Ambix Consulting, LLC · Plastics engineering since 2001

Plastics engineering from first sketch to final shot.

We design plastic parts and the molds that make them, develop the processes that run them, and find out why parts fail. Bring us a new product or a part that has gone wrong, and we will get it into production or back on track.

Services

Design it right. Mold it right. Keep it running.

Most of our work is new product design, part optimization and injection mold construction. Every service draws on the same advantage: we also run a molding plant, so our advice reflects what happens on the press, for the molder and for the OEM.

Product design and design for manufacturing

You have a concept, a prototype or a drawing, and need a part that molds well and lasts.

We start with your requirements: tolerances, assembly, environment, service life, electrical and UV criteria. Then a materials review, a design review backed by simulation, and a manufacturing plan with cycle times and costs.

You receive
  • Production-ready CAD (Onshape, SolidWorks)
  • Material recommendation with rationale
  • DFM review and simulation results
  • Cost analysis at your volume breaks

Mold design and construction

You need tooling that runs from the first shot and grows with your volumes.

Hot runner, multi-cavity, collapsible and unscrewing cores, hand-load inserts, and compression molds for phenolics and other thermosets. We design modular molds with interchangeable inserts for product families, and plan bridge tooling that can take more cavities later.

You receive
  • Mold design, in-house or through our partners
  • Build managed with domestic or overseas toolmakers
  • First-article sampling and measurement
Production mold with cooling lines mounted in an injection press

Process development

Scrap is high, cycles are long, or the process will not hold.

A scientific molding approach on our presses or yours. We baseline the existing process, auxiliaries, cooling and heaters, then run an efficient DOE to set a robust window for ongoing production.

You receive
  • Documented process window and setup sheets
  • DOE data behind every setting
  • IQ/OQ/PQ validation support when needed
Injection molded plastic gears

Failure analysis and root cause

Parts are cracking, warping or failing in the field.

We collect the evidence, direct testing through our regional lab network (FTIR, DSC, TGA, SEM, GC/MS, mechanical) and interpret it ourselves. Then we change the material, design or process to remove the cause.

You receive
  • Evidence-based root-cause report
  • Corrective action in material, design or process
  • Verification that the fix holds

Material selection and metal-to-plastic conversion

Your resin is discontinued or too costly, or the part needs to be lighter.

Establishing equivalency for an alternate or backup resin takes real testing. We qualify substitutes for cost, supply-chain or performance reasons, and convert metal parts to plastic, such as multi-step machined stainless replaced by one-shot carbon-fiber PEEK.

You receive
  • Qualified material with test data
  • Process adjustments for the new resin
  • Weight and cost comparison

Reverse engineering, onshoring and training

You have a sample and no drawings, a mold coming home from overseas, or a team that needs to grow.

We 3D-scan parts and rebuild them as fully parametric models, then go straight to mold and production. We bring offshore molds back, adapt them to US standards and repair them. We also train operators, technicians and engineers.

You receive
  • Parametric CAD from a physical part
  • Molds reworked and running in the US
  • Training in molding, extrusion and materials

From requirements to a running process

Every decision is backed by data before steel is cut. You can engage us for one step or the whole path.

  3. 03

    Design review

    Simulation and analysis test the design for performance and moldability.

    Secondary operations, inserts, cycle times and cost at each volume.

  5. 05

    Mold design and build

    Scalable tooling, built by our network and sampled on real presses.

  6. 06

    Process and production

    A validated process, handed to the molder you choose.

Failure analysis

We find out why, then we fix it.

You never know what will come through the door: a cracked housing, a seal that swelled, a part that warped on a hot loading dock. Jeff trained on the instruments that answer these questions early in his career, and has led failure investigations for medical, pharmaceutical, electrical and industrial clients since.

A lab report tells you what failed. We take the next step: a change to the material, design, mold or process that stops it from happening again, proven on a press.

Problems we have solved

Client names are withheld. Each case followed the same path: define the goal, find the cause, change what needs changing, and measure the result.

Electrical · powerFailure analysis
FIELD FAILURE RATE · DRAWN TO SCALE 50% WORST CASE <0.1% AFTER THE FIX

Field failures on a high-voltage safety consumable

Problem
A critical consumable used in high-voltage power installation and service varied widely in performance and sometimes failed catastrophically in the field.
Approach
A six-month investigation of the tooling, process capability, materials and the interactions between molded components in the assembly. Fixes combined mold improvements, process and tolerance control, and an upgraded material.
50% → <0.1%Field failure rate, worst case to after the fix. Ongoing process control has pushed it lower since.
Electrical distributionTooling strategy
MOLD BASE + INTERCHANGEABLE INSERTS A B C … ≤10 MINCHANGE 13 MOLDS · 5 PRODUCTS

Five products, dozens of variations, one tooling budget

Problem
A new product launch needed five products with 10 to 15 variations each. Conventional tooling meant a mold per part, far beyond the program's budget.
Approach
We designed and built 13 molds with hot-swappable inserts. Inserts change in 10 minutes or less, so production can group parts efficiently and keep piece prices low.

TEE FITTING · SECTION CF-REINFORCED PEEK MOLDED IN ONE SHOT WET SOUR GAS H₂S ≤8% · CO₂ ~9% STEEL / BIMETAL

Corrosion-proof fittings for wet sour gas

Problem
Wet sour gas from wells in northwest Germany carries up to 8% H₂S and nearly 9% CO₂. Wellhead dehydration accounts for about 23% of production cost, and piping the gas wet to central processing required expensive steel or bimetal lines.
Approach
We designed and injection molded highly reinforced PEEK fittings to replace metal, cutting weight and eliminating corrosion.
Steel → PEEKLighter fittings with no corrosion, at lower cost.

EXTRUDED TUBE · LONG SECTION CLEAR, CHEMICALLY RESISTANT WALL ACTIVE INGREDIENT + PROPELLANT METERED VALVE

Clear tubing that holds up to its own contents

Problem
A spray product for dog training and bark control needed transparent extruded tubing to hold its active ingredients and propellant in a metered delivery system.
Approach
We selected a tough, chemically resistant, optically clear material and qualified it with short-term, mechanical and long-term exposure testing.
QualifiedReleased to production for a demanding chemical and performance environment.

About

Senior expertise on every project

I'm a plastics engineering generalist. When a project needs deeper specialty, I bring in the right people from a network built over 30 years.

Jeff started his consulting career at Altran Corporation in Boston right after earning his plastics engineering degree. After completing his master's, he co-founded Mantis Associates, delivering failure analysis and product development to pharmaceutical clients worldwide. He founded Ambix in 2001 to focus on what he does best: plastic parts, the molds that make them, and the processes that run them.

Jeff leads every engagement. Simulation specialists, toolmakers, machine shops and test labs from the Ambix network join when a project calls for them.
