Our company has a line that allows for smooth painting of thin, light, and unstable workpieces. By drawing in air from below while painting, we can prevent paint splatter from adhering to the underside of the workpiece, solving issues such as the inability to apply double-sided tape and poor tactile quality. Additionally, it reduces the hassle of securing the workpiece and the need for masking! 【Features】 - Smooth painting of thin, light, and unstable workpieces - No paint mist on the underside of the workpiece - No need for workpiece fixation or masking *For more details, please refer to the materials. Feel free to contact us as well.

Our company conducts "precision baked coating" for various products, including cases for electronic devices, medical equipment, laptops, and exterior parts for camera interchangeable lenses. *Our technology has been adopted for the new VAIO product, "VAIO Z"!* We are equipped with advanced facilities such as a super spindle robot painting line, a large automatic painting line, a wall-mounted painting robot line, and a rotary automatic bulb painting machine, allowing us to respond to various needs. All processes are carried out in a clean environment, and we can also accommodate painting of large items up to 2 meters in length. We achieve high-quality and stable painting through robotic painting. **Features** - Possession of a clean room (Class 10,000/100,000) - Two super spindle painting robots can paint leather-tone patterns simultaneously - Capable of uniform finishing for magnesium alloy coatings *For more details, please refer to the materials. Feel free to contact us with any inquiries.*

In our company, we introduced a super spindle painting line in 2007. We mainly paint exterior parts for interchangeable lenses for digital single-lens reflex cameras. The painting is done with two super spindle painting robots, capable of processing patterned coatings such as leather tones simultaneously. (The painting area is a clean room with a class 100,000 standard) 【Painting Process】 ■ The workpieces to be painted are set on a dedicated cart within a clean bench and transported into the clean room (items like outer boxes and packs that could cause contamination are shut out). ■ Fine dust remaining on the surface is removed using brushes and ionizing guns. ■ The workpieces pass through an automatic dust removal and ionizing device and are automatically transported to the painting room in a dust-free state. ■ Painting is done with two super spindle painting robots. ■ In the main drying oven, they are baked and dried at specified temperatures and times, followed by an appearance check by dedicated inspectors. ■ Silk screen printing and pad printing & drying. ■ After passing the printing inspection, the process is complete. * For more details, please refer to the PDF materials or feel free to contact us.

We have newly established a spindle painting line with an infrared drying oven for small parts painting. Since the first and second painting booths are independently separated, it is possible to perform 2-coat, 1-bake painting once set. Each painting section is equipped with six spray guns, allowing for a uniform and stable paint film even on complex-shaped products. As it is a closed-type line, it can shut out dust from the air, ensuring thorough measures against painting defects such as spots and thread debris. 【Features】 - 2-coat, 1-bake painting possible once set - Equipped with six spray guns - Uniform and stable paint film achievable even on complex-shaped products - Shuts out dust from the air - Thorough measures against painting defects such as spots and thread debris *For more details, please refer to the PDF document or feel free to contact us.

We have introduced a new robot line as an updated facility for our flat automatic painting machine (reciprocating type fixed gun). As a result, the setup time during product changeovers has been reduced by 90% compared to the conventional reciprocating automatic painting machine, significantly improving productivity. *Note: The time for changing paint is not included. [Painting Process] ■ Through the air shower room to the painting room ■ Painting input ■ Painting robot with 4 guns ■ Painting booth / Far-infrared conveyor type drying oven *For more details, please refer to the PDF document or feel free to contact us.

At Shuangsan Optical Coating Co., Ltd., we perform painting on magnesium alloys. Our first large-scale painting line has been completed. We would like to introduce our smart reciprocating + robotic automatic painting line (trolley conveyor line). The maximum painting size is 2m x 1m. We do not compromise on quality just because the items are large. We can achieve high-quality painting without dust attachment, utilizing the painting technology for optical products that we have cultivated over many years. After delivery, all processes from primer application to topcoat and drying are performed automatically. 【Equipment】 ■ Zinc phosphate coating treatment equipment ■ Large painting robot ■ Smart reciprocating automatic painting machine ■ Drying line *For more details, please refer to the PDF document or feel free to contact us.

We perform painting on magnesium alloys. The molding methods include die casting, thixomolding, and lost wax, and even for items with non-smooth surfaces, we apply putty corrections for defects such as air holes, flow marks, and shrinkage, smoothing the surface before painting, which allows for a uniform finish. Additionally, to prevent the occurrence of defective products due to the adhesion of dust and debris floating in the air, as well as lint from clothing, we conduct painting in a Class 10,000 clean room. 【Features of Magnesium Alloys】 ■ Lightweight (two-thirds the weight of aluminum) ■ Stronger than plastic ■ Conductive and shielding properties ■ Recyclable *For more details, please download the PDF or feel free to contact us.
