We would like to introduce a case study of "Reducing personnel and achieving high-quality multi-material molding through two-color molding" that our company conducted. In the resin insert molding process, it was a semi-automatic molding, requiring one operator to be dedicated to the molding machine, resulting in unstable product quality. By switching from semi-automatic molding with a single-color machine to two-color molding, we were able to achieve automatic molding, reducing the workload by approximately one operator. Quality also stabilized, achieving a 4% reduction in process defect rate. 【Case Overview】 ■ Challenge: Operators were dedicated to semi-automatic molding, leading to unstable product quality. ■ Solution: Transitioned from semi-automatic insert molding with a single-color machine to two-color molding. ■ Effects: - Enabled automatic molding, reducing the workload by approximately one operator. - Quality stabilized, achieving a 4% reduction in process defect rate. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case of "laser coating removal on 3D shapes" that our company conducted. There was a challenge in wanting to remove the coating from the top and sides of a circular product with multiple 3D protrusions, which required five processes per location. Additionally, the cost of the fixtures needed for the protrusions was significantly high. We created a rotating fixture and adjusted it so that the surface to be laser processed would be horizontal when rotated. This allowed for a significant reduction in initial and processing costs, resulting in cost savings. [Case Overview] ■ Challenges/Background: Five processes required per location, leading to high fixture costs. ■ Solution: - Created a rotating fixture to ensure the processing surface was horizontal. - Enabled continuous processing by linking the laser machine with the fixture. ■ Results/Effects: Achieved significant reductions in initial and processing costs, leading to cost savings. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a development case of the "Painting Masking Jig" that our company has worked on. The product has a masking area at the intermediate position inside its cylindrical shape, while all other areas are within the painting range, making it difficult to secure the jig. Additionally, a size equal to or larger than the product's inner diameter was required, which posed a challenge for insertion. We successfully enabled attachment and detachment by utilizing deflection and managed to close the gap between the product and the jig. As a result, we were able to mask the targeted masking area, and the attachment and detachment process was carried out smoothly. 【Case Overview】 ■ Challenges/Background: There is a masking area at the intermediate position inside the cylindrical product, making it difficult to secure the jig. ■ Solution: Enabled attachment and detachment using deflection and closed the gap between the product and the jig. ■ Results/Effects: Successfully masked the targeted masking area and carried out the attachment and detachment process smoothly. *For more details, please download the PDF or feel free to contact us.

We would like to introduce our "Plastic Coating." "Spindle Coating" involves rotating the object to be coated while it passes in front of a fixed spray gun, while "Robot Coating" utilizes a multi-axis robotic arm that can replicate the movements of human hands during the coating process. Additionally, "Laser Trimming" is a technology that removes the surface coating of resin to reveal the underlying substrate or coating. Please feel free to contact us for inquiries. 【Lineup (Excerpt)】 ■ Spindle Coating ■ Robot Coating ■ Vacuum Deposition ・ Continuous Deposition, Discontinuous Deposition ■ Plastic / Laser Trimming * For more details, please refer to the PDF document or feel free to contact us.

Kobatec Co., Ltd. features four types of "printing": "silk screen printing, pad printing, hot stamping, and laser." "Silk screen printing" can print on various shapes such as flat surfaces, curved surfaces, and cylindrical surfaces. "Pad printing" excels at printing small characters and fine lines, while "hot stamping" allows for labor-saving processes. "Laser" can process complex objects. [Features] - Silk Screen Printing: Capable of applying thick ink, excellent weather resistance, and can print on various shapes such as flat surfaces, curved surfaces, and cylindrical surfaces. - Pad Printing: Excels at printing small characters and fine lines. - Hot Stamping: Can finish with a metallic appearance, enhancing design quality and allowing for labor savings due to the elimination of drying processes. - Laser: When integrated softly, laser irradiation is possible, enabling reduced processing time and the ability to process complex objects such as cylinders and steps. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the feature of Kobatec Co., Ltd., known as "two-color molding." This is an injection molding method that adds a different resin layer to the base molded part within the mold, enabling a combination of properties that cannot be achieved with a single material. By adopting two-color molding, it becomes possible to bond different materials together, significantly reducing the assembly process and improving cost-effectiveness. 【Features】 ■ Adds a different resin layer to the base molded part within the mold ■ Enables a combination of properties that cannot be achieved with a single material ■ Allows bonding of different materials ■ Significantly reduces the assembly process, improving cost-effectiveness *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the characteristic of Kobatech Co., Ltd., which is "integrated production." As a benefit to our customers, multiple manufacturing processes can be completed with just one order slip, and a single manager can handle multiple production plans. This eliminates inter-process transportation, allowing for shorter delivery times. Furthermore, the absence of inter-process transportation leads to cost reductions. Through centralized management, we guarantee excellent quality from molding to secondary processing. We also accept individual processes such as molding only or painting only. 【Customer Benefits】 <Reduction of Management Workload> ■ Multiple manufacturing processes can be completed with just one order slip. ■ A single manager can handle multiple production plans. ■ Shorter delivery times are possible due to the elimination of inter-process transportation. <Transportation Cost Reduction> ■ Cost reductions can be achieved as there is no transportation between processes. *For more details, please refer to the PDF document or feel free to contact us.
