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.

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

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.
