NESMS: Trusted Partners for Custom Manufacturing Equipment

The story of modern closure lining begins with Nestech’s own history. In the 1970s, Steve Foldesi Sr. designed the first high-speed lining machine, setting the initial benchmark for the industry. Today, as his legacy continues, Nestech remains on the forefront of technology, constantly innovating while other lining machine manufacturers lag behind.

Our specialization in machinery for closure lining ensures that every cap liner, regardless of material, is handled with meticulous care and precision. We handle a vast range of materials, from heavy pulp to the thinnest induction liners, all running through our machine closure lining systems with remarkable ease.

The Precision Dieset Advantage

Secondary Slitting vs. In-Mold Slitting

The integrity of the break-away ring is essential, and the method used to create it makes all the difference. Nestech champions secondary slitting—slitting the cap as a distinct operation after molding—as the superior method, offering substantial technical and economic advantages over slitting done in the mold:

Reduced Costs and Maintenance: When slitting is done in the mold, the cost of the mold and the associated maintenance requirements are drastically higher. By performing slitting as a secondary operation, these costs are significantly reduced.

Product Integrity: There is a considerable danger that a weakened cap will be damaged upon ejection from the mold if the tamper-evident ring has been pre-cut. Nestech’s machine slitting eliminates this risk entirely by processing the cap once it is stable.

Our machine slitting process creates a series of precise cuts and bridges in the cap wall. These bridges are what hold the band in place until the consumer twists the cap, providing immediate evidence of tampering if they are broken.

Unheated Knives and Versatile Designs

Nestech’s technology accommodates various closure designs, including recent hinged designs where the cap stays with the bottle. Our slitting knives either cut against molded posts or form bridges as required by the closure design.

We employ both straight knife and traditional curved knife slitting processes to produce the breakaway tamper-evident ring. A key technological advantage is that our knives do NOT need to be heated, which simplifies the process and reduces energy consumption. Furthermore, Nestech machines are versatile enough to control the final outcome: bands can be cut to completely break away upon opening or retained on the bottle, based on your specific application and market needs.

Our machine closure lining and slitting systems work in perfect synchronization; once the caps are slit, they are completely processed and ready for the final step: lining, or in many cases, assembly.

Precision in Motion: High-Speed Closure Assembly

Nestech has established itself as a world leader in closure or cap assembly, a demanding process that requires extreme speed and infallible accuracy. Our core technology in this area is the incredibly versatile T-12 rotary continuous motion turret.

Speed and Scale: The T-12 Turret

The standard T-12 model features 12 heads, but for operations requiring higher throughput, we readily deploy 24 and 36 head units capable of reaching speeds around 1200 closures per minute. This high-speed capability ensures that the most ambitious production targets are met with ease and reliability.

The types of projects handled by our machine assembly equipment are widespread and constantly growing:

Child Resistant Caps (CRC) make up the majority of assembly projects, as these caps often involve multiple components that must be perfectly aligned and secured.

Sport drink caps and various flip-top caps are also common projects, which is why the most common sports caps found on beverages today are assembled with Nestech equipment.

Integrated Inspection and Ejection

A typical assembly project often consists of multiple parts—for example, a body, a valve slider, and a dust cover. The Nestech machine assembly systems handle the intricate task of bringing these components together and, crucially, inspecting the result in real-time.

Our machines are built with sophisticated inspection systems that check for any missing item from the assembly. Defective items, or those with components out of tolerance, are immediately and precisely ejected from the production stream, guaranteeing that only flawless, compliant closures move forward to the filling line. The process is smooth, continuous, and validated at every step.
