1. Ningbo Hansheng Machinery Parts Co., Ltd. provides a variety of engineering machinery casting products, mainly covering the following categories:
(1) Engine castings
As the core component of engineering machinery, the engine has extremely high requirements for the precision and strength of the castings. The engine castings produced by Ningbo Hansheng Machinery Parts Co., Ltd. include cylinder blocks, cylinder heads, flywheel housings, etc. These castings are made of high-strength cast iron or cast steel materials and processed by precision casting technology. They have good corrosion resistance, high temperature resistance, and wear resistance, and can still maintain stability under long-term high-load operation.
(2) Hydraulic system castings
The hydraulic system is an indispensable part of modern engineering machinery, involving multiple components such as hydraulic pumps, hydraulic motors, and valves. The hydraulic system castings of Ningbo Hansheng Machinery Parts Co., Ltd. are made of high-quality cast steel or cast iron materials, with excellent wear resistance and fatigue resistance, ensuring the long-term stability of the hydraulic system in harsh environments.
(3) Transmission system castings
The components in the transmission system need to withstand large mechanical loads, so the strength requirements of their castings are relatively high. The transmission system castings produced by Ningbo Hansheng Machinery Parts Co., Ltd. include gearboxes, bearing seats, gearbox housings, etc., all of which are made of high-strength cast steel or alloy cast iron. After precision casting and post-processing, they have good mechanical strength and wear resistance, which can effectively extend the service life of the equipment.
(4) Structural castings
Including large castings such as racks, brackets, suspension arms, etc., these castings need to have sufficient load-bearing capacity and impact resistance. The structural castings produced by Ningbo Hansheng Machinery Parts Co., Ltd. can withstand the mechanical stress under various complex working conditions and ensure the normal operation of engineering machinery in harsh environments.
2. Casting process and technical advantages
In the production process of engineering machinery castings, Ningbo Hansheng Machinery Parts Co., Ltd. adopts advanced casting processes, including sand casting, metal mold casting, precision casting, heat treatment and surface treatment, etc. At the same time, it also introduces internationally leading casting equipment, such as CNC casting lines, induction furnaces, high-precision CNC machining centers, etc., to ensure the high precision and high quality of castings. The company also conducts strict quality inspections on castings, including X-ray inspection, ultrasonic inspection, magnetic particle inspection, etc., to ensure that each product meets strict quality standards.
3. Product performance and technical parameters
Material range: high-strength cast iron (such as HT250, HT300), alloy steel, wear-resistant cast steel (such as Mn13).
Weight range: 1 kg to 500 kg, larger specifications can be customized according to customer needs.
Strength performance: tensile strength up to 500-600MPa, elongation ≥5%.
Wear resistance: adapt to harsh working environment, support high-frequency and long-term mechanical operations.
4. Application areas
Engineering machinery: core component castings such as excavators, loaders, bulldozers
Mining equipment: key castings for ore crushers and screening equipment
Agricultural machinery: core component castings such as tractors and seeders
Logistics equipment: transmission and structural parts such as forklifts and cranes
5. Customer service and quality assurance
Ningbo Hansheng Machinery Parts Co., Ltd. always adheres to the concept of "customer first", not only providing high-quality casting products, but also providing customers with complete technical support and after-sales service. From product design, casting production to later heat treatment processing, Ningbo Hansheng Machinery Parts Co., Ltd. maintains close communication with customers to ensure that the products can meet the needs of different customers.
