Nitrided & Bimetallic Barrels

Barrels

Nitriding & Bimetallic to meet different request on wear-resistance & long life span. Advanced screw design reduces shear force,making plasticizing process more gentle,more stable and more even.

The plasticizing cylinder is an extremely important component in the plasticizing process because it must give robustness to all other members of the group, ensuring resistance to high pressures and wear and tear.

We aim to meet the challenges of an ever-changing industry and to constantly provide plasticiizing units of the highest quality, using the best steels (available on the market).

Selecting the right design

Selecting the right design for your process is critically important to optimizing melt conditions and maximizing your material properties. Plastic materials have broad variations in viscosity, melting points, volatiles, densities, moisture, sensitivity to shear, abrasive contaminants, etc. All of these variables, alone or in combination present significant barriers to maintaining homogeneity and melt consistency and 1output.
We can help you choose the optimal design for your process. From single-stage general purpose to two-stage barrier designs to double vented and with a host of mixer technologies and wear-resistant alloys, we have what you need to maximize your process. We have everything from low work to high work designs that work to keep your resins in proper condition.

Barrels

In the Manufacture of Barrels, we offer several Bimetallic Inlays for types of applications that require:

  • Wear Resistance
  • Corrosion Resistance
  • Extreme Wear & Corrosion Resistance.

For your current Barrel, Resleeving and Honing are offered for cost-effective ways to improve productivity. Inspections need to be performed to determine if these are options that will improve your current application.We offer high performance barrel construction options for corrosion and abrasion wear process environments. Upon application review, our technical sales staff carefully selects the optimum barrel bore compatible with the feed screw, resin, and application process.

A bimetallic cylinder commonly referred to as a barrel consists of two different metals bonded together. The ID liner is a metallic alloy designed to form a hard abrasion and corrosion wear resistant liner. The liner is uniform down the length of the cylinder bore. It is precision honed to a close tolerance fit between the feed screw outer flight land diameter and the barrel ID. The outer backing steel material is constructed from high strength steel alloys. Liners are bound into the ID through centrifugal casting, sintering and interference fit methods. When required Injection barrels are fitted with high-pressure sleeves at the discharge end.
