Today's KNOWLEDGE Share Any surface particle on a molded part used to belong to the Fountain Flow free surface. Free surfaces for a visco-elastic material typically suffer from flow instabilities, and these end-up creating surface defects on your molded part. High front velocity and especially flow front acceleration/deceleration will trigger flow instabilities and defects. This is why the gate area and the end of flow (see picture) are so prone to surface defects. We do have the highest velocity at the gate and a potential extreme velocity at the end of flow (or slowdown due to switchover). "Tiger Stripes" are a well known defect due to Fountain Flow instabilities triggered by a change of flowfront speed. source:Vito leo

Today's KNOWLEDGE Share A fully recycled composite bicycle bottle cage! Swancor and the Taiwanese brand Massload have jointly developed bicycle parts, a bicycle bottle cage highlighted in particular, crafted entirely from recycled composite materials." "The low-carbon bottle cage, which weighs only 17 grams, has undergone a year of rigorous testing and validation. It blends 50% of Swancor’s recycled carbon fiber with 50% recycled polyamide 6 (PA6) pellets, manufactured through an injection process. The companies anticipate commencing mass production of this environmentally friendly solution in the first quarter of 2024, with help from Massload, which has extensive know-how in supplying components to global bicycle brands." "Swancor’s own expertise has contributed to the bicycle bottle cage’s development. The company has been actively promoting the use of recycled materials, alongside the development of its recyclable thermosetting resin EzCiclo and CleaVER degra

Toyo Ink India, a member of the Japan-based chemicals manufacturer artience group (formerly Toyo Ink Group), announces plans to expand its production capacity for solvent-based adhesives at its manufacturing site in Gujarat, India. Meet Market Demands: A new production facility will be built on-site at the Gujarat plant as part of the expansion to meet rising local demand. The plant is slated to begin operations in April 2026 and will help to boost the Gujarat site’s adhesive capacity by 3.5 times its current output. In 2014, Toyo Ink India began importing adhesives from Japan and selling them to the local market for automotive interiors and has over the years expanded applications to home appliances and labels. In December 2021, a production operation was established in India, Gujarat, enabling the company to more promptly respond to customer needs and to further grow its business. As demand from these markets grew, the capacity for adhesive production became tight, leading to the dec

Orion broke ground on a plant in Texas that will be the only facility in the U.S. producing acetylene-based conductive additives. These additives will be for lithium-ion batteries and other applications vital for the global shift to electrification. Producing Additives having One-tenth of Carbon Footprint: The site in the city of La Porte, southeast of Houston, will create many high-skilled jobs, both in construction and technical fields and bring innovative technology to the American economy. The battery additives produced by Orion’s plant will be super clean, with only one-tenth of the carbon footprint of other commonly used materials. “Orion is already the sole producer of acetylene-based conductive additives in Europe,” Orion CEO Corning Painter said at the groundbreaking ceremony. “Our plant in La Porte will be a pivotal step toward strengthening the regional supply of conductive additives in the rapidly growing U.S. battery market.” Every battery requires conductive additives. Th

This is an amazing first step to make hydrogen fuel from greener sources which paves way for a sustainable future! source:Brendan Rogers

Today's KNOWLEDGE Share Characterizing the excited states of individual atoms through the combination of tunneling microscopy and pulsed laser The characterization of the dynamics of the excited states of a single atom localized on a surface remains to this day an experimental challenge. By combining a tunable pulsed laser at the junction of a low-temperature tunneling microscope, researchers have highlighted rapid photocurrent signals that can be attributed to the dynamics of excited states of an individual erbium atom deposited on the silicon surface. In a vast majority of physico-chemical processes, the excited states of atoms are obtained either by absorbing light or by interacting with electrons. The most common method for measuring the characteristics of the quantum state of an excited atom is to analyze the light emitted during its relaxation to its ground state. In a gas, it is possible to observe many atoms relaxing simultaneously and thus collect enough light signal. Whe

Today's KNOWLEDGE Share Full carbon fiber composite fairing delivered for first flight of Tianbing Technology’s Tianlong 3  The large-diameter full carbon fiber composite fairing of Tianbing Technology’s Tianlong 3 (TL-3) launch vehicle rolled off the production line. “Tianbing Technology has fully mastered the development capabilities of large-scale composite cabin sections and achieves another major breakthrough in the development of high-quality, high-efficiency, low-cost products. The rocket fairing is located at the front end of the rocket and is an extremely important and complex section of the rocket. The TL-3 large fairing has a diameter of 4200 mm and a length of about 13 meters. It is made entirely of carbon fiber composite materials. It is the largest fairing in domestic commercial aerospace and the largest full carbon fiber fairing in China. It is also the first domestic fairing that is customized for satellite internet constellations. It can be called the most advanced
