An EPS mold must be designed around steam, drainage and the machine.
Fundimoldes integrates cavities, steam systems, closing, drainage, demolding, machining, assembly and maintenance to deliver tooling compatible with your process.
What is an EPS foam mold and when do you need one?
It is the metal tool where expanded polystyrene beads fill the cavity, expand with steam and fuse into the shape of the part. Each EPS foam part, whether a corner protector, appliance packaging or an insulation piece, needs its own mold.
To produce lightweight EPS parts in series: custom protective packaging, protective shipping inserts, insulation parts and lightweight technical components.
When the part has its own geometry that cutting foam blocks cannot achieve and production volume justifies tooling. If your product needs custom protective packaging, the mold is the starting point. See how custom EPS foam packaging is made.
Fundimoldes designs and builds the mold: cavities, steam chambers, drainage, closure and demolding. The foam parts are then produced with that mold on an EPS shape molding machine, usually at the customer’s plant or their molder’s.

How we work.
We review the part, target density, machine, steam, closing, injection, drainage and operating conditions.
We define cavities, structure, steam distribution, connections and demolding elements.
We manufacture components in cast aluminum, machined aluminum and other specified elements.
We integrate closures, injectors, connections and auxiliary systems.
We check dimensions, closing and steam conditions within the agreed scope.
We provide maintenance, repairs, spare parts and modifications.
Technical considerations.
The equipment’s dimensions, closing system, connections, steam, air, vacuum and mounting references are essential.
Condensate removal and part release affect cycle time, finish and stability.
We work with cast aluminum, machined aluminum and stainless steel components.
The trial must define material, density, parameters, cycle time and acceptance criteria.

Common questions.
Can you copy an existing EPS mold?
Yes, using drawings, on-site survey, 3D scanning and evaluation of your equipment.
Do you make spare parts and injectors?
The service can include custom components, based on a sample, drawing or reverse engineering.
What machine data do you need?
Usable area, closing system, connections, steam, vacuum, air, mounting, stroke and equipment constraints.
Do you maintain EPS molds?
Yes. Fundimoldes offers diagnostics, maintenance, overhaul, modifications and spare parts.
Is EPS the same as Styrofoam?
In everyday language, white protective foam is often called Styrofoam. Technically it is EPS, expanded polystyrene, molded with steam in a dedicated mold.
Does Fundimoldes make the foam parts or the mold?
Fundimoldes designs and builds the mold. The parts are produced with that mold on an EPS molding machine. If you haven’t decided where the parts will be produced, say so when requesting a quote.
