Mold Tooling Pre-Run Inspection

Pre-run inspection for injection mold tooling focused on cooling lines, clamps, water leaks, ejectors, and general readiness before production start.

Mold Identification and Setup

• Mold ID matches the production order and setup sheet
• Mold is fully seated and aligned in the press
• All locating rings, dowels, and support points are engaged
• Mold surfaces are clean and free of debris, rust, and residue

Cooling Lines and Water Connections

• Cooling lines are connected to the correct inlets and outlets
• Hoses and fittings are secure with no kinks, abrasion, or strain
• No visible water leaks at mold, hose, manifold, or quick-connect points
• Cooling flow is established and within the expected operating range

Clamps, Fasteners, and Hardware

• All clamps are installed, tight, and properly positioned
• Bolts, screws, and retaining hardware are present and secure
• No loose hardware, missing fasteners, or visible damage is present
• Clamp area is clear of obstructions and pinch hazards

Ejector System

• Ejector pins, plates, and return mechanisms move freely without binding
• Ejector stroke and return position are correct for the setup
• No visible damage, galling, or excessive wear on ejector components
• Ejector safety interlocks and machine settings are confirmed per setup sheet

Final Pre-Run Readiness

• All identified deficiencies have been corrected or escalated
• Work area is clear, dry, and free of trip or slip hazards
• Machine, mold, and startup parameters are approved for production start
• Inspector sign-off completed
