Received the Taiwan patent certificate for the FS micro spray gun.

The application of water-based moisture-proof materials can significantly reduce the drying time while ensuring a bubble-free film formation.

The special valve mechanism system allows for the application of conformal coating materials without liquid dripping and enables the atomization or line spraying of moisture-proof insulating materials with a diameter of 2mm or less in a short time with a high-speed response. It has shown its effectiveness particularly in the application of VOC-compliant water-based conformal coating materials. The application of water-based conformal coating materials had previously faced challenges such as bubbles and long drying times. However, with the development of a star-shaped nozzle, bubble-free film application has become possible, achieving high atomization performance. Additionally, the significant increase in non-blurring after application has led to a reduction in drying time (2 to 5 minutes at room temperature, though this varies with film thickness). The application gun is a tool-less disassembly and assembly FS-type micro spray gun designed for thin film application, equipped with the new star-shaped nozzle and a high-durability needle necessary for dot spraying, and operates through a dedicated stitch timer system.

Selective conformal coating for VOC. (Patent acquisition)

We developed that the coating valve improved in FS type micro spray gun of our company enabled selective coating to have fine edge definition with a thin film less than 50 microns in high density materials. This is suitable for the field of conformal coating industry of coating solvent less or water-based materials of the VOC type having high solid content with high viscosity. (Patent acquisition)

Two methods of electrostatic micro-spray are prepared: one for forming thin film coatings using low viscosity materials, and the other for film formation using medium to high viscosity coating materials in the range of several tens of micrometers.

The electrostatic micro-spray for forming films with medium to high viscosity coating materials, which can create films several tens of microns thick, utilizes a screw extension and an air cap with a star-shaped design (patented) to finely atomize viscous materials into high microparticles. These particles are then charged in a corona charging area where electrostatic application occurs. Features: - Capable of thin film coating from 350 angstroms. - Reduction in the amount of coating liquid used. - Can coat three-dimensional complex shapes. - Good edge coverage.

It is a circular type FS micro spray gun that can be easily disassembled and assembled without tools, making maintenance tasks such as cleaning and washing easy, and it features a star-shaped nozzle (patent pending).

This spray gun utilizes a unique automatic coating nozzle mechanism and has successfully added a narrow and small circulation circuit in front of its discharge nozzle, allowing for the uniform spray application of liquid materials containing fillers that are prone to settling. The specially developed nozzle features a star-shaped tip (patent pending), which promotes fine atomization, allowing liquid particles to adhere to uneven surfaces without excessive bouncing. Additionally, due to increased viscosity, the liquid particles form a uniform film without dripping.

Developed a micro spray gun with a leaf nozzle capable of forming a wide pattern for thin film coating and granulation.

A micro spray gun with a leaf nozzle has been developed to create a wide pattern by applying micro-vibrations to atomized droplets. This further improves the coating of the bottom and sides of uneven surfaces.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.
