3d render of the part design for the cable bracket.
The part design was provided by a leading client in the Automotive Industry. We preferably work with STEP files as input from our clients.

Next step is converting the STEP file into a mold design which is done by inverting the part into a cavity, in a block of material, and then adding the inlet gate(s) and initial venting.

Assembled 2 part mold.
The part size of the design was large. We split the design over 2 mold units and assembled them.

Freeform Injection Molding (FIM)
3d printed mold tool in aluminum tool frame.
The parts were molded on a 50-ton Krauss Maffei. Our molds work hand-in-hand with any installed base molding unit.

An aluminum mold frame was used to hold the large combo mold in place.
2-3 days

The Addifab alkaline solution was used for demolding these parts, over a 2.5 day period.

This can be time-optimized by mold re-design or by removing a part of the mold before demolding.

The bracket above, is the first out of tool: no post-processing, no polishing. Details in design and functionality, stand out clearly. 
Total time to 1st injection molded part:

6 hours 50 minutes +
2-3 days of demolding

The mold design is an easy process.

The material (BASF Ultramid) seems to fill the molds nicely in the first test rounds.

Optimization for demolding is always a good thing, running the next iterations.

Datasheet materials were used for molding data, settings, pressure, temperatures, and more.

‍Changing Design, Materials, or both - based on obtained results, are just some of the benefits from working with Freeform Injection Molding
Live testing for 9 weeks:

Mounted cable bracket for live testing in high-end sports car.
The parts were mounted in a range of high-end sports cars.

- The part is located directly on top of the Turbo Charger in the engine area.

- They were live-tested for more than 9 weeks.

- Extreme temperature conditions were applied.

- Humidity testing.

- UV testing.

- Vibration testing.

- Mechanical performance testing.

The parts passed all tests.
