Boxy housing case with airtight seal-weldable tetragon side walls

We are producing and supply boxy housing cases to be airtight seal-welded at the wall top to other assembly piece. In general, tetragon side walls of injection molded boxes have warpage due to a plastic melt flow, distribution of shrinkage and/or fiber orientation and this warpage often causes leakage from seal part.

Our boxy housing cases enabled durable sealing through geometrical compensation of mold shape by measurement & feedback.
