Green sand molding
- Casting production that is worker- and
environment-friendly, aiming for net-shaping,
thinning/weight reduction, and zero defects
Sinto has developed unique, world-renowned technologies such as V-Process, SEIATSU, and aeration, and we have developed a rich product lineup backed by extensive experience and expertise. We provide our customers with the right equipment and comprehensive solutions for better casting production. Aiming for net shape, our superior molding technologies make it possible to produce high-precision molds that achieve near-net shape and thinning/weight reduction.
More recently, we’ve also been aiming for zero defects, employing IT solutions to prevent quality problems at every step. This gives us the numerical data we need to visually track the status of each process and keep quality variations to a minimum.
Net shaping and thinning/weight reduction through better casting production
Providing thinner, lighter products
Mold production with highly precise mold dimensions, making thinner products possible
Sinto delivers superior molding performance—even with thin, complex shapes.
Effects
- Lighter-weight castings
Usage example
Motor cooling fin
Benefits of near-net shape
Reduced draft
Reduce casting material weight and the need for machining in subsequent processes
Effects
- Less cutting in following processes
Less time, lower cutter costs - Less energy used for melting
Our Good Casting System™ uses net shaping
and thinning/weight reduction to achieve better casting production
SINTO SMART FOUNDRY
Proposals to achieve zero quality defects for better casting production
From sand treatment to molding, cores, pouring, cooling, and after treatment, Sinto evaluation sensors collect manufacturing data from every stage of the casting process for advanced digitization, collection, and visualization. Understand the situation in real time and analyze the data to identify the root cause of defects.
Benefits
（1）Minimize variation for more reliable casting quality
（2）Fully-automated processes keep defects from moving on to the next process, improving casting quality
Evaluation equipment
Evaluation equipment monitors each process.（3）Visually track numerical quality data

Better casting production starts with better sand
There are three criteria for quality green sand (adhesiveness, fluidity, stability), so its micro-properties must be properly managed to ensure that only particles that meet all three are being supplied.
Taken to the extreme, this means controlling the properties of every grain of sand. If you can see the sand particles, you know how the casting is going to turn out. Sinto sand treatment supports the production of better castings.
Green sand molding systems
For superior-quality molds
Sinto’s extensive lineup of molding systems is built on our proprietary core technologies. We can provide the ideal molding machine to create superior-quality molds to match the product size, shape, and production criteria you need.
We propose molding systems that include evaluation devices, allowing you to check the quality of your molds for better casting production.
Core molding systems
Core molding systems designed to create a low-odor, operator-friendly work environment
Cores are at the heart of casting. At Sinto, our systems don’t just produce high-quality cores, they also minimize odors so they’re better for workers and the environment. Our total core systems provide automated core operations, labor-saving engineering, core sand reclamation systems, and more for cold box molding, inorganic cores, and shell molds.
Pouring systems
Precision pouring systems that keep pouring-related defects to a minimum
From inflow to pouring, we ensure the safety and reliable operation of our customers’ casting production. Our cutting-edge inflow, transfer, and pouring systems provide automated operations, labor savings, an improved work environment, increased quality, and lower costs.
Cooling systems
Optimized product cooling for higher productivity and better quality
Sinto offers optimized product cooling systems that boost productivity and increase quality by adjusting cooling time to match the needs of every product.
After treatment equipment
For high-quality, efficient finishing of castings
Our after treatment lineup includes equipment that crushes molds and separates products from sand before cooling them, as well as shot blasting for sand removal.
We offer products that are tailored to each customer’s product size and production requirements.
IoT solutions
Using IT in pursuit of zero defects
Sinto uses IT to create systems that reduce quality defects at each casting production process through sensing of manufacturing conditions, digitization, data collection, and more.
We also offer a variety of IoT-powered preventative maintenance systems to keep equipment running safely and reliably.
Environmental solutions
Worker- and environment-friendly casting production
We contribute to the evolution of casting production that is worker- and environment-friendly. We work to achieve a clean, comfortable factory environment that is easy to work in.
