Common problems with pellet machines include unstable feeding, poor melting, uneven pellet size, die blockage, screen clogging, excessive moisture, weak cutting, high motor load, material degradation, smoke, odor, unstable output, and abnormal noise.

Acetone can melt, soften, swell, crack, or damage some plastics, but it does not affect every plastic in the same way. The result depends on the plastic type, exposure time, acetone concentration, temperature, surface stress, and whether the part is coated, printed, or blended with additives.

Composite railings may look like plastic because they often contain polymer materials on the surface or throughout the structure.
