When it comes to determining how well an aircraft will perform, the thrust-to-weight ratio is one of the most important metrics. Aerospace manufacturers have always aimed to keep this ratio as low as possible by creating lighter aircraft, but the metals traditionally used in aircraft bodies are heavy. Composite materials, on the other hand, are lighter and enable manufacturers to create more fuel-efficient aircraft when mixed with metal. Let’s examine the history of composites in the aerospace industry and where future innovation is headed.
Porous plastic foam is on the cutting edge of insulation for heat, vapor, noise, and other elements. The two major variants of porous plastic foams are open and closed cell foams. Both types of foam are used in everyday products, but because of their structural differences, one type of foam may perform better than the other depending on the desired application.
Vibration isolation is an integral part of any engineering project and design. Experienced manufacturers know that stopping excessive vibration is necessary, or else it can cause wasted energy and damaged equipment, leading to broken products, expensive repairs, and reduced profits. Original equipment manufacturers need to be able to trust the reliability of the anti-vibration mounts they install or else they could wind up with subpar products and unhappy customers.
Melamine foam is an effective absorber suitable for applications involving noise control and thermal management. Polymer Technologies provides a range of melamine foam insulation for a variety of industries, mainly power generation, construction, rail transportation, heavy truck, aerospace, medical, and marine manufacturing. The foam is widely used because it is a versatile, flame resistant material that is lightweight, semi-rigid yet flexible, and easy to customize. This allows manufacturers to save production time and labor costs during installation.
Engineers are always looking for more ways to implement new technologies in their machinery. Over the past decade, the drive to create more versatile machinery has only continued to increase. With the amount of power and technology being put into these machines, the need for greater insulation and noise reduction solutions has become apparent. When keeping up with the need to improve machinery, it's important to keep the health and safety of the operator in mind. There are a number of factors driving the trend for machine versatility. Here are 3 of the most significant:
Topics: product development
When engineers are developing products that require a polymer solution—albeit rubber, insulation, or other material—deciding exactly which materials to use and finding a supplier is an integral part of the product development process. Performance of those materials is not the only concern, either: chances are you’re working within budget and time constraints and need to have expectations clearly defined. In addition to providing materials or a manufactured component, a good supplier is also your partner. Here are some questions you might have during the product development stage that an experienced supplier can address.
Damping is one of the most effective methods of controlling noise and vibration. It is a process that converts vibrational energy into heat, eliminating the vibrational energy through friction and other processes. Increasing damping or stiffness can both reduce resonant vibration and the resulting noise by preventing the vibration from travelling through the structure.
What is overmolding?
Overmolding is the process of using a foam application to mold over a tube, pipe, or piece of metal. The process has the capability to change the aesthetics and performance of a piece of equipment. While its primary application is to provide a clean, textured finish to an application, overmolding can also be used to address heat and noise concerns that may come up. The versatility and range of applications make the overmolding process a vital part of the manufacturing process. Though it is a relatively common process (for example, you may see overmolding on the handles of a pair of pliers), overmolding has many applications that are more complex and demanding.
What is RoHS Compliance?
RoHS, which stands for the Restriction of Hazardous Substances Directive, is a European Union directive restricting the use of specific hazardous substances in certain electronic and electrical equipment. These substances are considered hazardous to the environment and are particularly dangerous in terms of occupational exposure during the manufacture and recycling stages of equipment. With its implementation on July 1, 2006, the directive restricts the use of the use of the following substances:
A lot of effort goes into creating any kind of medical device, and the approval process is often long. Naturally, a significant part of a manufacturer’s focus is on making sure the device works and complies with safety standards. However, comfort should also be at the top of your list of concerns when designing devices that enable patients to monitor and maintain their health. If a product is made for home use, part of its effectiveness is ensuring that patients will actually use it, and if they find it cumbersome and inconvenient, they may not.
