Electromagnetic interference (EMI) is a man-made or naturally-occurring phenomenon that disturbs electrical circuits and disrupts electronic devices. The causes of EMI are numerous, and include both ambient sources and power quality problems. The effects of EMI can range from data losses and decreased performance to system failure and loss of life. By protecting electronic devices and systems against electromagnetic noise or crosstalk, engineers can mitigate these risks.
Die cut heat shields protect the interiors of vehicles and equipment against excessive heat from engines and exhaust systems. Depending on their construction, these die cut products can also reduce unwanted sounds. For example, die cut heat shields with an aluminum foil facing can be micro-perforated for noise reduction and embossed for flexibility. This thin-gauge foil reflects radiant energy, and can be laminated to thermal insulation that absorbs high heat and reduces temperatures quickly.
Die cut weather seals protect interior components from water, light, dust, dirt, and other contaminants. They are used with automotive head lights and tail lights, furnace doors, HVAC access panels, cover plates, and lenses for LED lighting. To support cost-effective manufacturing, these die cut products are fabricated from sheet or roll materials and can attach to the substrate with metal fasteners or adhesives.
Die cut vibration isolators prevent vibrations from entering automotive interiors, machine components, and other engineered systems and spaces. In automotive designs, die cut gaskets for NVH and BSR are helping to meet consumer demand for quieter vehicles. Without adequate vibration control, the repetitive, oscillating motion of parts and surfaces can also induce fatigue and reduce reliability.
For automotive designers, die cut products for vibration isolation support perceptions of product quality. Engineers who design industrial equipment, HVAC systems, and electronics also need die cut gaskets such as isolation mounts and isolation pads. JBC Technologies can help you with material selection, and offers access to a strategic supplier network for microcellular urethanes and closed cell foams.
Die cut gaskets for noise, vibration and harshness (NVH) and buzz, squeak and rattle (BSR) support quieter vehicle interiors, stronger perceptions of quality, and increased customer satisfaction. Die cut NVH gaskets reduce or eliminate unwanted sounds (noise) that a vehicle’s occupants hear, the vibrations they feel, and subjective perceptions of harshness. Die cut BSR gaskets support the fit and wear of vehicle components that can rub together and produce sounds at audible frequencies that can be measured acoustically.
JBC Technologies is an automotive die cutter that helps design engineers reduce BSR and NVH. Depending on your application requirements, we can provide you with die cut gaskets that reduce the strength of sound at its source, or that interrupt the path of noise and vibration. We also supply die cut automotive gaskets that absorb noise or vibration energy. Selecting the right BSR and NVH material is just one of many challenges facing the design engineer, but choosing the right die cutter can strengthen vehicle designs.
