Abstract:silicone molds are the quick way to make molds.the process as follows:prepare original product,make frame and fixed it.then weighing and stir the silicone and catalyst.next pouring the silicone to every parts of mold after de-air by vacuum machine. Finally, remove the frame after silicone was cured completely,and trimming the mold.
Tools and materials:silicone and catalyst,plastic board,electronic scale,caps,sellotape,glass bar,releasing agent,scissor,knife,Hot melt glue guns and Spatter.
①deburred of the original product by knife,Be careful not to damage the surface and parts.
②spray the releasing agent on original product,Pay attention to the deep hole or narrow slot.
①Stick the frame by hot melt glue guns,to prevent the silicone outflow from the gap.
②To increase about 20-40mm according to the size of original product ,so that better for pour the silicone.
①weighing the part A and part B according to the ratio that supplied by the factory.
②2.Please be sure that mixing by weight ,not volume.
①mix the silicone and catalyst according to the weight.
②2.Be sure to Stir evenly,otherwise,will effect the time of duplication.
①de-air by vacuum machine after stir evenly.
②The time about 10mins,because too long time will produce cross linking curing reaction.
①pour the silicone after de-air.
②Pour the silicone over the original products,and pour more silicone about 20-50mm on the top of original products.
①put the frame away ,and waiting for curing.
②The optimal temperature of curing about 20-30℃.
①find the remarks and cut open the molds after curing.
②In order to prevent silicone molds will deion,Please ensure that de-mould without affect by outside force .
①all progress of make molds are complete after trimming.
②Suggestion:please use the silicone mold after 24hrs,to prevent deion.
