Thermoplastic, Heat Seal and Hot Melt Adhesives are redefining cut and sew solutions for the textile industry. This new technology replaces the need for stitching in a wide range of garments and soft goods, allowing manufactures to redesign their processes to increase quality and production.
Providing an ideal bonding solution for fabrics, heat seal tapes are offering manufacturers advantages such as high bonding strength, flexibility, durability, and solvent resistance. Heat seal thermoplastic adhesive tapes offer the additional advantage of being repositionable. When the thermoplastic adhesive is heated, it is soft and malleable. It becomes rigid as it cools, but with heat it can be reactivated.
As the automotive industry moves toward lighter weight materials and multi-component assemblies, mechanical vibration has been identified as a potential noise problem in auto interiors. The specific issue lies in the vibration energy that is generated, and travels throughout the automotive structure.
There are several ways to mitigate vibration sound issues. Prevention of the vibration at its source is one solution. The introduction of a low friction surface will prevent contact between assembly components. Altering the vibration mode of the structure can also be effective. This is done by attaching a dampening material in order to dissipate the vibration. Another approach involves isolating the vibration moving from one area to an adjacent area by way of isolators. Used to separate components of a structure, isolators effectively prevent vibration from spreading to surrounding areas.
Can-Do serves the automotive industry with a variety of adhesive tape products that mitigate sound vibration issues. A variety of 3M products are available to prevent vibration issues and Can-Do has the converting capabilities to transform these products into custom solutions.
Automobile assemblies today utilize a wide variety of adhesive materials in numerous applications: seats and linings, headers, dashboards, exterior emblems, and more. The effort to lower vehicle weights and therefore improve fuel efficiency has resulted in the use of many new materials such as lightweight metals, plastics, textiles, and foams. In order to be considered for the manufacturing of vehicles, these materials must comply with strict safety standards. The National Highway Traffic Safety Administration (NHTSA) mandates that materials exposed to the air in a vehicle passenger compartment must pass the flame spread test in FMVSS (Federal Motor Vehicle Safety Standard) 302.
Lean manufacturing, together with the trend toward the design and manufacture of lighter weight vehicles, has required designers and engineers to seek out and find new materials and applications to solve design challenges in the auto manufacturing industry. Adhesive tapes can and do provide highly effective and efficient bonding solutions for auto assembly processes.
Corporate Average Fuel Economy (CAFE) standards was established and enacted by Congress in 1975 to reduce energy consumption and increase the fuel economy of cars and light trucks. The National Highway Traffic Safety Administration (NHTSA) plans to raise standards, which will expand CAFE levels over the next several years. The legislation is intended to strengthen our nation’s energy security and save consumers money when they fuel up.
We live in an increasingly noisy world. Besides the obvious effects on hearing loss, excessive noise levels contribute to hypertension, high-stress, tinnitus, and sleep disturbances. Modern transportation methods, especially aircraft, are on a mission to quiet the noise. In addition to the roar of the jet engines, other sources of noise in the aircraft cabin include the air conditioning system, peripheral equipment, vibration, as well as the inevitable wind noise. The noise level in the aircraft cabin at takeoff and landing can reach as high as 105 decibels (dB) and 85dB at cruising altitudes. Noise levels higher than 90 dB, maintained for eight hours or more can cause permanent hearing loss, not to mention being a major source of stress in an environment where creating and maintaining a calm environment is paramount not only to passenger satisfaction, but also to flight safety. It is no wonder that noise abatement is a growing area of focus and concern in the manufacture of modern aircraft.
Aerospace manufacturers, like manufacturers in most industries, are under pressure to increase profitability and reduce the cost of doing business. Aerospace OEM and MRO companies have the added challenge of remaining compliant with FAA regulations and ISO certification requirements.
