Methods of Processing Plastics,erally true to say that simple basic machines are used for this type of purpose and that there are no special or close temperature, pressure or time limits. The usual pressures lie in the region of 300–600 × 10. N/m. and the temperatures about 160–190°C. Since this branch of engineering is well estaCollected 发表于 2025-3-24 01:33:59
Methods of Processing Glass,is made plastic and heated above its transition point, while in the stock removing methods particles of glass are broken off with the material in the cold state. There are, in addition, various bonding methods which may be divided into three groups, viz: adhesive bonding in the plastic state, i.e. fperpetual 发表于 2025-3-24 03:26:46

Methods of Processing Monocrystalline Materials,he material forms a crystal in itself. Here, there are no intercrystalline interfaces, with the smaller crystals in an arbitrary arrangement. As a whole, therefore, the single crystal has a given orientation, meaning that the main axes assume a definite position in the piece of material. The physica灾祸 发表于 2025-3-24 13:45:01
