In "die casting," product shapes with undercuts may be rejected for casting because they cannot be removed from the mold during demolding. Additionally, in "ceramic shell casting," product shapes with gaps of less than 1 cm cannot be cast because sufficient layering cannot be achieved, resulting in brittle mold strength. Therefore, with the "block mold method," the gypsum molds can be easily broken apart by striking them, allowing for the casting of product shapes with undercuts. By pouring a slurry (liquid) made of water and gypsum into the mold, it is possible to cast even intricate product shapes with fine gaps. *For more details, please refer to the PDF materials or feel free to contact us.*

Company O, a manufacturer specializing in apparel, has been receiving orders for mass-produced accessories until now. In recent years, there has been an increase in requests for custom products, but producing them on the same line as mass-produced items was not profitable, leading to the unfortunate situation of having to decline such orders. While we wanted to accept these requests, finding a profitable method was a challenge. Therefore, we proposed establishing a separate casting line specifically for custom products. Since these are one-of-a-kind items, we can set up the line with smaller equipment than what is used for mass production. Additionally, the molds for casting are smaller, which helps reduce running costs for consumable materials, leading to secured profits. [Case Summary (Partial)] ■ Background - Custom products are not profitable ■ Equipment Introduced - Small electric furnace - Casting machine YGP-2SN *For more details, please refer to the PDF document or feel free to contact us.

The Product Development Department is engaged in the daily production of prototypes. Prototypes were entirely outsourced, involving a long process from the creation of simple molds to shaping and cutting with metal, which took at least 1 to 2 months for completion. Additionally, creating molds for a single part cost several hundred thousand yen, leading to expenses every time a revision or mass production prototype was requested. Therefore, instead of using a metal printer, we utilized a 3D printer and our company's casting machine to internalize the production of prototypes. By completing prototypes in-house, we were able to reduce both lead times and costs, allowing us to work on prototypes until we were satisfied with the results. [Background] - Prototypes were outsourced, taking at least 1 to 2 months for completion. - Costs were incurred every time revisions or mass production prototypes were requested. - We considered purchasing a metal printer to internalize prototype production, but abandoned the idea due to the need for an initial investment of over 40 million yen. *For more details, please refer to the PDF document or feel free to contact us.*

At Company P, a manufacturer of production machinery, over 100 parts are required to create a single product. Each part's prototype is outsourced, and it takes a long process involving the creation of simple molds, shaping with metal, and then fine-tuning through machining, resulting in a lead time of 1 to 1.5 months for the completion of prototypes. Therefore, we decided to utilize the 3D printer already owned by the company along with our casting machine to produce prototypes in-house. The block mold method reduces the time required by about 90% compared to traditional casting methods that use molds, and since there is no need for mold costs, it achieves low costs. [Background] - Prototypes for each part were outsourced. - The lead time for completing prototypes was 1 to 1.5 months. - Significant costs were incurred for creating molds for each part, leading to challenges with costs and lead times every time improvements were made. *For more details, please refer to the PDF document or feel free to contact us.

In solid casting, different equipment and consumables are used compared to those used in the ceramic shell method, resulting in changes to the workflow. For wax injection into rubber molds, various types of machines are used, ranging from simple atmospheric wax injectors to advanced vacuum/auto-feeder models, depending on productivity and requirements. As you may know, casting refers to the process of pouring molten metal into a cavity of a mold to create a metal piece that has the same shape as the cavity. However, depending on the shape, gravity casting alone may lack reproducibility in fine details. Therefore, several types of physical forces are utilized to enhance the force used to pour the molten metal. **Casting-related equipment required for each process:** - Rubber mold production: Heat curing device / Hot press - Wax mold production: Wax injection machine / Auto wax spot - Wax tree production: Electric soldering iron / Wax worker - Mold production: Vacuum degassing device / Vacuum embedding machine - Mold firing: Firing furnace / 6Kw electric furnace - Casting: Casting machine / 7Kw output mold rotating pressure casting machine *For more details, please refer to the PDF document or feel free to contact us.*

Since the 1950s, the production of jewelry in Japan has shifted from traditional handmade methods to mass production through casting. In recent years, market demands have changed significantly, with an emphasis on aspects like being priceless and having a story, leading to a preference for "personalized jewelry," which has diminished the need for mass production of the same design. In an environment of small lot production, creating prototypes by hand as before incurs high "prototype costs," which must be added to the unit price, resulting in increased costs. Even companies that already have casting lines can enhance production flexibility by separating the traditional wax mold firing process from the 3D printer resin firing process, leading to shorter delivery times and improved product yield. *For more details, please refer to the PDF document or feel free to contact us.*

A hotspot refers to a location where the heat of molten metal concentrates due to the shape of the cavity in the mold. If no measures are taken, the molten metal may come into direct contact and roughen the casting surface, and as a result of concentrated heat, directional solidification may not be achieved, leading to the formation of shrinkage cavities within the casting. Since hotspots are closely related to the turbulence of molten metal, the measures to prevent them are similar to those for the flow path design. However, this column will provide an explanation focused on hotspots. Please take a moment to read it.

Casting, originally referred to as "self-weight pressure (gravity) casting," is fundamentally based on utilizing the Earth's gravitational pull and the weight of metals. This method is employed in sand casting and some ceramic shell casting. However, in the case of metals with low specific gravity (light metals), thin-walled castings, or complex shapes, the molten metal may not fill the tip of the casting solely due to gravity, leading to casting defects known as "nameru." To solve this problem, several forces other than self-weight assist in the casting process. The types of forces used for this assistance categorize the casting methods into what is called "casting schemes." 【Types of Casting Schemes】 ■ Vacuum casting machine ■ Centrifugal casting ■ Pressure casting *For more details, please refer to the related links or feel free to contact us.
