C44300 Brass Bronze Bushings And Bearings H62-1

The superior quality of our C44300 Brass Bronze Bushings and Bearings H62-1 stems from Fengquan's 30 years of dedicated craftsmanship in copper alloy casting and rigorous quality control throughout the entire process. From raw material selection to finished product delivery, every step is meticulously executed to ensure stable and reliable product quality.

Advanced Casting Technology

We utilize electric furnace melting and precision casting technology, with 25 electric furnaces and 50 casting machines, boasting an annual production capacity of 46,000 tons. Casting sizes range from 15mm to 2000mm, meeting the production needs of various specifications. During smelting, strict control of element ratios ensures uniform alloy composition. The casting process employs precision temperature control and uniform casting technology to reduce defects and guarantee a dense microstructure in the castings, laying the foundation for machining.

Precision Machining: Two specialized machining workshops are equipped with 30 high-precision machining machines, possessing full-process machining capabilities. Products can be rough, fine, and precision machined, achieving dimensional accuracy down to 0.5mm per side. Non-standard parts can be customized according to customer drawings. CNC programming and real-time accuracy testing are used during machining, with technical personnel monitoring the entire process to ensure accurate product quality.

Full-Process Quality Control System

A full-process quality control system is established from raw materials to finished products. Equipped with five professional testing devices, including a spectrometer and flaw detector, it achieves four-fold quality control: incoming material inspection → in-process sampling inspection → finished product full inspection → outgoing re-inspection. Spectroscopic analysis detects alloy element composition, and flaw detection detects internal defects in castings. Strict testing of key indicators such as dimensional accuracy, hardness, and corrosion resistance ensures that no unqualified products leave the factory.

Rapid Delivery Capability

Leveraging a certified production capacity of 40,000 tons, large-scale production lines, and ample raw material reserves, the company possesses rapid delivery capabilities, efficiently responding to urgent order demands. Whether it's a standard model bulk order or a non-standard customized small-batch order, production can be quickly scheduled, efficiently manufactured, and delivered on time, shortening the delivery cycle.
