How is the model created?

The final model is created by machining, i.e. milling a solid on a multi-axis CNC machine, which guarantees high precision manufacturing, as well as perfect reproduction of all dimensions and shapes included in the 3D model. This is made possible by programming the CNC machine tool in CAD / CAM post-processors.

What materials do we use to make models?

The materials we use to make models are:

  • Waterproof plywood – that is, a composite material that consists of thin, crisscrossing layers of wood bonded with waterproof glue;
  • Ebablock resin boards – like plywood, they are characterized by easy machinability, in addition, they are highly resistant to abrasion;
  • Ebazell resin boards – very lightweight and easily machinable material;
  • Prolab polyurethane boards – show high heat resistance and high surface quality after finished processing.

Any number of models in a series

Programming in CAD / CAM and milling on CNC machining centers guarantees perfect repeatability of models. Therefore, you can place an order for both large and smaller series without any worries.

Step one – preparing the 3D model

Using advanced CAD software, we will create an accurate 3D model that takes into account all dimensions and shapes of your final product. CAD design also allows you to take into account the hardness and strength of the material from which the model will be made.

You can provide us with a finished 3D model in a file in .dxf or .dwg formats. If you do not have the ability to make 3D models in these formats, send us accurate technical drawings. Based on them, we will make 3D models in CAD.

Step two – programming the machine in CAM

In order to obtain accurate models during production, we move to the next step, which is programming the CNC machine tool in a CAM post-processor. This process involves transferring the exact dimensions and shapes of the 3D model into the paths that the milling tool directed by the machine will take.

Step three – milling of casting models

Subsequently, the lump from which the final model is to be made is machined. In other words – the shape is given by removing excess material. Machine tool movements are extremely precise, so that even the smallest details related to dimensions and shapes are reproduced on the physical model.

We are able to make models of considerable dimensions, as the maximum working area supported by our machine tools is 1.3×2.5m.

FAQ

Answers to frequently asked questions

Casting model milling is a machining process in which specialized milling tools shape the material to create precise casting molds. This is a key stage in manufacturing, as the accuracy and quality of the casting models directly affect the quality of the final castings. Milling makes it possible to create complex shapes with high precision, which is essential in many industries such as automotive, aerospace and engineering.

Materials such as wood, epoxy resins, aluminum and various plastics are most commonly used for milling casting models. The choice of material depends on requirements for strength, accuracy and production costs. Wood is the traditional material used in model casting, while epoxy resins and aluminum are preferred for their durability and ability to accurately reproduce details.

High precision: makes it possible to create models with accuracy to hundredths of a millimeter.

Speed and efficiency: automation of the process allows rapid production of models even with complex shapes.

Flexibility: the ability to machine a variety of materials, allowing customization to meet specific project needs.

Surface quality: milling provides smooth surfaces, which minimizes the need for additional machining.

The milling process for casting models uses advanced CNC machines that are computer-controlled. These machines are equipped with a variety of cutting tools that can be quickly and precisely changed during operation. Technologies such as CAD and CAM are integral to the process, enabling the design and programming of toolpaths to ensure high accuracy and repeatability in model production.
