FAQ

What types of products and industries is the ONGO N series N250 best suited for?

The N250 is a 250‑ton class injection molding machine designed for medium‑to‑large parts. Typical applications include automotive interior and exterior components (dash panels, bumpers trim), appliance housings, large consumer goods (containers, crates), industrial enclosures and fittings, and larger medical or laboratory components. Its capacity makes it well suited where larger shot volumes and stronger clamping force are required.

What plastics and part sizes can the N250 process reliably?

The N250 can process a wide range of thermoplastics used in industrial production: PP, PE, ABS, PS, PC, PA (nylon), PBT, filled and glass‑reinforced grades, and many engineering resins. Exact maximum shot volume and screw diameter depend on the machine’s barrel/screw configuration and options; commonly configured for medium to large shot sizes that produce parts from tens of grams to several kilograms. For precise limits (shot size, max mold area, platen opening), consult the machine datasheet or supplier.

What mold designs and features are recommended when using the N250?

Mold design should match the machine’s platen dimensions, tie‑bar spacing and clamping force. The N250 supports molds with hot runner systems, valve gates, slide or lifter mechanisms, and heavy mold bases when properly supported. Consider mold weight and height relative to the platen tonnage and mold tilt/removal method. Multi‑cavity layouts are feasible for smaller parts; larger single‑cavity molds are common for big parts. Coordinate ejection strokes, runner systems and gating to optimize cycle time and part quality.

Is the N250 suitable for automated and high‑volume production lines?

Yes. The N250 is commonly integrated into automated production lines with part pickers/robots, conveyors, vision inspection, and secondary operations. It performs well in long production runs where consistent cycle times and stable process control are required. For high throughput, optimize cooling channels, cycle time, screw/barrel specification and automation for part handling. Energy‑saving options and servo hydraulics (if equipped) can improve long‑run efficiency.

What are the typical installation and utility requirements and safety considerations?

Installation needs vary by configuration but generally include sufficient factory floor area with level foundation, electrical power per the machine’s rating, compressed air for controls and ejectors, hydraulic connections if needed, and cooling water or chilled water for temperature control. Ensure proper access for mold changes and robot installation. Safety: fit guarding, light curtains or area scanners for automation, emergency stops, and lockout/tagout procedures. Train operators on safe mold change, maintenance and machine controls.

What routine maintenance and common troubleshooting issues should operators expect?

Routine tasks: daily checks of hydraulic oil level and temperature, mold and platen cleanliness, barrel temperature stability, screw/barrel wear inspection, lubrication points, and filter condition. Weekly/monthly preventive tasks per the manual include oil and filter replacements, verifying unit calibration, and safety interlocks. Common issues: flash (reduce injection pressure or improve venting), short shots (adjust melt temp, back pressure, or shot size), burn marks (lower melt temps or increase shot speed control), unstable cycle times (check cooling efficiency and heater zones). For persistent faults or complex hydraulic/electrical issues, contact certified service technicians and follow the manufacturer’s troubleshooting guide.
