宮田工業所 List of Products and Services

Existing PVC fittings had the challenge of being too large in overall dimensions, making it impossible to maneuver piping in narrow spaces, which led to interference with other components. By compacting the PVC fittings from 100mm to 55mm, we were able to commercialize the product. Using the compacted drainage socket 50 allows for maneuvering piping in tight spaces, resolving the issue of interference with other components. [Case Overview] ■Challenges - Existing PVC fittings are too large in overall dimensions to maneuver piping in narrow spaces. - Interference with other components. ■Solutions - Compacted PVC fittings from 100mm to 55mm for commercialization. - Executed design drafting, prototyping, mold manufacturing, and component molding. *For more details, please refer to the PDF document or feel free to contact us.

There was a challenge in shortening the construction schedule due to the time-consuming process of material arrangement, cutting of PVC pipes, and gluing of PVC fittings using limited equipment on-site. We confirmed the specifications such as the shape and dimensions of the PVC piping used on-site, as well as the bonding points between the PVC pipes and fittings, created drawings, conducted prototypes, and mass-produced pre-processed PVC piping for delivery to the site. After implementation, the on-site work time was reduced from about 3 days to 1 week, allowing for a shortened construction schedule. 【Case Summary】 ■Challenge - Difficulty in shortening the construction schedule ■Solution - Confirmed specifications, created drawings, conducted prototypes, and mass-produced pre-processed PVC piping for delivery to the site. *For more details, please refer to the PDF document or feel free to contact us.

For PVC piping and agricultural materials for plant factories, contact Miyata Industrial Co., Ltd. https://plant-enbi.jp/ 【PVC Piping for Hydroponics】 We process PVC piping for hydroponic systems. (*The photos are examples of processing; we do not sell or install equipment.) Water pumped up flows from the upper pipe to the lower one due to the gradient, efficiently supplying the necessary air and nutrient solution to the plants. Since the power source is only the pump, it is energy-efficient. The structure prevents light from entering (light-blocking type), which helps prevent the growth of moss and algae, significantly reducing daily maintenance tasks such as cleaning, hygiene management, and mold prevention. The pipe structure allows for easy cleaning and length adjustment.
