The gating system of the plastic mold, as the "throat" through which molten plastic enters the mold cavity, directly determines the success or failure of the final product.
In urban nightscapes, garden landscapes, coastal walkways, and even high-altitude mountain lighting systems, lamps must not only illuminate the darkness but also remain steadfast in torrential rain, scorching sun, salt spray, and extreme cold.
When airflow carries dust into the dust cup, if only a single filter is used for filtration, large dust particles will quickly clog the filter pores, resulting in a decrease in suction power.
Traditional filters need to be replaced regularly, but users often delay replacement due to inconvenience or cost, resulting in decreased filtration efficiency.
Integrated plastic mold molding of this frame is a key path to achieving efficient and high-quality production. Achieving dimensional stability of ±0.05mm or even higher requires systematic optimization of the mold's structural design.
In modern homes, cleaning is no longer just about "visible dirt," but also about those invisible yet health-affecting particles—floating dust mite excrement, pet shed fur, and pollen and dander accumulated deep within carpets.
