Injection heads are mostly used in the manufacturing process of plastic injection molding. The shut-off nozzle injection heads serve as the connection between the plasticizing barrel and the mold itself. The main purpose behind using shut-off nozzle injection heads is to avoid drooling of the melt and stringing. Plus, they are also used to feed with a retracted nozzle. Shut-off nozzles are mounted on the machine side of the plastic molding injection process instead of being mounted on the mold side of the plastic injection process. Shreeji Corporation provides a wide range of Injection Heads with Shut Off Nozzle Injection heads and Standard heads. Injection Heads are widely used in the automotive industry and molding machines and that is why their demand is very high in the market. We provide injection heads with various specifications and requirements that are provided by our clients. We manufacture injection heads in different sizes and dimensions. The injection heads manufactured...

  A tie bar or in other words known as a tie rod is a structural unit used as a tie. Tie bars are capable of carrying only tensile loads. In general, because the ratio of the typical tie bar 's length to its cross-section is usually very large, it simply buckles under the action of compressive forces. The working strength of a tie rod is the product of the allowable working stress and the bar's minimum cross-sectional area. Tie bars are often used in plastic injection molding machines that have medium or large tonnage. The tie bars adjust the plate’s distance through the ring groove. Shreeji Corporation offers the finest Tie Bars with effective and timely delivery. As the leading tie-bar manufacturers and exporters in India, tie bars are also known as construction formwork coil rods, high carbon steel rods, thread coil rods. The material that is used in the manufacturing of Tie Bars is EN19/4140 alloy steel with quench hardening. There is chrome plating on the surface of the...

The Special barrel is a manually operated barrel that is often available in a Screw-Barrel configuration. It comes in a varied range of sizes and combinations and is silver in color. Since the production process is precise dimension-wise, our experts keep a close eye on it. Machines that profit from our Special Screw Barrel include blow molding machines, cable wire machines, food processing machines, and fruit mixing machines, to name a few. The length and diameter of the same can be customized to suit the needs of our customers. High-tech equipment is used to polish and finish it, resulting in improved abrasion resistance and performance. The material used in our Special barrel is EN41B and EN19 to achieve the surface hardness between 62 to 65 HRC. The process method that we use is nitriding along with special coating. The available diameter sizes of Special barrels  range from 14mm to 150mm and the length goes up to 4.5 meters. Product name – Special Barrels Material – EN41B ...

A bimetallic barrel is made up of two metals or alloys. As the name suggests, in a bimetallic barrel, two metals are fixed together. A bimetallic barrel is used to increase the life of the entire screw and barrel. That is because a bimetallic barrel works better than a mono-metallic barrel. Bimetallic barrels are made in two metals - the base material and the coating material. That is why a bimetallic barrel lasts longer than a mono-metallic barrel. There are multiple applications of a bimetallic barrel. It can be used for corrosion formula, regrinding resin, calcium powder filling, additive fireproof materials, and additive plastic materials with less than 15% glass fiber. Special machines are adopted for hard-facing, with the alloy thickness over 1.5 mm, providing high surfacing bonding strength, dense textile & effectively improving the resistance of the barrel to abrasion, high temperature & corrosion. It helps extend the service life of the bimetallic barrel. The material ...

  Nitriding is a heat-treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface. A Nitrided Barrel has a plethora of manufacturing capabilities. The applications of nitrided Barrel are injection molding, extrusion molding, and blow molding. By using high-quality grade nitriding steel, with 72 hours of nitriding process, the nitrided layer will help the barrel to get better performance by being corrosion and abrasion-resistant. Nitrided barrels have a very good wear resistance until the surface the hardness is worn away.  The material that is used in a Nitrided Barrel is EN41B and the surface hardness achieved through that is 65-68 HRC. There are multiple sizes available at Shreeji Corporation for the Nitrided Barrel. The sizes available vary from 14mm to 200mm in diameter and the length can go up to 6 meters. Product name – Nitrided Barrel Material – EN41B Available size – Dia 14 – 200 mm, length upto 6m long Surface hardness – 62-6...
