Static is stationery electric charge, which forms on the surface of non-conduction ( Insulators ) and un-grounded isolated conductors. Friction pressure and separation are the main reason for creation of static. If two materials come in contact with each other and then separated, electronics may be transferred from one to other. A charge in temperature also create charge. Static electricity is thus the imbalance of positive and negative charges. When a moving web comes in contact with a rubber, steel or aluminium roller and separated from it, static electricity gets created on web both web and the roller. Bare films, paper and rubber roller being non-conductive, there is no free flow of electrons. Thus the static charge on films and paper dissipate very slowly. Metals roller are foils being conductive allow free flow of electrons to ground, since they are invariability earthed conductors will develop a static charge if they are insulated from ground. The magnitude of the static charge will depend on the materials, applied forces, separation rate, temperature and relative humidity.

Detailed introduction: Introduction of the traditional conditions of injection molding machines: In the injection molding machine is carries on after all kinds of plastic the heating, melts the melt, the agitation, turbo-charged, the plastic fluid pours into the mold to file an accusation, completes a work piece injection molding the equipment.Consuming energy: Matched molds. Mode locking. Shoots the rubber. Sol. Guarantees the pressure. Cooling. The die sinking and so on several stages need the different pressure and the current capacity, but the oil pump electrical machinery in the constant speed revolution, creates the energy waste. The craft is unreasonable: The different working procedure oil pump's rotational speed is the same, has not been able to real-time change electrical machinery rotational speed because of the technological requirement. The work piece service life is short: The injection molding machine oil temperature is high. The noise is big. The service life of the machinery and the seal lessens under the most tremendous pressure and the current capacity.The electrical machinery protection is insufficient: The electric motor frequent line start, the electric current is big, the life lessens, simultaneously bring big pollution to electrical network.

Inductive Proximity Sensors are the most widely used Sensor Technologies in the modern process control environment . The coil at the sensing face of the sensor is excited by a Sine-wave oscillator which produces an Electromagnetic field in the sensing face. When a metal object moves into the sensing range, due to Eddy Current effect, the oscillations are being dampened in the sensing circuitry. This change in status is detected by the detector circuit and is further processed by output logic driver section
