The Lifecasting silicone rubber is also called body double silicone rubber. It is a kind of two-components RTV silicone rubber. With platinum cured, it is environmental friendly, skin safe, odorless and nontoxic. Also, it have soft hardness and excellent tension and tear strength and resilience.

for dolls/toys making, such as robot body, sex dolls, baby dolls, silicone pets, artificial animals ect.
For adult products such as penis, vibrator, masturbation cup etc.

* Platinum-based, Medical-grade silicone       (environmental,odorless and nontoxic)
 * Mixing ratio 1:1, easy for machine/manual operation
* High temperature resistance (-60℃-250℃)
* Excellent tear and tensile strength
* High resistance to aging and high duplication times
* Skin touch safety
* Softer hardness

Step 1: Prepare and clean the prototype.
Step 2: Mixing part A and part B of our silicone rubber evenly according to the mixing ratio of 1:1 or 10:1.
Step 3: After mixed the silicone evenly, it is better to release the bubble by vacuum pumping.
Step 4: Pouring cast

Notes: Please finishes all the steps within the operation time. If not, it will cause cross linking reaction, and no more further steps will be available. So, we have to pay attention to the pot life and curing time.

1.How to choose hardness for lifecasting silicone rubber?
When the life casting silicone rubber is applied to different parts of human, it requires different hardness.

To make the thin skin, the hardness is 20 to 25 shore A.

To make the breast, the hardness will be 5 shore A.

To make a complete finger, the hardness will be 8 to 10 shore A. If just to make a layer of skin, the hardness should be 20shore A.

To make the female sex toys, the silicone rubber must be very soft. For example, the silicone bra needs silicone with 3 to 5shore A, 0 shore A is required for especial.

To make the dildo, the hardness of inside should be 20shoreA,surface will be 0 shore A.

To make the vaginal or sex doll , the hardness should be less 0 shore A

To make the silicone mask, the hardness is 40 shore A.

To make the human model, which is filler inside and silicone outside, the hardness of silicone on the surface is 3 to 5 shore A.

To make the artificial limbs, the hardness will be 10 to 15 shore A.

Note: The special hardness should be confirmed with the customer and then recommend the suitable hardness.

2.Why does the silicone mold appear to dry outside but wet inside?
Some molding silicone rubber is a kind of condensation cure silicone rubber, which would get solidified after absorbing moisture. While in order to provide a significant shelf-life for the silicon rubber, we will dry out the water in the silicon rubber. So when the humidness is lower than 50%, this would happen.

Solution: Add 0.1% water into the silicon rubber and Stir over a low speed briefly when you use it. 

3.Why the silicone mould turns to be sticky?
The main reason for this problem is that we do not handle the products or original molds well.
We should deal with the mother mould carefully before molding. Such as for the products with a complicated
pattern or a unsmoothed surface, we should polish and clean the products, then spray the release agent. Normally, the release agent can be Vaseline, detergent. liquid wax Etc. In practical process, you can brush different release agent according to different material.

The second reason is that the operator pour the silicone into the mold when the mixture is not mixed evenly, so the finished silicone mold will not cured and dried entirely.
