We want to control motion, simplify complex operations,
and integrate power into limited spaces.
Sanwa Seiki brings these challenges to life using pneumatic and hydraulic technology.
Even if your application isn’t fully defined yet, that’s okay.
From the conceptual stage to mass production, we’ll work together to find the way to make it happen.
Case.01 Hydraulic Solution Proposal
We meet the demand for multi-axis control and complex motion within limited space.
| Customer Challenge | Smooth boom movement was sometimes not achieved in construction machinery. |
|---|---|
| Our Approach | We subdivided the movement of components within the hydraulic circuit, implemented measures to prevent hunting, and revised the circuit. This achieved smooth movement while avoiding significant cost increases. |
| Effect | Implementing hunting countermeasures enabled horizontal deployment to other models. As a result, it also contributed significantly to quality improvement. |
Case.02 Hydraulic Solution Proposal
From the conceptual stage of new lines or equipment introduction, we build hydraulic mechanisms tailored to on-site conditions.
We also flexibly handle redesigns and updates of existing equipment to realize the optimal system for your site.
| Customer Challenge | Hydraulic motors used in construction machinery exhibited slight inertial movement after stopping, failing to respond to minute movements. |
|---|---|
| Our Approach | We designed a mechanism adding a locking device to the hydraulic motor, ensuring it stops immediately after operation ceases. |
| Effect | Stopping responsiveness improved, significantly enhancing the product’s marketability as construction machinery. |
Case.03 Pneumatic Solution Proposal
For equipment requiring complex flow path switching and prevention of malfunctions, we propose high-precision circuits utilizing pneumatic technology.
| Customer Challenge | To comply with exhaust gas regulations, a new mechanism was needed to switch exhaust gas flow paths. |
|---|---|
| Our Approach | We developed and proposed a new switching valve incorporating water channels, using materials capable of withstanding high-temperature environments. |
| Effect | Contributed to engine development meeting new exhaust regulations and enabled deployment in next-generation models. |

Even if your idea is still in the conceptual stage, that’s no problem.
Feel free to share your challenges and requests with us, such as “We want to achieve this kind of motion”, “Our current parts are difficult to adapt.” and so on.
Our sales and technical staff will discuss your needs together, clarifying the usage environment, objectives, and required performance.
No problem if you do not have any drawing / blueprint. Please share your ideas and concepts to the best of your ability.
We propose structures and functions utilizing pneumatic / hydraulic systems to address your concerns. If needed, we accompany you from the initial design stage to explore optimal specifications.
Once the structure and specifications are finalized, we present the prototype production details, costs, and delivery schedule.
We proceed with formal orders only after you are fully satisfied.
Our in-house design, machining, and assembly departments collaborate to meticulously produce prototypes.
We can accommodate requirements including machining precision and operational checks to meet specified performance.
After delivery, we support performance verification and testing under actual usage conditions upon request.
If improvements are needed, we perform readjustments and re-prototyping for mass production readiness.
Once the final specifications are confirmed, we begin mass production.
We support your product manufacturing with stable quality and delivery times.
“We have a concept, but haven't drawn up detailed blueprints yet.”
“We want to achieve this motion, but do not know the right structure.”
At Sanwa Seiki, we've handled numerous consultations starting from these early phases.
After carefully listening to your application, environment, and target specifications,
we swiftly propose structures and create prototypes.
Since we have an in-house system capable of handling everything from design to prototyping and mass production,
we are confident in our development speed and flexibility.
As your “technology-proposing partner,” we explore the optimal approach for your purpose together,
not limited to pneumatic or hydraulic solutions. Feel free to consult with us first.
Our Design and Development Department, the core of our development efforts,
employs over 50 engineers.
Specialists across diverse fields, mechanical design, control design, product development, software operations, and server management,
work together as a team on product development.
Our strengths lie not only in flagship products like Japan’s only air brake compressor and our cab tilt device boasting a 100% market share, but also in our ability to propose technologies applicable to new industries and emerging applications.
During development and prototyping, we flexibly accommodate customer attendance.
To ensure you can confidently monitor the development process, we do not impose special rules and disclose the process in a manner that aligns with your preferences as much as possible.
