Frequently Asked Questions

Why should I choose New Denghui over other mold makers?

We combine precision mold manufacturin with in-house high-clamping-force injection machines, including two-shot and three-shot capabilities. This means we can take you from design to finished parts in one place, reducing your coordination effort, project risk, and time to market.

What certifications do you have?

Our quality management system follows ISO 9001 standards and IATF16949.

How do you handle design changes after tooling starts?

If you need to change part design after mold manufacturing has begun, we will evaluate the impact on timeline and cost, provide a clear proposal, and proceed only with your approval.



Q8: Do you ship molds worldwide?

Yes. We have experience shipping molds to customers worldwide. We handle proper packaging (rust protection, wooden crates) and can arrange sea, air, or express delivery based on your needs.

Q6: How do you control mold quality?

We have a structured quality control process including incoming material inspection, in-process inspection at key machining steps (electrode, core/cavity dimensions), and final CMM inspection of first articles. All inspection reports are documented and traceable.

Do you have in-house injection machines for trial runs and production?

    Yes. We have multiple high-clamping-force injection machines on-site, including two-shot and three-shot machines. This allows us to run trials and even offer contract manufacturing if you need us to produce parts for you.

Do you provide sample parts before mass production?

Yes. We conduct trial runs and submit first-article samples with a full inspection report (including CMM measurements). You will approve samples before we proceed to mass production.



Can you help with part design optimization?

Yes. We offer DFM (Design for Manufacturing) reports to optimize part design for better moldability, shorter cycle times, and lower costs. Our engineers work with you early in the design phase to identify potential issues before tooling starts.



What is your mold life expectancy?

Our precision molds are designed for over 1 million shots. We use high-quality mold steel and advanced heat treatment processes to ensure durability and long-term stability.



What is your mold manufacturing lead time?

Typical lead time for precision injection molds is 6~8 weeks, depending on mold complexity and number of cavities. Two-shot and three-shot molds may take 8~10 weeks due to more complex rotary/platen mechanisms. We provide a detailed schedule upon order confirmation.
