Can hydraulic block machines withstand -30°C frost without cracking blocks?

        When the Siberian cold current sweeps across Northeast China, construction sites often face the problem of cracked blocks due to freezing, causing project delays. The extremely cold hydraulic block forming machine launched by HONGJIA MACHINERY, with its -30℃ low-temperature anti-freezing technology, is rewriting the production rules of building materials in cold regions. In a certain affordable housing project in Inner Mongolia with a temperature of minus 35 degrees Celsius, this equipment has been operating stably for 72 consecutive hours. The freezing crack rate of the blocks has dropped from the industry average of 15% to 0.3%, providing a reliable solution for construction in extremely cold regions.

HONGJIA MACHINERY - With the power of hydraulics, we build the ultimate firmness

HONGJIA has developed differentiated product lines for extreme working conditions

        The HJM-F series extreme cold type: It adopts an electrically heated hydraulic oil circuit and low-temperature alloy molds. It can still maintain the fluidity of the hydraulic system in an environment of -30℃ and has been successfully applied in winter construction projects in Heilongjiang, Xinjiang and other places.

        The HJM-S series standard type: Covering the conventional working conditions from 0℃ to 40℃, it automatically adjusts the pressure parameters through the intelligent temperature control module and has a market share of 68% in North China.

        The HJM-H series Plateau type: The sealing structure is optimized for the low-pressure environment of the Qinghai-Tibet Plateau to ensure stable forming pressure at an altitude of 4,500 meters, providing support for the construction of the Sichuan-Tibet Railway.

Why did the factory choose HONGJIA?

        In the past, we had to suspend production for three months in winter. Now, HONGJIA's equipment enables us to work all year round without a break. The person in charge of a building materials factory in Liaoning Province has done the math: Although the unit price of the extremely cold model is 20% higher, the revenue brought by the increase in winter production capacity can be recovered within eight months. More importantly, the blocks it produces have reached the F300 grade in the freeze-thaw cycle test (no damage after 300 freeze-thaw cycles), meeting the requirement of a 100-year lifespan for buildings in extremely cold regions.

The technological leap from "being able to produce" to "producing well"

        We not only need to solve the problem of freezing and cracking, but also make the equipment adapt to the environment by itself. HONGJIA's R&D director disclosed at a recent industry forum that the team is testing a new generation of adaptive hydraulic systems. This system senses the ambient temperature in real time through over 200 pressure sensors and automatically adjusts the viscosity of the oil circuit and the forming rhythm. "It's like equipping the machine with a 'climate-sensing nerve'. In the future, it will become a reality to produce blocks of the same quality with the same equipment in Mohe and Sanya."

A production miracle in the cold winter

        In a coal mine shantytown renovation project in Hulun Buir, the HONGJIA extreme Cold model set a production record of 12,000 blocks in cold regions in a single day. The project manager of the construction party said, "Traditional equipment will break down due to the solidification of hydraulic oil at -15℃, while HONGJIA's machine can even start working directly in the snow. The workers all call it the 'snow mammoth'." This project was commended by the local government as a "Winter Construction Benchmark Project" for being completed 45 days ahead of schedule.

The dual evolution of green and intelligent

        Facing the "dual carbon" goals, HONGJIA has initiated an energy efficiency upgrade plan for its hydraulic system. The latest test data shows that by recovering braking energy and optimizing the oil circuit design, the energy consumption per unit block of the extremely cold model has been reduced by 18%. Meanwhile, the IoT module equipped can remotely monitor 32 operating parameters. A customer from Inner Mongolia replaced the worn seals in advance through data analysis, thus avoiding a hydraulic cylinder scrapping accident worth 500,000 yuan.

        Good equipment should be like the fur of a polar bear - both resistant to the cold and light and efficient. General Manager HONGJIA outlined his vision at the annual customer appreciation meeting: "We are developing a hydrogen energy hydraulic drive system. In the future, the ultra-cold models will achieve zero-emission production, making construction sites true producers of clean energy."

        From breaking through physical limits to redefining industry standards, HONGJIA MACHINERY is proving through technological innovation that extreme environments are not the end of production but a new starting point for innovation.
