Contamination Control in Thermoforming
Sheet materials need to be free of contamination and plastic swarf prior to entry to the thermoforming machine. Failure to manage material cleanliness will result in inclusions embedded in the finished product.
Large sheets can be cleaned using a Meech JetStream Ionising Air Knife System, while smaller sheets could use a Meech 957 air curtain or Meech 954 ionising gun. Charges generated during thermoforming may result in further contamination or operator shocks during handling.
