Materials for Battery Solutions - PORON EVExtend®
Our valued material supplier, Rogers Corporation, has released PORON EVExtend® polyurethane foam material. This material is ideal for battery pads for EV/HEV li-ion pouch cell batteries. The EXExtend 4701-43HBF offers an increased flammability rating of HBF, or HF1 (product dependent).

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.

Why is it so important that plastic injection molding companies provide value added services and secondary manufacturing services to their customers after molding their parts?
The answer is easy! Many end-customers of plastic injection molders are looking for vendor consolidation and supply chain simplification. They want to cut out and skip steps in their supply chain, sequentially helping to reduce costs and save time.

In this newly released application story, a global designer and manufacturer of critical intercommunication devices experienced a gasket failure allowing moisture to leak and compromise the internal components of their console. It's remarkable the amount of damage a single drop of water can do. Moisture often contains impurities and minerals that remain even after the water evaporates. Between the moisture and these remaining elements, the contamination can cause short circuits, corrosion, and mechanical problems. A malfunctioning device leads to recalls, replacements, and eventually a poor reputation. The company in this story did NOT want to deal with any of this.
The intercom console product was intended to be used in medical office settings. Cleanliness and sanitary standards were very important for the high-touch surface of this device. The console was sprayed with liquid cleaners often. The console housing required a reliable sealing gasket to keep moisture out.
Die-Cut Solutions for Vibration Control: Damping vs Isolation

Just about everything that has been engineered is likely to experience vibration. Unfortunately, it has been proven that vibration can be responsible for causing extreme damage to some applications. The source of vibration can come from impact, internal motors or external sources.
When choosing a foam for a product design, one feature that should be considered is the compression set resistance of the foam. C-Set is one of the most important characteristics to consider, and this blog post answers three basic questions to explain why.

Die-cut Components for Medical Devices
We believe that true stories can tell you more than any marketing materials that we create. That is why we are sharing two new case studies in this blog post. Both case studies explore die-cut solutions that Marian provided to medical device companies. Quality and reliability are critical in this industry. Additionally, assembly efficiency and cost savings are important to the success of the business. In these case studies, you will see that Marian is well equipped and prepared to meet the stringent requirements demanded by the medical device industry. Enjoy!

Imagine going 65 mph in your vehicle while on a road trip. The road you are driving on is old, so your vehicle bobs up and down the many dips and divots, your speakers are loud and are causing your rearview mirror to vibrate, making it hard to see, and your moon roof has a roaring noise sneaking through the cracks.
These foul disturbances are examples of NVH, also known as Noise Vibration Harshness.
