How to choose
Choose by geometry and material compatibility before appearance. Compare opening size, undercuts, target quantity and the need for external support. Check internal dimensions and an actual demoulded sample before purchase; external dimensions alone do not describe the finished result.
Product-specific checks
Water ratio, mixing and setting time affect plaster strength and finish. Compare samples made with the same recipe. Packing before adequate drying can cause moisture and surface problems. Check thin projections and corners against the intended demoulding direction.
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.
