Product Description

 

Product Description

Features and benefits:

Silicone is ideal for making reusable molds. The extremely stable, yet flexible material can be used particularly well in mould and model making. Thanks to the beneficial properties of silicone rubber, even complex objects with multi-dimensional undercuts are perfectly reproducible with great attention to detail.

Popular Applications:

• Model and mould making.
• Prototyping and industrial applications.
• Food impressions.
• Candle and soap mould.
• Plaster and concrete casting.
• Casting
• 

Do it yourself! Make your own silicone moulds and models.

Silicone molds can be made quickly and easily by yourself. The liquid silicone consisting of two components is mixed in the specified mixing ratio and then poured into the intended shape over the object to be duplicated. After curing, the mould can then be poured out with the appropriate casting compound.

Installation Instructions

1.Enclose the product (the original model) with four plastic plates or wooden plates

2.Clean your products and brush a layer of release agent (detergent or soap water) on your product.

3.Stir part A 100g and part B 100g with 1:1 mixing ratio evenly. And get the mixture for vacuum-pumping. (If there is no vacuum machine, you can just pour the mixture slowly from the corner so that less bubbles caused)

4.Pour the mixture with correct mixing ratio into the model frame. After about 2-4 hours, when the silicone cured, get out the original model, and there you get a finished addition cured silicone mold.

Company Profile

FAQ

1. What's silicone products you are making?
--liquid silicone, silicone rubber, silicone oil; Due to different silicone molds, our silicone has different viscosity, and cause different hardness, density to meet the requests from client.  

2. Do you offer free sample to client?
--Yes, we can provide the sample for test.  

3. How about the quality control in your factory?
--We have professional QC team to control the quality during production. Goods will be 100% inspected before shipment.  

4. How to remove the bubbles during my mould making?
--After mixing liquid silicone with curing agent, please put the material into vacuum machine to take off the bubbles.  

5. How to get good silicone mould to use longer time?
--The best way is:   #A, Please choose the right liquid silicone according to your products.   #B, Don't use any silicone oil in mold making, because it can make the silicone mould become too soft to use.   #C, Silicone mould can be used longer after the whole silicone mould fully cured, so it's better to wait 2 hours after mould finished.  

6. Why silicone rubber add curing agent after mixing a lot of bubbles?  
--This is normal physical phenomena. The liquid will produce a large number of bubbles in the mixing time, so, it must pass through the vacuum exhaust bubble treatment.
