Product Description:
This product is manufactured from ZL102 aluminum alloy via high-pressure die casting. ZL102 offers excellent corrosion resistance and cost efficiency, making it an ideal choice for outdoor structural connectors. Featuring a tapered transition design, one end is fitted with a circular through-hole, while the opposite end adopts a square/rectangular interface (with dual side holes). It is specifically engineered for the secure connection or angled support of tubular sections with different profiles, such as round and square tubes.

Manufacturing Process
This product is manufactured through High-Pressure Die Casting of ZL102 aluminum alloy, forming a single integrated piece. The high silicon content of ZL102 provides excellent fluidity, enabling the molten metal to fully fill the mold cavity and accurately reproduce complex structural details such as the tapered transition, round/square interfaces, and dual side holes. The resulting casting features a dense structure and good air tightness.
After casting, gates and risers are trimmed off to remove excess material. The parts then undergo a dual-stage finishing process: vibratory tumbling removes general parting-line burrs, while skilled operators perform precision deburring on hole edges and critical mating surfaces. All sharp edges and flash are thoroughly eliminated to ensure smooth assembly fit and safe handling.
Finished products are subject to random dimensional inspection to verify compliance with assembly requirements. Each unit is cleaned, securely packaged, and shipped together with the Material Certificate and Dimensional Inspection Report.
