YUMO PARTS

What YUMO PARTS does

YUMO PARTS (ユモパーツ), operated by Yumoto Electric Co., Ltd. (湯本電機株式会社), is a Japanese precision prototyping and small-batch manufacturing service provider founded in 1940 and headquartered in Osaka, Japan. The company specializes in CNC machining and 3D printing of custom metal and resin parts for design and development engineers across more than 3,000 customer companies spanning aerospace, semiconductor equipment, robotics, and academic research. In FY2026 (year ending May 2026), the company generated 17 billion JPY in revenue with a 10-year CAGR of 12.3% and employed 137 people on a consolidated basis (75 in Japan).

YUMO PARTS operates from an ISO 9001:2015-certified Osaka headquarters equipped with five-axis machining centers, multi-axis CNC lathes, and coordinate measuring machines, complemented by a manufacturing facility in Tay Ninh Province, Vietnam, that supports higher-volume production runs of 20-1,000 units. Its service portfolio covers CNC machining and 3D printing (FDM, SLS, SLA) across 200+ metal and resin materials, including difficult-to-machine metals such as titanium, molybdenum, and stainless steels, plus 30+ post-processing surface treatments managed through a single order channel. Notable technical capabilities include a hybrid metal 3D printing workflow with CNC secondary finishing for aerospace-grade surface tolerances, and a newly added BAMBU LAB H2D PRO FDM printer providing approximately 1.5x faster throughput. The company processes more than 76,738 drawing quotations annually, the data from which supports its value-engineering (VE) proposal capability.

Revenue is generated primarily through per-order custom quotations for one-off to small-lot prototype parts (1-1,000 units), with prices varying by material, complexity, quantity, and lead time. YUMO PARTS employs a web-based direct go-to-market with a proprietary two-hour response SLA, multilingual support in Japanese, English, Chinese, and Vietnamese, and embedded engineering consultation. Recent strategic activity includes a 2026 factory relocation with nine new machines, the introduction of the BAMBU LAB H2D PRO printer, deployment of a website AI chatbot, the first new graduate recruitment cycle, and the Japan-Vietnam dual-hub manufacturing model, all of which point to continued capacity and capability expansion.

Core offering

YUMO PARTS provides custom CNC machining (切削加工) and 3D printing (3Dプリント) services for prototype and small-lot production parts in over 200 metal and resin material grades, supported by engineering consultation and value engineering (VE) proposals. The company serves R&D and design engineering teams with order volumes from 1 piece to 1,000 units, with sample lead times as short as 1 week from the ISO 9001:2015-certified Osaka factory and a Vietnam facility for scaled production.

Product overview

YUMO PARTS is a precision prototype engineering partner operated by Yumoto Electric Co., Ltd., offering a portfolio of two primary manufacturing services — CNC machining (切削加工) and 3D printing (3Dプリント) — supported by design consultation and quality management add-on services. CNC machining handles over 200 metal and resin materials (aluminum, stainless steel, titanium, PEEK, POM, etc.) with surface treatment options (anodizing, plating, polishing, etc.) from an ISO 9001:2015-certified Osaka factory. 3D printing covers FDM, SLS, and SLA technologies across metal and resin materials (aluminum, SUS316L, titanium, PEKK, ULTEM, Onyx, PA12, etc.), with a newly introduced BAMBU LAB H2D PRO for ultra-fast FDM printing. Design & Machining Consultation (VE提案) assists with material selection and manufacturing method optimization based on accumulated quoting data. A 24/7 AI chatbot on the website handles text-based visitor inquiries. Production spans two factories (Osaka HQ and Vietnam), with the Osaka plant achieving standard lead times from 1 week and minimum orders from 1 piece.
