INTRODUCTION

TO

NAUTILUS 2012

MOLD QUALIFICATION

AND

DESIGN OF EXPERIMENTS SOFTWARE

FOR

INJECTION MOLDING

NAUTILUS IS A PROGRAM THAT HELPS IN THE

EVALUATION, ANALYSIS, DEVELOPMENT AND

DOCUMENTATION OF THE INJECTION MOLDING

PROCESS.

THE SOFTWARE ALSO HAS A COMPLETE DESIGN

OF EXPERIMENTS MODULE THAT IS CUSTOMIZED

FOR INJECTION MOLDING

FOLLOWING ARE SOME OF THE FEATURES OF THE SOFTWARE:

� MATERIAL, MOLD AND MACHINE DATABASES

� MOLD – MACHINE COMPATIBILITY REPORT

� SCIENTIFIC MOLDING WORKSHEETS (6-STEP STUDY)

• VISCOSITY STUDY

• PRESSURE DROP STUDY

• CAVITY BALANCE STUDY

• PROCESS WINDOW STUDY

• GATE SEAL STUDY

• COOLING TIME

�DESIGN OF EXPERIMENTS MODULE

• TORNADO CHARTS – WHAT IS THE MOST SIGNIFICANT FACTOR?

• PROCESS SENSITIVITY CHARTS

• COSMETIC PROCESS WINDOW

• DYNAMIC PROCESS WINDOW

• VISUAL PREDICTION EQUATION

� MOLD TRIAL AND QUALIFICATION PROGRESS REPORT

� WATER LINE DIAGRAMS AND MOLD TEMPERATURE MAPS

� MOLD SETUP AND OPERATION DOCUMENTATION

�QUALITY MODULE

• FULL DIMENSIONAL ANALYSIS

• STATISTICAL ANALYSIS

• POST MOLDING SHRINKAGE REPORT

• DOCUMENTATION OF QUALITY INSPECTION PLAN

� MOLD DESIGN AND PART DESIGN CHECKLISTS

� CALCULATION WORKSHEETS COMMONLY USED IN MOLDING
