Double heat control for PLA pelletizing die.Since 2002, an unusual die has been pelletizing Pelletizing or pelletising is the process of compressed or molding of product into the shape of a pellet. A large range of different products are pelletized including chemicals, iron ore, animal compound feed, and more. PLA (Programmable Logic Array) A type of programmable logic chip (PLD) that contained arrays of programmable AND and OR gates. PLAs are no longer used. See PLD. (language, music) Pla - A high-level music programming language, written in SAIL. biopolymer bi·o·pol·y·mer n. A macromolecule, such as a protein or nucleic acid, that is formed in a living organism. biopolymer any protein or nucleic acid produced by a living organism. at NatureWorks LLC, Minnetonka, Minn. It was publically discussed for the first time by Coperion Werner & Pfleiderer, Ramsey, N.J., at PLASTICS TECHNOLOGY'S Bioplastics Processing Conference last month in Charlotte, N.C. The die has a heating channel between every row of die holes--instead of every two rows--for greater heat control. It also uses a rectangular heating slot to increase surface area and heating efficiency because PLA's viscosity is 50 times more temperature-sensitive than that of polyolefins, Coperion notes. Improved wear protection comes from brazing brazing, method of joining metal parts using nonferrous filler metals with high melting points such as copper, silver, and aluminum alloys. Brazing differs from soldering (see solder) by using a higher temperature; and unlike welding, the parts are not melted. the tungsten carbide die-hole cylinders to each other instead of to the chrome die surface. The latter creates a site for corrosion, Coperion says. Tel: (201) 327-6300 * www.coperion.com [ILLUSTRATION OMITTED] |
