3D MID Blog: LDS vs. 2-Shot (www.selectconnecttech.com) The biggest advantage of LDS over 2-shot is the separation of the processes and therefore electrical comes in much later in the design phase. In 2 shot molding the electrical design is tied to the mold itself. Once the mold done you can’t change anything unless you change to a different mold. But with LDS the standard molding of the part doesn’t effect the circuit structure. The circuit structure is added to the part later on. We can move the design phase of the electrical to much later in the process and therefore really fine tune the part. You can even take it a step further and mitigate problems or tolerances we see in the molding that we couldn’t anticipate at the start. So we can actually adjust the electrical design to the mechanical and compensate for unforeseen issues.

MYOS test machine used for 2nd shot, a TPE overmolded onto a polypropylene first shot. This set-up was for low volume prototype parts that needed to be tooled and molded FAST. The machine does demonstrate the MYOS molding technology and that means low power consumption and high efficiency. The efficiency means that we deliver 95% of the pressure generated into the mold cavity.
