outsource

 Safely outsource to us


Rest assured by outsourcing to us. We can use our reliable integrated production line to assist with your processing needs should the efficiency of your mass production line be insufficient or you need service parts after mass-produced parts have been discotinued.

We can;
●Help boost the efficiency of your mass production line
●Manufacture service parts after mass produced parts

Short-term processing support

 Short-term processing support


We provide backup so that you won't lose any orders. We offer processing support in the short term to cover you during peak production periods, or for when your production capacity cannot keep up with an unexpected increase in orders.

This gives;
●Production assistance during the "busy" season
●Help in alleviating back-orders

We also handle small lots

 We also handle small lots


We handle all types of small lot orders. We manufacture prototypes for development teams tasked with new projects and ongoing testing. We also manufacture test pieces for launching new production lines.

Our capabilities include;
●Prototypes(forged and machined round bar products)
●Development projects

Round bar machining

 Round bar machining


When you're suddenly in the need for a spare part but have already disposed of the mould to make it (and it's too late to make a new mould), we have the technology to machine round bar and can produce a finished product. We can handle small lots with a short turnaround.

This includes;
●Spare parts
●Aftermarket parts

Partial processing support

 Partial processing support


If there is a glitch in your production line due to machinery problems and immediate recovery is not possible due to a delay in finding parts for repair, or if repairs are taking time, then that portion of processing can be outsourced to us.

We offer;
●Immediate response when production is over capacity
●Backup in times of equipment trouble

Boosting operational efficiency

 Boosting operational efficiency

We are able to quickly build an optimal production line that suits customer specifications

Outsourcing boosts operational efficiency by reducing costs and without having to possess excess facilities.Yuasa is equipped with both a crankshaft mass production line and a prototype production line. We can build an optimal production line that suits the needs of our customers.

Mass production line:●Mass-produced products(repeated products)
              ●Large-lot spot production(processing support products)
Trial production line:●Prototype●Spare parts●Small-lot spot production
             ●Blank processed products●Processing of test pieces for launching a new line

Selection & focus

 Selection & focus

Take advantage of our sophisticated technological capabilities

Yuasa has advanced technologies which have been developed through metalworking, primarily the manufacturing of a wide range of crankshafts for cars,ships,and trains. We aim to contribute to your company's strategy to select and focus on which operations you want to keep in-houce and which you choose to outsource.

●Special processing:Gear cutting processing(spline/sprocket processing)/fillet roll/Induction hardening, etc.


Low cost

 Low cost

We can offer low-cost mass production because we are a specialized manufacturer

Rather than manufacturing parts in-house when manufacturing products that require many different parts, the best option for keeping costs down is to outsource the mass production of parts to a specialized manufacturer.
As a specialized manufacturer, Yuasa's highly efficient production line can achieve low cost.



Technical capabilities

 We can machine axis components up to 4,000mm in length.


Yuasa boasts facilities capable of machining up to lengths of 4,000 mm. We can provide machining for any type of shaft-shaped component. Longer components require a greater level of precision. Yuasa achieves this through our vast experience and technical knowhow.
