Mould filling analysis. The filling phase of the injection moulding process greatly affects the quality of the end product.

By utilising filling analysis the processing characteristics of an injection mould can be investigated and optimised at the design stage. Improvements in part quality are achieved by refining gate points, the position of weld lines, eliminating gas traps, balancing pressure drops and reducing stress levels.

A mould filling study provides solutions to questions such as: How does the mould fill? How many injection points? How much pressure? What clamp tonnage machine is required? Is it possible to reduce the wall thickness?


The benefit to you!

Investigating the mould filling characteristics of an injection mould using moldflow simulation technology highlights potential problems before they actually occur. This enables our engineers to develop a practical solution while the mould design proceeds.

Mould filling analysis.
We first convert the Cad model into a finite element model which includes all principle detail and thicknesses. A number of practical gate options are analysed to calculate the optimum gate position and feed system requirements. "Click for Cooling analysis"


A Mold Flow simulation highlights most quality problems including :- High fill pressure, Short shots, weld lines, Gas traps, High gate shear, Poor cooling, Long cycle times and Distortion.
