Behind the Build: Jingzhan Mould’s 20-Year Transformation

Behind the Build: From Survival to Shared Growth Inside Jingzhan Mould’s 20-Year Journey of Trial and Breakthrough

In our “Behind the Build” series, we explore the human stories behind China’s precision factories — the people who quietly power global manufacturing.
This time, we visit Suzhou Jingzhan Mould Technology Co., Ltd. and meet its founder Lan Junfu, whose twenty-year path mirrors China’s manufacturing evolution: from survival and persistence to collaboration and shared progress.

 

Founding Vision Built on Survival

Before 2020, Lan Junfu lived by a simple rule: work harder than everyone else.
That belief carried him from an apprentice in a tin-roofed workshop managing ten machines alone to the owner of a mould-making factory in Suzhou.

But as orders increased, profits stayed flat and clients quietly disappeared.
“It felt like pressing the accelerator at full speed,” he said, “but realizing the car wasn’t moving forward.”

That moment changed everything. He realized that effort alone would no longer sustain growth. He had to build smarter systems and longer-term partnerships.

From a Humble Start to Technical Mastery

Lan’s first steps into manufacturing came from necessity, not ambition.
Growing up with little, he learned early that skill was his only escape. At 18, he left home for a mould factory in Guangdong. Summers were suffocating; rest was rare. “Nobody taught me,” he recalls. “I just learned while working.”

After saving his first 10,000 yuan, he joined a mould design course — and was rejected everywhere for lacking experience.
So he returned to the shop floor, determined to learn every process himself.

He treated each factory like a classroom, moving frequently to gain new knowledge.
“Some places I stayed only weeks,” he said. “Even if I didn’t get paid, I didn’t want to waste time when there was nothing left to learn.”

That curiosity became discipline. At a foreign-owned enterprise he climbed from technician to full workshop manager, mastering both production and people. “I didn’t know exactly what I wanted,” he said, “but I knew standing still wasn’t an option.”

 

Starting from Zero — and Below

In 2012, after a decade of saving 180,000 yuan, Lan and his wife invested everything to start a small factory. The space was shared, the machines second-hand — but the dream was real.

Within months, disagreements with a partner forced him to start over from nothing. “I left everything behind — equipment, clients, even drawings. All I had left was belief.”

He borrowed small amounts from friends, bought a grinder, a milling machine, an old scooter and desk — and began again.

With no network, he used map apps to cold-call nearby factories — sometimes 100 calls for one meeting. “One chance felt like winning the lottery,” he smiled.

His breakthrough came with a Shanghai optics customer. When asked how many people he had, he replied honestly: “Just me, one grinder, and one milling machine.” The client stood up to leave. Lan stopped him and wrote a full mould proposal on the spot — three hours of detailed parameters, risks, and cost estimates.

The client returned, impressed by his persistence, and gave him a small order. Lan delivered it flawlessly, cutting a 45-day lead time to 25. That was his first official contract — and the birth of Suzhou Jingzhan Mould.

Learning to Build, Not Just Work

In the following years, he cold-called hundreds of prospects and survived on short-term jobs. By 2020, revenue reached ¥10 million but profits stayed thin.
He realized: survival was no longer the goal — structure and learning were.

He began studying digital management, lean processes, and client lifecycle planning.
He built internal workflows for project tracking, role clarity, and customer communication.

He also redefined what makes a good client: “The best partners are those who innovate and grow with you,” he said. “They push you to improve and reward you with long-term trust.”

One such partnership began in 2016. Both companies were small workshops experimenting with medical components. Today that client has over ¥2 billion in annual sales — and Jingzhan remains a core supplier.

 

Tackling Complex Medical Challenges

Lan’s biggest breakthroughs came from medical projects that demanded precision and speed.

During the early pandemic, a client requested nucleic-acid test tubes — no drawings, just dimensions. Typical development takes 45 days; Lan’s team finished in 7, iterating live until sealing tests passed.

Another case involved a disposable throat inspection tube whose welded seam had to be perfectly smooth. A larger factory failed for months; Lan’s team solved it in two weeks through mould redesign and polishing optimization.

These wins brought Jingzhan into the client’s permanent supplier system.
Within five years, factory output grew eightfold — proof that precision and reliability pay off.

Collaboration Over Competition

“No factory can do everything,” Lan said. “Sometimes the smartest move isn’t buying new machines — it’s finding the right partner.”

Many of his R&D-driven customers need dozens of components using different processes. Instead of managing multiple vendors, they now rely on Jingzhan to coordinate full-chain delivery — from machining to moulding, assembly, and testing.

Through Haizol’s digital platform, Lan found a faster, clearer way to locate capable partners.
“We’re both supplier and purchaser,” he said. “Haizol helps us identify verified factories across regions — everything becomes transparent and traceable.”

One large assembly project with 300 parts once required dozens of suppliers. After Jingzhan restructured production using Haizol’s partner network, monthly output tripled while rework and costs dropped sharply. Sometimes collaboration even meant losing money.
“We once outsourced a precision part at twice our quoted price,” Lan recalled. “But we delivered on time and protected the client’s trust. That trust brought repeat business for years.”

 

Co-Creation — The Future of Manufacturing

Today, Lan sees himself not just as a manufacturer or coordinator, but as a co-creator. “Many startups have great ideas but no manufacturing partner willing to stay through early chaos,” he said. “We want to be that partner.”

He now joins clients’ R&D stages early — co-designing, prototyping, and sometimes co-investing.
One medical project developed this way now generates nearly ¥10 million a year.

“The role of manufacturing is changing,” he said. “It’s no longer only about making, but about creating together.”

Toward a Collaborative Future

Factories like Jingzhan represent the quiet strength behind China’s manufacturing growth — leaders who built skills from the ground up and now drive the shift from individual effort to collaborative intelligence.

Haizol is building that same ecosystem digitally — connecting engineers, factories, and innovators across regions and disciplines. For international sourcing teams, that means faster quotes, clearer communication, and verified partners who share accountability from design to delivery.

Twenty years after that first train ride south, Lan Junfu now leads a team capable of producing medical-grade precision parts and global-level reliability — showing that the future of sourcing lies in trust, not just cost.
