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 for this size, they sought advice on finding a better method to reduce unit costs. In response, we established a core designed to create a flat surface that matches the size of the cast component and conducted a comparison of machining costs. We also set a cylindrical projection for φ holes on the core. As a result, a core was adopted that allowed for cost savings compared to machining and hole processing. [Challenges] ■ Considering the production of moderately sized cast components, a flat surface is required on the component side for installation onto the structural surface. ■ Due to high costs associated with machining for this size, they are looking for a better method to reduce unit costs. ■ Since the installation method involves bolt fastening, they would also like to reduce the cost 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 impacts 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 designed with a hollow structure using a core for casting, allowing the electric lock unit to be stored within the hollow section, thus not affecting the exterior design. As a result, our proposal was accepted, and the electric lock unit is now specified to be stored within the hollow section of the cast material. [Issues] ■ Considering electric lock specifications for aluminum gates ■ An external unit on the cast body negatively impacts 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 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 the parting lines of cast molds at an early stage, which leads to the elimination of the risk of rework and shortening of construction periods. [Features] < [Method Transition] From Metal Machining to 3D Printing > ■ Reduction of prototype costs ■ Shortening of delivery times < [Functionality Confirmation] Products Requiring Fitting > ■ Elimination of the risk of rework ■ Confirmation of cast mold parting lines (trimming) *For more details, please refer to the PDF document 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 instance, 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.

Our company provides comprehensive support from product design to machining, painting, and shipping after casting, ensuring that customers do not have to deal with multiple points of contact and receive the finished product from a single source. Additionally, we manufacture high-design aluminum castings such as bridges and fences, using the highly fluid AC3A (aluminum alloy casting) material for aluminum castings. We accommodate a wide range of quantities, from small lots to mass production using automatic molding machines, and we can also propose methods for converting to aluminum castings or ways to utilize them upon consultation. [Features] ■ Capability to handle products with high design and aesthetics ■ Integrated production system from "design to casting to painting to shipping" ■ Aluminum casting that has been produced continuously since our founding ■ VEVA proposal capability to solve customer problems *For more details, please refer to the PDF materials 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 are recognized and appreciated. The sand molds used in the foundry are primarily made from natural sand or synthetic sand, with a preference for fine-grained synthetic sand. This enables 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 complexity, which are difficult to achieve through cutting processes, can be manufactured. 【Features】 - Uses fine-grained synthetic sand and highly fluid alloys (3A) - Supports unclear drawings with detailed discussions - Allows for a variety of patterns on 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 document 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 the unique texture and feel characteristic of sand molds. In cases of low production numbers, 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 prevents corrosion by forming an oxide film on its surface when exposed to air. Further corrosion resistance is achieved by anodizing the surface.
