Part Design<\/strong><\/h3><\/div>

This part design was provided by a leading global automotive manufacturer based in Germany. STEP files are preferred for FIM.<\/p>\n<\/div>

60 minutes<\/h3><\/div>

Mold making<\/strong><\/h3><\/div>

The next step is to convert the STEP file into a mold design. To do this, the part is rotated into a cavity in a block of material, and then the inlet opening(s) and the first vent are added.<\/p>\n<\/div>

2 hours<\/h3><\/div>

Print tools<\/strong><\/h3><\/div>

As it was a large piece, the mold was divided into two parts and put together.<\/p>\n<\/div>

5 minutes<\/h3><\/div>

Freeform Injection Molding (FIM)<\/strong><\/h3><\/div>

The parts were formed on a 50-ton press. The FIM molds work hand in hand with every installed basic molding system.<\/p>\n

An aluminum mold frame was used to hold the large mold assembly in place.<\/p>\n<\/div>

1 day<\/h3><\/div>

Demolding<\/strong><\/h3><\/div>

The alkaline Nexa3D solution was used to demold these parts over a period of 2.5 days.<\/p>\n

This time can be optimized by redesigning the mould or by removing part of the mould before demoulding.<\/p>\n

The holder above comes straight from the tool: no post-processing, no polishing. The details in the design and the functionality of the part stand out clearly.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

Total time to the injection-molded part:<\/strong><\/h2><\/div>

3 hours 5 minutes + 1 day demolding<\/h2><\/div><\/div><\/div>
