FAQ

What kinds of products and production volumes is the ONGO N series N308 best suited for?

The N308 is a mid‑range machine in the ONGO N series designed for small to medium parts and medium-volume production. Typical applications include household goods, consumer electronics housings, automotive interior components, medical disposables (non-implant), packaging caps and closures, and cosmetic containers. It performs well with single- and multi-cavity molds and can support both prototyping runs and continuous production where cycle times are moderate to fast.

Which plastic materials and part geometries work well on the N308?

The N308 handles common thermoplastics such as PP, PE, PS, ABS, SAN, and many grades of PC, nylon (PA), and PET when processed with appropriate drying and temperature control. It is suitable for thin‑wall parts, small precision components, overmolding of inserts, and moderately complex geometries. For high‑performance engineering polymers (e.g., PEEK) or very large parts, check thermal and clamp force limits and consider specialized machine options.

What are the recommended steps for setting up the N308 for a new mold and first production trial?

Key setup steps: (1) Verify clamp force and platen size match the mold; secure and align the mold correctly. (2) Check mold cooling circuits and connect temperature controllers. (3) Install appropriate screw/barrel and nozzle for the material; ensure dryers are ready for hygroscopic resins. (4) Load a process recipe close to resin supplier recommendations (temperatures, injection speed, hold pressure/time). (5) Run low-pressure mold filling and gradually increase to target parameters while observing flow, venting, and part quality. (6) Validate cycle time, adjust packing and cooling for dimensional stability, then run a short production sample set for inspection before full production.

What common production issues occur on the N308 and how can I troubleshoot them?

Common issues and remedies include: short shots — increase injection speed/pressure, raise melt temperature, improve venting or runner size; flash — reduce injection or holding pressure, check mold clamp force and alignment, inspect worn nozzle/mold surfaces; weld lines or flow defects — adjust gate location, increase melt temperature or injection speed, modify cooling balance; sink marks — increase packing/hold pressure or hold time, optimize cooling; burn marks — improve venting and reduce barrel back pressure or injection speed. Use cavity pressure or in-mold sensors when available for more precise tuning.

What routine maintenance and safety practices are recommended for the N308?

Maintenance: perform daily checks of hydraulics/electrics, oil level and cleanliness, platen tie bars and mold clamps, screw/barrel condition, and hopper/dryer operation. Weekly checks: cooling lines, filters, and safety interlocks. Monthly: hydraulic oil sampling, tighten fasteners, and check belts/hoses. Safety: always use mold guards and interlocks, verify emergency stop functionality, lock out/tag out during maintenance, and follow manufacturer guidelines for safe press and high-temperature component handling. Keep an up‑to‑date maintenance log.

How can the N308 be integrated into an automated production line and what peripherals are commonly used?

The N308 can be paired with part removal robots, vision inspection, conveyor systems, and pick‑and‑place equipment for hands‑free operation. Common peripherals: linear robots or 6‑axis arms for part extraction, sprue/puller systems, hot runner manifolds, mold temperature controllers, dehumidifying dryers for hygroscopic resins, in-line inspection (camera or dimensional gauges), and servo-driven feeders. Integrating PLC/communication protocols (Ethernet/IP, Modbus, etc.) and using SPC/cavity pressure data helps achieve high OEE and consistent part quality.
