Laminating Metal Foils to High-Temperature Insulation

Posted by Brenda Doskocil on May 29, 2018 6:19:54 PM

Metal foils that are laminated to high-temperature insulation can increase the effectiveness of die cut heat shielding. Aluminum foils reflect radiant energy and reduce the amount of heat that high-temperature insulation must absorb. Metal foils also support micro-perforating and embossing (kalotte), value-added processes that reduce noise and support manufacturability.

Laminating metal foils to high-temperature insulation can also support thinner heat shield designs. For example, a foil-faced structure that’s just 1/8” thick can reduce temperatures from 1800° F to 200° F. These die cut products can fit into tight spaces, support vehicle lightweighting efforts, and meet precise dimensions. Foil-faced heat shields offer many advantages, but lamination can be challenging.

Micro-Perforating for Sound Absorption in Automotive Heat Shielding

Posted by Brenda Doskocil on May 15, 2018 2:07:32 PM

Micro-perforating for automotive heat shielding creates very small holes in aluminum foils. These holes or micro-perforations improve acoustical performance by absorbing noise across a specific frequency range. Heat shield micro-perforating also complements manufacturing processes such as embossing and lamination. For a complete heat management and NVH solution, micro-perforating adds value to automotive die cutting.

Aluminum foils that are micro-perforated also support vehicle lightweighting and can be formed into complex, three-dimensional shapes. Typically, these die cut heat shields are used in engine shields and underbody shield applications. Automotive applications include tunnel shields, inner and outer dash shields, and hood insulators for a cooler, quieter ride.

Embossing (Kalotte) for Automotive Heat Shields: Value-Added Die Cutting

Posted by Brenda Doskocil on May 9, 2018 8:26:48 PM

Embossing for automotive heat shields in NVH applications creates raised, three-dimensional features on aluminum foils. By adding a Z-axis to these flat, flexible substrates, embossing provides for better formability during product manufacturing. Embossing also provides benefits in terms of material thickness, structure, design, noise reduction and aesthetics

During the embossing process, aluminum foil is fed into an embossing machine that creates raised pebble features along the surface of the substrate. With heat shields, embossing also supports micro-perforation and lamination. These value-added solutions are part of what separates JBC Technologies from other automotive die cutters.

Die Cut Heat Shields for Thermal and Acoustical Insulation

Posted by Brenda Doskocil on Nov 9, 2017 7:03:54 PM

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.

Case Study: Die Cut Foils for Automotive Heat Shields

Posted by Brenda Doskocil on Mar 30, 2017 8:00:00 AM

Die cut foils are used in automotive heat shields to provide thermal and acoustical insulation. These formable, flexible, thin-gauge materials can be micro-perforated for noise reduction, and can be laminated to high-temperature insulation to create foil-faced structures that absorb high heat and reduce temperatures quickly. As this case study shows, JBC Technologies provides die cut aluminum foils that solve design challenges and meet multiple requirements.
