In a mold shop, workstations carry CAD, CAM, and CAE software that already push system resources to the limit. Many technicians once installed LuDaShi (Master Lu) to monitor temperatures or run benchmarks. After July 2016, when 360 acquired it, the tool gradually became bloatware—pop-ups, bundled installs, and background CPU consumption that slowed down UG, ProE, and PowerMill. Worse, uninstalling it often left behind several DLL files in the install directory that could not be deleted manually because they were locked by the system. This is similar to a seized insert during mold assembly: brute force fails, you need the right method.

To fully remove LuDaShi, skip its own uninstaller. Go to Control Panel, uninstall it there, then reboot into Safe Mode. In Safe Mode, delete the C:\Program Files (x86)\LuDaShi folder, plus LuDaShi folders under C:\Users\YourUsername\AppData\Roaming and Local. Those stubborn DLLs are usually driver-level leftovers; use Huorong or 360's "File Shredder" with "prevent recovery" checked to force-delete them. Important: close all mold design software first to avoid deleting shared library files by mistake. After cleanup, run CCleaner to scan the registry for LuDaShi keys, then check system services and disable items like "LuDaShi Service."

For mold shop technicians, system stability matters far more than benchmark scores. One of our shop's workstations suffered frequent stuttering during PowerMill post-processing because LuDaShi was updating in the background; after cleanup, toolpath calculation speed returned to normal. Remember: mold programming is most vulnerable to system interference—any unnecessary background process is a risk. Also, stop using LuDaShi to monitor hardware temperatures. Mold shops are dusty, and clogged heatsinks are common. Instead of relying on software alarms, blow out fans regularly with an air gun. For accurate temperature readings, check the BIOS. Keep the system clean and let the PC focus on running toolpaths—that is the maintenance habit a moldmaker should have. For more mold sourcing and technical resources, visit MoldWorld at www.moldw.com.
