QT12 Cement hollow block molding machine

Our concrete block making machine is the core machine used for producing blocks/bricks.

The technology is introduced from German Hess. This machine is automatic and multi-functional. It can produce large varieties and various sizes of products. It can produce concrete blocks, bricks, hollow block, insulated block, solid bricks, paving slabs, interlocking pavers, paving stone, retaining stone, curb stone etc.. You just need to replace the mould. The moulds are designed according to your requirement.

concrete block making machine is automatic and operated by the PLC controller. The main electrical appliances all use foreign famous brands such as the Transducer (Japanese Panasonic), Breaker and Contactor (Japanese Fujiand Panasonic) etc.

For the motors we adopt the SHANGHAI brand, a famous brand in China, We provide one year guarantee for our motors.


The conveyor belt has 5 layers and 12 mm thickness so it is very Strong, thus to make sure it has a long life.


The mold is made of 16 manganese, not the cast steel (No. 45 steel), also not common A3 iron plate as some companies) and will be processed by the heat treatment which will prolong its life (the mold can be used for 150,000 times) (MOST COMPANIES IN QUANZHOU CAN ONLY USED FOR 100,000 TIMES)

 Brief Introduction

1. Special material storing system: The material storing unit can move forward and after. And it is very easy to clean the material adding hopper. The integrative design can ensure the accuracy of material supply, so the blocks/bricks can have the same density.
2. Special material feeding system: It adopts the technology of active forcing arch acentric feeding material. Under the help of the material-feeding bar, the material in the mould box can be instantaneously spread evenly and meet the requirement of being quick but even.
3. Integrated oil system: It adopts the model of international standard. So the system has the specialties of long lifespan, good weather resistance and low energy consumption. Importing important components is another guarantee of good quality. The reasonable design of oil line can make the energy utilization rate reach 90%.
4. Intellectualized PLC control system: It has a Human-Machine Interface which means the operator can totally control the machine without any training. It can also automatically operate, analyze compaction, adjust material feeding and diagnose the malfunction. It is easy and safe to use.
5. The whole equipment adopts the durable design and advanced weld craftwork is used to make it consistent and durable.
6. Conjunction type of double pigment spreading device (color system): they can be combined according to different production needs. It also serves several purposes: it can produce 6~19cm single color or double color products.
7.Use good quality brand for important parts:Use SIEMENS brand motor and PLC,Taiwan electricity and hydraulic element.
Mould: We Use the manganese steel with high heat treatment as raw material,mould’s rockwell hardness for 60 degrees, the life is twofold compare with a traditional mold, the cost but only up to 30%.
