Screw
Screws are one of the most important hot parts of any plastic extruder/injection moulding or food processing plants. Since many decades, screws have been used for feeding purposes, but due to large amounts of research and development screw designs have changed drastically to make the extrusion process more and more efficient. We manufacture with the great precision, a wide variety of screw designs:
Single Screw
We manufacture all kinds of single screw design ranging from 20mm to 180mm in diameter and to 6000mm in length for below mentioned applications.
Warranty: We give warranty of 1 to 1.5 year in our Single Screw
Material: EN41B MUSCO procured from authorized dealer
Nittriding Hardness: 67 to 68 HRC
All screws are Nitrided for a better life. The life can be extended using bimetallic TC coated screws.
- Dimensional accuracy in tolerance of +- 0.02
- Nitriding layer depth is 0.5-0.7 mm
- Higher Output capacity
- Longer life with Gas Nitriding
- Extraordinary surface hardness with TC coating (Depth 1.5 to 2 mm)
- Accurate Linearity of screw (<0.02mm /m)
- Certificate of base and coating material is given
- 3rd party inspection report is provided
Orientation Extrusion Machinery:
- Extrusion Coating Machine (LD/HD/PP)
- Sheet Extrusion Machine (PP/LD/HD/ABS/PC/HIPS)
- Tape Plan
Blown Film Plant:
- MonoLayer Extrusion Plant (LDPE/LLDPE/HM/HDPE/PVC/PP)
- Multi-Layer Film Plant (LDPE/LLDPE/Nylon/HDPE/PP)
Pipe Plant:
- PVC Conduit Pipe
- HDPE Pipe
- PVC Cable Coating
- PVC Soft Tubing
- PVC Suction
- PVC Profile
- SPVC Braided Hose
- Windsor Standard
- Kabra Standard
- Lohia Standard
- Mamata Standard
- Rajoo Standard
In many applications where higher output and better mixing is required, following screw designs can be provided with great accuracy and quality.
Barrier Screw
- Increases Melting efficiency
- Increases plasticizing capacity
- Removes solid bed breakup
- Allows more control and stability
Mixing Ring
- Better mixing of melt polymer
- Homogenous melting
Twin Screw
We manufacture a wide range of Twin Screw diameter ranging from 52mm to 110mm with output capacity ranging from 110 to 900 kg/hr.
While manufacturing, We also take in consideration of market needs such as low filler, high filler and ISI grade.
Warranty: We provide warranty of 1 to1.5 year in our Twin Screw
Material: EN41B MUSCO procured from authorized dealer
Nittriding Hardness: 66 to 68 HRC
The melt section of any screw will acquire a high amount of wearing. Which leads to low output of the extruder. In order to solve this problem, we provide the Tungsten carbide coating in the melting zone using HVOF technology.
Features
- Higher life than just nitride screw
- Less wear
- Longer life
- Sustain filler damage
- Economical
If you want your screw life to be doubled, we have the perfect solution for you. At Tirupati industries, we have two types of fully encapsulation options
HVOF Coating:
With full encapsulation HVOF, we give you surety of the double life for your screws.
Features
- Higher life than just nitride screw
- Less wear
- Longer life
Flash Carbide Coating:
With this new technology, we give you similar advantages like the full encapsulated HVOF coating at lower price. In this the thickness of the coated layer is lower than HVOF but ensures the quality of product.
Features
- Economical then HVOF
- High Wear and corrosion resistance
- Unified coating thickness (0.08 to 0.10)
- Mirror finish
- Longer life
Vented Screw
We also manufacture vented screws used to extract volatiles from plastic material, ranging from 70mm to 120mm in diameter. The length depends on the design of the screw.
- Higher vapor escape
- Efficient design
- Better volatile escape
- Greater wear resistance
- No polymer leakage
- We provide inspection report
- RPVC
- HDPE
- PP/PE
- LDPE
- Nylon
Bimetallic Screw
We have capacity to provide the best Bimetallic screws by doing various types of TC coating on screws. This ensures the better life and higher working efficiency of the screw.
We provide bimetallic coating as per the economical need of the customer. We have divided our coating in two parts as shown below:
