GrafCompounder Tutorial and Literature

Program Description

GrafCompounder is a software, which enables you to create recipes for Rubber, TPE, TP and other compounds from an unorganized recipe & property database.

A multiple linear iteration method [MLI] is used by the GrafCompounder to calculate a compound recipe.

The GrafCompounder enables you to analyze your database and identify faulty compound data, because it allows you to identify each compound recipe and its ratio your calculated compound is composed off. This program feature is extremly helpful, if your confirmation experiment will result a difference with the compound properties calculated larger than the 95% confindence interval.

With a database, which has a sufficient high amount of compounds, you are able to use the GrafCompounder like a compound simulation tool.

GrafCompounder 3.211 Tutorial:

The Version 3.211 has a couple of new features in addition to the program features of version 2.004, which are explained in detail in this tutorial.

  • Calculation of the Grand Total sum of phr.
  • Density calculation.
  • Cost calculation: cost per volume and cost per mass.
  • Merger Function to bring different worksheets in one data table.
  • Fruequency distribution of either ingredients or physicals in the data base as bar charts.
With the new functions in the GrafCompounder 3.211 more information needed, like the cost and density of the ingredients and a code for each ingredients and property.
The program opens and stores data in its own file format: "____.gc" with "open file" in pull down menue. The export in a table calculation program is possible with copy & paste as usual.

GrafCompounder 2.004 Tutorial:

The Version 2.004 has features, which are explained in detail in its tutorial. The program allows to store the data in its own file format: ____.gc, but the export in a table calculation program is possible as well via copy & paste.
Two new columns are added in the working screen of the program:

  • The first column shows the minimum values of each row, whether it is an ingredient or property,
  • the second column shows the maximum value in each row.
This information prevents the use of calculation criteria, which are not supported by the database.
The figure below shows a screen shot of the Grafcompounder 2.004 with a recipe dataset in the left screen, the "criteria" window with the maximum and minimum columns and in the "output" window and a sample recipe calculation according to the performance criteria shown.

Minimum hardware and software requirements

The GrafCompounder software runs on Windows® XP or Windows® Vista with at least 512 MB RAM.

With Windows® 7 / Windows® 8 / Windows® 10 at least 1 GB RAM is needed.
