Standards for mirror polishing of molds, methods and precautions for mold polishing

Standards for mirror polishing of molds, methods and precautions for mold polishing

To avoid scratching and burning the surface of the workpiece, special care must be taken when polishing with # 1200 and # 1500 sandpaper. Therefore, it is necessary to load a light load and use a two-step polishing method to polish the surface. When polishing with each type of sandpaper, polishing should be carried out twice in two different directions, with each rotation of 45 ° -90 ° between the two directions.

Steel and Heat Treatment for Hot Extrusion Dies and Medium and Small Machine Forging Dies

Steel and Heat Treatment for Hot Extrusion Dies and Medium and Small Machine Forging Dies

When the hot extrusion die is working, it is subjected to compressive stress, bending stress, and tensile stress during demolding. The impact load received is smaller than that of a hammer forging die, but the contact time with hot metal is longer than that of a hammer forging die. The working temperature is higher than that of a hammer forging die, and the temperature rise varies when squeezing different metals, with a maximum of 800-85090. The thermal stress caused by rapid cooling and heating is also greater than that of hammer forging dies, and the friction is also more severe. The main failure forms of hot extrusion molds are excessive plastic deformation in the mold cavity, fatigue damage, thermal wear, and surface oxidation corrosion caused by repeated heating and cooling.

Large die-casting molds are key technologies for achieving integrated die-casting

Large die-casting molds are key technologies for achieving integrated die-casting

Abstract: Benefiting from the application of integrated die-casting technology in new energy vehicles, it has brought vitality to the manufacturing of large die-casting molds. The manufacturing of large die-casting molds has technical barriers and is a key technology to achieve integrated die-casting. This article introduces the role and application effects of large die-casting molds in integrated die-casting, discusses the manufacturing difficulties of large die-casting molds, the need to pay attention to mold material selection and mold design simulation applications, focuses on describing the requirements for temperature field thermal balance of large die-casting molds, and proposes measures to assist in thermal balance adoption. The application of in mold sensors is forward-looking. With the technological progress, the technical barriers of large die-casting dies have been gradually solved and mastered, opening up a new Xintiandi for the manufacturing of large die-casting dies, and promoting the development of new energy vehicles towards energy conservation and emission reduction.

The 2023 Foshan Casting, Forging, and Heat Treatment Exhibition will be held on June 15th

Due to the pandemic and changes in the international trade situation, the manufacturing supply chain has undergone new adjustments and changes. The country has introduced policies such as "new infrastructure" and "dual circulation" to promote the recovery of the manufacturing industry. In the context of declining overseas supply capacity and favorable domestic policies, high-end manufacturing has more upward cycle characteristics, activating the domestic demand market in the manufacturing industry, and promoting consumption upgrading has become one of the important ways for the rise of the Chinese manufacturing market, A batch of new formats and models have emerged, fundamentally subverting traditional work, production, and future business models. Artificial intelligence, Industry 4.0 solutions, and workshop digital twins are becoming increasingly important in the future industrial development.
