introduction：*The gate must be designed in the area with the greatest wall thickness。 *Gate should not be located near high stress area。 *For long parts，In particular, enhanced blends，As motor may，The gate should be placed lengthwise rather than sideways or in the center。 *If in two or more cavities，Parts and gates should be arranged symmetrically along the sprue。 *Axially symmetrical parts，Such as gears、disc、blading，It is preferable to use a partition gate and the gate should be centrally located，Or a plurality of gates are arranged on the three-plate mold，To obtain good actual flow characteristics。 *There are integrated hinged parts in the placement of the gate

introduction： Hefei electromagnetic clutch to introduce you what is the tension controller。 The tension controller is a system developed by a single chip microcomputer or some embedded devices and peripheral circuits，Its a control instrument，It can directly set the tension value required for control，Then directly input the signal of the tension sensor as the tension feedback value，After the deviation is obtained by comparison，Input intoPIDWait for the controller to process，It is best to output to the peripheral actuator to control，Finally, the deviation is minimized，System response fastest purpose。 The tension controller basically breaks up the dynamic tension controller，pulse

introduction：In real life，Most people think that stainless steel is not magnetic，And use magnets to identify stainless steel，This method is very unscientific。 First zinc alloy、Copper alloys can generally imitate the appearance of stainless steel color，Theres no magnetism.，Easily mistaken for stainless steel；And even the ones we use most often304Grade of steel，After cold working，There are also varying degrees of magnetism。Therefore, you can not judge the authenticity of stainless steel only by a magnet。 So how does the magnetism of stainless steel come about？Based on materials physics，The magnetic properties of metals come from the structure of their electron spins，Electron spin genus
