Understand Injection Molding

What is rapid injection molding?

At Great Jump, our rapid injection molding service is ideal for prototyping and small series production—offering cost-effective solutions and lead times as fast as 2 to 4 weeks thanks to our quick tooling capabilities. This process uses the same high-pressure injection molding technology found in mass production, ensuring excellent part consistency, fine detail, and high dimensional accuracy.


Rapid injection molding is perfectly suited for the automotive, consumer electronics, medical, electrical, and industrial sectors, allowing the creation of complex, functional components with production-quality finishes.

What can we do
