Dawang Metals Achieves DNV Marine Classification Certification

Following our certifications from ABS, CCS, BV, and LR, Dawang Metals has now officially obtained DNV (Det Norske Veritas) certification.

DNV is one of the world's leading marine classification societies, with standards widely recognized in the marine, offshore, and energy industries.

With multiple international marine classification certifications, Dawang Metals is well positioned to supply certified castings for customers across global shipbuilding and offshore projects.

We remain committed to strengthening our quality systems and manufacturing capabilities to deliver reliable casting solutions worldwide.

Traditionally, foundries entered the project after the design was complete.
Today, more customers involve their casting suppliers during the Design for Manufacturability (DFM) stage.

Why?
✔ Optimize the casting process before production
✔ Plan machining allowances and dimensional tolerances early
✔ Reduce the risk of shrinkage, distortion, and other casting defects
✔ Minimize design changes, development time, and overall project cost

For complex castings, successful manufacturing starts long before the first pour.
The earlier DFM begins, the smoother the project moves forward.

Why Do We Keep a Sample Block from Every Heat?
At Dawang Metals, a sample block is produced and retained before every heat is poured.

It is more than just a test specimen—it is a critical part of our quality traceability system.
✔ Verification of material properties
✔ Production record retention
✔ Support for quality analysis
✔ Compliance with customer traceability requirements
Quality is not only about inspection results.It is also about ensuring every casting can be traced back to its source.

Why Is Early Process Evaluation Becoming More Important for Complex Castings?

In complex castings, many manufacturing risks are determined before production starts:
● Shrinkage and feeding design
● Distortion risk
● Machining allowance
● Gating layout
As customers demand tighter tolerances and higher consistency, more projects are emphasizing DFM and early-stage process evaluation.

At Dawang Metals, we evaluate casting feasibility, machining requirements, and inspection standards early in the project stage to reduce risks before production begins.

Good manufacturing is not only about making parts —it is about solving problems early.

When a part design becomes more complex, why do more engineers choose investment casting instead of welding processes?

In modern manufacturing, many components require complex geometries, thin-wall designs, and integrated functional structures. For these types of parts, using welding processes often means more manufacturing steps, and it can also introduce issues such as welding deformation, stress concentration, and dimensional inconsistency.

This is where investment casting shows its advantages.

With the investment casting process, complex internal and external features can be formed directly during casting, such as:
✔ Complex curved geometries
✔ Deep holes or irregular channels
✔ Thin-wall structures
✔ Integrated multi-function designs

This approach can significantly reduce welding and subsequent machining operations, improve material utilization, and lower overall manufacturing costs.
At Dawang Metals, we produce complex casting components for global OEM customers in industries such as agricultural machinery, valves, pumps, and industrial equipment. By optimizing casting design and manufacturing processes, we help our customers achieve more efficient and reliable production solutions.
Complex parts don’t necessarily require complicated manufacturing.
Choosing the right process can make all the difference.
