Manufacturing Process
The product is manufactured from high-strength steel through forging, which provides continuous metal flow lines and superior load-bearing and fatigue resistance compared to cast parts. The surface receives a hot-dip galvanized finish with uniform coating and strong adhesion for long-term outdoor service. The ball end is precision-machined with tight control over profile and dimensional tolerances, while the U-type clevis fork's inner width and pin hole positioning are simultaneously controlled for smooth installation with matching hardware. Production strictly follows national electric power industry standards.
Quality Control
Hebei Tongchuang Power Fittings Co., Ltd.'s forging production line is equipped with double-disc friction presses and open-type presses capable of hot forging the integrated ball-and-U component, ensuring dense metal structure and freedom from internal defects. Subsequent processing uses horizontal lathes and universal tool milling machines for precision finishing of the ball face and fork. Quality control includes full dimensional inspection and mechanical property sampling beyond routine visual checks, with three key parameters monitored: ball head diameter, U-type opening size, and concentricity. The company is a nationally recognized high-tech enterprise with over ten patent authorizations.
Procurement and Support
Given that Q-U and QS Series products are primarily used in critical transition points, dimensional fit is essential. Customers can provide installation drawings or site parameters for technical review and dimensional adjustment. The standard MOQ is 8,000 pieces, with negotiation possible for larger first orders. Sample trials can be completed within 4 weeks, including mold development, trial production, and dimensional verification. Export packaging uses anti-rust film with carton boxes, and heavy items are packed in additional fumigated wooden crates. Delivery is 7 working days for stock items, with custom orders taking approximately 2 weeks. All products come with a one-year global warranty and dedicated after-sales support.
