Mold Quality – Hanoi Mould Precision and Reliability

At Hanoi Mould Technology Co., Ltd, mold quality is the foundation of our success and reputation. Every injection mold we design and manufacture follows international ISO 9001:2015 quality standards, ensuring precision, consistency, and durability for global customers in automotive, electronics, medical, and household industries.

1. Mold Quality Assurance Process

The mold quality control system at Hanoi Mould begins at the earliest design stage. We perform DFM (Design for Manufacturability) analysis, material selection, and feasibility evaluation before any machining process starts.
Each design is reviewed by senior engineers to ensure optimal cooling, injection flow, and ejection systems that deliver consistent plastic parts with perfect finish and dimensional accuracy.

2. Precision Machining and Inspection

During production, our mold quality is guaranteed through high-precision CNC machining, wire-cut EDM, and digital measuring systems. All critical dimensions are checked using CMM (Coordinate Measuring Machine) and projector inspection to maintain tolerances within ±0.005 mm.
Every core, cavity, and component is polished, hardened, and verified to meet international standards before assembly.

3. Testing and Validation

Each mold undergoes complete trial runs (T1, T2, and T3) to validate:

* Injection balance and filling

* Cooling efficiency

* Dimensional accuracy of molded parts

* Tool durability and cycle performance

Our engineers record test data and provide detailed inspection reports before shipment. This documentation ensures full traceability and long-term reliability of every mold delivered.

4. Global Quality Commitment

With over 20 years of experience and exports to Germany, the USA, Japan, and the EU, Hanoi Mould Technology is trusted worldwide for its commitment to excellence and reliable mold quality.
We continue to improve through advanced training, automation, and strict quality monitoring to achieve world-class performance.
