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.
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 aircrafts, 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 aircrafts when mixed with metal. Let’s examine the history of composites in the aerospace industry and where future innovation is headed.
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.
UL 94 is a plastics flammability standard, also known as the Standard of Flammability of Plastic Materials for Parts. This standard was released by Underwriters Laboratories (UL) to classify plastics based on how they burn, with orientation and thickness level determining a plastic’s tendency to extinguish or spread the flame once ignited, and how well the material resists ignition.
The AS9100 Quality Management System (QMS) belongs to a family of standards designed to address diverse quality requirements while also reducing supply chain costs throughout the international aerospace industry. Products such as insulation materials bring a high level of quality and trust when backed by a business with AS9100 certification.
Noise and vibration production is a major problem encountered by companies that utilize appliances in their workspaces. Appliances that produce significant vibrations can include any and all products with mechanical parts—generators, kitchen appliances like blenders, offices appliances like printers, and so on. Vibration is distracting, uncomfortable, and in some cases, unsafe for workers. It is one of the most common reasons companies will come back to manufacturers with complaints or request changes to the design.
