In January 2018, Raytone Company successfully delivered a QT4-28 block making machine to Uruguay, marking another milestone in our global expansion. The machine was shipped to Mr. Cristian Gibert, a valued client, who also requested stainless steel and galvanized sheets to be loaded together in a 20-foot container. Over the following months, Mr. Cristian further expanded his operations by purchasing an electric wheel loader and an electric forklift from us. This article delves into the features, benefits, and technical specifications of the QT4-28 concrete block making machine, a game-changer in the construction industry.

What is the QT4-28 Block Making Machine?
The QT4-28 concrete block making machine is a semi-automatic, high-performance machine designed for producing a wide range of concrete blocks, including hollow blocks, solid blocks, pavers, and more. It is an upgraded version of the QT4-40 manual block machine, featuring advanced automation and improved efficiency. With its one-button operation, the QT4-28 is perfect for both beginners and seasoned professionals in the brick manufacturing industry.

Key Features of the QT4-28 Block Making Machine
1. Fully Automatic PLC Control System
The QT4-28 is equipped with a Programmable Logic Controller (PLC) that ensures seamless operation. With just a single button press, the machine can form blocks, making it incredibly user-friendly. This feature has earned it the nickname “One Button Block Forming Machine.”
2. High Production Capacity
The QT4-28 boasts an impressive daily production capacity of 4,114 pieces of 8-inch hollow blocks. This high output makes it ideal for large-scale construction projects, ensuring timely delivery and reduced labor costs.
3. Versatile Block Production
This machine can produce a variety of block types, including:
- Hollow blocks
- Solid blocks
- Pavers
- Interlocking bricks
The adjustable molds allow for customization, enabling users to create blocks of different shapes and sizes to meet specific project requirements.
4. Robust and Durable Construction
Built with heavy-duty materials, the QT4-28 is designed to withstand rigorous use. Its sturdy frame minimizes vibrations during operation, ensuring stability and longevity. This durability makes it a cost-effective investment for long-term use.
5. Energy-Efficient Design
The QT4-28 is powered by energy-efficient motors, including:
- Bottom vibration motors: 2 sets of 3 KW each
- Top vibration motor: 1 set of 2.2 KW
- Raw materials distributing motor: 2.2 KW
- Top mold fall-down motor: 1.1 KW
- Block mold lift motor: 3.0 KW
These motors work in harmony to deliver optimal performance while reducing energy consumption.QT4-28 Block Making Machine
Advantages of the QT4-28 Block Making Machine
1. Labor Savings
Compared to its predecessor, the QT4-40 manual block machine, the QT4-28 requires fewer workers. With just three operators—one for the mixer, one for the host machine, and two for transporting formed blocks—the machine significantly reduces labor costs.
2. Enhanced Efficiency
The addition of a hopper and a raw materials distributing device streamlines the production process. These features allow the machine to work seamlessly with a belt conveying system, ensuring a continuous supply of raw materials and minimizing downtime.
3. Consistent and High-Quality Output
The QT4-28’s advanced vibration system ensures uniform compaction of raw materials, resulting in blocks with precise dimensions and superior strength. This consistency is crucial for meeting industry standards and ensuring the durability of construction projects.
4. Cost-Effective Investment
With a price range of 7,900to12,000, the QT4-28 offers exceptional value for money. Its automation capabilities and high production output translate to a quick return on investment, making it a smart choice for businesses looking to scale their operations.
