How many times can a silicone mold be reused?

Reuse frequency depends on usage. Avoid adding too much silicone oil or catalyst, and use appropriate hardness for the product size to extend mold life.

What is the lead time for mass production?

Mass production orders are normally shipped within 3-7 days after receiving payment.

Is the silicone rubber food grade?

Yes, this platinum cured silicone rubber is food grade and can completely replace condensation (tin cure) silicone rubber for food applications.

It also states production capacity above 500 tons per month, indicating substantial manufacturing capability.

Product Q&A

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

Weak tear strength is often caused by adding too much silicone oil or catalyst. We recommend adding no more than 5% catalyst (2% is ideal) and avoiding excessive silicone oil to maintain integrity.

Q:Why does the silicone mold get burnt out?

Burnt out occurs when using unsaturated resin without proper temperature control. The resin generates heat during curing; you must demold the product within 3 minutes to avoid damage.

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

This happens because molding silicone absorbs moisture from the air. To fix this, add 0.05% water to the silicone rubber and stir briefly at low speed before use.

Q:Why does the mold appear oily?

The mold itself does not emit oil. Oiliness is caused by adding composite silicone oil (mixed with white mineral oil) during operation, as white mineral oil is a petrochemical product.

Q:Why does the mold have traces or unevenness?

Unevenness usually results from an unpolished original model or uneven application of release agent. Ensure the model is smooth and the release agent is brushed evenly.
