Impact extrusion process of coloring is mainly mold design, extrusion temperature, extrusion speed, cooling methods for pattern aluminum surface state and organizational uniformity. Mold design should allow sufficient feed blend, or prone to bright (dark) with defects may appear on a tread separations with aluminum; at the same time, the mold surface condition and pattern aluminum extrusion profile also affect coloring . Extrusion temperature, speed, cooling and cooling time Jinan five different checkered stock, so that type of tissue heterogeneity fifteen pattern aluminum diamond plate, will produce a different color according to the aluminum content of alloying elements can be divided into eight series were 1 * ** 2 *** Shandong five checkered stock manufacturers, 3 *** 4 *** 5 *** 6 *** 7 *** 8 *** 1-8 series aluminum use Introduction: 3 ××× series of aluminum plates 3 ××× series aluminum sheet: representative 3003,3004, 3A21 based. Also known as rust-proof aluminum. Our 3 ××× series aluminum production process is more outstanding. 3 ××× series aluminum is made of manganese as the main ingredient manufacturers Which five checkered stock, content between 1.0-1.5%. Is a series of anti-rust function better. Routine use in air conditioners, refrigerators, cars and other wet environments, the price is higher than 1 ××× series, is a more commonly used alloy series. Jinan five checkered stock, aluminum rolls, five checkered provided by Jinan Heshun Aluminum 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.
