At Yantai Kunpeng Packaging Equipment Co.,Ltd, we often get requests for custom metal packaging parts, and one popular item recently has been hollow threaded aluminum caps for bottled essential oils. Many customers come to us not just for finished caps, but for a stable, reliable production line that can make them consistently.

Our customized aluminum thread cap production line handles the whole process in-house. We start with high-quality aluminum sheets, precisely cut to size. Our automated line forms the basic cap shape through multi-stage stamping and drawing-each step controlled to keep consistency across batches.
Next comes the hollow design and thread forming. Our specialized threading machine rolls uniform, tight threads on the inner wall, while precision punches create clean, even hollow patterns on top. This isn't just for looks; it helps slow fragrance release and keeps oil fresh longer.

Every cap goes through trimming, deburring, and surface treatment to avoid sharp edges and improve touch. We also run routine checks during production to maintain stable dimensions and fitting performance, which helps customers reduce assembly issues later.

What makes our line stand out? We can adjust cap size, thread specification, and hollow layout based on individual customer needs, whether for small-batch trials or stable mass production. For those in the aromatherapy and essential oil industry, these lightweight aluminum caps offer decent sealing and a premium look without excessive cost.
If you're looking for custom metal caps or a dedicated production line for bottled essential oil packaging, we can provide practical, targeted solutions based on your real production demands.
