High-precision CNC milling with micro-grain tooling achieves tolerances as tight as ±0.01mm in critical areas. Wire EDM is used for complex internal geometries and sharp corners that are impossible to mill. Grinding operations refine surfaces and ensure flatness. All processes follow detailed CMM inspection reports to verify conformity with 3D model specifications.
First-article inspections validate all critical dimensions before full production. Coordinate Measuring Machines (CMM) check key features against CAD models. Statistical Process Control (SPC) tracks dimensional trends during production runs. Any deviation triggers immediate corrective action. This systematic approach ensures every mold meets the highest precision standards required for LSR applications.
Mold flow analysis predicts how LSR will fill complex cavities, identifying potential problem areas before physical cutting begins. Warpage simulation helps optimize cooling channel layouts and ejection pin positions. These digital tools reduce trial-and-error iterations, saving time and material costs. They're essential for achieving first-time-right results in high-precision mold manufacturing.
Complex features like undercuts are addressed with side-actions, lifters, or collapsible cores. Advanced CAM programming generates toolpaths that maintain surface integrity while achieving intricate shapes. Specialized fixtures hold workpieces securely during multi-axis machining. Skilled craftsmen combine technology with experience to solve unique geometric challenges in LSR mold design.
