Quality Control Chart :

Step 1 : Inspection of Graphite Sheet
  • Test for Ash Analysis from single lot.
  • Test for Density-Mass Volume basis.
  • Lab Testing for Chemical Analysis.

Step 2 : Cutting the Graphite Sheet as tape as per requirement to make Graphite Ring. Ex : To manufacture 6 mm Graphite Ring it require 12 mm Graphite tape of 1 gm/cc.

Step 3 : Winding of Graphite Tape to ring making dyes & giving proper pressure and Manufacture ring of desired ID, OD & Thickness. Since we are using Graphite Tape width double the final thickness of Graphite Ring will take optimum load while molding in the dye.

Step 4 : Random check for Density of Graphite Ring ( 1 Out of 10) & Lab testing. Since mass by volume used density & if the density of Graphite Ring is 1.6gm/CC it can hold pressure in the Valves, Pumps or any machinery ceiling Part. If the Ash content is within the limit there will not be any problem in the final product. So Test Certificate is made as per our instruction in quality control lab.

Step 5 : Cleaning & Packing in a required set.

Step 6 : Final inspection for total quantity of Ring as per Purchase Order and Packing Inside a cotton Box, Thermacol and other accessories will be used as per Requirement.

Step 7 : Weight the total consignment and dispatch.
