This is one of our projects to deal with client from chemical industry. Their production department was using 4 silo tanks manually to produce their products. This client approached our company to improve their current manual process which caused dissatisfaction of product quality.

We proposed a custom built PLC control system to overcome their problems. The architectures of this system will improve product quality and production efficiency. With the high accuracy measured weight, the product quality has been greatly improved. The quality has reached almost same level with desired quality.

This system has preset weight material and weight quantity function. It means this system has ability to store numbers of recipe. Supervisors and operators are no longer required to re-provide all the quantities and material codes each time they plan to start a new batch. When they are ready to run a new batch, they are just need to recall the product recipe and push the start button. The system is then run automatically until the process ends. All the data will be logged when the process is ended. The logged data can be used as reporting purpose.

Lastly, we have add-on some precaution steps to minimize human errors.
