Although plastic is not the most important component of the pogo pin connector, it will also affect the overall quality of the pogo pin. Today we will analyze the abnormality of the plastic parts of the pogo pin connector:
1. The color of the plastic parts of the pogo pin connector is different, and the color of the faded product is different from the standard color, which is different from the color of the resin; the phenomenon that the color changes after injection molding is discoloration,
1. Coloring error (color powder is wrong)
2. Resin pollution
3. Excessive use of crushed products
4. Injection molding machine pollution
5. Thermalization of resin, etc.
Two, pogo pin connector plastic parts flash (drape / flash)
1. Poor processing of injection molding machine
2. Insufficient capacity of injection molding machine
3. Poor processing conditions
4. Insufficient clamping force
5. The mold is not tightly attached
6. Deformation of the mold
7. The resin flows too well
8. Gas Vent is too large
9. High injection pressure
10. There are foreign objects on the mold surface
3. The plastic parts of the pogo pin connector lack glue and the resin does not fill all the Cavity, and part of the molded product is insufficient after cooling and solidification.
1. Improper adjustment of feed: A lack of material B more material
2. Improper injection pressure
3. The amount of material is too low
4. The mold temperature is low or the temperature distribution is unreasonable
5. The plastic material has high fluidity
6. Poor nozzle fit
7. Plastic frit blocks the feeding channel
8. Nozzle cold material into the mold
9. The mold design is unreasonable
10. The mold gating system is defective
