HMB hydraulic breakers have always been known for their “excellent quality and durability”. Many customers chose other brands because of the price, but the cheap brands of hydraulic breakers frequently had problems, and in the end most customers chose HMB again. HMB hydraulic breakers did not disappoint customers!
HMB is one of the leading manufacturers of excavator attachments in China. All products are strictly quality controlled from raw material selection, processing to delivery. Through continuous innovation and improvement, the company has successively obtained ISO 9001 quality system certification, CE certification and technical patents. Our products are sold well at home and abroad, and we have established long-term partnerships.
This time, let the editor show you Why can HMB hydraulic breaker stand out in the industry?
High-quality raw materials
● As a high-impact device, a component that is often overlooked is the through bolt
The through bolt diameter of HMB is 21mm, for the sake of higher strength. A larger bolt diameter can improve the tensile strength, especially under heavy impact conditions, with higher load-bearing capacity, suitable for high-intensity operations (such as mining and hard rock crushing), while the through bolt diameter of peers is 20mm.
● Core components such as pistons, cylinders, and chisel must be made of high-strength alloy steel (such as 42CrMo) and undergo special heat treatment (such as carburizing and quenching) to withstand high-frequency impact and wear.
● Oil seal: HMB seals use YBS from South Korea, which is resistant to high pressure and oil corrosion, and will not deform after long-term use. Peers use ordinary oil seals.
Precision machining process
● Heat treatment:
Our own Heat Treatment system, to make sure 32 hours heat treatment time to make sure the carburized layer be between 1.8-2mm, the hardness be 58-62 degree.
● Tolerance control
The machining accuracy of matching parts (such as valve core, piston) must reach micron level to ensure sealing and power transmission efficiency.
● Surface treatment:
Chrome plating, nitriding and other processes can reduce friction coefficient and extend life (for example, the thickness of piston rod coating must be ≥0.05mm).
Strict testing standards
Each hydraulic breaker of HMB will be tested before leaving the factory to ensure that it meets international standards.
R&D and certification investment
Brand manufacturers need to invest a lot of money to continuously improve the quality of hydraulic breakers and pass international certifications such as ISO and CE.

Potential risks caused by low-priced hydraulic breakers
1.Short equipment life
Low-priced products usually use inferior steel or simplified heat treatment processes. The core components (piston, cylinder, drill rod) are easy to wear and break, and the service life may be only 1/3-1/2 of high-end products.
2.Maintenance cost surge
Seals are prone to failure, resulting in hydraulic oil contamination, which in turn damages the hydraulic system of the excavator. The cost of a single repair can reach 30%-50% of the equipment price.
The cumulative cost of frequently replacing wearing parts (such as accumulators and oil seals) may exceed the initial price difference.
3.Low work efficiency
The impact force decays quickly (the impact force decreases by 20%-30% after 200 hours of use), the demolition efficiency is reduced, and the extended construction period leads to increased labor and equipment rental costs.
4.Safety hazards
Shell welding defects may burst under high pressure, and splashing fragments may cause personal injury, and the company faces the risk of compensation for safety accidents.
5.Indirect economic losses
Fine penalties for breach of contract due to downtime (e.g. daily penalty for municipal projects can reach 0.5%-1% of the contract amount)
