1. 金屬材料專業
其實熱處理和焊接這兩個專業都很好了，都很有前景，如果在這兩個里必須選擇一個的話，建議你選一個自己愛好的並能為之貢獻一生的方向。
2. 英文翻譯
Die Casting Die Casting materials used wood materials can be selected, Machinable plastic, aluminum, iron, steel and so on. Wood model is still widely used in hand-style one-piece or small batch proction, but with the requirements of environmental protection, and timber processing poor performance limitations, will be replaced by the EPC. EPC order for the foam sheet materials, rection of paste into shape, and then pouring from the casting, compared with the methods used wooden mold, short cycle, and low cost.
The application of plastic on the rise, especially plastic Machinable the increasingly wide range of applications. Light weight aluminum alloy die because of the higher dimensional accuracy, the wider application. However, the recent application of a downward trend, some of the cast iron and plastic has been replaced by model.
Mold is a large cast iron foundry of choice for the proction, use and a large number. It has a high intensity, high hardness, good processing, low-cost, long-life advantages. In recent years, e to the casting level, more and more like, bottom-mode, frame type, such as using higher strength and wear resistance of ctile iron or high-strength alloy cast iron proction, and heat fatigue The better performance of graphite cast iron have been used for the proction of hot-box material.In the past, steel, sand casting molds for the proction of standard parts and pieces of the structure, less casting molds for the proction of body, because life is not higher than that of carbon steel or low-alloy ctile iron gray cast iron, steel and very expensive. With the mold processing technology to improve the dimensional stability and mold on the request of the increased number of die steel, Cr-Mo alloy steel, such as H13 steel, have begun to be used to proce heat and mold-box body. In the die-casting molds in the lining of the main mode of early material used 3Cr2W8V, in recent years, more use of H13, Sweden, 8407, DIVER, such as hot die steel.Other parts of the die-casting mold materials are carbon steel, tool steel, some cast iron. Mold cavity of the significant improvements in materials, new types of steel will be some progress. Die-casting mold because of its harsh working conditions, higher material for the requirements of the world's developed countries to adopt high-quality H13 steel, foreign steel mold directly to high-quality H13 steel supply mole users, user-friendly not only to shorten the user mole Preparation cycle, but more importantly mole to ensure quality.As the China-made mole H13 material can not be guaranteed, the impact of mold proction, imports of steel H13 is much higher than the price of domestic steel, in order to rece the mold manufacturing costs, to be developed very high-quality die-casting molds made of steel.
3. D2是什麼鋼 有什麼 特性 做刀很好嗎
D2（Cr12mo1v1），優質工具鋼，硬度59-60HRC，深度冷處理至-120度，兩次退火，其優點是堅韌和較長時間的刀刃保持性。
作刀的效果很好。
