NP-LC Spindle Capping Machine

NPACK NP-LC Six-Spindle Capping Machine is engineered to fulfill the rigorous requirements of contemporary packaging lines. Featuring a durable build and cutting-edge design, this machine presents an optimal solution for enterprises aiming to enhance their bottling and sealing processes. It is exceptionally well-suited for a variety of sectors, including pharmaceuticals, cosmetics, food, and beverages, offering unparalleled versatility and dependability. This machine is tailored to support businesses in achieving efficient and reliable capping operations, ensuring product integrity and quality.

1. The principle we follow is ‘one motor per capping wheel’ to ensure the machine operates reliably with consistent torque even during prolonged usage. This new design guarantees that each capping wheel functions on its own, minimizing the chance of mechanical malfunctions or interruptions while capping. Having this dependable system installed, manufacturers can rest assured that their production line will operate smoothly and effectively.
2. Variable clamping belts increase the machine’s ability to adjust to different packaging needs by capping bottles of varying heights and shapes. Our machine can handle both tall bottles and irregularly shaped containers with ease. The flexible clamping belts provide a firm hold on every bottle while capping, avoiding any slipping or misalignment that could impact the quality of the product.
3. An optional cap guiding system can be integrated, making the machine compatible with pump caps and expanding its versatility. By incorporating a cap guiding system into our machine design, we offer manufacturers greater flexibility in their packaging options. Pump caps are commonly used for products such as lotions or creams, and our machine’s compatibility with these types of caps allows for seamless integration into diverse production lines.
4. Equipped with a convenient construction adjustment system that includes a precise ruler and counter, this feature allows for easy and accurate adjustments. Our goal is to simplify setup procedures for operators while ensuring precision in every adjustment made. The inclusion of a precise ruler and counter enables operators to make quick measurements and track changes accurately without relying on guesswork.
5. The machine’s mainframe is designed with efficiency and convenience in mind. Equipped with a powerful motor, it effortlessly lifts and lowers to accommodate different bottle sizes, ensuring seamless adjustments during the production process. The adjustable two-belt height feature further enhances its versatility by allowing for easy adaptation to various bottle dimensions.
6. To ensure the utmost protection of caps, the capping wheels are thoughtfully crafted from a soft material. This not only prevents any potential damage to the caps but also guarantees their integrity throughout the packaging process. Additionally, an advanced servo system complements these wheels, providing precise control and enhancing overall performance.
7. With these advancements at hand, manufacturers can confidently rely on this machine to efficiently handle bottles of all shapes and sizes without sacrificing quality or productivity levels.

Using Spindle Cappers as Cap Tighteners

Spindle capping machines aren’t just built for fully automated lines—they also shine when tasked as reliable tighteners for hand-placed or trigger-style caps. For manufacturers handling manually positioned caps, these machines offer a significant advantage: once an operator places a cap onto a bottle by hand, the spindle capper efficiently secures and tightens the cap to consistent torque specifications.
This approach is especially useful for unique cap types, like trigger sprayers or flip-top lids, often found in home care, cosmetics, or specialty food products. When operators manually set these sometimes irregular caps in place, the spindle capper engages, steadily tightening each one without overtightening or stripping threads.

Manual placement, automated torque application: Operators initiate the capping process, while the machine ensures each cap meets quality requirements.
Adaptability for various cap styles: Whether you’re working with standard screw-on lids or more complex trigger-style caps, the spindle capping mechanism accommodates a wide range of designs.
Seamless upgrades: Should production needs expand, these machines can be further automated by integrating sorting or feeding systems—transitioning from a supportive role in manual lines to a fully automated capping solution.

By bridging the gap between manual processes and high-speed automation, spindle cappers help businesses maintain both flexibility and consistency on the packaging line.
