Characteristics of an aluminum coil, compactness: the unique grain refinement process to ensure, no sand holes trachoma, stripes, bubbles and impurities 2 crack cracks and other undesirable phenomena, stress: the perfect pre-stretching Process and completely eliminate stress, in the process easy and stress warping, cracking and deformation of three, tolerance precision: All products meet the American Society for Testing and Materials (ASTM) and aerospace material specification (AMS) specification 4, workability : chemical composition, strength and hardness deviation minimize mold aluminum factory in Shandong, processing eliminate the occurrence of "sticky knife" "chipping" and other bad now 5, uniformity: heat treatment technology excellence, product 300MM thickness (or diameter) below, strength, hardness remained the same 6 Stability: All computer-controlled production processes, with little human error 7, dyed effect: uniform and shiny surface without streaks no blotchy or 8 different colors and other phenomena occur, anti- Corrosion of metals and alloys by microscopic examination Jinan mold aluminum manufacturers, with excellent resistance to stress corrosion and anti-spalling resistance, in a variety of media (such as water vapor and other weak acid weak base) environment does not produce long-term use of pits or hair Black phenomenon 9, resistance to high temperature: permanent deformation does not occur at 400 degrees Celsius aluminum quality work environment to identify what methods.? Identification of the surface coating film is good or bad way to compare aluminum front cover is to look at the edge of the aluminum buckle, see if I can expose them to film. Qualified Lvkou composite film at high temperatures up aluminum mold, exposing not down Jinan aluminum mold manufacturer, can certainly be peeled off the adhesive, and can not be purchased. Also known as a lot of their sales will be imported film coated aluminum, in fact, the difference between the so-called aluminum once imported and domestic film membrane installed fundamental rarely move, and hanging on the roof, there is unlikely to see out of. So absolutely no need to care about is not imported films, just to get a few sample compare to light, choose a good gloss on it. Shandong Aluminum mold aluminum manufacturers _ cis (certified) _ aluminum mold provided by Jinan Heshun Aluminium Limited. Jinan Heshun Aluminum Co. (www.jnhsly.com) Shandong Jinan, aluminum products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Aluminum leadership in cis with the staff warmly welcome all inquiries negotiations to create a better future for aluminum rolls.
