This Asthma Group Suggests Making Your Own Spacer With A Plastic Bottle

For one thing, it’s linked to a variety of factors, including air pollution, smoking, and insufficient medical care, that are more severe in poorer countries. The effects can be seen in mortality rates. According to the Global Asthma Network, age-standardized asthma mortality is highest in Fiji, the Philippines, and South Africa. (However, there are data gaps in a number of countries, especially if asthma isn’t recorded as a cause of death.) While asthma deaths are low overall, these are preventable. One reason people, mainly older adults, are still dying of asthma is that in resource-strapped places, it’s hard to access preventers. So these medical systems are likely to focus on relievers instead. Thus, in low-income countries, according to the Global Asthma Report 2018, “the huge majority of asthma patients are being treated only on an emergency basis.” At that point it may already be too late. One policy implication is that preventive medicines and care should be provided for free or at subsidized rates to affected people who couldn’t otherwise afford them. But while asthma inhalers themselves are complicated to manufacture, and heavily marketed, one accessory doesn’t need t...

Ever wondered what blow molding is? Here’s a quick-fire overview of the manufacturing process, including its advantages, disadvantages, and application areas. Blow molding is a plastics manufacturing process used mainly to manufacture hollow parts and products from a wide range of thermoplastics. The process is named the way it is because it involves blowing air into molten plastic almost like a balloon until it fills the cavity of a mold tool. There are three main types: extrusion, injection, and injection stretch. All input materials are thermoplastics, and many are similar to those used in injection molding, such as POM, ABS, polystyrene, and polycarbonate among others. The blow molding process has been around for thousands of years and remains essentially unchanged. The main difference with the modern process is that it’s heavily automated. The general process for extrusion blow molding is as follows: In the case of injection and injection stretch blow molding, the parison is replaced with a preform, which is produced through injection molding. The associated tools are often made from aluminum or steel and are great for thousands of parts. Naturally, not all plastic p...
