CNC foam milling and engraving – foam cutting

Summary: What is the foam milling and engraving?

The foam milling is a process of manufacturing a physical component made of a foam using a computer precision 5 axis foam milling machine to engrave the components of the foam block. This process requires any file format in the 3D model CAD file: STL, OBJ, STEP / STP, or IGES / IGS.

The foam milling machine is a process of manually engraving the foam to achieve complete physical results, closely related to the image reference provided by customers. Hand-engraved foam is more accurate than CNC milling machine, but for most types of display, landscape or any object that does not require engineering accuracy is fully applicable.

how long does foam milling machine work?

Most single order is completed within 2-4 days after production. Large-scale, oversized or orders may take longer. All price quotes contain an estimated extension time.

What foam do you have?

Two options: EPS polystyrene foam and high density polyurethane foam (HDU).

Foam milling machine is an economical choice for universal foam models with low complexity, while HDU foam is significantly, suitable for parts that require high definition and sharp surface detail.

What is the difference between CNC foam milling and manual engraving?

If you have a CAD file, your part can use the computer-controlled 5-axis foam milling machine production, based on 3D data, high-precision core, high-precision core, based on the CAD file. The CAD file should be used in the following file format: STL, OBJ, STEP / STP, or IGES / IGS.

If you don’t have a CAD file, the artist can reference the engraving foam portion according to the image provided. The detail will be accurate based on the interpretation of the image reference provided to the image.

If you don’t have a CAD file, you do need a 5 axis foam milling machine accuracy, we offer 3D design services to create the CAD files required for this process based on your draw / size / image.

Can you make large (or small) in the foam?

Foam grinding is a good choice for the production of parts, otherwise the standard capability of more than 3D printing. If your model is relatively small, this may not be a good application of foam milling machine because 3D printing may be more cost effective and will have a stronger and more accurate part of the material in plastics.

5 axis foam milling machine or hand engraving has no real maximum allowable size because large foam parts can be constructed together in segment and pin + combination.

I need painted + complete my foam part. Is that possible?

We can add polyurea epoxy spray coating to the foam portion to give them a sand shell and completed hard shell. This epoxy hard coat layer is ~ 1/16 “thick, with a slightly protracted” orange skin “texture, which can be smooth to prepare surface painting.

Common application of foam milling machine

Styrene foam plastic EPS parts

Create a polystyrene foam model in any shape and size. This EPS foam material is a lightweight, for a good choice for models without fine or complex detail.

HDU polyurethane foam model

Polyurethane foam is a more intensive, more powerful material option, suitable for models that require more fine or more complex detail. Optis contains 4-lb and 6-LB polyurethane foams.

Hard coat

Apply the CNC foam model with a hard chain oxygen shell surface, so it can be smooth and painted.
