Expert Solutions: A Newark Success Story
Recently, a tech firm located near Military Park in Newark faced a critical failure. Their previous supplier provided parts that couldn’t handle the humidity and temperature fluctuations of the Northeast. Their launch was three weeks away, and they were staring at a total loss.
They contacted our team. From our Michigan facility, we re-engineered their mold for better thermal stability and utilized our rapid plastic prototyping service to validate the fix in 48 hours. We served their Newark team with daily video updates and overnight shipping, hitting their launch date with zero defects.
That is the difference between a vendor and an expert partner.
