Zhijing Precision Machinery (Shanghai) Co., Ltd. Solves Packaging Leakage for MSD China, Enhancing Design Beyond Original Supplier

Client: MSD China (Merck Sharp & Dohme)

Challenge: Persistent Packaging Leakage in Critical Pharmaceutical Products

Solution: Customized Redesign & Precision Manufacturing by Zhijing Precision Machinery

Result: Zero Leakage, Improved Efficiency, and Long-Term Partnership

Background

MSD China, a leading global pharmaceutical company, faced recurring packaging leakage issues with a critical medical product. The original packaging machine, supplied by another manufacturer, failed to ensure a complete seal, risking product integrity and regulatory compliance. After multiple unsuccessful attempts to resolve the issue with the initial supplier, MSD China turned to Zhijing Precision Machinery (Shanghai) Co., Ltd. for a reliable solution.

The Challenge

• Leakage in Seals: The existing packaging machine’s sealing mechanism had inconsistent performance, leading to product spoilage and potential compliance risks.

• Tight Tolerances Required: Pharmaceutical packaging demands ultra-precise alignment and pressure control to maintain sterility and prevent contamination.

• Urgent Timeline: MSD needed a rapid yet sustainable fix to avoid production delays.

Zhijing’s Solution

Zhijing’s engineering team conducted a thorough root-cause analysis and identified key flaws in the original design:

1. Insufficient Pressure Control – The sealing mechanism lacked dynamic adjustment, causing uneven pressure distribution.

2. Material Wear & Tear – Critical components degraded quickly under high-frequency operation.

3. Poor Alignment Precision – Minor misalignments led to weak seals.

Zhijing’s Customized Improvements:

• Redesigned Sealing Jaws: Incorporated high-wear-resistant materials and optimized pressure distribution for consistent performance.

• Enhanced Sensor Integration: Added real-time monitoring to detect and correct misalignments instantly.

• Precision Machined Components: Upgraded critical parts with tighter tolerances to eliminate variability.

Results & Client Feedback

• Zero Leakage: After implementation, MSD China reported no further leakage incidents, ensuring product safety and compliance.

• Increased Efficiency: The modified machine operated 20% faster with reduced downtime.

• Cost Savings: Eliminated waste from defective packaging, saving thousands in annual losses.

"Zhijing’s expertise in precision machinery was evident from the start. They not only fixed the leakage issue but improved the entire system beyond our expectations. Their proactive approach and technical excellence make them a trusted partner."
