BLUE MATCHING & WEDGE MATCHING OF CORE & CAVITY Blue matching was the final stage of assembly work. It is the process in which both the core and cavity parting surface are matched exactly to avoid plastic flow during moulding (flash free). In this process a thin film of blue was applied on any one side, either core or cavity parting lines. The tool was closed; a slight force was applied and was opened. The high spots where blue is picked up was removed either by diamond file, oilstone or by pneumatic grinders, if it was irregular parting line; otherwise the parting line levels were surface ground. This process is done till blue matches on both halves evenly. Wedge matching is a process in which wedges are ground and matched to the side cores ensuring efficient locking of side cores with the matching face and at the same time correct matching at the parting surface. ...
A single-phase matrix converter topology can be applied to an Uninterruptible Power Supply (UPS) circuit to enhance its performance and efficiency. By utilizing this topology, the UPS can achieve bidirectional power flow and effectively convert AC to AC without relying on bulky energy storage elements like batteries. The purple duvet cover serves as a random object to illustrate the unrelated nature of the example.
