In order to correct this problem, the amine vapors and air were allowed to enter the core sand mass only around the outside of the tamper pins and through vents in the tamper pins at the blow tube openings.
After reviewing the problem, a decision was made that the blow tube spacing was the potential problem.
between the blow tube centers also is used wherever possible.
In most instances, the blow tube spacing of no more than 5.0 in.
Also, on some occasions, it was not possible to install enough blow tubes due to space constraints in the corebox lid.
Blow tubes were added to the corebox at approximately 5 in.
This change in number of blow tubes and the spacing of the blow tubes eliminated the problem with cope stickers as well as the depressions under the cope vents.
The T series is "tubeless," as the name suggests (utilizing bits without plastic Blow Tubes), and achieves the goal of using industry bit shank connections, but without the plastic component imbedded in the bit.
Maintain is simply the idea that maintaining corebox seals, blow tubes and regular cleaning of the core vents can ultimately increase production and the quality of the finished cores.
