Seal the traditional percussion method, often resulting in crooked fonts, shades, and low efficiency. For a long time, how to improve quality has always been plagued by signs of engineering and technical personnel of industrial enterprises. Pneumatic marking machine (aka computer stylus cutting plotter) although to engraving, but its high price allows the many signs discourage a small number of SMEs. I plant development and design of the sign parameters completely solved Unit hit the defects, and low prices, a product launched on the market has been widely recognized. 
 Applications: 
 Mechanical, electrical, pumps, valves, automobile and motorcycle, electrical appliances, on all types of aluminum, copper, stainless steel, plastic plate, metal plate can be printed on the changes in the parameters: such as the specific type, date, batch number, serial number, serial number . 
 How it works: 
 1. The high-frequency quenching, such as processing turn dial steel under loads (hand or rubber hammer to drop), engraved in the metal out of a certain depth (0.1-0.3mm) deep in the letters or numbers; 
 2. After heat treatment of steel can turn the dial to the desired letter or number, easily replace the word; 
 3. Marking the location, spacing Promise regulation by specialized machinery sector; 
 4. To rely on manual adjustment of word spacing; different character height can be achieved by replacing the dial; 
 5. Shape than 200X130MM gripping of various shapes can be engraved signs.
