Simmetric Engineering Solutions

Injection molding decisions, before the mold is built.

Send the CAD, the material and the process data. Within a fixed time and at a fixed price, you get a simulation report that says what will happen in the mold, what to change and why.

Three studies. Fixed price, fixed delivery.

Fill Review

Can this part fill, and where should it be gated?from $150, within 24 hoursGate position, pressure, weld lines and air traps for one part and one material.

Thermal & Warpage

How much will it shrink and warp under your process?from $300, within 48 hoursFill, pack and warp under your process; shrinkage and deflection on the surfaces that matter.

Optimization Sprint

Which design or process alternative gives the best trade-off?from $600, within 1 weekA baseline plus up to 3 iterations, ranked; each extra iteration $150.

Every study includes the report described below. Delivery is counted from a complete input pack. Cooling analysis and other add-ons are scoped on request.

Recurring work? As your Dedicated Analysis Partner, Simmetric becomes the external analysis function: ongoing requests handled through one shared priority queue, with consistent assumptions and reporting. Contact us.

What you get

Every study ends in an English PDF report you can put in front of your team: the question, the model and its assumptions, the result images, prioritized findings and the next decision.

The team behind Simmetric

Simmetric is an independent injection molding simulation practice run by an experienced engineering team. Behind every study: analysis experience from 2,000+ projects for automotive, electronics and consumer-goods suppliers. Each study runs through an automated analysis pipeline with parallel solver capacity and is reviewed by a senior engineer before it leaves. Demonstration studies are published on this site.

Your files stay with the named engineers on your project, on our own encrypted machines. No cloud AI service touches them, and they are deleted 90 days after delivery with a written confirmation. How we handle your CAD and data

Nine studies you can read in full.

Total deflection of the rugged handheld housing, outer face, cold runner baseline

Rugged handheld housing: cold runner baseline and 3D hot runner

One housing, two feed systems: sealing-rim flatness 0.15 mm against a 0.30 mm target, and what a 3D melt volume changes.

 Total deflection contour of the 12-way connector housing, maximum 0.597 mm

12-way connector housing

A thin-wall connector with a modelled cold feed system and modelled cooling circuits: maximum total deflection 0.60 mm.

 Total deflection of the radial fan impeller, 0.04 mm at the hub rising to 0.681 mm at the rim

Radial fan impeller

Three gates instead of one on a nine-blade wheel, so the once-per-revolution imbalance cancels: maximum total deflection 0.68 mm.

 Total deflection contour of the headlamp rear housing, maximum 2.244 mm

Headlamp rear housing

Gate screening and a full 3D run on a 386 mm lighting housing: maximum total deflection 2.24 mm.

 Total deflection contour of the door module carrier, maximum 7.305 mm

Door module carrier

The largest part in the series and the broadest bow: maximum total deflection 7.31 mm.

 Total deflection contour of the center console bezel, maximum 1.262 mm

Center console bezel

A visible surface, a joining line above the shifter opening and a cosmetic-face bow: maximum total deflection 1.26 mm.

 Total deflection contour of the electronic control unit housing, maximum 1.493 mm

Electronic control unit housing

The sealing rim fills last and bows most on this enclosure: maximum total deflection 1.49 mm.

 Total deflection contour of the twenty-way connector, maximum 0.447 mm

Twenty-way connector

Twenty terminal cores, repeated joining traces and a solid latch root: maximum total deflection 0.45 mm.

 Total deflection contour of the radiator fan shroud, maximum 5.225 mm

Radiator fan shroud

Hub-first filling on a 524 mm shroud, frame-last movement: maximum total deflection 5.23 mm.

All parts are our own designs, built to show the method. None of them is paid client work.
