Accuracy verification and prototyping through weight reduction [Digital cast case study]

Accuracy verification and prototyping through weight reduction [Digital cast case study]

Zero yen mold cost for rapid casting. For prototype and verification of metal parts, leave it to Castem's mold-less casting digital cast.

**Manufacturing Method** Digital Cast **Content** Verification of whether it is possible to achieve precision in robot control by reducing weight. Additionally, there is an interest in prototyping with topology shapes, so we propose digital casting without molds, which can accommodate from one piece. **What is Digital Cast?** A manufacturing method that creates resin models using a 3D printer and then produces metal products following a process similar to lost-wax precision casting. Castings can be produced in as little as one week, starting from a single piece. We offer proposals that are beneficial for development and prototyping. If you have parts under consideration for weight reduction or shape changes, please feel free to consult with us. ↓ Insert link to related page ↓ https://castem-digitalcast.com/ ～～～～～～～～～～～～～～～～～～～～ Industry: Industrial Robots Material: AC4C

"Transitioning from cutting processing to new methods" - Improved mass production and significant cost reduction.

"Transitioning from cutting processing to new methods" - Improved mass production and significant cost reduction.

Transitioning from machining products to lost-wax casting!

"Switching from Machined Products to Lost Wax Casting!" ✅ Improved Lead Time ✅ Cost Reduction ✅ Comprehensive Quality Measures Previously, we used machined products, but by switching to lost wax precision casting, we have improved mass production capabilities and achieved better lead times. Additionally, by reducing material weight by over 100g through thinning, we have also made cost reductions possible. We have implemented thorough quality measures, such as addressing porosity by ensuring uniform wall thickness and preventing burrs by creating recesses. We have received many inquiries from customers considering the switch from machining to lost wax precision casting, particularly regarding cost aspects. Depending on the desired size and application of the parts, we can also suggest other methods such as MIM (Metal Injection Molding) and Digital Casting (mold-less casting using 3D printed models). For any inquiries regarding metal parts, please feel free to consult with Castem.

Turbine impeller parts [3D printer utilized for digital casting]

Turbine impeller parts [3D printer utilized for digital casting]

Impeller and turbine parts are also available for short delivery times.

Achieve short delivery times with the "Digital Cast" method, which uses models created by a 3D printer for casting! For large parts with a diameter of φ380, traditional mold production required 1 to 2 months, but with the Digital Cast method, cast products can be produced without molds starting from just one piece, resulting in significant improvements in delivery times. Additionally, we can accommodate special materials such as heat-resistant steel and duralumin. *The product in the photo is SCS13. 【What is Digital Cast?】 When considering costs and delivery times, traditional casting methods that require mold production are not a viable option for mass production. Therefore, we propose mold-free casting with Digital Cast, using the catchphrase "Just make it if you need it, starting from one piece!" With no need for molds and a mold cost of 0 yen, we have a proven delivery record of as short as one week, and we can custom-make cast products starting from just one piece. Since the original shape is a 3D printed item, we can accommodate complex shapes and hollow products that cannot be manufactured with molds. This method is adopted in numerous industries, including aerospace, shipping, automotive, precision machinery, industrial equipment, medical, and construction, and we cater to requests for metal parts from both corporate and individual customers.

What can be done with lost-wax precision casting?

What can be done with lost-wax precision casting?

Hollow and complex three-dimensional shapes / Cost reduction / Reduction of processes / Compatibility with a variety of steel types… Introducing the strengths of lost-wax precision casting.

The lost wax precision casting method involves injecting wax into a mold to create a product model, coating it with ceramic to form a casting mold, and then casting to produce metal parts. Its strengths are as follows: ✅ Hollow and complex three-dimensional shapes ✅ A diverse selection of over 70 steel types (including iron, stainless steel, copper, aluminum, and special materials such as super duralumin) ✅ Cost reduction achieved through meat removal considering productivity ✅ Time savings through reduced number of processes ✅ Small lot production of various types (from dozens to thousands per lot) ✅ Affordable aluminum molds that can be used semi-permanently ✅ Capable of handling large items from a few grams to 30 kg (preferred size is 30 to φ300 mm) "I want to integrate multiple parts," "I want to increase strength," "I want to reduce costs compared to machining." "Machining and welding require multiple processes for a single part, leading to increased costs and time..." We propose optimal materials, shapes, and methods tailored to your concerns and requests. *For a list of materials and tolerance tables, click here* →https://www.castem.co.jp/technology/lostwax/ Please feel free to consult us through our website.

It is possible to cast complex three-dimensional shapes using super duralumin "A7075".

It is possible to cast complex three-dimensional shapes using super duralumin "A7075".

Recommended for aerospace components and robot parts with weight reduction and increased strength. Enhance strength and propose bold shapes to reduce costs.

The ultra-high-strength aluminum material, super duralumin "A7075 (cast)", is now part of our original casting material standards! It can be used in lost-wax precision casting and mold-less casting "Digital Cast". "Wanting lightness and strength, but titanium is expensive. I want to keep costs down..." We solve such concerns. While possessing the unique lightness of aluminum, its tensile strength is close to that of stainless steel "SCS13 (equivalent to SUS304)". It is suitable for aerospace components and robotic parts where lightness and strength are required. With lost-wax precision casting, which excels in hollow and complex three-dimensional shapes, we can lead to cost reductions through optimal shape proposals. ★ For a detailed description of A7075, please see the attached image. ★ For compatible materials, click here: https://www.castem.co.jp/technology/lostwax/

How to manufacture aerospace components with special materials?

How to manufacture aerospace components with special materials?

Would you like to try manufacturing parts that are currently being produced through cutting and welding at a lower cost and with a shorter delivery time?

Would you like to try manufacturing parts that are currently being produced through cutting and welding at a lower cost and with a shorter delivery time? The parts in the image were originally made by machining two separate components and then welding them together. Due to the special material known as Inconel 625, it was necessary to source from overseas processing companies, which increased costs. Additionally, this material is prone to work hardening, making machining very difficult. However, all of these issues can be resolved with the mold-free, multi-material casting method called Digital Cast! The key points of Digital Cast are as follows: ✅ The shortest delivery time is one week ✅ More than 70 types of materials (casting materials) are available ✅ Production is possible from just one piece ✅ No mold costs We also welcome inquiries for prototypes aimed at mass production or small-lot production! We will flexibly respond to your needs, so if you have parts you are considering for weight reduction or shape changes, please feel free to contact us. What is Digital Cast? It is a method of producing metal products by creating a resin model with a 3D printer and then following a process similar to lost-wax precision casting. Castings can be produced in as little as one week and from just one piece. We offer proposals that provide benefits even in development and prototyping.
