A silicone gun is a handheld tool for dispensing caulk from a tube, with a frame that holds the cartridge, a trigger-activated plunger rod, and a nozzle. The trigger pushes the plunger forward, forcing the sealant out of the tube in a controlled flow. When the trigger is released, a "braking" mechanism stops the rod from retracting due to the pressure inside the tube.
Structure
- Frame: The main body of the gun, often made of aluminum, steel, or plastic, that holds the cartridge.
- Cartridge Holder: The part of the frame designed to securely hold the caulk tube in place.
- Trigger: A lever at the rear of the gun that is squeezed to operate the mechanism.
- Plunger Rod: A rod connected to the trigger that pushes forward into the caulk tube to dispense the material.
- Braking Mechanism: A system, often called a "braking plate," that prevents the plunger rod from being pushed back by the pressure inside the tube once the trigger is released.
- Nozzle:The tip at the front of the gun where the sealant exits, determining the size and shape of the bead.
Tube Silicon Gun
- Cartridge: A tube, typically made of plastic, containing the sealant.
- Loading: To use the gun, the front of the tube is cut, and the tube is inserted into the cartridge holder.
- Dispensing: The plunger rod is inserted into the back of the tube and pushed forward by the trigger mechanism, forcing the sealant out of the nozzle.
- Unloading: To remove an empty tube, the trigger is released, and the plunger is pulled back.
