The products we process are widely available for medical, industrial, and general household use. Since the packaging method varies for each product according to specifications and applications, all products are packaged by hand. To ensure that we deliver a reliable and clean product, we always strive for careful packaging. We can accommodate various packaging methods tailored to product needs. Please feel free to contact us when you need assistance.

All medical device filter products are individually packaged. Using a vacuum sealer, they are enclosed in gas barrier film and packed into designated boxes according to the specified quantity. Filters with frayed non-woven fabric, wrinkled individual bags, or without air holes are considered defective products, so we conduct thorough visual inspections of both the filters and bags during packaging. To consistently deliver products that meet quality standards, we always strive for careful packaging under strict quality control. We have received very positive feedback from our customers. Regarding packaging methods, we can accommodate a wide variety of requests, so please feel free to consult us about anything.

Since our establishment, we have specialized in the adhesive processing of caps for water purification filters. Here, we would like to introduce the adhesive processing of small-sized filter caps. This product uses caps made of ABS resin on the top and foamed PE on the bottom, with different materials for the upper and lower parts. The application area is very narrow, and the amount of adhesive needs to be delicately adjusted, requiring advanced adhesive technology. Our experienced staff carefully processes the caps using only their sense of touch, allowing us to produce high-quality products that meet quality standards. We take pride in our work done by "hand" and "eye." With our reliable technical skills, we respond to various needs. If you have any manufacturing concerns, please feel free to consult with us.

Our company specializes in the adhesive processing of caps for water purification filters. Among these, commercial filters are particularly large in size, and the caps used are flat caps without grooves, which require high adhesive precision. Therefore, all work processes are carried out manually. Our experienced staff carefully processes each item, allowing us to respond swiftly and faithfully to our customers' diverse needs. We create reliable products daily with our solid technical skills. If you have any manufacturing concerns, please feel free to contact us.

• Processing Contract

Our company specializes in assembly, inspection, and finishing processes that are entirely manual. We can design and manufacture the necessary equipment and jigs for each task from scratch, reflecting our customers' requests and incorporating them into the workflow. 【Examples of Manufacturing Jigs】 ■Preventing the Mixing of Similar Products We received a request to "implement measures to prevent the mixing of other products among several products that have slightly different sizes," and we created a dedicated jig for this purpose. The design ensures that other products cannot fit into it. ■Length Inspection Jig We received a request to "perform length inspections on all products immediately after processing," and we proposed a jig tailored to the customer's needs, producing a jig for length inspection. To match the product specifications, we have incorporated steps at the longest and shortest parts, allowing for a quick visual check to see if the processed product fits within tolerance just by inserting it into this jig. If you have any issues with processes that are considered difficult for machines, please feel free to contact us, and we will be happy to assist you.

Our company specializes in the adhesive processing of activated carbon fiber filters for water purification. The processing steps for the products we undertake mainly include "adhesive processing," "assembly processing," "finishing processing," and "inspection processing." In some cases, we also manufacture using specialized machinery. If necessary, we can accommodate the production of jigs and specialized machinery within the manufacturing process. We can fully reflect our customers' requests, designing and producing from scratch and incorporating them into the workflow. 【Examples of Jig Production】 ■ Crimping Fixing Jig We produced a crimping jig to hold the filter in place during the assembly of the water purifier filter until the adhesive sets. We created three types of jigs tailored to the length of the filter, which improved the quality of the product. In addition to assisting with product commercialization, we also provide the best proposals for quality improvement, so please feel free to contact us if you have any concerns.

At our company, all visual inspections are conducted by eye. Under thorough quality control in a clean booth specialized for pest prevention, skilled employees reliably detect foreign substances and abnormalities. We can accommodate a wide variety of products, from small lots to mass production. If you have any concerns regarding visual inspections, please feel free to contact us. 【Visual Inspection Process for High-Performance Perforated Plates】 ■ Appearance Inspection (foreign substance adhesion, shape defects, scratches, wrinkles, unevenness) ■ Thickness Inspection (using product-specific jigs) ■ Quantity Inspection (counting quantity, classification of good and defective products)

• Processing Contract

Our company specializes in the adhesive processing of caps for water purifier filters. The processing method involves applying Arlon Melt adhesive to cylindrical filter materials and attaching specialized caps tailored to each application. Any "excess adhesive" or "eccentric misalignment of caps" is considered defective, so the amount of adhesive applied must be adjusted in gram units. Due to the complexity of the process, all steps are performed manually. With meticulous craftsmanship unique to handwork, we create high-quality products that pay attention to detail every day. Our customers are very satisfied with our products. If you have any manufacturing concerns, please feel free to consult with us. We are here to help with anything!
