Protection and climate
BAM's Hightech shell is built in three layers: ABS on the outside, a foam core of injected polyurethane or, depending on the model, Airex in the middle, and a third layer of PETG or ABS on the inside. BAM thermoforms these shells in France, with part of the production based in Thailand.
The interior is foamed in a single piece and set firmly into the shell; as the instrument is fitted, the padding yields to its shape.
The three-layer shell works as a buffer against swings in temperature and humidity. Open the case after moving into a different climate and the instrument meets the new conditions gradually rather than all at once.
A shady spot suits the shell best: in full sun, for example in a parked car, it can warp or blister.
With bows, length matters, as fine bows are usually a little longer than simple ones.
The bow responds to humidity too: on our violin bows, damper air makes the hair heavier by up to around 1 g.
Our experience
Our experience from shipping is clear: an instrument travels far more safely in a BAM case than in a cardboard box. Every case we deliver passes through our own quality check first.
We make small scratches on the shell almost invisible with ordinary car polish, and we leave alcohol and white spirit well alone.
We get a loose rotating bow holder to hold again by packing the screw holes with small pieces of a wooden toothpick, with no glue at all, whose residue would harm the velour.
Frequently asked questions
Why does my case weigh a little more than stated?
The stated weight is the net weight without straps. Because the density of the plastic varies slightly, an individual case can weigh around 100 g more.
Can BAM cases be stacked?
No, BAM cases should not be stacked; give each case a place of its own.
Can a cracked shell be repaired?
BAM replaces the complete upper or lower shell in France, as a crack cannot be repaired locally. Smaller damage such as pushed-in feet can be fixed with patches.
