The silicone rubber mold has few molding times is due to following reasons: adding too much silicone oil which will destroy the molecular of silicone rubber; making the mold for small and fine detailed products with higher hardness silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products.
Why does the silicone rubber mold have few molding times?
5) Frequently asked questions of molding silicone rubber
.
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.
3. Adding curing agent 3%, the silicone rubber can still be operated within 28 - 30 minutes and can be demoulded after 1.5-2 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.
1. Adding curing agent 1%, the silicone rubber can still be operated within 2.5 hours and can be demoulded after 6-8 hours.
4)RTV Silicone rubber curing instruction:
.
(Note3: our company does not recommend you to add silicone oil. If a special soft silicon mold or fine detailed and complex patterns products are required, 5%-10% silicone oil can be added to soften the mold for easy demould.)
Note 2: If the customer wants to make large products and large size molds, the mold should be made of silicon rubber with high hardness. On the contrary, if the mold with fine and precision patterns, it should be made of silicon with low hardness. The amount of the curing agent depends on the actual requirements of the customer. If molds requiring fast drying and demould, more curing agent is needed; contrarily, if molds requiring slower drying and demold, less curing agent is needed.
at last brush evenly with a wooden plate or a brush, and fill up the mold frame with gypsum after the silicone rubber is dried.
thirdly mix the silicone rubber and the curing agent evenly according to the mixing ratio of 100 : 2 and pour them onto the sole model,
then enclose the plane frame with wooden plates to prevent the leakage of the silicon rubber,
firstly fix the product or sole model to be duplicated onto a plane plate,
Note1: RTV-2 silicone rubber is used for pouring or brushing technique. That is to say,
c. After deaired, pouring the liquid silicone rubber into the product to be duplicated or into the mold frame.
b. After the silicone rubber and the curing agent are completely mixed, put the silicon into a vacuum machine for deairing to remove the bubbles.
a. take silicone rubber of 100g and add 2% curing agent for mixing evenly.
Steps:
RTV silicone rubber is composed of two components. Component A is white flowing liquid while component B is the curing agent.
3) Operations of RTV Silicone rubber for mold making
.
RTV Silicone rubber for mold making is white or red flowing liquid with general hardness of 22-50A
This silicone rubber is the one with the highest use level in the production of artwork and the shrinkage less than 0.2%
