1. Please note cool time starts

with end of inject and overlaps

with packing stage.

2. RTC temperature achieved

within overall cycle time.

3. Cool time estimated for

process driven maximum

temperature.

IMPORTANT DISCLAIMER: Because of the multiplicity of possible effects during the processing and use of different

brand resins, the information herein does not free the processor from carrying his own validation tests and experiments.

Our calculation does not provide legally binding assurances of specific performance or of suitability for a particular

application.



We have condensed published research from MIT and many notable

researchers to produce this plastics tool cooling evaluation algorithm.

Hope you gathered from this sample report that our proprietary software

produces most powerful, easy to understand and most practical plastics

simulation. This simulation is developed to help tool designers and process

personnel get the cooling design right, accurately predict cycle time with

eye for uniformity of cooling, sufficient cooling, stress-free part and

accurate prediction of shrinkage. This algorithm is equally accurate in

predicting temperature rise for Rapid Thermal Cycling tooling, demanded

by today’s most demanding moulding applications. All in one neat

package. Will love to here from you with your most demanding application.


Powerful, Simple, Practical.
