Mass production technology for large insert molded products

We have been mass producing automotive battery components since 2012.

The sizes, shapes, and materials vary widely, from those for electric vehicles to HV vehicles.

This time, among the products we have worked on in the past, there are battery case parts with many insert nuts and collars.

We would like to introduce some of the battery case parts we have worked on in the past, which have many insert nuts and colors.

・Product Shape

　　　　　 　Product Dimensions ：790mm×232mm×106mm

　　　　　　　 Material ：PBT GF-30

　　　　　　　　　　　　　Fittings : 43 (insert + post-press fitting)

　　　　　　　　　　　　　Gasket : 1 pcs.

　　　　　　　　　　　　　　　　　　List of fittings used　

▶Dimensional accuracy required

Due to the large size of the product, it was a challenge to clear the positional degree of Nat and Collar.

Because battery components must be assembled with mating components, the products themselves often have strict dimensional and geometrical tolerances.
