India’s Leading Bimetallic Barrel Manufacturers You Should Know in 2025

 The efficiency, lifespan, and quality of output in plastic processing depend heavily on the heart of the machinery: the screw and barrel. As the industry increasingly handles abrasive, corrosive, and high-performance polymers, the demand for superior components has propelled India's Bimetallic Barrel Manufacturer segment into a space of advanced engineering and precision.

Bimetallic barrels, which feature a wear and corrosion-resistant alloy lining centrifugally cast inside a robust steel base, are crucial for achieving long-term operational stability. Understanding who the key players are ensures that manufacturers partner with the best for reliable, high-output production.

The Dominance of Gujarat and Tier-1 Cities

India’s screw and barrel manufacturing sector is heavily concentrated in industrial hubs, with Ahmedabad, Gujarat, emerging as a major center for specialized components. Several prominent companies based here and in other major industrial cities have built strong reputations for quality and customization.

These manufacturers have invested heavily in sophisticated technology, including advanced CNC machining centers and centrifugal casting equipment, to meet stringent international quality standards. They cater not only to the domestic market but also serve as significant exporters, making them globally competitive.

Bimetallic Barrel Manufacturer: The Wear and Tear Specialists

When processing tough materials like PVC, LCP, or polymers heavily filled with glass fiber or talc, a standard Nitrided Barrel Manufacturer may not offer a durable enough solution. This is where Bimetallic Barrel Manufacturer expertise is indispensable.

Leading Indian firms are recognized for their specialization in high-performance barrels with nickel, cobalt, or iron-based alloy linings (like Stellite or Colmonoy). Companies such as Vishwakarma Plast, B.R. Engineering Works, Khodiyar Engineering, and Shreeji Corporation (among others, often cited in market reports) have established strong market presence. They offer:

  • Extended Lifespan: The alloy lining dramatically increases resistance to abrasion and corrosion compared to traditional steel barrels.

  • Consistency: Superior internal surface quality ensures smoother melt flow and reduced friction, which translates to consistent product quality.

  • Customization: They provide barrels with diameters ranging from small-scale laboratory units (20mm) up to large industrial extruders (200mm and above).

Beyond Standard: The Role of the Special Barrel Manufacturer

The modern plastics industry demands more than just standard parts. A Special Barrel Manufacturer is one that provides components tailored to unique processing challenges, often combining different surface treatments to optimize performance for specific polymer chemistries or applications.

  • Nitrided Barrels for General Purpose: Many top manufacturers, including those who specialize in bimetallic parts, also remain key players as a Nitrided Barrel Manufacturer. Nitriding remains the preferred, cost-effective solution for non-corrosive, lower-abrasion commodity polymers like PE, PP, and PS. Companies like Shreeji Corporation offer an extensive range of these products.

  • The Customization Edge: A Special Barrel Manufacturer offers advanced hybrid solutions. This can include specialized features like vent barrels for devolatilization, grooved feed sections for high-output extrusion, or barrels paired with customized screw geometry (e.g., barrier screws, mixing elements) to handle complex compounds, ensuring optimal melting and mixing efficiency.

In 2025, any plastic processor aiming for efficiency, minimal downtime, and the ability to process cutting-edge materials must carefully evaluate the specialized offerings from India’s top barrel manufacturers, prioritizing those with proven expertise in advanced Bimetallic Barrel and custom Special Barrel technology.

Hardened Screw Manufacturer and Exporter | Shreeji Corporation

  Hardened Screw The hardening of screws is done by two processes — quenching and annealing. Quench hardening i s  the first process in which steel and cast iron alloys are hardened. The material — here the screw, is heated to a certain temperature and then rapidly cooled. This makes the screw hardened. The hardened screw is then tempered to reduce the brittleness that may have been increased from the quenching process. Another process is the annealing process. This is a kind of treatment in which heat alters the micro-structure of the screw which eventually causes changes in properties like strength, hardness, and ductility of the screw.  Hardened screws  use imported high-speed steel, after a series of quenching & annealing processes to achieve high toughness & hardness, especially suitable for high wearing production. The material that is used in H13 to achieve the surface hardness between 62–65 HRC. The available diameter sizes vary from 14mm to 120mm and...
