HPDC Quality Recovery Consultant .Strategic Quality Recovery for High Pressure Die Casting Operations. When critical quality issues threaten customer confidence, production continuity, or commercial stability, decisive expertise is essential.
Dr Sylvia Bih Neba provides specialist advisory and hands-on intervention for HPDC automotive suppliers navigating major customer escalations, containment measures, and systemic quality breakdowns. Our mandate is clear: stabilise operations rapidly, restore credibility, and embed sustainable corrective structures that safeguard long-term performance.

With more than two decades of direct HPDC manufacturing and customer-facing leadership experience, we operate at the intersection of plant-floor execution and OEM expectation.

Immediate Stabilisation. Structured Resolution. Enduring Control.From porosity and dimensional instability to complex die casting defects, we deploy a disciplined, OEM-aligned methodology that ensures:

 

  • Rapid containment of risk
  • Protection of customer production lines
  • Thorough root cause validation
  • Implementation of robust corrective and preventive actions
  • Reinforcement of process governance

Support can be delivered on-site within your facility or remotely, depending on urgency, geography, and operational requirements — ensuring agility without compromising depth of intervention.

 

We do offer theoretical consultation and deliver operational recovery.

 

Executive-Level Expertise in HPDC Quality Management

Dr Sylvia Bih Neba brings over 20 years of progressive leadership within High Pressure Die Casting environments, including senior roles as:

  • Senior Quality Technician
  • Quality Manager
  • Project Manager
  • Customer Quality Representative

This cross-functional trajectory provides a rare and valuable capability: translating complex manufacturing realities into structured, customer-ready quality assurance aligned with OEM standards.

Deep Technical Focus

Our expertise concentrates specifically on critical HPDC defect mechanisms and systemic vulnerabilities, including:

  • Gas and shrinkage porosity
  • Dimensional instability and variation
  • Die casting process defects
  • Tooling performance and thermal imbalance
  • Repeat non-conformance and escalation patterns

In addition to plant-level intervention, we conduct independent audits of raw material producers and upstream suppliers, ensuring alloy integrity, process consistency, and compliance with agreed technical specifications.

We also monitor and analyse production trends and performance data, identifying emerging risk patterns before they escalate into customer-impacting issues.

Each engagement is grounded in disciplined analysis, validated data, and measurable outcomes.

Our Commitment

Quality recovery is not containment alone. It is the restoration of operational credibility.We operate with precision, discretion, and strategic clarity — ensuring that immediate crises become catalysts for long-term structural strengthening.

Root cause analysis

Specialist Advisory & Intervention Services

1. Rapid Containment & Operational Stabilisation
Immediate response to critical quality alerts and escalation scenarios.

 

• On-site or remote emergency intervention

• Structured containment planning

• Risk and exposure assessment

• Customer-facing communication support

• Escalation mitigation

 

Our priority: protect the customer while regaining internal process control.

2. Root Cause Determination & OEM-Aligned 8D Leadership

Comprehensive investigation conducted under recognised, structured methodologies aligned with OEM expectations.

Tools and methodologies include:

• 5 Why analysis

• Fishbone (Ishikawa) analysis

• Pareto prioritisation

• Primary production process audits

• Defect mechanism mapping

• Data validation and statistical confirmation

 

Root cause findings are substantiated, verified, and aligned to formal 8D reporting standards.

3. Corrective & Preventive Action Deployment

Design and execution of sustainable corrective frameworks that eliminate recurrence at source.

• Process parameter optimisation

• Tooling and thermal balance evaluation

• Control plan and PFMEA enhancement

• Error-proofing strategy

• Verification and effectiveness audits

We remain engaged through validation to ensure durability of implementation.

 

4. Supplier & Raw Material Auditing

Upstream instability frequently drives downstream non-conformance. We therefore extend our scope beyond internal operations to include:

• Audits of raw material producers

• Alloy composition and traceability verification

• Supplier process capability assessment

• Risk evaluation within the supply chain

• Alignment with automotive compliance standards

This proactive oversight strengthens supply chain integrity and reduces defect propagation risk.

5. Production Trend Monitoring & Risk Anticipation

Sustainable quality performance requires forward-looking oversight.

We analyse:

• PPM evolution

• Scrap and rework patterns

• Process capability indices

• Thermal and tooling performance trends

• Repeat defect indicators

 

This structured monitoring allows early intervention, reducing exposure before escalation occurs.

6. Quality System Reinforcement

Beyond incident resolution, we strengthen organisational resilience.

• Production process audits

• Process stability evaluation

• Governance and control system enhancement

• Preventive risk identification

• Continuous improvement alignment

 

The objective is not recovery alone — it is institutional capability elevation.
