extrucal 1.2.0

Provides functions for calculating various parameters in extrusion processes

extrucal

Author: John Lee

extrucal provides functions for calculating throughput in extrusion processes and for generating tables and plots for throughput with respect to screw RPM and channel depth in metering section.

A large portion of arguments for the functions were given the typical values. The arguments for functions are as follows: screw size, channel depth, polymer melt density, screw RPM, screw pitch, flight width, number of flights

Installation

extrucal can be installed PyPI using the following terminal command:

$ pip install extrucal

Package Functions

1. functions in extrucal.extrusion

• throughput_cal()

  • This function calculates the extrusion throughput (Drag Flow) given the screw size, RPM, the channel depth of metering channel, and screw pitch

• throughput_table()

  • This function generates a table containing the extrusion throughput with respect to channel depth and screw RPM

• throughput_plot()

  • This function generates a plot containing the extrusion throughput with respect to channel depth and screw RPM

2. functions in extrucal.cable_extrusion

• cable_cal()

  • This function calculates the required throughput for cables given the outer diameter, thickness, line speed, and solid polymer density

• cable_table()

  • This function generate a table containing the required screw RPM with respect to line speed and extruder size

• cable_plot()

  • This function generate a plot containing the required screw RPM with respect to line speed and extruder size

3. functions in extrucal.tube_extrusion

• tube_cal()

  • This function calculates the required throughput for tubes given the outer diameter, inner diameter, line speed, and solid polymer density

• tube_table()

  • This function generate a table containing the required screw RPM with respect to line speed and extruder size

• tube_plot()

  • This function generate a plot containing the required screw RPM with respect to line speed and extruder size

Usage

extrucal can be used to calculate extrusion throughput and to generate tables and plots of various parameters in extrusion processes
