Safety Hazards Some common safety hazards associated with injection molding equipment are: • • • • • • • • •

2.3.1

Mechanical (pinching, shearing, crushing) High Pressure Leak Burn Explosion Electrical Noise Gas, Vapor and Dust Emissions Slip, Trip or Fall Lifting

Mechanical Hazards •

Worn Hoses and Safety Restraints Regularly inspect and replace all flexible hose assemblies and restraints.

•

Cooling Water Hoses Cooling water hoses degrade over time and need to be replaced on a yearly basis. Cooling water hoses routed in the vicinity of the barrel are exposed to high temperatures that shorten their useful life and can require more frequent replacement. Degraded hoses become brittle and can break or separate from the fitting when manipulated. To minimize the risk of failure, inspect the hoses regularly and replace as required. Make sure to wait until the machine has cooled down before servicing cooling water hoses.

•

Stopping the Machine

Stopping the Machine The machine is considered stopped when all motions stop and all stored energy is discharged. The machine is not considered stopped if one of these conditions is not met. For example, the machine is not considered stopped if the operator opens a safety gate. The safety gate interlocks will only stop machine motions, not de-energize the machine. This chapter describes three different ways to stop the machine: • • •

Stopping the machine in an emergency Pausing the machine Stopping the machine in a controlled manner

This chapter also discusses unexpected machine stoppages.


6.1

Stopping the Machine in an Emergency The emergency stop button allows the operator to quickly stop the machine in an emergency. All machine motions will stop, the pump motor(s) will stop, and the hydraulic system pressure will be discharged when the emergency stop button is pressed.

CAUTION! Mechanical or electrical hazard – risk of damage to the machine. When powering down the machine in non-emergency situations, do not use the emergency stop buttons. Use the method described in Section 6.3 to avoid damaging the machine.
