Assists Can and Bottle Manufacturers to Scale Machine Speeds

High-volume bottle and can manufacturing necessitates precise, repeatable, and accurate equipment to meet industry demands for smooth, consistent, and high-volume production. Zero-Max stands as a premier supplier of custom and standard Composite Disc (CD) Couplings, ETP Keyless Shaft Bushings, and additional motion control components meticulously designed to cater to the most demanding production cycles. Zero-Max components are engineered to seamlessly integrate into existing systems, requiring only a turn of a screw to minimize changeout downtime and enhance accuracy. Whether your manufacturing expertise encompasses can manufacturing, printing, stamping, bottle forming, filling, or any other specialized process, Zero-Max offers tailored solutions to optimize your processes. Components for 2-Piece & 3-Piece Can Manufacturing ETP Keyless Shaft Bushings are hydraulic-based keyless bushings widely used in the can industry for their rapid and effortless installation, exceptional precision, zero-backlash operation, and remarkable accuracy. ETP bushings ensure the highest level of concentricity for connected components, with some models offering as low as 0.0002” Total Indicated Runout (TIR), or even less for the component-to-shaft connection. These bushings are perfect for manufacturing processes that demand high-speed operations, requiring quick and easy mounting of shaft components, the ability to execute frequent change-overs or rapid re-adjustments, and where precision is paramount. They are employed daily in various can manufacturing systems, and those with manufacturing speeds of up to 2,400 cans per minute or faster for Necker Lines and various other can manufacturing processes. Zero-Max also offers a specialized ETP-KN Knife Holder Bushing for trimming the steel used for the sidewalls of 3-piece cans. These bushings are securely attached to the slitter knives and utilize a single actuation screw to lock the Knife Holder Bushing to the shaft. The operator can effortlessly slide the ETP-KN into position and swiftly lock it in place with a single turn of a screw. This saves valuable time and money by enabling quick and easy positioning and re-positioning while ensuring precise control over the can profiles. The ETP-KN design exhibits less than 0.0004” axial runout of the slitter knife, providing an accurate trim length and minimizing wear on the slitter knife. Additionally, they offer fast and easy removal for re-sharpening the slitter knives as required. These ETP-KN Bushings are ideal for high-volume, highly repeatable can manufacturing processes. CD Couplings are also used in precision processes that are often servo-driven and position sensitive.  Just one example is on a servo-driven Denester, which separates a single can lid from a stack of lids and then delivers it to a pocket in a conveyor belt. Precision and accuracy are necessary to allow the servomotor to deliver the single can lid at the proper time within the machine cycle, relative to the conveyor belt position. The high torsional stiffness and zero-backlash operation of the Zero-Max CD Coupling makes it ideal for this precise application. 

 Can Printing and Decorating Applications

Multiple changeouts in can printing processes can lead to lost production time and revenue. Zero-Max ETP-Keyless Shaft Bushings offer a quick, easy, and precise solution to reduce costly downtime. These keyless bushings are designed for easy installation and withstand the printing registration requirements of high-speed production. ETP Connections ensure precise concentricity on the registered print zone, resulting in accurate and repeatable production. In can stamping operations, timing is crucial. Zero-Max ETP-TECHNO Keyless Shaft Bushings simplify the process by allowing a user to loosen a single screw and set the desired rotary position. This adjustment method is significantly faster than standard mechanical bushings, which typically require the actuation of multiple screws for dismantling and reassembly. ETP keyless shaft bushings maintain the phasing and timing in stamping operations, preventing other costly issues from arising throughout the production line. They provide a robust solution to handle demanding high indexing cycle rates and the associated high acceleration and shock loads at various stages of the can stamping process.
