Moxietec — The Future of Foam
The Future of Foam

Moxietec is a vertically integrated, technology-driven company.

We develop the foaming technology that takes mass out of high-performance parts — and we take them from concept to a running production line, all under one roof.

Right now we are developing a humanoid robot part to mold live at NPE2027 — our foaming technology, standard Covestro resin, an ENGEL machine. One seat is open — for the robot manufacturer.

What vertically integrated actually means

Bring us a sketch on a napkin. We will take it to a production line.

A concept, a CAD file, or a part you already mold today — we pick it up wherever it is. Product design, formulation development, mold design and mold manufacturing all happen on one campus in Pennsylvania, USA. No hand-offs between vendors, and nothing subcontracted.

And if you want the line automated — machine, mold and robot cell together — we can build you that too.

Where we have done it

A track record in high-tech, value-added parts.

Moxietec foamed structural locking blocks
Building & construction
Structural blocks, less resin per unit

Thick-walled, stiffness-driven parts where the foamed core takes out material — and improves compression strength and dart-drop impact.

Foam-molded field hockey sticks
Sporting goods
Impact protection with a finished face

Energy absorption and a cosmetic surface delivered in a single molded part, replacing a multi-piece assembly. We help make the world's strongest contact sports equipment.

Foamed automotive coolant reservoir
EV & robotics
Mass out of moving assemblies

Weight removed from parts that move constantly, without giving up the stiffness the assembly depends on.

Proven partnership

We have done this with ENGEL before. Twice.

In 2025 we ran joint demonstrations of foam injection molding on ENGEL equipment at two shows — K Show in Düsseldorf and PT Expo. Moxietec brought the technology; ENGEL brought the machine.

Both were very well received — and they are why the two of us are building something bigger for NPE2027.

Now — what is this technology?

Foaming, and why ours is different.

Solid wall
Solid resin throughout. Every gram carries load — most of it needlessly.
Foamed wall
Micro-cellular foam core, magnified
Solid skin, closed-cell core. Same outer surface, less mass inside.
The same thing in a real part

Two molded blocks broken open. The outer surface is solid and finished; the core is cellular all the way through.

As the part is molded, a controlled cellular structure forms inside the wall. The skin stays solid and cosmetic. The core becomes a honeycomb of tiny closed cells.

You remove material from where it does the least work — so mass and material drop while stiffness stays where the part needs it.

more impact energy absorbed than solid, with 39% less peak force transmitted
Lighter, faster to mold, and it took more impact energy than the solid part it replaced. Glass-filled nylon is one of the hardest materials to foam well — fiber distribution and cell structure fight each other.

Solid and foamed, side by side
The same part molded two ways. On the left, conventional and solid. On the right, foamed and sectioned — the closed-cell core replaces the material the part does not need.

Left: conventional — solid throughout, full mass.
Right: foamed — closed-cell core, same outer form.
Not all foam is the same

Conventional foaming gives you large, irregular, connected voids — which is why it has a reputation for weakening parts. Moxietec's formulations produce small, uniform, closed cells. Same idea, different physics, opposite result.

It holds a screw better than solid

The first question an engineer asks about a foamed core is whether it will hold a screw. The answer surprises people: pull-out strength goes up, not down. The cell walls give the thread thousands of edges to grip, where solid material offers one smooth face. Tested across fastener types as part of process development.

Cell structure is engineered, not accidental
One resin, twelve formulations to reach the right custom PFA — ten of them shown here, SEM at 2 mm scale. As the custom formula is tuned to the resin and the part requirements, cell size drops and the structure becomes uniform. Number 11 was the one.

Coarse, elongated cells

Early packages: large voids, thin walls between them, structure that varies across the section.

Fine, uniform cells

Tuned packages: small cells, consistent distribution — that fine, even cell wall is what carries load and impact energy at reduced density.

Why it matters to you

This is the work an evaluation does — your resin, your geometry, screened before anything trials at your plant.

What this actually takes

The additive is where it starts. It is not where it ends.

Our PFA does the hard chemistry — nucleating a fine, even cell structure in resins that fight it. But no additive can tell you what temperature, pressure and injection speed your part needs. Those settings are intellectual property in their own right, developed part by part, and they are what turn a strong formulation into a part that performs.

It runs on standard injection molding equipment — no special press, and existing tooling can often be used as it is. When a new tool is being built, we design the mold for the process too, so nothing is left to chance.

See how that runs, concept to production →
Turnkey — one
Mold design

The tool is designed for the foaming process from the first sketch — gating, venting, cooling and surface decided together.

Turnkey — two
Formulation development

Not a product off a shelf. The PFA is formulated for your resin, your wall thickness and your target density — and it is one element inside the formulation, not the whole thing.

Two customers on the same resin get two different formulations — each tuned to raise part performance and lower molding cost. That is the difference between buying an additive and being given a technology.

Turnkey — three
Process development

Temperature, pressure, injection speed — established part by part, documented, and repeatable on production equipment.

It runs in the resins you already use
Including high-temperature engineering resins, where foaming is hardest and the weight is worth the most.
Nylon (PA6, PA66) Glass-filled to 50% PPS Liquid crystal polymer Polycarbonate PC/ABS Polypropylene Polyethylene Polystyrene TPU PVC Recycled feedstocks
Filled or unfilled, virgin or recycled. Bring us your material and we develop the formulation around it — we do not ask you to change resin to suit the process.

Speed to market

This is what turnkey actually buys you:

Time.
2–3 weeks to build you a new tool — not months.
Money.
Mold modifications machined in-house — not quoted, shipped and waited on.
Four vendors means four queues, four quotes and four people to chase. One roof means the next step starts the same week.

Timings depend on part complexity and whether a new tool is required. Ask us for a schedule against your specific part.
Start wherever you are

A sketch, a CAD file, or a part you already mold today — we pick up from there.

Nothing is subcontracted

Formulation, design, tooling and process all sit with one accountable team — so when something needs to change, it changes.

Or take the whole line

We do not only develop the part. We can sell you the line that makes it.

Machine, mold, foaming formulation, process settings and the robot cell around it — specified, built, installed and validated as one package, with ENGEL. Others assemble a line from equipment they buy in; the lightweighting technology inside ours is our own. You get a line already making good parts, not a pile of equipment and four suppliers to coordinate.

Bring us the part you most want to make lighter.

Send us the part. We will assess it against our foaming technology and come back with whether it is a fit, and what the weight and cycle-time reduction would be. If it is, we can take it from there — to trial, to tool, to production.
