Making the mould

for making the negative mould i use the wax material i use the modela machine for making the negative mould .for this i save my solid works design file in .png then i import the file in the modela and make rml.then i select the offset,and end mill as 1/8".and send for milling the wax material as per my design.


this is the image while milling


for this i use the same process of milling the pcb only the bit change


The process of making negative mould is over now its time to make positive mould from this mould for that i use the rubber material .I choose rubber material because the casting material easily come out from this.to remove the bubble i use the injection in this process


The rubber material is expiered thats why it takes 2 day for dry ,but after 2 days my positive mould is ready
