At Istar Machining, we provide foam CNC services to many different industries:
Let’s look closer at what foam CNC machining can do and how Istar Machining makes it happen!
At Istar Machining, we work with foams from super soft (1 lb/ft³) to very firm (40 lb/ft³). This means we can make anything from soft packaging to sturdy molds.
Real-world example: We recently made lightweight foam cores for an aerospace company that needed testing models. The foam was light enough to handle easily but strong enough to stand up to wind tunnel tests.
Our machines can cut foam with amazing accuracy – as precise as ±0.005 inches! That’s about as thick as a piece of paper.
Did you know? We use special tools for each type of foam to get the cleanest cuts possible.
Need something big? No problem! Our machines can handle foam pieces up to 12 feet long, 6 feet wide, and 4 feet tall. That’s bigger than most cars!
Cool project: We once made giant foam letters for a movie premiere that were 8 feet tall but light enough for two people to carry.
When you need things fast, our foam CNC machines can deliver. We can process hundreds of foam sheets each day for high-volume jobs.
Time-saving fact: Foam CNC machining is about 5 times faster than hand-carving the same shapes.
Our 5-axis machining equipment can create complex shapes with undercuts and detailed features that simpler machines can’t make.
Amazing application: We made detailed automotive seat prototypes with ergonomic curves that helped a car manufacturer test comfort before making expensive production molds.

Getting started is easy! Just follow these simple steps:
Think of it like a super-smart robot that can carve foam into any shape – from simple blocks to complex 3D designs. This is perfect for making prototypes, models, packaging, and many other cool things.
It depends on the foam type. For XPS foam, we can cut details as small as 0.06 inches. For polyurethane foam, about 0.12 inches is the limit.
Most projects are done in 3-5 business days. Rush orders can be completed in 24 hours for an extra fee.
Hot wire cutting uses a heated wire to melt through foam, which is fast but limited to straight cuts or simple curves. CNC routing uses spinning cutting tools that can create much more complex shapes with detailed features.
Yes! We can apply special coatings to foam parts that make them weather-resistant. We can also recommend foam types that naturally resist UV damage.
3D printers create amazing objects, but they have significant limitations. Understanding what 3D printers cannot do helps you choose the right manufacturing method. Here’s
Engineering drawings and CAD (Computer-Aided Design) are both used to design and manufacture products, but they differ significantly in format, creation, and application.
Choosing the right metal for your project is crucial. Titanium and aluminum are both lightweight metals widely used in various industries. This guide compares their properties to help
