What is Foam Moulding?
Foam moulding is a manufacturing process that injects gas-impregnated plastic into a mould, creating parts with a lightweight foam core and a dense, rigid outer skin. This process delivers high strength-to-weight ratios, excellent durability, and design flexibility, making it ideal for large, complex components that traditional injection moulding cannot achieve. Foam moulding is widely used in industries such as automotive (lightweight panels, enclosures), construction (insulated panels, durable housings), medical (equipment casings, ergonomic supports), and industrial applications (storage containers, machine housings).

The Easiest Way To Manage Your Projects
1. Submit Your Foam Moulding Enquiry
Upload your designs, select the quantity, materials, surface finish, and other parameters, then submit a quote request.
2. Review and Quoting
A Xometry engineer reviews your enquiry within 24-48 hours to ensure all requirements are met. You receive an initial quote. Upon your approval, our engineers match your project with the most suitable manufacturer based on skills, availability, and other criteria. We then send you a final quote.
3. Project Kick-Off and DFM
Once you approve the final quote, you receive an order confirmation and an invoice for 50% of the mould costs. After that we start the Design for Manufacturability (DFM) process. Xometry works with you to clarify and finalise all technical details before proceeding.
4. Mould Building and Sample Production
After finalising DFM, we set deadlines for mould building and first sample production (T1). Our project manager oversees logistics and communication. You receive the T1 samples with a measurement report for approval. Feedback on the T1 samples should be received within 10 days and if further improvements might be required, further iterations (T2, T3, etc.).
5. Full Production and Delivery
Once samples are approved, Xometry manages full-scale production, quality control, and part delivery. You pay the production costs upon receiving the parts.
6. Mould Ownership and Re-Orders
The mould lifespan is between 10,000 to 1,000,000 shots. The mould is owned by you and maintained by Xometry. The customer can easily re-order parts whenever required.

Available Materials for Foam Moulding
Plastics
- EPP (Expanded Polypropylene)
- EPS (Expanded Polystyrene)
- EPO (Expanded Polyolefin )
- EVA (Ethylene Vinyl Acetate)
As-formed
As-formed parts retain the natural surface texture and appearance that results from the mould.
Sand blasting
Sand blasting is a surface preparation technique involving high-velocity abrasive particles to remove contaminants and roughen surfaces.
It’s commonly used for cleaning, texturing, or preparing plastics for processes like painting.
Custom
If you select a custom finish in the Instant Quoting Engine it will require manual review. Manual quoting usually 1-2 business days.
Submitting for manual review with a custom request does not guarantee a quote.

“We very much appreciated the speed of the platform: in zero time, I can get a quote for 1, 10 or 100 pieces, and test how much it might cost to produce with one material over another, which is crucial in the design phase but also to make realistic proposals for our customers.”
Frequently Asked Questions
Foam moulding is a manufacturing process that uses gas or chemical blowing agents to create lightweight, durable, and impact-resistant foam parts. This method is commonly used for protective packaging, insulation, cushioning, and structural components. Foam moulding is widely applied in industries such as automotive, aerospace, construction, medical, and consumer goods.
Products made through foam moulding include packaging inserts, insulation panels, automotive seating, and custom-shaped cushions. This process is ideal for producing lightweight components with excellent shock absorption, thermal insulation, and sound-dampening properties.
Common materials used in foam moulding include polyurethane (PU), expanded polystyrene (EPS), expanded polypropylene (EPP), and polyethylene foams. Each material offers different benefits, such as flexibility, rigidity, or high impact resistance.
Yes, we specialize in custom foam moulding, allowing us to create parts with unique shapes, densities, and mechanical properties tailored to your specific application. We can also provide design assistance to optimize your parts for cost and performance.
The maximum part size depends on the material and moulding method. Large-format foam moulding is possible for applications such as protective packaging, insulation, and structural components. Contact our team to discuss your specific size requirements.
“What amazed me about Xometry is a very empathetic approach, almost ‘micro-business style’, despite being a multinational: the ability to adapt to customer needs, with great responsiveness, and to immediately create a relationship of mutual trust.”
Mario Boaglio, Sferasol
“Discussions with my Key Account Manager about the gear knob were crucial in finding the best manufacturing process and achieving a result that was as close as possible to a production part. Unlike other companies and suppliers, I actually got to deal with a human contact.”
Stephane Develter, Develter
“With Xometry, it helps that there is an algorithm to instantly provide a price and a binding quote when you upload your part design. I thought that was amazing. Then you just complete your order and get a delivery date, which was met in our case. Wow, what a great process to work with!”
Thomas Kern, Atmos
“Collaborating with Xometry has put us in a strong position to make progress, particularly with mass production. Being able to outsource has significantly reduced our workload and we can still easily maintain quality and meet deadlines.”
Vincent Dufour, Neocean
“Xometry has provided us with great support in the CNC manufacturing of our MCU prototype enclosures, for both very small and medium-sized batches. Xometry’s customer support also ensures the right high-quality parts are delivered to the right location in record times on a very direct and personal basis.”
