The Practice of designing plastic products using computer-based finite element flow analysis software has become increasingly sophisticated since its conception in the late 1970’s. In order to produce accurate predictions it is essential to use the appropriate material properties data. Different materials, even of the same generic type, can behave in substantially different ways during processing. Modern software packages have material database systems that contain the necessary characteristics on many hundreds of thermoplastic, elastomeric & thermosetting materials, although they cannot cover every material a user is liable to consider.

Gammadot has two decades experience characterising both standard & novel grades of materials for flow simulation trials. We offer a portfolio of testing services aimed at providing accurate materials data for a wide variety of finite element flow simulation software packages including Moldflow & Sigmasoft 3D. In September 2009
Gammadot Rheology was awarded ‘Characterisation Partner’ status for the provision of materials characterisation data for Moldex3D – the flagship true 3D flow simulation software package developed by CoreTech System Co., Ltd (Taiwan).

 
We can provide data in the following formats:

Autodesk Moldflow
Sigmasoft 3D
Fillcalc V C-Mold Autodesk Moldflow Sigmasoft 3D
Simulation packages now discontinued but characterisation services still supported
