Injection Moulding Simulation

Smithers Rapra has provided information & advice on Injection moulding for a variety of products & of varying complexities. Our consultants work regularly at the initial stages of product development including moulding & have developed an unsurpassed knowledge in this area.

The advice offered usually uses true 3D injection moulding simulation using 3DSigma software. This approach with our experience of product development, material choice & that of product & material failure ensures the support provided is based on a combination of simulation & actual moulding knowledge.

Optimisation of filling, Packing & Cooling

• Insert moulding
• Multi-shot moulding
• Sink mark reduction
• Weld line identification
• Ability to simulate thermoplastics, thermosets, rubbers, ceramic & metal injection moulding

Virtual Tool Validation

• Thermal simulation of the mould
• Multi-Cavity tooling
• Hot or cold runners
• Cooling channel simulation
• Optimisation of cycle times

3D Fibre Orientation

• The prediction of fibre orientation through the wall section
• Effects of ribs, inserts & holes
• The effects of anisotropic shrinkage & stress
• Exportation of fibre orientation to assessment by FEA

Residual Stress Simulation

• Optimisation & reduction of moulded in stress
• To minimise risk of product failure
• Assessment of stress around inserts
• Improvement of component life
• Export of residual stress for FEA analysis

Shrinkage & Warpage Simulation

• The prediction of 3D distortion
• Accurate dimensional analysis of mouldings
• Process optimisation to minimise distortion
• The export of moulded part geometry.
