First, it should be noted in the production process: choose the width, the thickness of the film medium; the aluminum complex cross-sectional shape, looks to the wide and narrow the disparity is large, easy to fly side blows, reducing foil cover ability, affect the quality of spraying another. We should also pay attention to: the timely spraying film after film after Jinan profiles Supplying aluminum mold, the mold should be sprayed Shandong Supplying aluminum prices, parking time is as short as possible in order to ensure the quality of film and painting, general film after parking time. Do not exceed 16h 1, ××× series aluminum alloy: 3003 on behalf of aluminum, 3004 aluminum, 3A21 aluminum based. 3 ××× series aluminum is the main component of manganese content between 1.0-1.5%. Is a series of anti-rust function better. Routinely die in air conditioners, refrigerators, cars and other wet environments aluminum price is higher than 1 ××× series, is a more commonly used alloy series. 2, ××× series aluminum alloy: representative of 4A01. Aluminum manufacturers tell us that belong to a series of high silicon content. Usually silicon content of 4.5-6.0%. Genus aluminum mold construction materials Jinan direct prices, mechanical parts, forging materials, welding materials; low melting point, good corrosion resistance. Direct mold aluminum, aluminum molds, rolls supplied by Alcoa Aluminum Co., Ltd. Jinan rolls. Jinan Heshun Aluminum Co. (www.jnhsly.com) strong, credible, in Jinan, Shandong aluminum products industry has accumulated a large number of loyal customers.
