We would like to introduce a comparison of machining costs and core product costs, along with an example of cost reduction. Customers considering the production of moderately sized cast components require a flat surface on the component side for installation onto the structural surface. Due to the high costs associated with machining at this size, they sought advice on finding a better method to reduce unit costs. In response, we established a core for creating flat surfaces tailored to the size of the cast components and conducted a comparative analysis of machining costs. We designed a cylindrical projection for φ holes in the core. As a result, a core that could reduce costs compared to machining and hole processing was adopted. [Challenges] ■ Considering the production of moderately sized cast components, but a flat surface is needed on the component side for installation onto the structural surface. ■ Due to high costs associated with machining at this size, they are looking for a better method to reduce unit costs. ■ The installation method involves bolt fastening, so they would also like to reduce the costs of φ hole processing if possible. *For more details, please refer to the PDF document or feel free to contact us.

We received an inquiry from a customer considering the electric lock specifications for aluminum gates, stating, "Having an external unit on the cast body negatively affects the design. Is it possible to store the unit inside the cast material?" In response, we proposed a solution where the vertical frame of the aluminum cast gate is made with a hollow structure using a core for casting, allowing the electric lock unit to be stored in the hollow section without affecting the exterior design. As a result, our proposal was accepted, and the electric lock unit is now stored in the hollow section of the cast material. [Issues] ■ Considering electric lock specifications for aluminum gates ■ An external unit on the cast body negatively affects the design ■ Desire to store the unit inside the cast material *For more details, please refer to the PDF document or feel free to contact us.

I will introduce two examples and benefits of utilizing 3D printers. In the case of "transitioning from metal machining to 3D printing," it is possible to reduce prototype costs and respond to deadlines with a sense of speed. Even for parts that require fit verification, the fit confirmation can be carried out smoothly. Additionally, in the case of "products that require fitting," it becomes possible to confirm fits and casting parting lines at an early stage, which leads to the elimination of the risk of rework and a reduction in construction time. [Features] < [Method Transition] From Metal Machining to 3D Printing > ■ Reduction in prototype costs ■ Shortened delivery time < [Functionality Verification] Products Requiring Fitting > ■ Elimination of the risk of rework ■ Confirmation of casting parting lines *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce a case where the material was changed from wood to aluminum. By converting the manufacturing method from wood to aluminum casting, the product's appearance can be maintained without deterioration over a long period. In this case, aluminum casting was adopted because the product was exposed to wind and rain. Additionally, it is possible to effectively express the texture of wood through painting. 【Features】 ■ By changing to aluminum cast products, weather resistance and durability are improved. ■ Reduction of regular maintenance costs is possible. *For more details, please refer to the PDF document or feel free to contact us.

MIYAKI's landscape products are active in a wide range of fields, including public facilities such as bridges, parks, and stations, educational institutions like universities, and religious facilities such as temples and shrines. Their ability to respond to design requirements and MIYAKI's commitment have led to high evaluations. The sand molds used in the foundry are primarily made from natural sand or synthetic sand, with a focus on using fine-grained synthetic sand. This allows for the realization of a finely detailed casting surface. Additionally, even for drawings where the contours and cross-sections are unclear, we support the creation of casting designs through meticulous discussions with our customers. Products with high design quality, which are difficult to achieve through cutting processes, can be manufactured. 【Features】 - Uses fine-grained synthetic sand and high fluidity alloys (3A) - Supports drawings with unclear contours and cross-sections through detailed discussions - Capable of adding various patterns to the casting surface, focusing on appearance - Shapes that are difficult to achieve through cutting can be cast *For more details, please refer to the PDF materials or feel free to contact us.

Sand casting allows for the creation of sand molds from models, enabling the expression of complex designs and textures. It also provides a unique texture and feel characteristic of sand molds. In cases of low production volume, the molds are made from wooden models (patterns). Even for mass production, molds can be produced at a low cost by replacing wooden patterns with cast products.

To produce secondary (recycled) metal, only about 3% of the energy required to create new metal is needed, making it very economical due to the possibility of semi-permanent recycling. Aluminum does not rust, and it prevents corrosion by forming an oxide film on its surface when exposed to air. Further corrosion resistance is achieved by anodizing the surface.
