Urethane casting also called vacuum casting and polyurethane casting, this process need make a master model by CNC or 3d printing process, then use this master model to make a silicone mold which use it to copy more same parts, It is a low cost way for making low volume plastic parts.

The Difference Between Urethane Casting What is CNC machining and urethane casting? CNC is mean “Computer Numerical Control”. CNC machining is a technology that machined the parts by removing layers of the material to shape the parts’ structure. The price of custom cnc machining is higher than urethane casting if machined same parts, because CNC process charge by CNC processing time, but vacuum casting process, one silicone mold can be make 10-15 high quality production, so for plastic parts small batches production, the cost- effective of the vacuum casting process is more better than CNC. • CNC Machining And • • • https://e-make.co/cnc-machining/
Differences: 1) The way of machining. CNC precision machining is making the parts one by one via CNC machine. Urethane casting is making a mould according the original parts firstly, and then duplicate parts by the mould. 2) The materials. All kind of engineering grade plastic and metal sheet or rob material can be processing by CNC machined, its material selectivity is big. But only the plastic parts can be made by urethane casting. Also, Urethane casting is using the mixed plastic, not the pure plastic.Such as similar ABS, not pure ABS. 3) The processing time. Generally, if low volume production, CNC machining will be taking more time than urethane casting. 4) The precision. 5) About the strength : The strength of CNC parts is good then urethane casting parts because cnc prototyping services material is engineering grade plastic and metal material. 6) The price. https://e-make.co/metal-cnc/
Advantages of CNC Machining A) AVAILABLE METAL MATERIAL Commonly used production-grade metal materials, such as: Aluminium alloys, aluminum magnesium alloys, zinc alloys, titanium alloys, brass, stainless steel, Mild steel, Invar, copper and so on. B) SURFACE FINISHING: The parts from CNC process have a tool marks with rough, we also can provide additional finishing services according to your needs like polishing, mirror polishing, anodizing, plating, sandblasting, Passivating, Blacking, Painting, silk-screen, laser engraving and powder coating and so on. C) COLORS: We can match any color on your CNC machined parts according to your specification if you can provide us a color sample or Pantone color number. https://e-make.co/cnc-machining/
