Selecting the appropriate capping machine for your business can be a significant challenge, given the wide array of options available in the market. At Metramak, we are here to assist you in understanding the various capping machine alternatives before making a purchase.
1-Screw Spindle Capping Machines
This process initiates by creating a pathway for the closures, allowing them to be raised by a caps elevator feeder and directed towards the screw-spindle capping machine’s cap chute. The cap chute guides the cap onto two of its fingers, effectively sealing it. As one of the fingers finishes sealing a cap, the next bottle moves into position.
The capping station receives the closure-container combination. A stabilizer secures the cap, while a gripper ensures the container remains steady. The machine and spinning discs collaborate as the assembly advances through them, with the torque necessary for closing the container tightly being generated only at the third or fourth set of spindles. The rotating discs play a crucial role in achieving a secure cap closure.
2-Screw Chuck Capping Machines
Unlike screw spindle capping machines, which rely on vibratory bowls and cap delivery systems to release caps for storage in designated containers, screw chuck type capping machines operate differently. In these machines, indexing of the bottle under the capping head is achieved using a star-wheeled mechanism, allowing the bottles to move rapidly along the production line.
When the capper detects that the cap is positioned above the container, it gently lowers the capping head to secure the cap onto the chucks. This is accomplished with the assistance of torque generated by a screw chuck cap sealer.
3-Bottle Capping Machine – Press-Push
Press/Push-On bottle cap machines designed for both press and push-on bottle closures have the capacity to cap approximately 104-105 caps per minute on bottles or containers. These Press/Push-On Bottle Capping Machines are built using stainless steel and anodized aluminum, ensuring durability and extended service life.
Metramak offers Pressure Capacity / Push-On Bottle Capping Machines equipped with real-time production display. These innovative units electronically monitor the number of caps applied and the quantity of bottles produced each minute. Furthermore, there is an option to store capped information in a database for future reference when necessary.
4-ROPP Capping Machine
ROPP (Roll-On Pilfer-Proof) capping machines are designed to manufacture screw caps that are used for sealing and corking plastic containers with threads on the top of the caps. Typically, these containers lack threads and are instead provided with a metallic blanket, often made of anodized aluminum.
The caps are applied by a roll-on bottle capper, which creates looping loops inside the cap. Unlike machines that transfer torque and require a clutch, the roll-on bottle capper machine does not. These machines feature multiple spouts to ensure a perfect seal, resulting in tamper-proof bottles.
It’s important to note that converting a roll-on bottle capping machine to handle various cap types is a complex task. This implies that the bottle itself needs to be robust enough to withstand the pressure and adapt to different cap types.
Absolutely, the choice and design of capping machines are indeed influenced by the type of product they are intended to process. Different containers, such as bottles, jars, cans, and tins, require unique capping solutions, each tailored to their specific requirements. Furthermore, the operational model of these machines can vary significantly based on the type of product you intend to cap, as the characteristics of the product often dictate the ideal capping method and equipment needed for the task.
