A household or desktop plastic injection molding machine is a compact device used to melt thermoplastic pellets and inject them into a mold to create custom plastic items, toys, or replacement parts at a small scale.
Key Components
Hopper: Holds raw plastic pellets or granules (like ABS or PP) before they feed into the heating chamber.
Heating Barrel & Nozzle: Uses electric band heaters to melt the plastic to precise temperatures.
Injection Mechanism: A manual lever, pneumatic piston, or motorized screw that pushes the melted plastic forward.
Clamping Unit: Holds the two halves of the mold tightly together under pressure so liquid plastic does not leak out.
