Meet Our Structural Design & Manufacture Expert
With over 25 years of experience in structural design and tooling development,
Wang Wenguang (Tooling & Structural Design Lead) plays a key role in bridging engineering design and manufacturing execution at BST.
He has worked on projects for global brands including Motorola, Sony Ericsson, Xiaomi, Hyundai, and Mercedes-Benz — handling complex components where precision, manufacturability, and reliability must align.
Engineering insight from real production challenges
In real-world manufacturing, problems are rarely theoretical — they happen on the production floor.
In one automotive project, a component experienced deformation and cracking immediately after mold ejection. This issue made stable mass production impossible.
By analyzing the root causes, Wang and the team implemented a combination of solutions:
- Adjusting material composition
- Optimizing mold friction conditions
- Enhancing the ejection mechanism
The result was a stable process and successful production.
In another project, an overly tight tolerance on a non-critical dimension led to failed inspections, rejected batches, and production stoppage.
After confirming that this dimension had no impact on assembly performance, the team worked with the customer to optimize the tolerance range.
As a result:
- Yield improved
- Production resumed smoothly
- Overall cost was reduced
precision should be applied where it matters — and design decisions must support manufacturability.
From craftsmanship to engineering mindset
Beyond engineering, Wang enjoys hands-on craftsmanship, cycling, and outdoor activities such as hiking.
These interests reflect his professional mindset:
- Attention to detail
- Patience in problem-solving
- Continuous improvement
Whether in a workshop or on the road, the same principle applies —
refine, optimize, and keep moving forward.
