Precision Mold Craftsmanship: Elevating Injection Molding Through Fine Detail

At Dongxinda Mould Technology Co., Ltd., we believe that the finest products begin with the finest tools. That’s why we emphasize not only the structure of the mold but also its precision detailing and surface finish. Our dedication to craftsmanship sets your molded parts apart—right from the first shot.

The Power of Mold Precision

Whether your component is cosmetic or functional, the quality of the mold determines the quality of the final part. Even the smallest imperfection can lead to flashing, uneven finishes, or warping. At Dongxinda, we integrate:

• Ultra-precision CNC machining (±0.005mm tolerance)

• Mirror-grade polishing for transparent parts like lenses and housings

• Laser texturing and EDM patterning for anti-slip or aesthetic surfaces

• Fine-tuned venting and gating to prevent flow lines and defects

Advanced Surface Treatment Techniques

Our team doesn’t stop at machining. We incorporate advanced surface treatments to improve durability, mold-release, and appearance:

• Nitriding & PVD coating for high-wear resistance

• Hard chrome plating for corrosion protection

• SPI-standard polishing (A1 to D3 finish levels) for customized appearance

• Etching services for branding, logos, and unique surface textures

This makes our molds ideal for automotive trim, consumer electronics, medical enclosures, and transparent parts.

Quality Without Compromise

Every tool built at Dongxinda undergoes thorough quality control:

• CMM inspection reports on core and cavity

• Mold trial videos and dimensional validation before delivery

• Mold life guarantees based on production volume and material use

From single-cavity prototype molds to multi-cavity high-production tools, our precision defines your product’s performance and perception.

Frequently Asked Questions

Q1: Can Dongxinda achieve optical-grade polishing for PC or PMMA parts?
A: Yes, we offer mirror polish finishes (SPI A1) for high-transparency components used in lighting, medical, and cosmetic packaging industries.

Q2: How do surface textures affect injection molding cycle time?
A: Proper textures can improve mold release and reduce sticking, leading to shorter cycle times and less wear.

Q3: Do you provide sample runs before mold shipment?
A: Absolutely. We conduct T0 or T1 trial shots and send detailed sample evaluation reports before mold delivery.
