Have you also considered this question: Why do some PET sheet roll become brittle?

There are many reasons for the brittleness of PET flakes, most of which are caused by internal stress. In general, it can be divided into the following causes.

Equipment problems

1. There are dead ends or obstacles in the barrel, which can easily promote the degradation of the molten material.
2. The plasticizing capacity of the machine is too small, and the plastic in the barrel is not plasticized enough, or the plasticizing capacity of the machine is too large, and the plastic is subjected to heat and shear in the barrel for too long, resulting in easy aging of the plastic, thus making the product brittle.
3. The injector is tilted or unbalanced, and the top trunk section is small or unreasonably distributed.

Mold problem

1. If the gate is too small, adjust the gate size or increase the auxiliary gate.
2. If the diversion channel is too small or improperly configured, try to balance reasonably or increase the size of the diversion channel.
3. Abnormal injection cycle caused by bad mold structure.

Raw material level
1. Raw materials mixed with other impurities, or inappropriate or excessive solvents, and other additives.
2. Some plastics, such as PET flakes, are heated under humid conditions and undergo catalytic cracking reaction with water vapor, resulting in higher strain on the part.
3. Too many times of plastic recycling or too high content of recycled material, or too long heating time in the barrel, can promote parts brittle cracking.
4. Bad quality of the plastic itself, such as large molecular weight distribution, too many components with uneven structure such as rigid molecular chains; or contamination caused by other plastics, bad additives, dust impurities, etc.

Technical level

1. Cylinder and nozzle temperature is too low, adjust. If the material is easily degraded, the temperature of the cylinder and nozzle should be increased.
2. Reduce the back pressure and speed of screw preforming to make the material slightly loose and reduce the degradation of plastic due to shear overheating.
3. The mold temperature is too high, it is difficult to release the mold; the mold temperature is too low, the plastic cools prematurely, the fusion is not good, and it is easy to crack, especially for PET sheet and other high melting point plastics.
4. The cavity core should have a proper release slope. When the core is difficult to release, the cavity temperature should be increased and the cooling time should be shortened. When it is difficult to take off the cavity, the cavity temperature should be reduced and the cooling time extended.
5. Minimize the use of metal inserts, such as brittle cold and heat capacity of polystyrene plastic, not to insert injection molding.

Product design problems

1. There are sharp corners, notches or thickness difference between the parts of the product is prone to stress cracking.
2. Product design is too thin or too much hollowing.
