Pinch Points
Do not place weights in precarious positions where they can be bumped and fall to the floor. For
large test weights (over 10 kg) the pneumatic lift system is recommended. The lift system
has a mechanical capture rod which wi
ll not allow the weights to “fall” out of the machine. When
the machine is in operation the lift system moves the weight downward somewhat quickly
creating an area where anything lying beneath could be crushed. The lift system has a safety
door that, when installed correctly and not tampered with, will prevent the lift from moving when
open. There are redundant internal firmware and mechanical hardware safeties in place in the lift
system.
Fumes from Materials
Please plan for unexpected issues to arise. Many polymers (PVC, PVF etc.) are well known for
giving off hazardous fumes at elevated temperatures. An exhaust system that removes fumes
from both the die exit and near the top of the barrel is strongly recommended. Consideration
should also be given to additives that may degrade or decompose at elevated test temperatures.
