カルモ鋳工 Company Overview

Thank you for visiting the 29th Mechanical Components Technology Exhibition [Osaka]. Here are some frequently asked questions and their answers from the venue. ■ Is it cheaper to make machined parts as castings? It depends on the quantity. Switching from machining to casting is cost-effective for orders of five or more. The more pockets and cutouts in the shape, the more material becomes chips, so using a casting closer to the final shape can reduce the amount and time spent on machining. We will provide estimates for both machining and casting side by side. ■ Can you make parts if there is no 3D data and only old drawings? Yes, we can. If we have the actual part, we can measure its shape using 3D scanning and create data for mold design. We receive requests for replacement parts for discontinued products and for reproducing parts without drawings. ■ Can you process castings made by other companies? Yes, we can. As a casting manufacturer, we are accustomed to individual differences and variations in machining allowances. We process using 15 five-axis machining centers and confirm dimensions with a three-dimensional measuring machine before shipping. We can accommodate orders starting from one piece, and prototypes can be shipped in as little as two weeks. If you send us drawings or photos of the actual parts, we will respond with feasibility and a rough estimate.

In August 2026, we introduced the optical 3D scanning system "NIMBLETRACK Gen2." With traditional calipers and height gauges, it was difficult to confirm the "overall shape of the product," but now we can visualize it using a color map by comparing it with 3D CAD data. 【Material Quality Assessment Before Machining】 We scan materials after casting to detect any excess or shortage of machining allowances, mold misalignment, core misalignment, and warping before processing. This allows us to identify defective materials before they are fed into the machining equipment, preventing waste of machine time, tools, and setup. We can also perform similar pre-processing assessments for materials cast by other companies. 【Physical Replication of Parts Without Drawings】 No markers are needed, and it is wireless, allowing us to scan the actual object directly. We handle everything in-house from data creation to wooden pattern production, casting, and machining. 【Aging Management of Wooden and Metal Molds】 We regularly measure mold wear and deformation, contributing to the prevention and maintenance of casting defects. *Strict dimensional tolerance guarantees will continue to be performed using traditional three-dimensional measuring machines. Even without drawings, you can consult us with just photographs of the actual item, along with dimensions, materials, and quantities.

We will be exhibiting at "Monozukuri World [Osaka] 2026," which will be held from October 7 (Wednesday) to 9 (Friday), 2026, at Intex Osaka. ■ Dates: October 7 (Wednesday) - 9 (Friday), 10:00 AM - 5:00 PM ■ Venue: Intex Osaka, Halls 1-6 ■ Booth Number: 57-13 At our booth, we will introduce the following themes along with actual samples of aluminum and copper alloy castings: 【Cost Reduction through Process Change】 From machining to casting (shortened delivery time for 3 or more pieces, cost reduction for 5 or more pieces) / From die casting to sand casting (for prototypes and small lots) 【Lightweight and Thin-Walled Design】 Material substitution from cast iron to aluminum castings, thinning down to a minimum of 2mm 【Small Lots and Prototypes from One Piece】 Over 500 prototype achievements annually, prototypes shipped in as little as 2 weeks 【Solutions for Casting Defects】 Over 100 achievements in resolving issues such as shrinkage cavities and poor filling No drawings are necessary. If you bring photos of the actual item or approximate dimensions, materials, and quantities, we will provide guidance on the process on the spot. Please feel free to stop by booth number 57-13.
