12-Cavity Tea Powder Cap Lower Cover Mold – High-Cavitation Inner Plug Mold

Precision 12-cavity tea powder cap lower cover mold by Taoyuan Mould. Designed for inner sealing lids, sifter bases, and plug covers for tea powder, protein powder, and nutritional supplement containers.

Product Description (for website)

Taoyuan Mould – Professional Bottle Cap Mold Manufacturer

We present our 12-cavity tea powder cap lower cover mold, engineered for producing the inner base / sealing plug of two-piece powder caps. This high-cavitation mold is optimized for thin-walled, tight-tolerance components used on tea powder cans, protein tubs, and supplement jars.

The lower cover typically features a sifting hole pattern, sealing ring, and snap-fit structure that mates with the upper flip-top lid.
