silicone rubber stone molds made from liquid silicone

1. Application for silicone rubber stone molds made from liquid silicone

Liquid Silicone Rubber is primarily intended for poly resin crafts, PU crafts, stone nolds, gypsum crafts, unsaturated resin crafts, lighting and candles crafts, plastic toy, stationery gifts crafts industry, a large statue Buddha, relievo furniture, furniture decorative materials, statues Buddha, artifacts copied, building decoration materials, large-scale cement mold, artificial fossils Factory, Europe component factory, simulation landscapes, animals and plants sculpture, sandstone crafts and so on.

2. Instruction for silicone rubber stone molds made from liquid silicone

Add curing agent of 2%-3% at the room temperature, the silicone rubber is still operational within 30 minutes, and in 2-3 hours.

1. Adding curing agent 1%, the silicone rubber can still be operated within 2.5 hours and can be Demoulded after 6-8 hours.

2. Adding curing agent 2%, the silicone rubber can still be operated within 50 minutes to 1 hour and can Be demoulded after 2-3 hours.

3. Adding curing agent 3%, the silicone rubber can still be operated within 28 - 30 minutes and can bedemoulded after 1.5-2 hours.

4. Adding curing agent 4%, the silicone rubber can still be operated within 10 - 15 minutes and can be demoulded after 1 -1.5 hours.

4.Operation steps of silicone rubber stone molds made from liquid silicone

Step One: Take 100g of part A and add 2g of part B and mix the silicone rubber and curing agent evenly.

Notes: Moulding silicon rubber is a kind of flowing liquid and it contains two parts. Part A is a kind of white flowing liquid and part B is the curing agent.

Step Two: vacuum pumping

Without exception, this step takes less than 10 minutes.

Note: The time for vacuum-pumping should be less than 3—5 mins , otherwise, once the silicone rubber has cross-link reaction during vacuumizing, it will not be operated.

Step Three: Brushing cast & Perfusion Molding operation

5.FAQ of silicone rubber stone molds made from liquid silicone

Why could the silicone mold be reused only for a few times?

It can be due to the following reasons:

a. Adding too much silicone oil in to silicon rubber. Silicon oil is an additive which destroies the molecular weight of silicone rubber and reduce the tension and tear strength.

b. Using the silicon rubber with a high hardness to make molds for small sized products with delicate and intricate designs and the silicon rubber with a low hardness to makes molds for large sized products with simple designs.

(Notes: we should choose the silicon rubber specifically according to the requirements of our products to avoid this problem.)

5.Certifications of silicone rubber stone molds made from liquid silicone

7.Our factory:

Need the price or other information for reference,please help us confirm some question first

1) How about the size of your products?

2) Will you make the silicone mold by pouring way or brushing way ?

3) What's the raw material of your products ? Plaster? resin or other?

Then we will according it to recommend the most suitable RTV silicone with the best price for your reference.
