Screw Elements
Premium Screw Elements for Co-Rotating Twin Screw Extruders
As a leading screw elements manufacturer, exporter, and supplier, Unity Engineering Works specializes in high-performance, precision-engineered components. We provide durable, wear-resistant Single and twin screw elements designed to optimize your compounding and extrusion processes.
Screw elements are individual modular screw components For Twin Extruder Machine in precision-driven industries such as plastics, food, pharmaceuticals, and chemicals. They are formed by the assembly of intermeshing, counter-rotating single or twin screws that rotate inside a segment barrel, ensuring proper conveying, melting, shaping, and uniform dispersion of materials.
The elements are designed to perform various functions that include conveying, melting and shape forming of materials inside the extruder. Use of these Twin Screw elements is vital for better material flow and gives a consistent output and high-quality end products in broad-spectrum industries like food, plastics and pharmaceuticals.
Special Features
- Increased Mixing capacity : Provides good blending and mixing of materials.
- Controlled Material Flow : Gives Accurate control over material processing.
- High Quality Output : Offers a consistent and uniform end-product quality.
- Versatile Design : Application for all king of material processing.
- Efficient Compounding : Guarantees excellent compounding with minimum flows.
- Durable Material : Quality manufactured from value materials long lastingly durable.
How Our Screw Elements Improve Process Efficiency
- Optimized Mixing & Homogenization : Our mixing and kneading elements enhance dispersion and blending, ensuring uniform color, additives, and fillers.
- Controlled Residence Time : By using reverse flight or transition elements, you can regulate residence time to avoid degradation of heat-sensitive materials.
- Pressure Management : Barrier and tapered screw elements help maintain optimal pressure for efficient melting and degassing.
- Durable & Modular : Made from wear-resistant alloys, our elements are modular and customizable, supporting long-term reliability and flexible screw configurations.
Explore Types of Screw Elements We Provide
We provide a complete range of precision-engineered screw elements—including conveying, mixing, kneading, and transition profiles—manufactured under stringent quality control. Each component is designed for global export, supplying major extruder brands with reliability and performance.
SINGLE-LOBE CONVEYING ELEMENTS
Single lobe conveying elements. because of the wide tip, exhibit a better forced feeding behavior com- pared to two-lobed elements. These elements build up pressure with less energy input & often exercise a sealing function toward the gearbox at the beginning of the screw.
SE YY CONVEYING ELEMENTS
Conveying element with single-lobe design where YY represents the tip width preferably reduced to the width of the bilobed screws. Is usually employed for relative large pitches in zones where much free conveying volume is required, that is, in the intake area or the area of side feeders and degassing openings.
SE12 TRANSITION ELEMENTS
These transaction pieces create a continuous transaction between single-lobe elements of the type SEA YY to two- lobed sealing problem elements without dead spots in which product may become deposited. The Transition Element SE12 is typically used in twin-screw extruders to facilitate the smooth changeover .
SKK CONVEYING ELEMENTS
Two-lobed conveying element with two-sided pushing height at relatively large. pitch. This creates a large free conveying volume at simultaneously quite favourable blank angles. These elements can also pull in large volume particles with low density. The Conveying Element SKK is designed for efficient material transport.
BI-LOBED PUSHING FLIGHT ELELMENTS
Conveying elements in bi-lobed design of the type SK with relatively large pitch where the active, that is the pushing hight features a pushing adge. These elements exhibit a relatively large free volume where the passive hights are cleaned by the nei- bouring elements. The fitting transation pieces have the designation SKN.
