These calculations produce guide values; the final selection has to be based on the part geometry, the mold design and the data from the material manufacturer. For an assessment specific to your application, contact our technical support team.
An STL file describes the surface of the part with triangles. From a closed surface the volume is calculated exactly; volume x density gives the weight, and the silhouette projection perpendicular to the mold opening direction gives the area that the clamping force calculation is built on. Unlike a photograph, nothing is estimated from a 3D file — the dimensions are read from the geometry itself.
The file is processed entirely in your browser; because it is never uploaded to a server, confidential part geometries can be analyzed safely. Wall thickness is not extracted automatically — enter the thickest wall by hand for the cooling calculation.
The method, the formula and the limits of each tool are explained directly underneath it, and the explanation changes with the tab you select. The results are engineering guide values; for an assessment specific to your application when choosing the final machine and equipment, contact our technical team.
