  • For machine,Bought a desktop injection molding machine,you can make a diy injection molding machine too.but buy one machine can save much time.and DIY plastic injection molding machine save much cost,need long time. Which is the best choice? Depend on yourself.

  • Design the mold drawing in CAD. There are three software for choosing:Solidwork,Autocad or Proe. I suggest solidwork,it is easy to learn and use.Find the plastic parts which you want to make,measure the size by Vernier caliper.Then get the 3D drawing.

  • Make a steel or alumuim mold by CNC machine or tool kits. If you have tool kits,you can diy injection mold by yourself too.By CNC machine, it will be very fast.But find a metal CNC machine not easy,our city is a industry city,have many machines,your city maybe is a Agriculture or tourist city,more hard to get it.The mold is small,you can make it on a desktop cnc machine.
