When it comes to manufacturing plastic parts for high-performance applications, precision isn’t optional—it’s essential. At Dongxinda Mould Technology Co., Ltd., we specialize in crafting custom injection molds that deliver dimensional stability, tight tolerances, and superior part consistency for every shot.

Why Precision Matters in Mold Manufacturing

Industries such as automotive, medical, and electronics demand components with minimal variation. Even a fraction of a millimeter can lead to performance failure or costly rework. That’s why Dongxinda focuses on:

Tight tolerance machining using high-precision CNC equipment
Strict steel selection for dimensional reliability
Mold flow analysis to predict and prevent warping or shrinkage

Quality at Every Step

Our mold production workflow is built around repeatability and reliability:

Full in-house mold making to control every detail
Comprehensive inspection protocols using CMM and optical measurement
Trial sampling to verify performance under actual injection conditions

We aim to minimize variation and maximize uptime on your molding line.

Your Partner for Complex Parts

Our team has rich experience in:

Thin-wall parts
Multi-cavity tools
Inserts and overmolding
Molded-in features with high precision

If your plastic component requires critical geometry, complex surfaces, or multi-part assembly, Dongxinda delivers solutions that work the first time—and every time.

Frequently Asked Questions

Q1: What’s the minimum tolerance you can achieve in mold machining?
A: We routinely achieve ±0.01mm tolerance on critical surfaces, and even tighter upon request.

Q2: Can you assist with validation reports and documentation?
A: Yes. We provide full FAI reports, material traceability, and mold trial videos or photos on request.

Q3: How do you handle mold modifications if needed?
A: Our team can provide rapid engineering changes, sometimes within 48 hours, depending on the scale.
