Smart Mold Design & Instant Quotation in Your Browser
Upload STEP files, analyze geometry, and generate quotes in minutes — no CAD software needed.
Injection mold intelligence, built for engineers.
From STEP upload to full mold quote in under 60 seconds — parting line, draft analysis, cavity layout, runner optimisation and costing in one offline-ready tool.
3D CAD Viewer
Rotate, zoom, and pan STEP / IGES files directly in your browser. WebGL-accelerated rendering.
Parting Line Analysis
Auto-detect optimal parting lines based on pull direction. Visualise split faces, undercuts, and shut-off surfaces in real time.
Draft Angle Analysis
Per-face colour map — green (good draft), yellow (min draft), red (no draft), blue (undercut). Adjustable pull direction.
Auto Mold Base Layout
Automatic multi-cavity layout — 1×1 to 8×8. Balances runner length, cavity pitch, and mold base size in one click.
Runner Layout Optimisation
Balanced vs naturally balanced runner systems. Gate type recommendation, pressure drop and fill-time estimates per cavity.
Instant Mold Costing
Material, machining, insert steel, hot runner, and overhead — full INR / USD breakdown generated from geometry in seconds.
Wall Thickness Map
Colour-coded surface map highlights thin walls, thick sections, and sink mark risk zones before tooling starts.
DFM Complexity Score
AI-powered complexity detection — face count, fill ratio, rib density — scored and categorised for instant quote accuracy.
PDF Quote Report
One-click export — mold dimensions, cavity layout, steel grades, cycle time, and cost breakdown as a professional PDF.
A real CAD environment. Zero install.
The same precision and tooling you expect from desktop engineering software — running entirely in your browser.

Injection Molding Companies
Quote inbound RFQs in minutes. Standardize geometry checks across every estimator on your team.
Tool Rooms
Visualize complex multi-cavity tools before machining. Spot interference and undercut issues early.
Product Designers
Share interactive 3D previews with manufacturing partners — no more sending massive STEP files by email.
Designed by engineers who hate slow quoting.
Most CAD software was built for a desktop era. MoldEngine treats the browser as a first-class engineering surface — fast, collaborative, and always up to date.
No CAD software required
Everything runs in the browser. Open STEP, IGES, and STL files instantly on any device.
Faster quotation turnaround
Cut estimate time from days to minutes with automated geometry-driven pricing.
Cloud-based collaboration
Share live viewer links with clients. Comment, annotate, and approve without exports.
Built for mold engineers
Purpose-built workflows for injection molding — not a generic 3D viewer adapted to it.
