Posted by eshuey on | Comments Off on Die Cutting Technologies Explained
When it comes to manufacturing precision adhesive components, gaskets, protective films and specialty materials, selecting the right die cutting technology can have a significant impact on cost, quality, production speed and scalability.
Many manufacturers know they need a die cut component, but determining how that component should be manufactured is often the more difficult decision. Should you use rotary die cutting? Flatbed steel rule dies? Solid steel tooling? Laser cutting? Or would a digital cutting table be the best solution?
The answer depends on your production volume, material characteristics, tolerances, budget, and long-term manufacturing goals.
At TPC Converting, our role isn’t simply to manufacture parts. We work alongside customers to evaluate their application and recommend the die cutting methodology that delivers the best combination of performance, efficiency, and total cost of ownership.
Different Types of Die Cutting
While all die cutting methods produce precision parts, each technology is designed for different production requirements.
Rotary Die Cutting
Rotary die cutting utilizes cylindrical dies mounted on a rotary press to continuously process material as it moves through the machine. This makes rotary die cutting one of the fastest and most efficient manufacturing methods for high-volume production.
In addition to cutting complex shapes, rotary presses can perform multiple converting operations during a single pass, including:
Lamination
Slitting
Sheeting
Scoring
Perforating
Liner changes
Island placement
Pneumatic knock-out
Automated stacking
Because several operations can be completed simultaneously, rotary die cutting minimizes handling, improves consistency, and reduces overall production costs.
Best Applications
Rotary die cutting is ideal for:
High-volume production
Pressure-sensitive adhesive tapes
Protective films
Labels
Medical and industrial components
Continuous roll-to-roll converting
For manufacturers producing thousands of identical parts, rotary die cutting typically offers the lowest cost per part.
Flatbed (Steel Rule) Die Cutting
Flatbed die cutting (often referred to as CNC or steel rule die cutting) uses a flat press equipped with a custom steel rule die to stamp parts from sheet material.
Unlike rotary converting, flatbed presses excel when working with thicker or more rigid materials that may not process efficiently through rotary equipment.
Steel rule tooling also provides an economical solution for medium production volumes or projects that don’t justify investing in rotary tooling.
Best Applications
Flatbed die cutting is commonly used for:
Foam materials
Rubber
Gasket materials
Thick adhesive constructions
Plastic sheets
Silicone
Fabric
Specialty materials
Because tooling costs are generally lower than rotary tooling, flatbed die cutting offers an excellent balance of flexibility and affordability.
Solid Steel Dies
Solid steel dies are precision-machined from hardened steel rather than assembled using steel rule blades.
These dies provide extremely tight tolerances and exceptional repeatability, making them ideal for demanding applications where dimensional accuracy is critical.
Although tooling costs are higher, solid steel dies often deliver longer tool life and superior consistency in high-volume production environments.
Best Applications
Solid steel dies are frequently selected for:
Tight tolerance components
High-precision electronics
Automotive components
Medical devices
Long production runs
Complex geometries
When quality requirements leave little room for variation, solid steel tooling often becomes the preferred solution.
Laser & Knife Cutting
Unlike traditional die cutting methods, laser and digital cutting systems eliminate the need for physical tooling altogether.
At TPC Converting, our knife cutting table allows us to quickly produce:
Prototype parts
Samples
Low-volume production
Design iterations
Custom one-off components
The knife cutting tables can:
Perform total cuts or kiss cuts on linered materials
Cut sheet materials
Produce gasket geometries
Punch holes
Score and fold materials
Because no tooling must be manufactured, customers can validate designs before committing to production tooling.
Best Applications
Digital cutting is ideal for:
Engineering validation
Product development
Prototype evaluation
Small production runs
Frequent design changes
For many projects, digital cutting serves as the bridge between concept and full-scale production.
This is why engineering consultation is such an important part of the process.

