The CWT Foam Cutter is a CNC hot wire foam cutting system designed specifically for sign shops, display fabricators, and dimensional signage producers. It cuts EPS (expanded polystyrene) and XPS (extruded polystyrene) foam sheets with a heated wire guided by computer-controlled motion, producing smooth, clean edges without dust or debris. The result is a precision foam core ready to receive laser-cut acrylic faces, painted finishes, or printed surfaces — making it the essential first step in producing acrylic-faced dimensional letter sets, painted foam sign letters, and contour-cut display elements. Available through Cutworx USA.

Which Foam Board to Use
Only polystyrene foam boards can be cut in a CWT Foam Cutter. A lightweight rigid foam board used for letters, logos, and foam signs — up to 30× lighter than PVC foam boards at the same thickness. Market names vary; ask for rigid polystyrene foam board in the right density for sign making.
Recommended
XPS & EPS for Sign Making
XPS (extruded polystyrene) and EPS (expanded polystyrene) at the right density produce the best results for dimensional sign letters, logos, and acrylic-faced applications.
32–40 kg/m³ · 2.0–2.5 lb/ft³
Can Also Be Used
Lower Density EPS
Lower density EPS foam can be used but may produce slightly rougher cut surfaces. Suitable for some applications but not ideal for premium acrylic-faced letter production.
30–32 kg/m³ · 2.0 lb/ft³
Temporary Use Only
Very Low Density EPS
Very low density EPS foam is not recommended for permanent signage. Suitable for temporary applications only — event props, short-term displays, and prototype work.
Below 30 kg/m³ · ~1.25 lb/ft³

- Faster cycle times for letter production
Production Workflow
From foam sheet to finished dimensional letter — the CWT Foam Cutter fits into your sign shop workflow at every stage.
Design & File Prep
Import your letter or shape artwork into the CWT software. Set depth, kerf, and profile parameters for the foam type and application — acrylic-faced, painted, or sculpted.
Load Foam Sheet
Place your EPS or XPS foam sheet on the cutting bed. The CWT Foam Cutter handles standard foam sheet sizes used in sign production.
CNC Hot Wire Cut
The CNC-controlled hot wire cuts through the foam with precision, following the letter or shape profile to produce a clean, smooth foam core with consistent depth.
Apply Face or Finish
Bond a laser-cut acrylic face to the foam core, apply paint and primer for a painted letter, or add texture coatings for a sculpted finish. The smooth hot wire surface bonds and accepts finishes cleanly.
Finished Letter Set
The result is a professional-quality dimensional letter set ready for installation — acrylic-faced, painted, or sculpted — produced faster and cleaner than any routing-based process.
Why Sign Shops Choose the CWT Foam Cutter
Precision, speed, and cleanliness — the three things sign shops need most in foam letter production.
Cleaner Than Routing
Hot wire foam cutting produces no dust, no debris, and no bit wear. The heated wire melts through EPS and XPS foam cleanly, leaving a smooth surface that requires no sanding before painting or applying acrylic faces — dramatically reducing prep time and keeping your shop clean.
CNC Precision
Computer-controlled motion ensures consistent letter depth, profile accuracy, and repeatability across full character sets. Whether you're cutting 3-inch lobby letters or 24-inch exterior signage, every letter in the set comes out identical — critical for professional dimensional signage production.
Complete Workflow Integration
The CWT Foam Cutter integrates directly into your sign shop's existing workflow. Pair it with a BRM CO₂ laser for acrylic face cutting and you have a complete, in-house production system for dimensional letter sets — from foam core to finished acrylic-faced letter — without outsourcing any step.

Frequently Asked Questions
What is a CNC hot wire foam cutter? +
A CNC hot wire foam cutter uses a heated wire guided by computer-controlled motion to cut through EPS and XPS foam sheets with precision. The hot wire melts through the foam cleanly, producing smooth edges without dust or debris — making it ideal for sign letters, foam cores, dimensional displays, and themed fabrication.
What is the difference between EPS and XPS foam for sign making? +
EPS (expanded polystyrene) is the white beaded foam used for large sculpted letters, themed elements, and lightweight dimensional displays. XPS (extruded polystyrene) is a denser, smoother foam that produces cleaner cut edges and is preferred for acrylic-faced letter cores and precision sign applications. The CWT Foam Cutter handles both materials.
How does hot wire foam cutting compare to CNC routing for sign letters? +
Hot wire foam cutting produces cleaner, smoother edges than CNC routing on foam, with no dust, no bit wear, and faster cycle times for letter production. It is particularly superior for producing foam cores that will receive acrylic faces, as the smooth surface bonds more cleanly. CNC routing is better suited for rigid substrates like PVC, aluminum, and wood.
Can the CWT Foam Cutter produce acrylic-faced letter sets? +
Yes. The CWT Foam Cutter is specifically designed to produce the foam cores used in acrylic-faced dimensional letter sets. The hot wire cuts the foam letter profile to precise dimensions, and a laser-cut acrylic face — typically cut on a BRM CO₂ laser — is then bonded to the foam core to create a finished acrylic-faced dimensional letter.
Where can I buy the CWT Foam Cutter in the USA? +
The CWT Foam Cutter is available in the United States through Cutworx USA, an authorized distributor based in Texas. Contact the sales team at 469-758-2288 or email sales@cutworxusa.com for specifications, consultation, and ordering.
