Draft Angle Injection Molding
Time to read: 6 min Draft angle injection molding is about applying an angle or taper to the vertical faces of injection molded parts. Draft is measured in degrees and promotes smoother part ejections, decreased tooling wear, and shorter cooling times. The benefits of proper draft include fewer defects, faster cycles, and lower costs. Typically, designers apply draft angles of 1.5° to 2° degrees to injection molded parts at mold depths up to 2 inches. Applying a slight taper like this might seem simple enough, but you can’t add the same amount of draft to every part – and minimum and maximum draft angles for injection molding can vary considerably.…

Construction of super hydrophobic paper by modified nano-SiO2 hybrid medium fluoro-epoxy polymer and its properties
Researchers found that by using a modified nano-SiO2 hybrid medium in combination with a fluorepoxy polymer, a superhydrophobic coating can be created on paper that retains the original properties of the paper. Most of the super hydrophobic paper surfaces prepared at present will change the original properties of the paper and can not be used for oil-water separation continuously. There is not yet much systematic research on super hydrophobic modification of paper-based materials. The use of polymers and inorganic fillers for synergistic modification is also relatively rare. In this paper, fluorine-containing epoxy polymer P(GMA-r-DFMA) and KH550 modified nano-SiO2 were mixed to obtain an organic-inorganic hybrid super hydrophobic solution, which was…

Crystalline histidine application in aquaculture
Taurine is a β-amino acid containing a sulfonate instead of a carboxylic group in α-amino acids. It is vital for organ development and aging but not for protein synthesis. Taurine is needed for membrane stabilization, has cytoprotective and cell volume regulation effects, and maintains calcium homeostasis and signalling. Aquatic feeds for farmed fish and shrimp are mainly made from protein rich ingredients such as fish meal, poultry by-product meal, soybean meal concentrate, yeast protein, pea protein concentrate, corn gluten meal and wheat gluten meal. Historically fish meal has been the protein source of choice and currently there is no alternative to replace fish meal completely. It is probably since most…

Doozy Salts Frozen Berries Nic Salt
Description Doozy Salts Frozen Berries is a mixture of berries and crushed ice, combined together for a cool refreshing vape. Feel the icy chill washed away by a wave of sweet berries. Nic Salts are extracted directly from the natural tobacco leaf versus traditionally being made using a form of artificial nicotine called ‘free base’. Free base nicotine can be quite harsh on the throat and can cause discomfort for some vapers. Nic salts are absorbed to the body far quicker than standard E liquid, so it provides a much quicker hit to keep your nicotine cravings at bay. In addition to this, Nic salts take away that harsh throaty aftertaste as they stay smooth…

Artificial intelligence for digital printing with maximum gamut volume
In a new study, artificial intelligence approaches are applied to predict the performance of a paper to achieve the maximum colour gamut. The colour gamut of imaging media is significant for the reproduction of colour images because its magnitude directly affects the degree to which colours change during the printing process. Over the last few years, digital impression technology has started to play a substantial role in the printing industry. The colour gamut of electrophotographic digital printing depends on various parameters including the printer and toner, but especially the properties (whiteness, roughness, and gloss) of the paper, which influence the final printed colour gamut and replication quality. In a new…

Anisotropic dispersion promoting and passivation protecting on epoxy anticorrosive coatings
Researchers found that the addition of cardanol-modified Janus nanosheets with Zn2+ to epoxy anti-corrosion coatings significantly improves their mechanical properties and corrosion resistance Defects in the curing process of epoxy coatings tend to deteriorate the anticorrosion performance of the coatings. An important way to enhance the anticorrosion performance of epoxy coatings is to add flaky fillers. In this paper, anisotropic Janus nanosheets (JNs) were prepared and modified by cardanol (CA) and Zn2+. Then, the obtained CA@JNs@Zn2+ Janus composite nanosheets were introduced into epoxy coatings. When the content of CA@JNs@Zn2+ is 0.2 %, the mechanical properties and corrosion resistance of the coating were effectively improved. Event Tip: Anticorrosive Coatings What principles…
