A bimetallic screw is made up of two metals or alloys. As the name suggests, in a bimetallic screw, two metals are fixed together. A bimetallic screw is used to increase the life of the entire screw and barrel. That is because a bimetallic screw works better than a mono-metallic screw. Bimetallic screws are made in two metals - the base material and the coating material. That is why a bimetallic screw lasts longer than a mono-metallic screw. There are multiple applications of a bimetallic screw. 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. STELLITE PTA welding 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 screws to abrasion, high temperature & corrosion. It helps extend the service life of the bimetallic screw. <br/> The material that is used in a Bimetallic Screw is EN41B with a coating of ni-based alloy. The available diameter sizes vary from 14mm to 200mm and the available length is upto 6 meters. The surface hardness achieved through the Gas Nitriding + PTA process is 58-62 HRC.
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 tie bar. Our tie bars provide good straightness and modify old straightness. It never bends and creates low noise during production. The diameter ranges from 30mm to 400mm and the length is usually less than 10,000mm.
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 at Shreeji Corporation are made from EN41B material that provides hardness of 65-68HRC and the available diameter sizes are from 14mm to 200mm.
The Ring Plunger set is also known as Torpedo or Nose cone Set and it is mostly applicable for injection molding machines. Our RP Sets have high tensile strength and we are known for their precise construction. We use different materials for the production of our RP Sets. The materials used for RP Sets are EN41B, H13, and D2. To make the RP Sets toughened and hardened, we use the gas nitriding process. The diameters available are 14mm to 200mm and the surface hardness that our RP Sets provide is between 62 to 65 HRC. We provide different sizes of RP Sets at Shreeji Corporation and we also offer RP Sets of customized needs. RP Sets are used in injection molding machines and blow molding machines. Shreeji Corporation is known for manufacturing different types of RP Sets. The types of RP Sets that we manufacture are Rotating RP Sets, Non-Rotating RP Sets, Ball Type RP Sets, Pin Type RP Sets.
Nitrided Screws and Nitrided Barrels offer a wide range of manufacturing capabilities. Their applications include injection molding, extrusion molding, and blow molding.
Parallel twin screw barrels are extensively used in extrusion machines for producing profiles, tubes, sheets, foam, and plastic compounds. They efficiently process various polymers and can achieve high output, reaching several tons per hour depending on the size.
Bimetallic screw barrels are composed of two metals or metal alloys and are typically coated with an additional layer of carbides or other commercial coating materials for enhanced durability.
An Extruder Screw Barrel is a critical component in plastic and rubber extrusion machines. It consists of a screw (also known as an auger) that rotates inside a barrel, facilitating the melting, mixing, and pushing of raw polymer material through a die to form a continuous shape.
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.
Injection heads are primarily used in the plastic injection molding manufacturing process. Shut-off nozzle injection heads act as the link between the plasticizing barrel and the mold.
