v 2.6 — April 2012 HyPET Injection Molding Machine
8 Safety Hazards
• Do not operate the machine if scheduled preventive maintenance has not been
performed.
• Do not use a magnetic platen without approval from Husky and the magnetic platen
supplier/manufacturer.
2.3 Safety Hazards
Some common safety hazards associated with injection molding equipment are:
• Mechanical (pinching, shearing, crushing)
• High Pressure Leak
• Burn
• Explosion
• Electrical
• Noise
• Gas, Vapor and Dust Emissions
• Slip, Trip or Fall
• Lifting
2.3.1 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.
• Injection and Clamp Units
Hydraulic circuits in injection and clamp units contain high pressure accumulators.
Before servicing hydraulic systems, lock out and tag the machine to discharge all stored
energy. When servicing hydraulic systems, read the equipment manuals and refer to
hydraulic schematics for additional details.
