What Will a Traditional Ejector Pin Cost You?

Many injection molders reach for traditional ejector pins because they seem affordable at face value. Unfortunately, they don’t realize there are hidden costs associated with them. If you’re running a four-cavity mold for 500K shots each year, you can expect an average material scrap rate of about 8%, which can cost you $96,000 annually. What’s more, traditional ejector pins require a great deal of maintenance. You may need to take the mold out of production as often as every five days. This will cost you approximately $45,000 each year in manual inspection personnel costs, along with about 850 hours of mold downtime for another $63,000 per year. And it doesn’t stop there. Traditional ejector pins do not thoroughly eliminate gas traps, which results in defects in the finished product. Customer rejection can cost $100,000 to upwards of $1 million per year—and that doesn’t even include the damage inflicted on your professional reputation. The real question isn’t: “How much will a vented ejector pin cost?” It’s actually:
“How much will it cost me NOT to use a vented ejector pin?”

How We’re Transforming the Injection Molding Industry

At Next Chapter Manufacturing, we believe the injection molding industry is in dire need of transformation that strives for a 0% scrap rate and greater operational efficiency. Instead of venting the line, which results in substantial and unnecessary costs, we prefer to vent the part. Our vented ejector pin offers up to 15 times the amount of venting that conventional ejector pin venting provides. You can look forward to the elimination of gas traps and pin clogging, and the significant reduction in costs associated with defects. Plus, our vented ejector pins are:

  • Low maintenance, requiring only minimal, occasional ultrasonic cleaning
  • Dual-purpose, providing both venting and ejection
  • Proactive when it comes to reducing wear and tear on molds

In short, we’re setting the new standard for the injection molding industry.
