Silicone Rubber Molding vs. Overmolded TPE for Sealing and Grip Features
Material choice hinges on temperature limits, then chemical exposure, then bonding needs.
Material choice hinges on temperature limits, then chemical exposure, then bonding needs.
Die casting wins at high volume, but machining often costs less until you're ready to commit.
Aluminum tooling often beats urethane casting on total cost in the 100 to 500 unit range.
CNC wins on precision and stability; resin trades accuracy for speed and cost.
Binder jetting wins on geometry but CNC owns tolerance, finish, and strength for stainless housings.
DMLS wins for complex geometry; CNC dominates simple, high-volume brackets.
SLM wins where CNC geometry fails entirely, but powder escape holes are non-negotiable.
Aluminum tooling wins past 300 parts once labor replacement cycles are factored in.
CNC Delrin outperforms SLS nylon on precision and moisture stability.
CNC machining delivers isotropic strength; FDM prints weak along the Z-axis.
Pick CNC for functional tests on aluminum; SLA fails mechanical and thermal ones.
Know your break-even volume or overpay for brackets every single month.
