Why does the mold appear oily?

The silicone itself does not emit oil. Oiliness is caused by adding composite silicone oil (silicone oil mixed with white mineral oil) during operation.

Why does the silicone mold have traces, streaks, and unevenness on the surface?

This happens if the original model is not smooth or polished, or if the release agent was not applied evenly. The mold replicates the imperfections of the original.

What are the wonderful usages of mold silicone?

It is widely used in toy, gift, furniture, character reproduction, building decoration, resin crafts, candle making, plastic toys, gypsum crafts, glass products, and sculpture industries.

Product Q&A

Q:Why can the silicone mold be reused only for a few times?

Common reasons include adding too much silicone oil which destroys molecular weight, adding excessive catalyst (more than 2% for tin cure) which speeds up operation and reduces strength, or using incorrect hardness for the product design.

Q:Why does the silicone mold get burnt out?

This occurs when using unsaturated resin which generates heat during curing. You must demould the product within 3 minutes. Our rubber includes special materials to resist high temperatures.

Q:Why does the silicone mould appear dry outside but wet inside?

This is typical for condensation silicone rubber that absorbs moisture from air. To fix, add 0.05% water and stir briefly at low speed before use.

Q:Why is the tear strength of silicone molds weak?

Weakness is caused by adding too much silicone oil, adding excessive catalyst (recommend no more than 5%, ideally 2%), or using the mold prematurely before 24 hours of curing.

Q:Why does the mold silicone have poor tension?

Adding large amounts of silicone oil to reduce viscosity makes the rubber too soft, resulting in poor tensile strength, short service life, and fewer mold turnovers.
