EXAIR commonly works with plastic injection molding
companies. They produce top quality plastic parts from both commodity and
engineering-grade resins for many diverse industries. The customer reached
out to us with a problem. A mold that they were running was having some
issues. The parts were not releasing and ejecting properly, causing the
need to use a mold release, which was slowing down the process by a manual
operation to the process. Also, the parts were seeing push pin marks,
causing cosmetic issues with the parts. The customer wanted to
explore using compressed air to blow the parts free.
Typical
Plastic Injection Mold
Based on the mold size and layout, a pair of 12" Super Air Kniveswas installed. The knives are oriented to blow straight down along
the face of the mold, one knife per part tree. The strong laminar
flow of air hits the parts causing them to release and drop without the use
of release agents. Also, the push pin marks are within normal
standards, eliminating the the cosmetic concerns.
This is just one example of how intelligently using
compressed air can help improve a process. By using air knives for
wide areas or using a 1" Flat Super Air
Nozzle for very small parts, or anywhere in between, we
can help to solve your part ejection issues and make your process run
better, faster, and with higher quality.
