Patterning process of injection mold

Patterning is a relatively common process in injection molds. Patterning is actually a common process in the surface treatment of injection molds, which will directly affect the appearance and surface strength of the product surface. Mold patterning is also called mold biting, mold etching and mold etching. Because of its low process cost, rich effects and high speed, it is widely used.

As a common process for mold surface treatment, what is the purpose of patterning? Yes, it is to improve the appearance and texture of plastic parts, and it is the product showing multiple changes or new designs.

Let's take a look at the complete sequence of the whole set of procedures.

1. The first is to clean the surface of the mold cavity to remove the grease on the surface.

2. Paste the cavity that is not to be printed with adhesive tape or paint with anti-corrosion paint to avoid corrosion. This is the most time-consuming of all the processes. This process is commonly called "sealing".

3. Anticorrosive paint drying in the "sealing" process.

4. Use absorbent cotton to carefully wipe the surface of the cavity to be bitten to ensure that there are no impurities and dirt to ensure the effect of biting.

5. After the preparatory work is completed, we spray paint the surface of the cavity that will be sunburned and soak it in the corrosive solution. During the corrosion process, observe the sunburn and repeatedly soak to achieve the predetermined bite.

6. "Sandblasting" has two purposes. The first is to remove residual liquid on the surface of the cavity, and the second is to adjust the gloss of the pattern, using different sand and pressure to spray different gloss and brightness.

7. Finishing work, quickly clean the cavity surface, apply anti-rust liquid and send the mold parts back to the injection mold manufacturer.
