Description

technical field

[0001] The invention relates to a method for manufacturing a lock, in particular to a method for manufacturing shaft parts in a special lock for containers. Background technique

[0002] With the development of international trade, the demand for containers is very large, and the corresponding demand for container locks is also increasing. However, as the shaft parts with the greatest force and the highest strength requirements in container locks, the process of forging and reprocessing is still used for many times. Due to the large number of processes and heavy workload, it is relatively difficult to carry out mass production. Resulting in high product costs.

[0003] Investment casting is also known as "lost wax casting". This method is to inject the fusible molding material into the mold (in the mold) to make a investment mold, assemble it into a module, and then apply a liquid paint made of refractory material and binder on the surface of the module, an...
