WHY THIS PAGE EXISTS

Why Some Mold Designs Need Softer Tin Cure Silicone

Not every mold should start with a firmer grade.

If your part has delicate edges, deeper undercuts, or shapes that are more difficult to remove cleanly, a softer silicone can help the mold release with less stress during demolding.

That often means fewer damaged edges, more practical mold handling, and a better first trial for detailed designs.

Detailed molds with undercuts
Soft silicone helps easier demolding when the casting has fine details, fragile patterns or complex shapes.
Not recommended forLarge molds, heavy castings, thin-wall molds that need strong shape support, or applications where dimensional stability is more important than easy release.For large or heavy molds, a higher Shore A grade with better shape support is usually recommended.
Typical Shore AShore A 5 / 10 / 15 /20Shore A 5–15 is usually better for easier demolding; Shore A 20 is better when more shape support is needed.
Viscosity5000/8000/11000 mPa.sLower viscosity is better for pouring fine details; higher viscosity can be selected when more body or less flow is required.

Recommended Soft Grades

TC-05

Best when maximum softness and flexible release matter most.

TC-10

A practical soft-grade option for easier demolding and better daily handling.

TC-15

 A softer choice with slightly more body for buyers who still want easier release.

Not sure which one fits better?

We can recommend the right starting grade based on your mold size, shape complexity, and casting material.

What Buyers Usually Want to Improve

Easier peel-off behavior

 A softer mold usually releases more naturally from more complex shapes.

Less demolding stress

Helpful when the mold design includes detail that is easy to pull or damage.

Better flexibility for undercuts

A softer body can work better where the mold needs to stretch slightly during release.

A safer choice for small detailed molds

Often more practical for candles, soaps, crafts, and decorative resin parts.

APPLICATIONS

Best-Fit Applications

These applications demand high detail, flexibility, and reliable demolding performance. Proper silicone selection ensures consistent results and longer mold life.

FAQs

Is softer tin cure silicone better for deep undercuts?

Often yes. A softer mold usually releases more easily from shapes that need more flexibility during demolding.

Will a soft grade always last longer?

 Not necessarily. Easier release helps some designs, but mold life also depends on wall thickness, handling, and casting conditions.

Is this the right choice for large concrete molds?

Usually not the best first choice. Larger molds often need more support.
