Lock parts investment casting process. from jaiachuancasting's blog

Lock parts castings, door and window components are the most commonly used casting products in the construction industry, including locks, locks, hinges, handles, etc. These locks are usually small in size, weighing between 10 and 250g, very precise in size, with high tolerance requirements, important linear dimensional tolerances are usually +/-0.15mm, for critical areas, tolerances can be +/-0.03mm, The surface finish in the visible area must be very smooth. Locks can be produced by several different production methods such as zinc die casting, fusion film casting, MM, etc., but only investment casting can provide the best mechanical properties and the best price/performance ratio, and provide the best safety performance and longest Service life The life of doors and windows.

Door and window locks are assembled from multiple lock pieces, so the dimensional tolerance and mechanical strength of the parts are particularly important for the smooth function and safety of the lock.
