Bimetallic Barrels

Barrel from Dia. 25 mm to 200 mm & Length upto 6000mm
Barrels processed with bimetallic alloy hardface coating have many virtues, such as high hardness,
stronger wear & corrosion resistance. Its general properties are three to fifteen times more compared
to the nitriding steel. They are wildly used for highly abrasive & corrosive materials like
engineering polymers and pvc compounds. The main machining methods are as follows: spot
spray, spray coating, cover coating, mould, butt welding etc. The bimetallic process used in world as
advanced technology for better life with consistent production and quality. It is the best choice for
production special screws.
Polymers can be used : Minerals, Glassfibers, Pigment, Carbon fibers

  • CPM/Specialized tool steel vacuum hardened Barrels
  • Spin cast boron composite inlay layer Barrel (1.5-2mm)
  • Spin cast (upto 35%) Tungsten composite inlay layer Barrel
  • PM Tool Sleeve and liners (CPM 9V)

Twin Screws

Screw from Dia. 25 mm to 200 mm & Length upto 6000mm
BASE MATERIAL: Screws are made from nitroalloy steel (AISI 4340 NITRALLOY 135M), stainless steel (304, 316, 416,
17-4ph), Tool steel & CPM tool steel.

Twin Screw & Barrel Applications: Higher proportion calcium powder is used in the parallel / conical screw process in these days. Based on this fact, kaivanya manufactures the best cofigured screw according to the client’s requirement. So the best plasticization status and blending quality are achieved. New configured screws, which can be applicable to process PVC sheet, plate, piece, pellet, mould, high foaming, are developed by Kaivanya Factory. Also, anticorrosion and wear resistant materials are
developed to better the life and enhance productivity.

Twin Screw & Barrel innovations:
»» New configured screws, which can be applied to process PVC pipes & profiles are developed by kaivanya
»» Anticorrosion & wear resistant material.
»» Polymer material can be sheared & compressed more softly in screw.
»» The twin-screw are more effective than other types, because of their high capacity and good thermal and mechanical stress.
»» Ease of Application - The powder mixing with chemical additives and melting with thermal and mechanical energy
in three zones (feed, compression and material zone) and because of gear pump and screw’s pressure, coverting to final product in latest plate.

PVD Coating
Physical vapor deposition (PVD) is a variety of vacuum deposition and is a general term used to describe anyof a variety of  methods to deposit thin film by the condesation of a vaporized form of the desired film material onto various work piece surfaces. The coating method involves purely physical processeds such as high temperature vacuum evaporation with subsequent condensation, or plasma sputter bombardment rather than involving a chemical reaction at the surface to be coated as in chemical vapor deposition.
