value supporting makers supports, throughout their production journey oluyoruz..Controlling casting bubbles
Bubbles at corners, surfaces or throughout the volume can have different causes. Review mixing air, restricted filling paths and working time separately. Use vacuum or pressure only with compatible materials and equipment instructions; one method will not suit every mixture.
Product-specific checks
Thin strokes, enclosed counters and small serifs complicate filling and release. Check lettering orientation on both the master and the finished part. Complete filling and legibility at the thinnest stroke can matter more than overall letter height.
Application and sample checks
Define finished dimensions, casting material and critical surfaces first. Record production variables and reassess approval whenever the material or master changes; an earlier sample does not automatically validate a revised process.
