Molding Silicon For Gypsum Products Fabrication
1 Application of Molding silicon for Gypsum products Fabrication :
Molding silicon rubber is suitable for product duplication and molds manufacture such as:
1) toys, gifts
2) decoration, plate engrave
3) human replica, art crafts,
4) resin crafts, unsaturated resin crafts
5) poly resin crafts, candle crafts, plastic crafts
6) stationeries, plaster crafts, Buddhist statue crafts, etc.
2 Features of the Molding Silicon For Gypsum Products Fabrication
a. good characteristics of easy-operation
b.light viscosity and good flowability
c. favorable tension
d. low shrinkage
e. no deformation
f. high temperaure resistance, acid and alkali-resistance and ageing resistance
3 Advantage of Molding Silicon For Gypsum Products Fabrication
Molding silicon rubber has advantage of excelenlt fluidity and good operational performance, an elastic silicone rubber mold will be obtained with resistance to deformation, high-temperature, acid and alkali and expansion, comfortable duplication times and free sample avalibale.
4 Molding silicone rubber for gypsum specifications:
RTV-HY625# good for small size products mould making by pouring way
RTV-HY630# good for middle size products mould making by pouring way or brushing way
6)high reproduction times
7)resistance to deformation and high-temperature, acid-alkali
5 Operations of Molding Silicon For Gypsum Products Fabrication
Molding silicon rubber is a kind of flowing liquid, and it consists of two component, part A is a flowable liquid silicone rubber, part B is the curing agent.
Firstly, after your previous work of dealing with the original model, take some liquid silicone rubber, add 2%~3% cuing agent of the amount of silicon and mix them evenly.
Then after vacuum-pumping the mixture, you can pour it into the mold frame. The silicone mold will cured in 2~3 hours.
6 Notes of Molding silicon rubber for gypsum operations:
The time for vacuum-pumping should be less than 3-5mins, otherwise, once the silicone rubber has cross-link reaction during vacuumizing, it will not be operated.
7 FAQ of Molding Silicon For Gypsum Products Fabrication
Why does the mold made of silicone rubber have an unsmooth surface with tracks and strips on it?
It is due to product or model to be molded should hasn't been sanded or polished . If the mold or product is not sanded or polished, the mold made of whatever quality silicone rubber will not be good and smooth enough since the mold or the product itself is not smooth or perfect. Another case is that uneven brushing of the release agent will also bring about unsmoothness of the mold.
