Upgraded Precision Casting & CNC Machining Capacity, Our Gearbox Housings Bulk Delivered for Overseas Orders

Recently, a batch of precision-machined gearbox housings and reducer housings have passed complete quality inspection and are ready for bulk shipment to overseas markets, fully demonstrating our outstanding strength in precision casting and high-precision CNC machining.

All our transmission housing castings are made of high-quality HT250 grey cast iron. Adopting mature precision casting technology and professional annealing stress relief treatment, our products eliminate internal stress thoroughly and avoid common casting defects such as pores and sand inclusions. Featuring high strength, high rigidity and excellent vibration damping performance, the castings are perfectly suitable for heavy-duty and complex working conditions of mining machinery, construction machinery, agricultural machinery and industrial transmission equipment.

Equipped with multiple high-end large-scale CNC machining centers, our factory independently completes full-process precision processing including boring, precision milling, drilling and chamfering. We strictly control geometric tolerance and assembly accuracy to ensure every finished product has accurate dimensions, stable sealing performance and high assembly adaptability, meeting the supporting requirements of high-end mechanical equipment.

We have established a standardized full-process quality inspection system, implementing layer-by-layer inspection and verification from raw material incoming, casting and machining to finished product delivery. All products support comprehensive third-party authoritative inspections, including ultrasonic flaw detection, mechanical performance testing, dimensional accuracy verification and tightness testing, with official test reports provided. Our products fully comply with global industrial quality standards.

In addition, our professional technical team can optimize product structure and performance according to customers’ equipment working conditions and custom drawings to improve product wear resistance and service life. With mature production technology, reliable quality and strong mass production capacity, our products are sold well all over the world. We continuously provide high-quality and cost-effective customized casting housing solutions for global clients. In the future, we will keep upgrading production technology and equipment, strictly control product quality, and further explore the global industrial accessories market.
