Now people are dazzled by all kinds of PC boards on the market. There are many kinds of PC board processing. What are the specific ones? What does each type of processing mean?

The types of PC board processing mainly include the following:

PC board cutting, PC board carving, PC board drilling, PC board milling, PC board bending, PC board hot bending, PC board hot pressing, PC board stamping, PC board bonding, PC board polishing, PC board printing, PC board blister, blow molding, compression molding, etc. PC board cutting. PC board cutting process is relatively simple, easy to operate.

At present, a large number of plastic plates are being sold in the market, which is a very broad industry. Plastic sheet accounts for almost one third of the materials used for processing products in the current market, second only to metal and wood. Facts have proved that the current plastics industry is very promising. If you want to succeed in this industry, you must first understand the product knowledge. At present, the popular plastic plates in the market are: plexiglass plate, PC, PS and MS plate. These plates are very similar. How to distinguish plexiglass, PC plate processing, PS organic plate and MS plate, and how to compare these plates, especially transparent plate.60b1d543588f3.jpg

1: Plexiglass (acrylic) is respectively: extrusion plate and casting plate. The identification of extrusion plate is good in transparency. With the original identification method, when the fire is burning, the flame is clear, there is no smoke, there are bubbles, and the filament can be pulled out when the fire is extinguished. The identification of casting plate is: higher transparency, smokeless, bubbly and squeaky when burning, and no wire when extinguishing.

2: PC board processing, identification method is: high transparency, good impact resistance, not broken, fire burning is basically not burning, flame retardant, and will emit some black smoke.

3: PS organic board, recognition method is: General transparency, reflection will see pockmarks. It is brittle and easy to crack. There will be a click when it hits the ground. A large amount of black smoke will be produced when burning with fire.

4: MS board, recognition method is: General transparency, reflection will see pockmarks. A large amount of black smoke will be produced when burning with fire. Basically, it is close to PS board, but its flexibility and processing performance are better than PS organic board.

Compared with the same color, it's almost impossible to recognize what those boards are. If consumers don't know the product knowledge, it will bring opportunities for sellers to cheat. Make the seller profitable.

Assuming that these kinds of plates are all transparent and colorless at present, consumers can only identify them as colorless and transparent, but cannot identify which are plexiglass (acrylic), which are PC endurance plates, etc. Because of this, some unscrupulous businessmen will cheat some customers, using PS board, Ms board to act as plexiglass (acrylic), using plexiglass to act as PC endurance board! Invisible business can seek greater benefits. In fact, this will bring serious cycle consequences to customers, because different raw materials have different processing properties.
