In construction machinery operations, breakers frequently endure relatively high impact and complex stresses. Ordinary forgings are prone to fatigue cracking, deformation, and failure, directly affecting construction efficiency and equipment lifespan. Jianing Forging's breaker forgings use the free forging process, strictly controlling everything from raw materials to finished products, improving fatigue strength and structural stability, making every crushing operation more reliable and durable
In construction machinery operations, breakers frequently endure relatively high impact and complex stresses. Ordinary forgings are prone to fatigue cracking, deformation, and failure, directly affecting construction efficiency and equipment lifespan. Jianing Forging's breaker forgings use the free forging process, strictly controlling everything from raw materials to finished products, improving fatigue strength and structural stability, making every crushing operation more reliable and durable.
The breaker forgings produced by Jianing Forging are free-forging parts specially designed for construction machinery, suitable for key parts such as various breaker bits, cylinder blocks, and pistons. Relying on open-die forging technology, the internal structure of the forgings is dense and the streamlines are reasonably distributed, possessing excellent comprehensive mechanical properties. Products can be customized according to customer equipment models and working condition requirements to meet the practical needs of different tonnages and working environments.
Relatively high strength materials: Selected high-quality alloy steel, which has undergone chemical composition and mechanical performance retesting, helps improve the quality of raw materials.
Open-die forging process: Through multi-directional forging, internal defects are eliminated, grain refinement is achieved, and the overall toughness of the forging is improved.
Relatively accurate allowance control: Reasonable machining allowance is reserved according to drawings, reducing subsequent machining time and consumables.
Full-process inspection: Includes ultrasonic flaw detection, hardness testing, and dimensional calibration, helping every product meet standards.
Optional surface treatments: post-treatment such as quenching and tempering, normalizing, and anti-rust spraying can be provided to enhance surface wear and corrosion resistance.
Breaker forgings are customized products, with prices determined based on specific specifications, material requirements, machining precision, and order quantity. Customers can provide drawings or samples for customized quotations, and Jianing Forging will offer competitive solutions.
From technical communication to batch delivery, dedicated engineers handle the entire process to help accurately understand requirements.
We strictly implement the ISO quality management system and provide material certificates and test reports.
Before the finished product leaves the factory, dimensions and flaw detection are re-inspected, with zero outflows of nonconforming products.
If quality issues arise during use, respond within 24 hours and provide a solution.
