FAQ Troubleshooting for Rotational Moulding

  1. Q : Resin selection not correct

    A :Use a lower density or lower meltl index

  2. Q : Density increase during slow cooling

    A : Increase the cooling rate to maintain lower density

  3. Q : Part not designed properly

    A : - Review and alter mold design if necessary
    - Eliminate sharp corners and narrow passage

  4. Q : Insufficient fusion of resin powder

    A : Increase temperatue or heating time

  5. Q : Cooling too slow

    A : - Increase water pressure
    - Use spray instead of fog nozzles

  1. Q : Part overcured during molding

    A : Decrease oven temperature or heating cycle

  2. Q : Photodegradation of part caused by UV or fluorescent

    A : Use suitable UV stabilizer

  1. Q : Improper mold rotation

    A : Optimize ratio and speed of the rotating mold to obtain even coverage and adequate number of powder trakinas

  2. Q : Uneven mold wall thickness

    A : Use care in designing molds to prevent excessive variations in mold wall thickness (thin spots attract Imore resin)

  1. Q : Heat transfer rates not adequate to melt all the resin, excessively thick mold

    A : - Increase heat transfer rate by using thinner mold walls
    - Make the mold from material with greater heat transfer coefficient (e.g. steel, aluminum, copper)

  2. Q : Heating not efficient

    A : Increase air velocity around mold during heating cycle

  3. Q : Poor flow

    A : Use higher melt index resin

  4. Q : Oven temperature too low

    A : - Increase oven temperature
    - Increase air circulation in oven
    - Use lower density powder

  1. Q : Insufficient amount of release agent

    A : Use more release agent

  2. Q : Roughness and porosity of mold surface

    A : Refinish damaged mold surface

  3. Q : Shrinking onto large deep inserted areas

    A : - Use very effective mold release on insert area
    - Remove part while warm

  4. Q : Degradation of plastic

    A : Reduce oven temperature or time slightly

  5. Q : Incomplete shrinkage due to molding being hot

    A : Increase cooling cycle

  1. Q : Oven temperature not high enough to drive air bubbles out of the part walls

    A : Increase oven temperature or total heating cycle

  2. Q : Heat transfer rates not adequate to melt all the resin

    A : - Increase heat transfer rates by using thinner mold walls
    - Make the mold from material with greater heat transfer coefficient (e.g. steel, aluminum, copper)
