Injection Molding

Injection molding is the process of choice for companies looking to produce repeatable parts with strict mechanical requirements. It’s a popular option for high-production runs, not only because of the consistent part quality, but because price-per-part decreases with higher quantities. With Fast Radius, companies can expect low labor costs, minimal post-processing, high production speeds and volumes, and low scrap rates.

Producing parts with injection molding

Max. part size

• 2000 x 1500 x 800 mm
• 78.7 x 59.0 x 31.5 in

min. feature size

• 5 x 5 x 5 mm
• 0.2 x 0.2 x 0.2 in

best achievable tolerance

• +/- 0.05 mm
• +/- 0.002 in

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

Max. press size

• 1400T

Min. order size

• 100 parts and $5000

Setup fee

• $500 per mold per order (applies to sample runs after initial T1 samples or engineering changes)

RAPID TOOLING

• Molds with aluminum cavity and core with a shot life of 5,000-10,000 shots
• Typically machined in 2 weeks

PRODUCTION TOOLING

• P20 steel tool with shot life up to 1M shots
• Ability to integrate side-pulls or cam-actions
• Typically machined in 3 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

OVER-MOLDING

• Premade parts are placed into the mold and molded over
• Allows for multi-material injection molding
