Injection Molding - Riganelli Engineering

Why it matters

Test with real molded parts before committing to production tooling

3D printed and machined prototypes are excellent for validating form and fit, but when you need to test with parts that have the exact same material properties as the final production part, injection molding is the answer. Molded prototypes behave like production parts - because they are production parts, just made in smaller quantities.

Our in-house injection molding machine handles parts up to 2 oz, and we make the molds ourselves. We can 3D print molds for the fastest possible turnaround, or machine them from aluminum on our 5-axis CNC for greater accuracy and durability.

Production-accurate prototypes

Molded parts have the exact same material properties as final production parts. Mechanical testing, fit checks, and user testing all produce results that translate directly to real-world performance.

Molds made in-house

We don't wait on external tooling vendors. Molds are either 3D printed for maximum speed or CNC machined from aluminum for greater precision and durability. Both options are produced in-house.

Fast turnaround

From approved design to molded parts in as little as 1 week. This speed allows us to test with real molded parts early in the development process, rather than waiting until the end when changes are expensive.

Test before committing to production tooling

Production injection molds are a significant investment. By validating the design with in-house molded prototypes first, you confirm that the part geometry, material, and fit are all correct before committing to expensive production tooling.

Capabilities

In-House Injection Molding

Our small custom injection molding machine handles parts up to 2 oz - ideal for the small components, enclosures, covers, and other molded parts typical in product development. The machine is set up for quick changeovers, allowing us to run different parts and materials efficiently during the prototyping phase.

3D Printed Molds

For the fastest possible turnaround, we 3D print molds using materials designed to withstand the injection molding process. These molds are ideal for initial testing and design validation when speed matters most - allowing us to produce molded parts in days rather than weeks. Best suited for lower-volume runs and less demanding materials.

CNC Machined Aluminum Molds

When greater accuracy, tighter tolerances, or more demanding materials are required, we machine molds from aluminum on our 5-axis CNC. These molds offer better surface finish, longer life, and the precision needed for parts with tight dimensional requirements. They're the right choice for higher-volume prototype runs or when the molded parts need to closely represent production quality.
