PET bottle embryo injection common problems and solutions
Hello, everyone, today we will talk about some common problems that may be encountered in the process of PET bottle embryo injection molding and corresponding solutions. As a professional mold manufacturer, Heyan Mold also has some practical suggestions for these problems.
Problem 1: The bottom of the PET bottle embryo is white
Reason: May be insufficient drying or uneven cooling of raw materials.
The solution:
Ensure that the raw material is dried for more than 4 hours and the moisture content is less than 0.02%.
Strengthen cooling, adjust the distribution of cooling water to ensure uniform cooling.
Problem 2: The PET bottle embryo is not transparent
Reason: May be insufficient material temperature or insufficient cooling.
The solution:
Raise the feed temperature and screw speed to ensure that the raw material is fully plasticized.
Strengthen cooling, especially on the bottom and walls of the embryo.
Problem 3: PET bottle embryo from transparent to opaque
Cause: It may be that the holding pressure is too high or the cooling is not uniform.
The solution:
Appropriately reduce the holding pressure.
Adjust cooling water distribution to ensure even cooling.
Problem 4: There is fog shadow on the side of PET bottle embryo
Cause: May be mold problems or improper injection speed.
The solution:
Check the mold to make sure the gate holes are positioned correctly and without eccentricity.
Adjust injection speed to ensure even filling.
Problem 5: PET bottle embryo has silver lines or yellow
Cause: Plastic decomposition or excessive temperature.
The solution:
Reduce drying temperature and material temperature to avoid plastic decomposition.
Strengthen raw material drying to ensure low moisture content.
Problem 6: There are bubbles in the PET bottle embryo
Reason: It may be that the raw material is not dry enough or the screw speed is too high.
The solution:
Strengthen raw material drying to ensure low moisture content.
Reduce screw speed to avoid excessive shear.
Problem 7: There are irregular ring grooves in the PET bottle embryo
Cause: It may be improper mold design or injection conditions.
The solution:
Check the mold design to ensure that the hot runner is concentric with the gate.
Adjust injection conditions, such as injection pressure, injection speed, etc.
Problem 8: PET bottle embryo is torn at the gate
Reason: May be mold design or improper cooling conditions.
The solution:
Correct mold design to make sure gate position is correct.
Extend the cooling time to ensure that the embryo is sufficiently cooled.
These are some common problems and solutions that may be encountered during the injection molding process of PET bottle embryos. If you have any questions or need more professional advice, please contact us, we will be happy to serve you! Remember to like and follow oh! 🔥 🔥 🔥
