Processing method

 

1. Mix part A and pars B evenly with 1:1 mixing ratio.

Notes: 1) Weigh the two parts exactly by electronic weight. For example, the operation time will be shorten after adding too much catalyst.

1. Mix part A and part B evenly. Otherwise the silicon rubber will be partly solidified which will make the finished molds meet a short life and

waste silicon rubber.
 

1. Vacuum pumping

Notes: 1) This step is not have to have, but it is best if there is one. It will discharge all air in the mixture  successfully, so as to ensure that there
will be no bubbles in the finished mold.

2) This step is less than 10 minutes. Otherwise, it
Will cause cross-linking reaction, and no more
further steps will be available.
 

1. Pouring casting or Brush molding

Notes:1) For simple pattern products we suggest use pouring operation way, which will be very easy to operate and demould. Pourable silicone require low viscosity which will be easy to flow smoothly and easy to de-air.

1. For delicate pattern products we suggest use brushing operation way, which can copy the pattern exactly. Brushable silicone require high viscosity which won't be easy to flow away and easy to brush.      
2. We suggest to set the mold for another 12 hours after demould before put it into large production.
