Defect Diagnostics

Hover over a defect
point to diagnose.

Short Shot Risk

Incomplete plastic fill defect where the cavity is not fully packed, often caused by inadequate pressure.

Weld Lines

A critical structural weakness caused by two or more flow fronts meeting and failing to fuse completely.

Air Traps

Pockets of air compressed inside the cavity that cannot escape, leading to unsightly burn marks or voids.

Sink Marks

Shallow surface depressions caused by uneven cooling and localized volumetric shrinkage in thicker sections.

Hesitation Zones

Thin wall areas where the polymer flow stalls or drastically slows down, causing premature freezing.

Race Tracking

Uneven flow progression where molten polymer rushes through thicker sections, trapping air in thinner areas.

What is Mould Flow Filling Analysis Services India?

CAE Simulation (FEA & CFD) is the numerical modeling of physical systems to predict structural stress, thermal dissipation, fluid flow, crashworthiness, and dynamic fatigue life under real-world operational loads.

When to Select This Service

Choose CAE simulation during early product development to virtually validate design integrity, optimize part weight, verify safety factors, and eliminate physical prototype failure risks before committing to production tooling.

FAQ

Frequently Asked Questions

What information is required to start an FEA or CFD simulation?

We need 3D CAD files (STEP/Parasolid), material specifications, operating boundary conditions (forces, pressures, temperatures, constraints), and load cases (static, cyclic, or dynamic impact).

How do you validate the accuracy of simulation results?

We follow NAFEMS simulation guidelines, perform mesh convergence sensitivity studies, apply realistic physical contact formulations, and correlate models against physical test data where available.

How can Moldflow simulation save tooling costs for plastic parts?

Moldflow identifies potential defects like air traps, weld lines in high-stress zones, short shots, and excessive warpage before cutting tool steel, saving weeks of tool rework and thousands of dollars in tooling modifications.

Can you optimize parts for lightweighting and material reduction?

Yes. We perform topology optimization and parametric sizing to redistribute material according to principal stress trajectories, achieving 15% to 40% weight reduction while maintaining target safety factors.

What is included in the final simulation report?

The report provides an executive summary, methodology description, boundary condition diagrams, stress/strain/displacement distribution plots, safety factor evaluation, and clear design modification recommendations.
