Injection molding and tooling-risk simulation

Injection Molding Simulation & Moldflow Analysis Services

FEAmax uses Moldflow analysis to evaluate filling, packing, cooling, warpage, shrinkage, gate design and tooling risk before mold changes or production trials.

What Is Moldflow Analysis?

Moldflow is a virtual molding trial before steel is cut.

Moldflow analysis predicts how molten plastic fills, packs, cools and shrinks inside a mold. It helps identify weld lines, air traps, sink marks, pressure risk, shrinkage and warpage before physical mold trials.

Used early, Moldflow can reduce tooling risk, improve gate and runner design, reduce trial-and-error iterations and support better decisions for part design, mold design and production process setup.

Moldflow Project Workflow

A structured process from part review to manufacturability recommendations.

01

Review Part and Molding Objective

FEAmax reviews CAD geometry, material information, gate assumptions, tooling constraints and the main manufacturing concerns.

02

Confirm Process Assumptions

Material, gate, runner, cooling, process conditions and output expectations are clarified before the simulation setup.

03

Prepare Mesh and Mold Setup

The part or casting geometry is meshed, thickness and flow paths are reviewed and critical features are checked.

04

Run Fill, Pack, Cool and Warp

The analysis evaluates filling, packing, cooling, shrinkage, warpage or casting behavior depending on the project scope.

05

Review Defects and Tooling Risks

FEAmax reviews weld lines, air traps, pressure, shrinkage, hot spots, cooling balance and dimensional risks.

06

Deliver Recommendations

The final report summarizes risks, result images, gate or tooling comments and practical improvement recommendations.

How Moldflow Accuracy Is Controlled

Useful Moldflow results depend on material, geometry, process and tooling assumptions.

Material Data

Resin, filler, fiber and temperature-dependent material data affect filling, pressure, shrinkage and warpage predictions.

Mesh and Wall Thickness

Accurate wall thickness, ribs, bosses and mesh quality are critical for predicting flow, pressure and local risk areas.

Gate and Runner Setup

Gate number, location, size and runner balance strongly influence fill pattern, pressure, weld lines and air traps.

Cooling System Definition

Cooling channel layout, coolant temperature and mold temperature affect cycle time, shrinkage and warpage.

Process Parameters

Fill time, melt temperature, packing pressure, mold temperature and switch-over settings should match realistic processing.

Manufacturing Judgment

Moldflow results must be interpreted with part design, tooling feasibility, supplier constraints and production goals in mind.
