结论：综上，导致胶管发生破损的原因为套胶工序；该工序套管刚热缩完后温度

Conclusion: <br>In summary, the causes leading to damage to the hose set of rubber step; this step after the high temperature heat-shrinkable sleeve immediately, when the product then falls into the tray from the machine, the distance is too high, resulting in the hose guide pin prick hurt. In the aging process of the ambient 85, further shrink hose, stab position further expand the area damaged, defective occurrence is exposed aluminum.

Conclusion:<br>In summary, the cause of the valve breakage is the sleeve process, the process casing just after the heat shrink slower temperature is high, the product from the machine table into the receiver plate, the distance is too high, resulting in the guide needle will be the hose stab. In the 85-degree environment of the aging process, the hose further shrinks, the damaged area of the stab position is further expanded, and the aluminum shell appears to be poor.

Conclusion:<br>To sum up, the reason for the damage of the rubber tube is the rubber sleeve process. The temperature of the process after the heat shrinkage of the sleeve is high. When the product falls into the receiving plate from the machine, the distance is too high, which causes the guide needle to stab the rubber tube. Under the environment of 85 degree aging process, the rubber tube further shrinks, the damaged area of stabbing position further expands, and the aluminum shell is exposed.
