We would like to introduce a case that solved the customer's concern about the difficulty of managing a large number of welded parts. Additionally, the customer was troubled by the difficulty of maintaining dimensional accuracy due to deformation and warping caused by welding, as well as concerns about the strength of the welded sections. By switching from welded products to lost wax, dimensional accuracy improved, and strength increased. The number of welded parts was reduced, leading to lower management costs. [Challenges] ■ Welded parts have a large number of components, making management difficult. ■ Maintaining dimensional accuracy is challenging due to deformation and warping from welding. ■ There are concerns about the strength of the welded sections, and we want to address this. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case where we switched from overseas supply to domestic supply, achieving stable quality and improved delivery speed. The customer in question was sourcing products from overseas, but due to the impact of the coronavirus, their supplier was locked down and they could no longer receive products, prompting them to search for domestic suppliers. Our company is capable of production both domestically and overseas, but considering the customer's circumstances, we proposed domestic production. We were able to provide products that are equivalent to those from overseas manufacturers in a stable manner. [Background] - The supplier was locked down due to the impact of the coronavirus, and products could no longer be received. - The advantages of overseas production have decreased due to rising labor and material costs and demands for price increases. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case where switching from fully machined products to lost wax casting achieved cost reduction and weight reduction. The customer in question was struggling with high processing costs for parts being machined from blocks (difficult-to-cut materials) and wanted to reduce weight due to their heaviness. After reviewing the customer's drawings and intended use, we proposed a shape that could reduce processing man-hours. This resulted in over 50% cost reduction and approximately 15% weight reduction by incorporating material removal. 【Case Overview】 ■Challenges - High processing costs for parts machined from blocks (difficult-to-cut materials) - Desire to reduce weight due to heaviness ■Results - Successfully reduced processing man-hours, achieving over 50% cost reduction - Achieved approximately 15% weight reduction by incorporating material removal *For more details, please refer to the PDF document or feel free to contact us.

Lost wax casting is a method that allows for the production of a wide variety of metal parts by injecting wax into a mold to create a high-precision wax model, assembling it in a tree-like structure, coating it with refractory material, and then pouring metal into the remaining mold after the wax has been removed. Design changes such as adding ribs or modifying dimensions can be easily accommodated by adjusting the mold. It features high design flexibility, the ability to adapt to complex shapes, and a wide range of material options. 【Features】 ■ Inexpensive and highly durable molds ■ Freedom in material selection ■ High design flexibility ■ Reduction in the number of parts is possible *For more details, please refer to the PDF document or feel free to contact us.

"Lost wax" is a casting method that utilizes the property of wax (paraffin) to melt at relatively low temperatures. By injecting wax into a mold to create a high-precision model, and then pouring metal into a mold based on that model, it can flexibly accommodate complex shapes regardless of the material. In addition to excellent casting surface and dimensional accuracy, it can streamline the traditional methods that were divided into multiple processes and parts, achieving labor savings and rationalization, resulting in a cost reduction of over 50% (compared to our company). 【Processing Examples and Benefits】 ◎ Welded Products ■ Traditional: Process multiple parts → Weld ■ Lost Wax: Cast → Process ◎ Processed Assembly Products ■ Traditional: Process multiple parts → Assemble ■ Lost Wax: Cast → Screw processing ◎ Fully Processed Products ■ Traditional: Machining from a block ■ Lost Wax: Only casting (no processing required) *For details, please request materials or view the PDF data from the download.
