‌Quality Control Meeting Minutes: Strengthening Production Standards and Delivery Commitments for Recrystallized Silicon Carbide Products

‌Date:‌ 2025.03.17

‌Attendees:‌ Production Managers, Quality Assurance Team, Supply Chain Coordinators, R&D Specialists, Sales Representatives

‌Objective:‌
To reinforce stringent quality control measures, optimize production scheduling, and ensure on-time delivery of high-grade recrystallized silicon carbide roducts to meet evolving customer expectations.

‌1. Emphasizing Zero-Compromise Quality Standards‌
The meeting commenced with a unanimous resolution to prioritize silicon carbide product quality as the cornerstone of operational excellence. Key decisions included:

• Raw Material Screening:‌ Implementing advanced spectroscopy and X-ray diffraction (XRD) testing for all incoming silicon carbide powders to verify purity (>99.5%) and particle size distribution compliance. Suppliers failing three consecutive batches will undergo requalification audits.

• ‌Process Parameter Optimization:‌ The R&D team will recalibrate sintering temperatures (1,800–2,200°C range) and pressure controls within 72 hours to minimize micropore formation, ensuring silicon carbide products achieve ≥98% theoretical density.

• Non-Destructive Testing (NDT) Protocols:‌ Introducing ultrasonic testing and industrial CT scanning for 100% of finished silicon carbide products to detect subsurface flaws, with defective units isolated for root-cause analysis.

A monthly "Quality Benchmarking Forum" will be established to review ISO 9001:2015 compliance metrics and address non-conformities within 24 hours.

‌2. Intelligent Production Scheduling for Demand-Driven Output‌

To resolve bottlenecks in high-volume orders, the production team proposed:

• ‌Dynamic Capacity Modeling:‌ Integrating ERP system data with real-time furnace availability to allocate 70% capacity to guaranteed orders and 30% to flexible batch production, reducing idle kiln time by 18%.

• ‌Cross-Shift Coordination:‌ Implementing overlapping 10-hour shifts during peak demand (Q3–Q4) to maintain 24/5 operational continuity, supported by predictive maintenance algorithms to minimize unplanned downtime.

• ‌Buffer Stock Strategy:‌ Maintaining a 15-day safety stock of semi-finished silicon carbide blanks for urgent orders, reducing lead times from 28 to 12 days for priority clients.

Sales and production teams will jointly finalize a rolling 90-day forecast by the 25th of each month, adjusting for raw material lead times (45–60 days for premium graphite molds).

‌3. Customer-Centric Delivery Assurance Framework‌
To uphold contractual obligations and brand reputation, the supply chain group outlined:

• ‌Logistics Partnerships:‌ Qualifying two additional freight forwarders specializing in fragile ceramic shipments, with GPS-tracked climate-controlled containers mandatory for overseas orders.

• ‌Proactive Communication Protocol:‌ Automated SMS/email alerts for customers at each milestone (e.g., kiln loading, post-sintering inspection), supplemented by weekly video conferences for projects exceeding 50 metric tons.

• ‌Penalty Mitigation Plan:‌ Allocating 0.5% of quarterly revenue to a "Customer Satisfaction Fund" for expedited shipping or discounted future orders in case of delays attributable to internal processes.
