Chapter 7 Storage and Shipping
Hot runner surfaces are sensitive to many environmental conditions and require special methods
for storage and shipping to avoid damage.
NOTE:
The storage instructions in Section 7.2 are recommended when shipping the hot runner by air.
NOTE:
The storage instructions in Section 7.3 are recommended when shipping the hot runner overseas.
CAUTION!
Mechanical hazard – risk of damage to the hot runner. Store all hot runners in an air
conditioned environment.
7.1 Corrosion Protection
Humidity, salt in the air, rapid weather changes, and even condensation that forms during
operation can quickly damage an unprotected hot runner.
Use a protective spray that does not contain chlorouorocarbons (CFCs), has good moisture and
oxidation resistance, and is resistant to mild acids and alkaline.
For additional corrosion protection during storage, add a moisture-absorbing silicate bag before
sealing the hot runner in a vacuum polyethylene bag.
WARNING!
Poison hazard – risk of death or serious injury. Before using any corrosion protection
product, always follow the supplier’s recommendations for use and thoroughly review the
Material Safety Data Sheet (MSDS).
7.2 Short Term Storage
Short term storage is intended for periods less than three months and can be done either in the
machine or separately.
