Although the outer skin can be reground Alice in testing, when the outside can also cause severe warping the entire root steel scrap. Shortage capillary tube is then cut through the wall to get semi-finished steel, the quality control unit is Accel hardest and most important part. Accel unit production of steel is the most obvious sign of an internal thread phenomenon, through barren rolling three-roll rolling machine whose inner wall of the tube after rolling can not eliminate the presence of traces of that thread. When the thick-walled pipe thread rolling problem is not obvious when the thin-walled tube rolling thread if improperly adjusted phenomenon will be very obvious, and will lead to uneven thickness of the final product exceeded, the wall thickness of the local area and even lead to excessive that become scrap steel pipe.
Another factor affecting the quality of the mother pipe surface of the mandrel is the quality of the situation. Mandrel is rolling machine rolling tube-shaped tool in the table, determine the quality of the inner surface of blank pipe and the inner surface of the tube in the subsequent shortage of quality inspection can only be checked, but not grinding, can easily lead to the entire root of steel scrap judgment. Effect of the mother pipe is a factor in the quality of the final roll rolls have a certain life, when the roll wear to a certain extent, will lead to the production of severe shortage pipe thread appears, and poor ultra thickness requires adjustment or replacement in time roll, if you continue to use worn roll will result in serious quantities of product quality issues.The constant temperature mold of molding plastic parts with high precision contours is of significance in determining not only the productivity of the injection molding process but also the product quality. A solution to this challenge is the rapid thermal response molding process in which uniform temperature overall the mold part Wholesale Ice scarf ensures the product quality by preventing differential shrinkage, internal stress and mold release problems (Li, 2001). Many Computer-Aided-Engineering (CAE) and optimization methods have been carried out to observe and fine-tune the influences of the thermal system (Park et al., 1998). The results of these research works are obtained by using thermal analysis modules of commercial CAE packages such as C-Mold or Moldflow which are based on the initial designs generated by the human.
By given an initial thermal configuration design, efficiency and quality of the molded part can be predicted before an actual plastic mold is manufactured. One more necessary step for the complete automation in the molding thermal system is to generate the initial design for the conformal cooling channels.For example casting mould,mold making,plastic injection mold etc. In this paper, a featured-based approach to this problem is proposed. Super-quadrics is presented as a tool for recognizing the plastic part shapes and an algorithm is applied for generating the center line of the thermal sub-system of each individual surface. Finally, these sub sets of center lines are combined to create a unique center line which is the guide line for generating the cooling channel of the thermal system.Conformal cooling channel, as the name implies, refers to the channels that conform to the surface of the mould cavity. Conformal cooling channels have demonstrated simultaneous improvement in production rate and part quality as compared with conventional production tools.
