Tacky glue is a very thick PVA, or polyvinyl acetate glue, used to adhere items that would slip away with thinner glues such as school glue. It dries clear and flexible.
Die casting is a high pressure metal casting process that forces molten metal into a mold. It produces dimensionally accurate precision metal parts with a high quality finish. Its ability to produce detailed parts makes it perfect for the mass production of products. Die castings are made from non-ferrous metals such as zinc, copper, aluminumTentang Die Casting. Die Casting adalah cetakan logam yang terdiri dari beberapa bagian yang bahannya terbuat dari baja (Hot Working Steel). Sifat dasar meterial Die Casting berupa mampu tarik panas (hot yield strength), ketahanan terhadap proses tempering (temper resistant), koefisien muai panas (thermal expention coefficient), konduktivitas The element aluminum (Al) has a specific gravity of 2.7, placing it among the light-weight structural metals. It is used as a base for die casting alloys with three primary constituents: silicon, copper and magnesium. Eight available aluminum die casting alloys give the designer the widest choice among the four primary alloy groups, and they die-casting, forming metal objects by injecting molten metal under pressure into dies, or molds. An early and important use of the technique was in the Mergenthaler Linotype machine (1884) to give line-long combinations of letters, but the appearance of the mass-production automobile assembly line gave die-casting its real impetus. 1. Die Casting. Die casting is the most popular aluminum casting process for casting aluminum parts. There are two processes: low-pressure die casting and high-pressure die casting, with the latter being the most suitable for the material. 3Hn6.
