw And Barrel AISI304/316

Stainless steel injection screw barrel AISI304

Product Summary

Our stainless steel injection molding screw and barrel is manufactured from AISI304 or AISI316 to meet stringent hygiene and corrosion resistance requirements. With a surface roughness of Ra 0.4 and optional electropolishing, it is ideal for food, pharmaceutical, and medical device injection molding.

Key Selling Points

  • Corrosion Resistance: AISI316 offers enhanced resistance to chlorides and acids, ideal for medical and food environments.
  • Hygienic Surface: Surface roughness Ra 0.4 minimizes bacterial adhesion and facilitates cleaning.
  • Non-Contaminating: No rust or flaking, ensuring product purity for sensitive applications.
  • Full Traceability: Material certificates available for each batch.
  • Customizable: Available with or without nitriding; electropolishing option for mirror finish.

Models and Options

Available as solid stainless steel or with stainless steel cladding over carbon steel base for cost optimization.

Materials and Structure

Fully stainless steel construction using AISI304 (general) or AISI316 (marine/medical). Can be combined with other grades like 17PH-4 for higher strength.

Applications

Best suited for injection molding of food packaging, medical syringes, bottle caps, and other products requiring non-toxic, non-corrosive processing.

Customization

We offer custom lengths, compression ratios, and surface finishes. Clean-room packaging available on request. MOQ: 1 unit.

FAQ

Is AISI304 suitable for food contact?

Yes, AISI304 is FDA compliant for food contact. AISI316 is preferred for more corrosive environments.

Can you provide material test certificates?

Yes, we provide mill certificates with every order.

What is the maximum diameter you can produce in stainless steel?

We can produce up to Φ300 in stainless steel.

Do you offer electropolishing?

Yes, electropolishing is available as an option to achieve surface roughness as low as Ra 0.2.

How do stainless steel screws compare to nitrided ones in wear resistance?

Standard stainless steel is softer than nitrided steel, but for applications where corrosion resistance is critical, it is the preferred choice. We can also nitride stainless steel for improved wear.
