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
Check resin compatibility, permitted pour depth and heat generated during curing. Not every resin suits deep pours. Run a small compatibility trial and follow the product's technical and safety documents for mixing, ventilation and personal protection.
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.
