Why does the mold appear oily?

The mold itself does not emit oil. The oil is caused by adding composite silicone oil containing 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 is not applied evenly.

What are the wonderful usages of mold silicone?

It is widely used in toy, gift, furniture, character reproduction, building decoration, resin handicraft, candle craft, plastic toy, 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 reduces molecular weight, adding excessive catalyst (more than 2% for condensation cure), or using the wrong hardness for the product size and design.

Q:Why does the silicone mold get burnt out?

This occurs when using unsaturated resin without demolding within 3 minutes, as the resin generates great heat during curing. Our rubber includes special materials to resist high temperatures.

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

This is due to moisture absorption from the air during solidification. To fix this, add 0.05% water to the silicone rubber and stir briefly at low speed before use.

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

Weak tear strength is caused by adding too much silicone oil, using excessive catalyst (over 5%), or using the mold prematurely before the recommended 24-hour curing period.

Q:Why does the mold silicone have poor tension?

Poor tensile strength results from adding large amounts of silicone oil to reduce viscosity, which makes the rubber too soft and reduces durability.
