If you are looking for a place that can process castings and forged products, please consult Mutsumi Industries.

Those looking for places that can process castings and forged products due to the reasons that 'casting and forging are difficult to work with chucks' and 'castings, in particular, dirty the machines.'

Reasons why subcontractors dislike it... "Castings and forgings are difficult to chuck." "Castings, in particular, dirty the machines." ■□■If you have such concerns and are looking for a place that can process castings and forgings, this is a must-see!■□■ ■Leave the processing of castings and forgings to Buzukogyo!

We will procure parts, jigs, and processed products from China.

We will procure parts, jigs, and processed products from China.

Even a company with three employees can place orders and request processing in China. It's an era where relying solely on domestic outsourcing will not allow you to survive.

Takeuchi Machinery Manufacturing Co., Ltd. is committed to providing better and more affordable products to our customers by conducting machining domestically while closely collaborating with processing companies in China. Parts and products manufactured locally undergo pre-shipment inspection by our local staff. Subsequently, all products received from China are rigorously inspected at Takeuchi Machinery Manufacturing Co., Ltd. using three-dimensional measuring instruments. Any defective products are immediately reworked and shipped from Takeuchi Machinery Manufacturing Co., Ltd. This is a new business style that only Takeuchi Machinery Manufacturing Co., Ltd., with its 80 years of experience in parts processing, can offer. 【Features】 - Order lots can be accommodated from a single piece to mass production. - We can provide services identical to those in Japan, including vacuum hardening, carburizing hardening, tuftriding treatment, nitriding treatment, various plating, and titanium coating. - Transportation methods from the local area can include air freight or shipping, tailored to weight, delivery time, and budget. - Air freight can achieve astonishing next-day delivery, while shipping takes approximately 14 days. - We can handle machining from small sizes of 30×30 to large sizes like 2000×2000. - We also undertake inspection-only services locally.

A must-see for those struggling with parts procurement during the COVID-19 pandemic!

A must-see for those struggling with parts procurement during the COVID-19 pandemic!

One-stop solution for challenges in parts procurement such as quality, cost, and delivery time. Single item requests are also welcome.

Our company leverages its know-how as a former manufacturer of labor-saving machinery to provide a one-stop solution from design and development to procurement, prototyping, and mass production. We can design considering the manufacturing methods according to the necessary functions, and we have a procurement network both domestically and internationally, contributing to the reduction of selection man-hours and costs for procurement sources. Since we realize manufacturing that does not rely on the skills of workers, including quality control, we can stably supply high-quality and high-precision parts and finished products over the long term. 【We solve the following problems】 - Parts can no longer be procured due to the closure of the procurement source. - Quality is being affected due to aging and personnel shortages. - We are struggling to cope with extended lead times and increased transportation costs from overseas procurement. - We cannot communicate directly with the production site, making it difficult to convey changes in drawings or specifications. - It is cumbersome to create 2D drawings for one-off products. *For more details, please refer to the PDF document. Feel free to contact us as well.
