Replacement Gears for Appliances & Equipment
Many appliances are designed with a sacrificial plastic gear — the part that fails on purpose so the motor survives. Manufacturers know it. Repair shops know it. The problem is buying the gear: OEMs stop stocking it or price it like a new machine. We mold and machine replacement gears in production-grade resin and keep them in wholesale supply.
Flagship Program: Stand Mixer Worm Gear
The most famous sacrificial gear in the appliance world: the worm follower gear in tilt-head and bowl-lift stand mixers. When the mixer jams, this gear strips — protecting the motor and gearbox. It is a wear item by design, and millions of mixers in US and European kitchens will need one eventually.

More Sacrificial-Gear Programs
The same pattern — one plastic gear designed to fail, OEM supply slow or discontinued — repeats across appliance categories. Send the model number and we confirm fitment from our tooling list or measure your sample.
Kneading paddle drive gears and belts pulleys — the #1 failure point on most brands.
Timing and hook drive gears for discontinued domestic and industrial models.
Motor drive pulleys, incline gears and roller bushings — high-wear, high-repeat items.
Drive couplers and gear sockets — the classic sacrificial interface part.
Brew-group and dispensing gears for operators maintaining fleets.
Fuser and feed gears for long-life machines whose OEM parts ended years ago.
How It Works
Model Number or Sample
Quote from our existing tooling list, or send the stripped gear — broken is fine, we measure what matters.
Fitment Confirmed
First article in production resin, checked against the original — tooth profile, hub, and press-fit.
Stocked & Restocked
The mold stays with us. Reorder at your locked price whenever your shelves run low.
Materials That Match the Original
Sacrificial gears must fail at the right load — too soft and they strip early, too hard and they take the motor with them. We mold in POM (acetal), PA66 and glass-filled PA to match the original failure behavior, with machined steel or brass hubs where the original used them. Material certificates and batch dimensional reports are available with every lot.
One gear keeps a machine out of the landfill.
