Handle Door Lock
Aug 31, 2018


Handle door lock production process

The production process of the handle lock mainly includes stamping technology and die casting 

technology.


1.Stamping technology

Cold stamping is the main process for the production of handle locks. The above stamping process 

has achieved automatic continuous stamping in foreign countries. For example, the drawing parts 

adopt the multi-station automatic transmission punching punching, shallow drawing and bending, 

and the progressive pressing is adopted. Other companies use robots and multiple single-station 

presses to form an automated stamping line.


Regardless of the type of stamping, the production line consists of the unwinder, leveling machine, 

feeder and press. This method is more efficient than single punching, and has stable quality, less 

space and station equipment, and effective material utilization. High and no scratches on the 

workpiece. In this regard, there are still many manufacturers in China that have not been realized, 

resulting in high material consumption and high working hours.


2.Die casting technology

The handles, flower plates and complex-shaped parts of the high-end handle locks are die-cast in a 

hot chamber using zinc alloy materials. The surface quality, precision and efficiency of die castings 

are higher than those of cold chamber die casting. After the surface is coated, plated or 

electrophoreled, the workpiece has a luxurious, elegant and clear line. Hot chamber die casting can 

suppress parts with large projection area and only wall thickness, and the processing process is 

convenient for fully automatic production. Although several kinds of such equipment have been 

introduced in China, the results cannot be fully exerted due to the lack of mold manufacturing.
