l   Mesh Fix Wizard: The BLM mesh generator will monitor the mesh quality and alert its users if there is any mesh defect. In the past, these defects could only be manually fixed. Now, a Mesh Fix Wizard is available to offer a quick fix on mesh defects and ensures mesh quality for accurate mold-filling simulation results.

l   Efficient Solid Meshing for Complex Runners and Cooling Channels:  The recent development of BLM technology unleashes the limitation that users cannot directly import the the complete geometry of runner or cooling system from CAD into mold-filling software without any modifications. Now, a complete meshing for a complex runner or cooling channel design is possible. This improvement not only reduces the time for mesh preparation but also offers high accuracy for flow prediction of both melt and coolant.

l   Support Various Industry-specific Molding Processes :  The BLM technology can be applied in diverse molding processes, including multiple component molding (MCM), 3D cooling channel, compression molding, powder injection molding (PIM), MuCell®, gas-assisted injection molding, water-assisted injection molding, co-injection molding, and bi-injection molding.

In short, with the recent advancements in BLM mesh technology, the tasks and the time involved in a BLM mesh preparation has become greatly efficient. Also, the mesh quality has been strengthened to improve its functionality. Particularly, when meshing a complex geometry, using a BLM mesh is the most appropriate type of meshing that can fully capture its distinctive geometric characteristics; therefore, the accuracy of mold-filling analyses can be further ensured.
