FAQ

What kinds of products and industries is the ONGO N series N388 best suited for?

The N388 is designed for general-purpose to precision injection molding across many industries. Typical applications include consumer housings and components, automotive interior parts, medical device housings (non-implantable), packaging caps and closures, electrical connectors, and household goods. It handles both high-volume production runs and shorter runs that require quick mold changes or frequent color/material swaps.

Which plastic materials can I run on the N388, and are there any limitations?

The N388 is compatible with most thermoplastics commonly used in injection molding, such as PP, PE, ABS, PS, PC, POM, PA (nylon) and many filled or reinforced grades. Limitations depend on the machine’s barrel and nozzle options, hot-runner compatibility, and melt-handling accessories: - High-temperature engineering plastics (e.g., some PEEK grades) may require special barrel heaters and tooling. - Heavily filled or abrasive materials may need hardened screws, barrels, and wear-resistant nozzles. - Hygroscopic resins (e.g., PA, PET) require proper drying and moisture control before feeding.

How do I size the machine for my part (clamping force, shot capacity, cycle time)?

To size the N388 correctly: - Calculate projected area of the largest part and multiply by expected peak cavity pressure to estimate needed clamping force; add margin for flash prevention. Consult the machine’s clamping force chart for the exact model variant. - Match the required shot volume (including sprue and runners) to the machine’s injection capacity — the N388 should list max shot volume in its datasheet. - Cycle time depends on polymer, part wall thickness, cooling design, and injection speed. Use pilot runs or mold simulation to estimate cooling time; optimize mold cooling and ejection to reduce cycle time without sacrificing quality.

What tooling and mold considerations work best with the N388?

For reliable production: - Design balanced runner systems and adequate cooling channels; uniform cooling reduces warpage and cycle time. - Use proper venting to avoid burns and short shots; place vents at flow fronts and under parting lines. - Choose gate types (hot tip, valve gate, edge gate, tunnel gate) based on part aesthetics, cycle time, and gating location flexibility. - Specify mold mounts and plate dimensions to match the machine platen pattern; verify tie-bar spacing and tonnage distribution. - For multi-cavity or family molds, ensure consistent cavity filling and consider sequential valve gating for thick/thin variations.

What are common troubleshooting steps for typical molding defects on the N388?

Quick checks for frequent issues: - Short shot: increase injection speed/pressure, check barrel temperatures, improve venting, and verify screw recovery and feeding. - Flash: increase clamping force, inspect mold alignment and parting surfaces, check for worn ejector/pins, and reduce injection overpacking. - Sink marks/voids: reduce packing delay, increase pack/hold pressure/time, improve cooling around thick sections, or redesign wall thickness. - Warpage: optimize cooling balance, adjust packing profiles, increase mold temperature if appropriate, or modify rib and wall thickness. - Burn marks: reduce melt temperature or injection speed, improve venting, and check for contaminants in material. Also review maintenance logs, mold condition, and consistency of raw material moisture and viscosity.

What installation, safety, and maintenance practices should I follow for the N388?

Installation: - Ensure adequate foundation or floor strength, correct leveling, and space for mold handling and maintenance access. - Provide suitable power supply, grounding, industrial compressed air, chiller/cooling water, and exhaust where required. Safety: - Use machine guards, mold safety blocks, interlocks, emergency stops, and implement lockout-tagout for maintenance. - Train operators on safe start-up/shutdown, mold changes, and handling of hot parts and resins. Maintenance: - Daily: clean surfaces, check hydraulic oil level/temperature, inspect hoses and connections, and verify safety interlocks. - Weekly: lubricate moving parts, check filter condition, and inspect screw/barrel for wear signs. - Monthly/quarterly: change hydraulic filters, monitor oil quality, inspect heaters and thermocouples, and verify servo/hydraulic system performance. Keep a preventive maintenance log and schedule professional service for major calibrations or hydraulic/oil replacement intervals recommended by ONGO.
