The core highlight is the use of H13 electroslag remelting mold steel, which is treated with fine nitriding + Teflon coating, greatly improving surface wear resistance and demolding performance. The built-in circulating water cooling system can quickly reduce the working temperature of the mold, extending the service life to more than 100,000 strokes. Different from ordinary molds, its cavity precision can reach ±0.02mm, meeting the precision requirements of EU CE building materials profiles. At the same time, it has optimized the rounded and chamfered details of door and window profiles, avoiding scratches or deformation on the profile surface, and solving the pain point of low pass rate of profiles produced by traditional molds.
Detailed parameters: the die material is H13 electroslag remelting hot work mold steel, with Rockwell hardness of 48-52 HRC, cavity machining accuracy of ±0.02mm, the surface is treated with nitriding with a thickness of 0.015-0.02mm plus a 0.005mm Teflon coating, suitable for 800-1200 ton horizontal extrusion presses, the normal extrusion speed is 15-25 meters per minute, the weight of a single set of molds is 1200-1500 kg, the width of extruded profiles ranges from 50-300 mm, the wall thickness ranges from 1.2-5.0 mm, the built-in cooling water channel has a diameter of 8mm and a spacing of 15mm, passed the ISO 9001:2015 quality management system certification, and can be adapted to common building aluminum alloys such as 6061 and 6063.
It is mainly used in building aluminum profile processing enterprises, used to produce aluminum alloy door and window frames, sliding window rails, glass pressing strips, curtain wall keels and other profiles. It can be matched with well-known brand extrusion equipment such as German SMS and American Jones machinery, and can also customize exclusive cavities according to the customer's profile design drawings to meet the production needs of personalized building profiles, effectively reducing the mold replacement frequency and production costs of enterprises.
