What is injection molding?
Injection molding is used to create strong, durable plastic parts and is ideal for manufacturing projects with high volume production requirements. During the injection molding process, molten thermoplastic is injected into a metal mold and then cooled to form consistent and durable solid parts.
Get your injection molding project started today. Upload your CAD file to our Cloud Manufacturing Platform™ to receive a quote, work with our engineers to optimize your design, and move to production when you’re ready. You can specify the post-production and finishing options you need for your parts, along with any inspection requirements. When your order is ready, we’ll package and ship the finished parts to you.
Explore our injection molding service
Reliable and cost-effective, plastic injection molding is commonly used for high volume production runs but is also suitable for prototyping. Our injection molding service also includes the following sub-capabilities:
Insert molding
Insert molding involves the injection of molten thermoplastic around a pre-placed insert to create strong, durable prototype parts.
Overmolding
Overmolding is a process in which multiple shots of thermoplastic are injected over or around a substrate to create highly customizable prototype parts.
Multi-cavity/family molds
Multi-cavity molds and family molds, enable the production of multiple injection molded parts from a single shot of thermoplastic.
Injection molding applications
The injection molding process is precise and consistent, and used in a variety of industrial applications:
High volume production
Injection molding is ideal for high-volume production runs of identical plastic parts – and becomes more cost-effective with larger orders.
Customer end-use
Injection molding is capable of creating strong, durable, parts for an array of customer end-uses, including toys, plastic bottles, scissors, screwdrivers, remote control coverings, and case assemblies.

Injection molding production considerations
Optimize your injection molding project with these key production considerations:
General process information
| Maximum part size | 800 x 800 x 400 mm 31.5 x 31.5 x 15.7 in |
| Minimum part size | 1 x 1 x 1 mm 0.04 x 0.04 x 0.04 in |
| Tolerance | Best achievable tolerance: ±0.001″ (0.025mm) Standard: ±0.005″ (0.127mm) For larger part tolerances please contact a Fast Radius engineer |
| Lead time | As low as 2 weeks for T1 samples After T1 sample approval, lead time for < 10,000 parts is as low as 1 week |
| Tool validation | Standard process is to produce a small set of T1 samples for approval before initiating full production |
| Maximum press size | 1600T |
| Minimum order size | 100 parts and $5000 |
| Set-up fee | $500 per mold per order (applies to sample runs after initial T1 samples or engineering changes) |
Tooling information
| Production tooling | Steel tool with shot life up to 1M shots Ability to integrate side-pulls or cam-actions Typically machined in 3 weeks |
| Rapid tooling | Molds with steel cavity and core with a shot life of 5,000-10,000 shots Typically machined in 2 weeks |
| Multi-cavity or family molds | Multiple identical cavities or family of parts machined into a single tool Allows for more parts to be produced per shot, minimizing unit costs |
| Insert molding | Inserts are placed into the mold and molding occurs around them to extend tool life for critical features Allows for inserts such as helicoils to be molded in your design |
| Insert molding | Premade parts are placed into the mold and molded over Allows for multi-material injection molding |
Injection molding case studies
Our injection molding services solve manufacturing challenges for organizations around the world. Learn more about the ways that our work creates an impact.
Making safer working conditions possible
In order to meet urgent demand during the Covid-19 crisis, we needed to ramp up production of face shields for frontline workers. To achieve this, we transitioned a 3D printing design to injection molding, and got tooling up and running quickly.
