FAQs
-
Why does silicone fluidity matter during mold making?
-
Good fluidity helps silicone reach corners, texture lines and narrow details around the master model. Better flow can reduce missing detail in the mold cavity.
-
How can bubbles be reduced in silicone molds?
-
Slow mixing, controlled pouring, proper resting time and vacuum degassing can reduce bubbles. Model shape and silicone viscosity also affect trapped air.
-
What affects the service life of a silicone mold?
-
Mold life depends on silicone tear strength, casting material, demolding method, mold storage and how often the mold handles deep undercuts or sharp edges.
-
How should silicone hardness be selected?
-
Softer silicone suits complex shapes and easier release. Firmer silicone gives better support for larger molds or pieces that need stronger shape retention.
-
Can one silicone mold work with different casting materials?
-
Many silicone molds can work with resin, gypsum and wax, but compatibility depends on curing heat, material adhesion and release requirements.
-
Why do silicone molds sometimes tear during demolding?
-
Tearing may come from low tear strength, thin mold walls, sharp model details, aggressive pulling or insufficient release design around undercuts.
