ABOUT JOINCAST

Partnership-Focused Die Casting Since 1987

JoinCast's 170-person professional team performing manual quality inspection and assembly within a vertically integrated aluminum die casting facility in Taiwan.

JoinCast was founded in 1987 with a commitment to precision aluminum die casting for international markets. Over three decades, we evolved from coordinating external suppliers to building complete in-house capabilities, investing in mold engineering, CNC automation, and surface treatment systems that eliminate the quality inconsistencies and delays our customers experienced with fragmented supply chains.

We continue investing in automation to strengthen manufacturing efficiency while maintaining the flexibility international brands require. Our recent additions include automated loading systems for CNC operations and fully automated surface treatment lines. This commitment to technological advancement ensures we remain competitive while delivering the precision and consistency our customers have relied on for decades.
