Driving Engineering Innovation through Gigacasting, Vacuum-Assisted HPDC, Rheocasting, and Low-Carbon Alloy Science
Traditional die casting often suffers from trapped gas porosity, rendering parts non-heat-treatable. Our engineering roadmap integrates sub-50 mbar high-vacuum assisted extraction during metal injection. This enables gas porosity mitigation down to less than 0.5%, allowing full T6 heat treatment to yield tensile strengths exceeding 320 MPa.
By controlling metal slurry solidification between liquid and solid phases, Rheocasting reduces turbulent flow and shrinkage during cavity fill. This process yields near-zero porosity structural parts with enhanced elongation (up to 12%), ideal for crash-relevant automotive EV battery trays and suspension arms.
Deploying Industry 4.0 sensors into mold cavities enables real-time temperature gradient monitoring. Automated cooling jet adjustments eliminate hot spots, optimize cycle times by 18%, and extend die life from 100,000 shots up to 150,000+ shots through minimized thermal fatigue.
Aligning with global ESG mandates, XinYe is transitioning towards low-carbon aluminum ingots containing over 80% recycled content without compromising chemical purity or yield stress. This reduces Scope 3 carbon footprints for automotive and consumer electronics OEMs by up to 65%.

Design for Manufacturability Guidelines to Reduce Tooling Cycles, Lower Costs, and Eliminate Quality Risks
Proper draft angles ensure smooth component ejection from die cavities without dragging or distortion. We recommend a minimum draft angle of 1.0° to 2.0° for internal walls and 0.5° to 1.0° for external surfaces based on alloy selection.
Non-uniform wall thickness causes uneven cooling rates, leading to internal porosity, sink marks, and residual stress. Our engineering team conducts DFM reviews to enforce wall thickness transitions within 2.0mm - 4.5mm.
Sharp internal corners create stress concentration points and accelerate mold thermal cracking. Applying generous radii (R ≥ 1.5mm) enhances melt flow fluidity, reduces air entrapment, and triples tooling lifespan.
For OEM global enterprise clients, we deliver full Production Part Approval Process (PPAP) Level 3 packages including Process Flow Diagrams, PFMEA, Dimensional Inspection Reports, Material Certifications, and Gauge R&R studies.
