Foundry Model Making with Strafor – Precision, Innovation, and Efficiency in Modern Casting Technology

CNC-Machined Foam Models for High-Quality Cast Components

Evomatec’s foundry model making with Strafor (EPS, Styrofoam, rigid foam) represents the forefront of modern pattern technology in precision casting. Our high-resolution CNC-milled foam models made of Strafor, Styrodur, or polystyrene are engineered for advanced foundries and metal casting plants seeking maximum dimensional accuracy, surface quality, and form stability.

Combining digital CAD/CAM design, 5-axis CNC machining, and heat-resistant rigid foam materials, Evomatec produces prototype, single, and serial casting models with unmatched precision and efficiency. Whether for lost foam casting, ceramic molding, or foam model foundry processes, Evomatec provides the complete solution – from design analysis to fully finished, ready-to-use models.

Precision Model Making for Castings in Rigid Foam, Styrofoam, and EPS

Our rigid foam foundry models are characterized by excellent dimensional stability, low weight, and optimal thermal resistance. The material Strafor (expanded polystyrene) is ideal for precision casting processes, as it melts away cleanly, leaving behind an exact and residue-free cavity in the mold.

This method is especially effective in lost foam casting and is widely used for aluminum, steel, and iron castings. Through CNC machining, Evomatec creates detailed geometries – from core model design to complete EPS or Styrodur mold assemblies – ensuring flawless casting accuracy.

Advantages of Evomatec’s Foundry Model Making Technology

1. CNC Precision with Digital Design

All foundry models are digitally engineered in 3D CAD environments. Customer data in STEP, IGES, or STL formats is transferred directly to 5-axis CNC machining centers, enabling high-precision foam milling and exact replication of model geometries.

2. High-Quality Rigid Foam Materials

Evomatec uses only certified materials such as Strafor, EPS, Styrofoam, Styrodur, and PU rigid foam, perfectly suited for metal casting model construction. These materials offer enhanced thermal and dimensional stability, ensuring repeatable casting results.

3. Versatile Application Areas

Evomatec foam models are used in a wide range of industries and casting methods:

• Foundry model making for aluminum, iron, and steel castings

• Foam pattern casting and lost foam casting processes

• Prototype and serial production models

• CNC rigid foam molds for ceramic and sand casting

• Custom-made models and model repair services

4. Cost-Efficient and Time-Saving Production

The use of Strafor in foundry model making allows for short production times and cost-effective manufacturing. Models can be easily modified, adjusted, or duplicated, making the process ideal for prototyping, small batches, and development projects.

5. Sustainable and Residue-Free Casting

Evomatec’s EPS and rigid foam materials are recyclable and burn out completely during casting, leaving no residue and ensuring a clean, smooth metal surface.
