The Automatic Shrinking Machine Solution by Coolmay EX3G Series HMI/PLC All-in-One

This article mainly introduces the application of Shenzhen Coolamy Technology HMI/PLC all-in-one(product model: EX3G-100HA-44MRT-2AD-K) in the shrinking machine. This application realizes the flexible control of the shrinking machine. And the user can program and modify the automatic operation process according to their requirements. The shrinking machine is suitable for leather, wool, chemical fiber, pure cotton, blended, etc.. It can also be used for Washing, shrinking, soft processing of Knitting, wool, woven, textile. This application is an intelligent operation. It is very easy to use and saves a lot of cost.


The shrinking machine is mainly used for the shrinking work of fiber fabrics such as wool. The general shrinking includes washing, dehydrating, drying and other process. The whole process requires manual participation, and each different process needs to use different machines. The entire process is time-consuming and labor-intensive, and the efficiency is difficult to improve. The use of the shrinking machine can integrate various processes such as washing, softening, drying and fixing on one machine. And using Coolmay HMI/PLC all-in-one as the controller can realize the free editing of the process and improve flexibility in machine use. Ultimately, the purpose of improving work efficiency and reducing labor costs is achieved.

Before and after the upgrade process

Traditional fluff processing process:

- Shrinking machine processing flow controlled by HMI/PLC all-in-one:

It can be seen that the use of the shrinking machine greatly simplifies the processing flow, integrates the past 4 to 5 processes into one operation, and automatically processes the clothes without manual intervention after putting clothes.

Operation interface

EX3G-100HA-44MRT-2AD-K has a beautiful interface, a large screen and a clear display. The shrinking machine can use different processing programs depending on the type of clothing.

The screen can set up a processing program for each material to support up to 27 steps, each step can be freely selected 15 processing processes and can set the execution time. During the shrinking machine working process, the temperature in the barrel can be controlled to be maintained within the set range.

General use process of the shrinking machine

After booting, select the corresponding clothing program. If you need to use the new parameters, you can directly modify the process type and working time of each step. After the parameters are modified, click “Data Settings Save” to save the current parameters to the machine, then Put the cloth into the barrel, close the front door, and click Start to start the automatic process. After the automatic process is completed, a message will be sent to inform the user.

The front door of the shrinking machine has an inductive position switch. When the front door is sensed, the machine will stop working to avoid accidents.

The shrinking machine after refining by using a coolmay HMI/PLC all-in-one

Ten inch HMI/PLC all-in-one has a large screen, clear display. Graphical operation interface of the HMI/PLC all-in-one is intuitive and easy to understand.

Economic benefits realized by the modified shrinking machine:


After using the shrinking machine, one person can operate 3-5 machines, can process 9600 pieces of clothes (calculated by 8 hours a day).The shrinking machine can process one-cylinder clothes in 30-40 minutes, while the traditional process requires more than 90 minutes to complete a process. The efficiency is greatly improved.

* Energy saving and environmental protection:

1.Power saving, 4.4 kWh per hour (general condition).

2.Water saving, only 20 kg of water is needed for each cylinder of clothing produced.

3.Save steam, save 50% steam than traditional processes.

4.Provincial syrup, only 30% of traditional craft syrup.
