Plastic extrusion is a continuous high volume manufacturing process in which a thermoplastic material is homogeneously melted and then forced out of the shaping die by means of pressure. There are different types of an extruder. Generally, extruders can be classified as continuous or discontinuous ext...
The needles are generally made of a heat-treatable stainless steel or carbon steel. To prevent corrosion, many are nickel plated. Depending on the style of device used, the main body of the tube can be made of plastic, glass, or both. Plastics are also used to make the plunger handle ...
A growing trend in plastic bottle manufacturing is to seek non-petroleum sources, the most popular of which is polylactic acid (PLA). Plastics manufactured using plants are biodegradable and compostable, and therefore cause less environmental impact if they wind up in a landfill or the ocean. ...
Quality control technicians are responsible for ensuring that food products meet industry standards and regulations. They monitor the production process to ensure that products are manufactured according to specifications and conduct quality tests to detect any defects or contamination. Quality control techn...
At that time, casein glues made of milk and nitrocellulose glues were first manufactured. In the 1930s, advances in the chemical and plastics industries led to development of a wide range of materials called adhesives and plastic or synthetic resin glues. World War II led to a further ...
Chapter Three - What types of plastics are used to produce 55-gallon plastic drums? Among the various materials used in product manufacturing, plastics are the most versatile and widely utilized, catering to both industrial and domestic applications. The robustness, strength, and adaptability of plas...
Bio-based materials:Bio-based materials, such as cellulose nanofibers and lignin, are being explored as potential alternatives to traditional materials, such as petroleum-based plastics. Energy Efficiency:The focus on energy efficiency continues to be a key trend in the paper manufacturing process, wi...
Like most types of plastics, polypro is made from substances that are derived from hydrocarbon fuels like petroleum oil. First, the monomer propylene is extracted from crude oil in gas form, and this monomer is then subjected to a process called chain-growth polymerization to create the polymer...
3. Drive operational resiliency The complexity of many industrial businesses means there are many potential avenues for increasing resiliency. They may include avoiding single sources of supply, increasing sustainability and circularity, establishing their own renewable power generation infrast...
