Pogo pins insert molding also belongs to metal insert molding. The pogo pins are first put into the mold by hand. Once the mold is closed, plastic particles are melted in the barrel and then injected into the mold, with the plastic flowing around the pogo pins. After the plastic has cooled and solidified, the finished product is removed from the mold, with the pogo pins securely attached to the plastic.
The pogo pins are added to injection molded parts, which reduces the secondary assembly operation after forming, resulting in a complete pogo pin connector system.
1. The pogo pin insert molding is required to withstand high pressure and high temperature during the injection molding process without affecting its current.
2. Since insert molding still relies on plastic to maintain the position of the pogo pins, it is important to design the mold to precisely fix the pogo pin.
3. When the part is still inside the closed mold, the shrinkage of plastic begins immediately after the injection molding is completed. Moreover, when the mold is closed, the pogo pins will limit plastic shrinkage.
Therefore, the size and shape of the pogo pins, the shrinkage rate of the plastic, and the engineer's experience must all be taken into account.
