Is the difference between metal stamping parts and? Castings What?
metal stamping parts and castings the difference between We distinguish between the two? Aspects of processing technology and hardness testing. P Casting: with a. "Variety of casting method to obtain the metal forming objects, namely smelted liquid metal by pouring, injection inhalation, or other casting method into the pre prepared mold, cooling after falling sand and clean, up after treatment, the obtained a certain shape, size and performance of the objects. Hardware stamping parts < p > processing: < 1 With, thin, uniform, light, strong press features of other methods is difficult to manufacture with reinforcing rib, rib UPS, and downs or flange of the workpiece and to improve its rigidity. < p > 2 Due to the adoption of preci Sion mold workpiece accuracy can reach micron level and heavy stamping parts and castings distinction: a thin, uniform, light, strong press features of other methods is difficult to manufacture with reinforcing rib, rib UPS, and downs or flange of the workpiece and to improve its rigidity. Due to < p > 3 the adoption of precision mold workpiece accuracy can reach micron level and high repeat accuracy, specifications can punch a hole nest and the boss.
Stamping parts < p > 2 of the hardness testing: metal stamping parts of hardness testing by Rockwell hardness. Small, with complex shape stamping parts, can be used to test the plane is very small, can not be detected on the ordinary table.
casting hardness testing: th Properties of e the casting itself directly affect the quality of the processing which is an important indicator of the hardness of the casting processing.
