Our company focuses on the field of engineering machinery accessories, and its main products are pins and bushings for loaders and excavators. With professional production capacity and flexible customization mode, we provide customers with high-quality products and services.

1. Main products

(I) Engineering machinery pins

Widely used in various types of engineering machinery, such as excavators, loaders, bulldozers, cranes, etc., connecting various key components of the equipment, such as booms, dipper arms, buckets, lifting arms, etc., to ensure accurate transmission and stable connection between components.

(II) Engineering machinery bushings

As a key component of connecting parts in engineering machinery, bushings are widely used in various articulated parts, such as the connection between the bucket and dipper arm of the excavator, the connection between the boom and the frame of the loader, etc., to play the role of support, positioning, friction reduction and buffering, protect the key components of the equipment, and improve the overall performance and reliability of the equipment.

2. Customized services

(I) OEM production

We have rich OEM production experience and can provide customers with one-stop OEM services according to the brand needs and quality standards of customers. From product design, mold development, production and manufacturing to quality inspection, packaging and transportation, we strictly operate in accordance with customer requirements and international standards to ensure that we provide customers with high-quality, cost-effective products and help customers build a competitive brand image.

(ii) Production according to drawings

If the customer already has detailed product drawings, our professional technical team can quickly interpret the drawing requirements and develop precise production processes and quality control plans based on the drawings. We use advanced CNC processing equipment and high-precision testing instruments to strictly produce according to the drawing dimensions and technical requirements to ensure that the various indicators of the product are completely consistent with the drawings and meet the customer's personalized customization needs.

(iii) Sample customization

For customers who only have samples but no drawings, we provide professional sample customization services. First, our technicians will conduct a comprehensive analysis and inspection of the samples, including material composition, dimensional accuracy, surface quality, mechanical properties, etc. Then, using advanced reverse engineering technology, the samples are converted into accurate three-dimensional models and production drawings. During the production process, we strictly manufacture in accordance with the quality standards of the samples, and through multiple sample trials and optimizations, we ensure that the final product is completely consistent with the original sample in appearance, size, performance, etc., and even exceeds the quality level of the original sample.

>> Product Raw Material

High carbon chromium bearing steel: 

such as GCr15, has high hardness, strength and wear resistance. After quenching and tempering, it can maintain good dimensional stability and wear resistance in the high-load and high-friction working environment of the excavator bucket, effectively extending the service life of the bushing. The chromium element it contains can enhance the corrosion resistance of the steel, so that the bushing can adapt to various harsh working conditions.

High-strength alloy steel: 

high-strength alloy steel with a variety of alloy elements such as manganese, molybdenum, vanadium, etc., has excellent comprehensive performance. It not only has high strength and hardness, can withstand the huge pressure and stress of the bucket during the excavation process, but also has good toughness and fatigue resistance, and is not prone to failure forms such as cracks and fractures in frequent working cycles.

Raw material preparation

Material inspection: According to the product design requirements, purchase standard steel, such as high carbon chromium bearing steel, high strength alloy steel, etc., check the quality certification documents of the materials, including chemical composition, mechanical properties and other indicators, to ensure the quality of the raw materials.

Cutting: According to the size specifications of the bushing, use cutting equipment, such as flame cutting machine, plasma cutting machine or sawing machine, to cut the steel into suitable blanks. The size of the blank should take into account the subsequent processing allowance.

Heating the blank: Heat the blank to the appropriate forging temperature range. The forging temperature of different steels varies, generally around 1000℃-1200℃, so that the steel has good plasticity

Rough processing: Use lathes, milling machines, drilling machines and other equipment to rough process the forged blanks to process the basic structures such as the inner and outer diameters, length, and oil grooves of the bushing. During rough processing, a certain allowance should be left for fine processing.

Finishing: Use high-precision grinding machines, boring machines and other equipment for finishing, strictly control the inner diameter and outer diameter dimensional tolerances and surface roughness of the bushing, ensure the matching accuracy with the pin shaft, and ensure the accuracy and surface quality of the oil groove, oil hole and other positions.

Heat treatment

Quenching: According to the material and performance requirements of the bushing, select a suitable quenching process, heat the machined bushing to above the critical temperature, keep it warm for a certain period of time and then cool it rapidly, so that the bushing obtains martensite and other strengthening structures to improve hardness and strength.

Tempering: The quenched bushing is tempered to eliminate quenching stress, stabilize the structure and size, and improve toughness. According to the product performance requirements, low-temperature tempering, medium-temperature tempering or high-temperature tempering can be used.

Surface treatment: In order to improve the wear resistance and corrosion resistance of the bushing, surface treatment such as hard chrome plating and chemical nickel plating can be performed to form a hard and corrosion-resistant protective film on the surface of the bushing.

Quality inspection

Dimensional accuracy inspection: Use precision measuring tools such as calipers, micrometers, and three-dimensional coordinate measuring machines to ensure that the dimensional deviation is within the tolerance range required by the design.

Surface quality inspection: Check whether there are cracks, scratches, sand holes and other defects on the surface of the bushing by visual observation, optical microscope or electron microscope, and measure whether the surface roughness meets the standard.

Hardness inspection: Use a hardness tester to test the hardness of different parts of the bushing to ensure that the bushing has sufficient hardness and wear resistance.

Assembly test: Take a certain number of bushings for assembly test, assemble the bushing with the pin, and check whether the fitting clearance is appropriate, whether the rotation is flexible, and whether there is any jamming.
