Specification

 Product Description

Static Generator is a high-precision static electricity generator designed specifically for IML (In Mold Labeling) process, aiming to solve industry pain points such as inaccurate label positioning and poor adhesion. By precisely controlling the strength and distribution of the electrostatic field, this device can stably adsorb IML labels onto the surface of the mold, ensuring zero displacement and wrinkles of the labels during the injection molding process, significantly improving product yield and production efficiency. It is suitable for high demand fields such as food packaging, home appliance panels, and automotive interiors. For the core requirement of IML Label Static Electricity. In traditional IML technology, labels are prone to displacement due to airflow or mold vibration, resulting in pattern misalignment or edge warping. Through the uniform static electric field generated by the electrostatic device, the label can be instantly adsorbed to the predetermined position of the mold. Even when facing complex surfaces or micro patterns, millimeter level precision bonding can be achieved, completely eliminating the problems of bubbles and edge glue overflow. Specially designed for IML Label Injection process optimization, this equipment integrates an intelligent control system that can seamlessly collaborate with injection molding machines. Its built-in sensor can monitor the mold status in real time, automatically trigger static electricity generation at the moment of mold opening, and synchronously complete label positioning; During the injection molding stage, the static electric field is automatically turned off to avoid static electricity interference with resin flow.

1. High precision positioning The fitting error between the label and the mold is less than 0.1mm, reducing the rate of defective products.

2. Improve efficiency Reduce single labeling time by 30%, suitable for high-speed production lines.

3. Adapt to complex shapes Can handle surfaces and irregular labels without the need for additional mechanical structures.

4. Reduce material costs Reduce the use of glue or double-sided tape, which is environmentally friendly and cost-effective.

 

Why should we use Static generator for IML ?

1. Ensure accurate positioning of labels

In the film pasting process, the label needs to be accurately attached to the designated position on the inner wall of the mold before the mold is closed. Static electricity generates an electrostatic field, which fixes the label with electrostatic adsorption force when entering the mold, avoiding label displacement or detachment caused by mechanical arm movement or airflow disturbance during mold closure.

2. Improve production efficiency
Static appliances can achieve rapid and continuous adsorption of labels, reducing the adjustment time before mold closure, thereby improving the overall efficiency of injection molding production lines.

3. Adapt to high-speed automated production
The combination of automated robotic arms and electrostatic devices can achieve automatic picking, positioning, and attachment of labels, further enhancing the automation level of the production line.

4. Reduce label deformation and damage
The electrostatic adsorption force is evenly distributed and does not exert excessive pressure on the local area of the label, making it particularly suitable for attaching thin and fragile labels.
5. Reduce energy consumption and costs
Static appliances only work instantly when the label is attached, with low energy consumption and no need to continuously consume vacuum or compressed air.
The structure of the electrostatic adsorption system is simple, the maintenance cost is low, and long-term use can significantly reduce production costs.

 

Application

 1.Robot assisted labeling

After the automated robotic arm picks up the label, the electrostatic device charges the label for a short period of time, and the label is adsorbed on the inner wall of the mold cavity. After the robotic arm withdraws, the label remains stable.

2. Label charging and attachment

By using an electrostatic generator to charge the label, the charged label can be directly attached to the inner wall of the mold with the help of wind or a robotic arm, achieving efficient attachment.

3. Integration with PLC control system

The electrostatic device is linked with the PLC control system. The robotic arm places the label into the mold cavity and starts the electrostatic device. After the label is adsorbed, the vacuum is released to ensure that the label is tightly attached to the mold.

 

Typical application products

What is the working principle ?

The system is composed of an electrostatic generator and an electrostatic generating electrode. The electrostatic generator provides a high voltage for the electrostatic needle of the electrostatic generating electrode to generate the required charge.

The electrostatic generating electrode uses the high voltage generated by the electrostatic generator. The electric charge moves to the surface of the product under the action of the electric field. 

How to operate？

1. Equipment inspection and preparation
Check whether the appearance of the equipment is intact, confirm that the grounding wire is firmly connected, and avoid the risk of leakage or short circuit.

2. Parameter settings
Voltage regulation: Set the output voltage (such as 0-30kV continuously adjustable) through the device panel or remote control, and adjust it according to the label material and thickness.

3. Label charging and attachment

Manual operation: Place the label near the electrode of the electrostatic generator and hold for 1-3 seconds. After the label is adsorbed, move it to the inner wall of the mold.Automated operation: After placing the label into the mold cavity through a robotic arm, the electrostatic device is activated, and the vacuum is released after the label adsorption is completed.

4. Equipment maintenance and safety
Regularly clean the discharge electrode, remove dust and oil stains, and maintain 

Key issues to be addressed

1. Label displacement: Traditional mechanical positioning methods are easily affected by injection molding pressure, resulting in label displacement.
