As a step in the process of shortening the lead time and avoid costly modifications due to poor design and execution. Eastrock Mould is using Moldflow Mold Advisor to simulate the plastic injection molding process. In addition we conduct cooling analysis, and shrinkage & warpage analysis.

High fill pressure, short shots, high gate shear, poor cooling, long cycle times and distortion problems are quality decisive issues that can be highlighted and fixed before construction begins.

The software offers the mold designer the best reference solution to analyze the injection process before the mold is built, to determine what changes are needed and greatly reduce the tooling development lead time.

The 3D flow simulation includes:
Fill time
Injection pressure
Temperature analysis
Flow balancing
Gate and feed system design
Optimizing part geometry
Optimizing and refining wall thickness
Fiber analysis
Gas injection simulation

By utilizing filling analysis the processing characteristics of an injection mould can be investigated and optimized at the design stage. Improvements in part quality are achieved by:
Refining gate points
Repositioning of weld lines
Eliminating gas traps
Reducing in balancing pressure
Reducing stress levels

A mould cooling analysis is conducted to find the optimum cooling channel and layout, range for the mould surface temperature, and to simulate hot runners and inserts.

Shrinkage and warpage analysis reduces the risk of assembly problems due to inaccurate moulding. Warpage analysis is also very useful as an investigating tool for existing moulds, to find a practical solution to distortion problems.
