Cylinder is a cylinder-shaped metal part that guides the Piston to move in a straight line. There are two types of cylinder: moving in a straight line and swinging in a reciprocating way. 

   The advantages and disadvantages of the cylinder are obvious, the advantages are simple structure, easy installation and maintenance, the disadvantages are that the cylinder is cast from the factory, after the cylinder has been aging treatment, so that the cylinder casting process generated in the internal stress removal, if the aging time is short, then the cylinder will be deformed in the future operation. Because of these shortcomings, the cylinder can not meet the needs of some manufacturers, based on this, in recent years, the cylinder is gradually replaced by voice coil motor. The types of voice coil motors are mostly divided into cylindrical voice coil motor, rectangular voice coil motor, flat voice coil motor and swing voice coil motor, among them, cylindrical voice coil motor, rectangular voice coil motor, flat voice coil motor is to do reciprocating linear motion, swing voice coil motor is to do swing reciprocating motion. 

    And Voice Coil Motor circumvents the shortcomings of the traditional cylinder, but has the advantages of the traditional cylinder, and even more advantages. Voice Coil Motor structure is simple, smooth operation, fast speed, fast response, long life, low noise, suitable for a variety of harsh environment. 

     Kunshan Deep Plough Voice Coil Motor R & D, production and sales for more than 10 years, Tongmao voice coil motor are adopted European and n technical standards and processing technology, can achieve the same product import substitution.
