David, our valued client from the UK, has stood with YZCONN for nearly a decade. Looking back, that first collaboration in the early 2010s wasn't just a business deal—it was the start of a partnership built on solving real challenges and delivering on promises.
Our first step was 3D modeling using CAD software, tailored to David's specific requirements. We focused on four key optimizations to avoid common pitfalls: mold parting surfaces to minimize flash, runner/gate design for uniform alloy filling, ejector pin layout to prevent deformation during demolding, and venting grooves to eliminate air pockets and reduce porosity.
Mold Preheating: We heated the mold to 150-200℃ using built-in heating rods and oil circulation systems, preventing cold shuts and shrinkage caused by rapid cooling of the alloy.
Clamping and Injection: The die-casting machine's clamping force was adjusted to 50-100T (ideal for David's DB9 housing), ensuring a tight seal. Molten zinc alloy was injected into the cavity at 10-50m/s, filling it in just 0.05-0.2 seconds to avoid material shortages in thin-walled areas.
Pressure Holding and Cooling: A pressure of 10-30MPa was maintained for 2-5 seconds to compensate for shrinkage, followed by water cooling through internal channels. Cooling time was set to 0.5-2 minutes based on wall thickness—no detail was left to chance.
Demolding and Trimming: Ejector pins pushed the formed housing out after cooling, and robotic arms retrieved the blank. We then performed precision machining to remove gates, runners, flash, and burrs, ensuring perfect fit for assembly.
When David received the prototypes, his team conducted rigorous testing—and the results spoke for themselves. We immediately ramped up mass production and delivered the entire order right on his tight deadline. That on-time delivery wasn't just a relief for David; it was the moment he knew he'd found a long-term partner.
Ten years later, that initial project has evolved into a decades-long collaboration. David has gone on to launch countless successful projects, and YZCONN has been right there with him, adapting to new requirements and maintaining the same precision and reliability that won his trust years ago.
