KDET provides professional mold flow analysis and Moldflow simulation services that identify and resolve potential molding defects before a single chip of steel is cut. Using industry-leading Autodesk Moldflow software, our engineering team performs comprehensive filling, packing, cooling, and warpage analyses to optimize gate location, runner design, cooling circuit layout, and processing parameters. Since 2007, our mold flow analysis services have helped clients eliminate costly trial-and-error iterations, reducing mold development time by 20-30% and eliminating common defects including weld lines, air traps, sink marks, and excessive warpage.

KDET delivers world-class mold flow analysis solutions engineered to meet the demanding requirements of global OEM manufacturers. With 18 years of industry experience, ISO 9001:2015 and IATF 16949 certifications, and a fully integrated manufacturing facility, we provide comprehensive solutions from initial engineering consultation through tooling, production, quality assurance, and international logistics. Our structured project management methodology ensures transparent milestones, clear communication, and documented quality verification at every stage.

• Complete Filling Analysis: We simulate the complete mold filling process including melt front advancement, pressure distribution, shear rate analysis, and temperature profiles to identify potential short shots, hesitation, and unbalanced filling before mold manufacturing begins.
• Gate Location Optimization: Computational analysis of multiple gate location scenarios identifies the optimal gate position that minimizes injection pressure, eliminates weld lines in critical areas, and ensures balanced cavity filling for multi-cavity configurations.
• Warpage Prediction & Compensation: Our warpage analysis predicts post-molding dimensional deviation due to differential shrinkage, orientation effects, and cooling rate variation. We provide reverse-warpage compensation data that can be applied to the mold design for net-shape parts.
• Cooling Circuit Optimization: Transient cooling analysis evaluates cooling channel layout, diameter, and flow rate to achieve uniform mold surface temperature within ±3°C. Optimized cooling reduces cycle time by 15-25% while improving part dimensional stability.
• Material-Specific Database: We maintain an extensive material database with characterized rheological, thermal, and mechanical properties for over 2,000 commercial plastic grades, ensuring simulation accuracy that matches real-world molding behavior.
• Detailed Analysis Report: Every mold flow study includes a comprehensive report with fill time animations, pressure and temperature distribution plots, weld line and air trap locations, clamping force estimation, and specific recommendations for mold design and processing parameters.

• New Product Development: Validate moldability of new part designs before committing to tooling investment. Identify and resolve gate location, wall thickness, and draft angle issues during the design phase when changes are inexpensive.
• Complex Geometry Parts: Components with thin walls, long flow paths, multiple gates, or complex geometries where filling behavior is difficult to predict from experience alone.
• High-Cavitation Molds: 16-96 cavity configurations where unbalanced filling between cavities can cause inconsistent part quality, excessive clamp force requirements, and premature mold wear.
• Precision & Optical Components: Parts with tight warpage tolerances where differential shrinkage prediction and reverse-warpage compensation are essential for achieving dimensional specifications.
• Material Change Validation: When switching from one material grade to another, mold flow analysis predicts how the new material will behave in the existing mold and identifies any required process or design adjustments.
