What are the key points of sandblasting technology?

Sand blasting machine is the commonly used equipment in the experimental teaching and denture processing in the specialty of oral technology. Its structure is relatively simple and easy to self-control. Therefore, try to use common industrial materials, civil building materials, scraps and common denture processing materials, developed a box type folding sandblasting machine. Domestic equipment in addition to simple structure, relatively stable performance, easy processing, low cost, manufacturing and maintenance convenience, but also has the characteristics of folding. Equipment and Materials

There are several types of formaldehyde resin, self-curing resin rods, plate edge material, stamping die plastic packaging barrels, emery plastic packaging barrels, industrial air gun, pressure pipe, metal pipe diameter, the syringe needle, led flashlight, power adapter, mini lathe (if no lathe, car parts need to be processed), rocker drilling, carpentry trimming machine, the necessary amount of blade tools etc.

Nozzle assembly manufacturing

Dry sand blasting machine sandblast principle generally can be divided into the press in type and suction type two kinds, inhaled sandblasting machine structure is simple, suitable for the production of inhaled sandblasting machine sandblast principle is the use of compressed air from airway high-speed nozzle, create a partial vacuum, will the sand grinding with high pressure air jet from the nozzle assembly, according to the principle of inhaled sandblasting machine, according to the sources of materials, Design and manufacture nozzle assembly of different shapes.

The outer diameter of the metal pipe is made with the formaldehyde resin rod self-condensing resin number injection needle (used for the airway nozzle), and the outer diameter of the pressure pipe is made through the resin bonding process of the lathe to complete the production of the nozzle components of the replaceable nozzle.

In order to reduce the teaching cost, the component nozzles can be made of two kinds of materials, namely, gel resin and waste alloy, which can be used as wearable parts.
