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. At Tirupati Industries, we manufacture with the great precision, a wide variety of screw designs:

Single Screw

Bimetallic Screw

Tirupati Industries has 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:

1. TC Coated Melt Zone:

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

Features:

  • Higher life than just nitride screw
  • Less wear
  • Longer life
  • Sustain filler damage
  • Economical

2. Full Encapsulated TC Coating:

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
  • Longer life
  • High Wear and corrosion resistance
  • Unified coating thickness (0.08 to 0.10)
  • Mirror finish