Posted by TPC Converting on | Comments Off on Revolutionizing Die-Cut Adhesive Application Through Automation
Die cutting is a versatile method for cutting distinct shapes from a roll or sheet of adhesive-backed materials including foams, woven and non-woven textiles, silicone, rubbers, abrasives, paper, foils, plastic, cork, and more. These die cut pieces are used in many applications such as:
During assembly, these cutouts must be positioned and applied carefully in exact locations on or inside products or components. When performed manually, this kind of task can be time-consuming and prone to human error, which leads to production bottlenecks and waste. Fortunately, automation is helping revolutionize the labor-intensive process of applying die cut materials. Not only does this reduce cycle times, but it also improves the accuracy and quality of application.
Keep reading to learn more about the benefits of automating the die-cut adhesive application process.
Features of Automated Die-Cut Adhesive Applicator Equipment
Automation is best for processes and operations that are highly repetitive and prone to human error. Peeling die-cuts from a backing and applying them with precision without wrinkles or bubbles, over and over, is a strong candidate for automation in high-volume production. Specialized applicator equipment has several key features that are well-suited to this type of work, such as:
Opportunity to Add Assembly Aids: Converting process capabilities allow for the integration of automated assembly aids like extended liners for easy removal, pull tabs for convenient access, and zone-coated adhesives for precise bonding areas.
High-Speed Operation: Automation equipment moves quickly along pre-programmed paths, and has built-in mechanisms designed to remove die cuts from backings or carrier strips efficiently. Machines also do not require breaks, and because each application is made correctly, no time is lost removing and fixing a misaligned piece.
Precision and Repeatability: Because all of the movements of the machine are pre-programmed, they are easily repeated until the machine is told to stop. Die cuts or labels are fed into the machine from uniform rolls or sheets, so the steps involved do not change from batch to batch, achieving in-tolerance placement, sometimes within 0.002 in. It’s also possible to adjust the process as designs or products change.
Advanced Automation Technology: Features like motion control, sensors, and conveyance advance items into position, prepare and apply the die cut or protective film with appropriate force. Precision application means there are no distortions or bubbles. Then, the finished item is quickly conveyed out of the machine as the next one is loaded.
Quick Changeover: Many automated solutions include a menu of product options or are compatible with QR codes to call up new sets of pre-programmed instructions to switch from one component or type of die cut to another.
Integrability: Automated applicator machines can often be integrated into an existing assembly or packaging line. In early stages of product development, they can serve as a key component in a new automated production plan. Of course, many can also be used as standalone equipment at a workstation.
User-Friendly: Modern automation equipment is designed to be intuitive, with clear graphical user interfaces (GUIs) and simple controls. Automated equipment is intended to simplify operator tasks for streamlined loading and unloading reels or stacks of die cuts, preparing a new batch of products to be labeled, or easily switching from one task to another.
Benefits of Automating the Application of Die-Cut Adhesives
If you’re looking to increase the accuracy, efficiency, and consistency of your die-cut adhesive application process, then now is the perfect time to consider automation. Benefits include:
Less Waste: Automated equipment improves the precision and quality of die cut applications, which results in fewer misaligned or damaged pieces, less waste, and less time spent removing and reapplying incorrect die cuts.
Ease of Use: User-friendly designs and GUIs reduce the learning curve needed to become proficient with the automated process and the machine. This allows personnel to feel comfortable working with it and helps them “buy in” to automation in their daily work.
Versatility: A dedicated machine can be used exclusively for one type of product or die cut material, or it can be used with multiple shapes or types of die cuts and substrates. Fast and simple changeover makes this equipment flexible.
Cost Efficiency: Investing in a robust automated system to apply die cuts allows you to scale production or expand product offerings without compromising on quality or adding staff.
Fast Cycle Times: While manual adhesive application is a meticulous, time-consuming process, automated applicators streamline the process with pre-programmed movements that prepare and apply die cuts and labels efficiently.
Labor Management: Time and labor saved due to automation allow personnel to oversee multiple pieces of machinery or be redeployed to higher-value tasks.
