Maintain a minimum draft angle of 1° per side.
4 Therma-Tech
Incomplete Fill
Melt and/or mold
too cold
• Increase nozzle and barrel temperatures
• Increase pack and hold pressure
• Increase nozzle tip diameter
• Check thermocouples and heater bands
Mold design
• Enlarge or widen vents and increase number of vents
• Check that vents are unplugged

The reliable low liquid level
detection system alerts operators when product
is running low; adding additional product does
not require stopping the machine, so continuous
production is possible without any loss of part color.
