According to the artwork of a firm order, mold design team will build up 3D models with computer for further checking with design & technical departments, then the mold engraving department will make the dies with CNC, EDM or etching. After trial die casting with final adjustments and sample approval, the mold is completed and ready for production.
CNC engraving
The die-casting department will set up the mold and die in the die-casting machine, then adjust the furnace temperature and injection pressure, also set up water lines if necessary. After installation, we will try injection and confirm the quality of raw models, then setting automatic injection to start production. After die casting, we need to remove the extra materials around the raw models to get each separate model.
Automatic die casting
On injected products, there are parting line and some burrs which need to be removed by different tools. There are also some tiny pores on the surface of the raw model, after polishing, the surface will be smooth and glossy, even look like a mirror.
Automatic polishing
After zinc alloy hot chamber die casting, deburring polishing, raw model cleaning to make the surface smooth, it comes to the plating process with firstly a copper base and then nickel, and finally plating other colors with oil sealed to prevent oxidization.
Double plating
Filling paint in the closed recess area on semi-finished products after polishing / plating called coloring.
There are three kinds of paint – soft enamel, colorful epoxy and soft cloisonne.
Soft enamel and colorful epoxy are filled on plated products. Soft enamel is less shiny, however colorful epoxy is bright-colored and shiny.
Soft cloisonne should be filled on the raw models then polished when the paint gets solid till seeing different color area, and finally plated. So there will be tiny polishing lines on the soft cloisonne surface, and the metal borders are at the same level as the colored area which is the feature of soft cloisonne. 。
