Custom Die-cut Parts for Automated Assembly
Among numerous assembly options, automated assembly is often the method of choice for many of our customers. Automated placement is used for projects with very high volumes where precise placement is critical. Automated assembly can also significantly increase assembly speed and efficiency.
Marian designs and manufactures custom components to fit seamlessly into our customers’ automated assembly process. We can modify many different aspects of the final part and packaging from liner type, part spacing and orientation, and quantity of parts per roll.

Improvements are being made to the lithium-ion batteries used in electric vehicles. Auto makers are developing more powerful lithium-ion batteries that have increased range and charge more rapidly. Along with these improvements, enhancing safety has becoming increasingly urgent for electric vehicle development.
As mentioned in our previous blog post, 11 Considerations when Selecting Thermal Interface Materials for Electric Vehicle Li-Ion Batteries, Li-ion batteries produce a significant amount of heat while in use and while charging. Along with the use of thermal management materials, placing protective engineered flame-retardant insulating materials between the components of the battery cell, module, and pack can offer additional thermal and electrical insulating protection. However, adding such materials can be challenging due to space and weight constraints.
In this post, we outline four materials that can enhance the safety of lithium-ion batteries used in electric vehicles. Some shared characteristics of these four materials are listed below.
- ultra-thin
- lightweight
- electrically and thermally insulating
- flame retardant
- can be die-cut and laminated with PSA

Paint masking can be a tedious process. When masking an area with precision and over-masking is unacceptable, custom die-cut masks prove to be the best solution. Die-cut masks are pre-cut pieces of masking tape that are made to the exact size and shape of the surface area in need of masking. This video shows a direct comparison of the masking process with strips/knife versus masking with a die-cut part with a split liner. You'll see this demonstration proves that masking with a custom die-cut is easier, faster, more accurate, and safer.

The Shore durometer (pictured right) is a scale for measuring the hardness of a material, such as rubber, plastic, thermal
plastics (TPE), and rigid plastics. The term "durometer" is often used to describe a material's rating on the scale, for example “this material has a durometer of 60.”
It's worth noting, there are a variety of durometer scales since elastomeric and plastic resins vary over a wider range than one scale can accommodate. Download our comparison chart to see how these scales overlap.
Durometer hardness is one of many physical properties considered when selecting a material for a specific application.
Beware of some common misconceptions. Durometer hardness is often inaccurately confused with the properties described below.

11 Considerations When Selecting Thermal Interface Materials for Electric Vehicle Li-ion Battery
Currently, lithium-ion (li-ion) batteries are the most common type of battery used to power electric vehicles. Today's market is demanding that batteries charge faster and last longer. Because li-ion batteries produce significant heat when in use and charging, thermal management is critical. Excessive heat can cause irreparable damage to the battery.

Technological advances in properties of soft, flexible foam and elastomeric materials have continued. These thick, soft, flexible foams and elastomers like PORON foam, silicone foam, and more are ideal materials for sealing, gasketing and cushioning across many industries and applications.
They compress, form to irregular surfaces, bend, and flex within an application without damage or delamination, but from the perspective of the converter, these materials may also introduce challenges when trying to achieve the tight dimensional tolerances common in metal and plastic-molded parts.

Masking can seem like a "simple" process that is often accomplished with masking tape slit to common widths and applied by hand to protect surfaces from paint, contamination, or damage. Similar to surface protection tapes, masking materials are often discarded long before the final product reaches the customer. So what benefits are seen by changing from rolls of tape to die-cuts specific for your application?
