FOUR-STAGE ENGINEERING STORYTELLING

4-Stage Engineering Story & Production Verification

From complex 3D CAD analysis to micron-level 5-axis machining and high-speed production validation.

01

01. Engineering Challenges & Stringent Specs

Ultra-thin walls, deep cavity warpage control, and aesthetic parting lines.
家电内胆结构深达 380mm，壁厚仅 0.8~1.2mm，极易产生充填不足、飞边与内应力开裂；日本客户对尺寸稳定性和长期耐低温冲击有极其严苛的要求。
02

02. XH Engineering Solution & DFM Simulation

Sequential valve-gate hot runners and conformal cooling channel optimization.
星火模具工程师团队联合客户进行 3 轮 DFM 结构改型，采用平衡式针阀热流道结合微排气镶块系统，杜绝困气焦斑。
03

03. Precision Tooling & Machining Breakthrough

Makino high-speed CNC milling, Sodick linear EDM, and Swiss wire-cut interchangeable inserts.
高精度电火花镜面加工，型腔表面粗糙度达到 Ra 0.10μm；采用德国蔡司与海克斯康三坐标全尺寸复测。
