WEILAN MFG Hosts Bao'an District Children's Industrial Study Tour at Songgang Factory

On March 14, 2026, WEILAN MFG opened the doors of its Songgang production base in Shenzhen to more than 30 children from across Bao'an District. The visit was part of the 2026 Bao'an Child-Friendly Industrial Study Tour, a government-backed STEM education initiative organized by the Bao'an District Women's Federation and the Songgang Sub-district Office. The program is designed to give young students first-hand exposure to real manufacturing environments — turning abstract classroom concepts into tangible, observable processes.

For WEILAN MFG, participation in this program reflects a straightforward belief: precision manufacturing is worth understanding, and the best way to understand it is to see it up close. The afternoon tour took students through the full scope of WEILAN MFG's vertically integrated operations — from the engineering center where products are designed and validated, through the mold making workshop, into the injection molding production floor, and finally to the assembly area where finished components come together.

Welcoming the Next Generation

The students arrived at WEILAN MFG's facility in the early afternoon, greeted by event organizers and WEILAN MFG staff. Each child received a welcome pack — fittingly, a miniature injection-molded luggage case, a small but concrete example of the kind of precision plastic products that WEILAN MFG manufactures every day.

From Blueprint to Reality: The Engineering Center

The tour began in WEILAN MFG's technical center, where an engineer walked the group through the lifecycle of a product — from initial concept and structural design, through mold flow analysis, to final mold fabrication. For most of the children, this was their first encounter with the idea that every plastic component they use daily — from phone cases to medical devices — starts as a digital model and goes through rigorous engineering validation before a single part is produced.

The presentation was designed to be accessible without being oversimplified. Engineers explained how mold flow simulation predicts how molten plastic will fill a cavity, where potential defects like sink marks or weld lines might form, and how design adjustments at this stage prevent costly problems downstream.

Walking the Production Floor

Mold Making Workshop

The first production stop was the mold making workshop, where students saw precision CNC machining centers, EDM equipment, and the steel mold components that form the backbone of injection molding. A WEILAN MFG engineer explained how mold cavities are cut to tolerances measured in microns — thinner than a human hair — and why this level of precision directly determines the quality of every part that comes off the production line.

Injection Molding Production

Next, the group moved into the injection molding production area. Here, the children watched as plastic pellets were fed into electric injection molding machines, heated, and injected under high pressure into closed molds — emerging seconds later as fully formed precision components. The speed and repeatability of the process visibly impressed the young visitors. WEILAN MFG's production floor runs Sumitomo and Zhafir all-electric machines, the same equipment used for medical-grade and automotive-grade production, delivering the shot-to-shot consistency that demanding applications require.

Assembly Area

The final production stop took students through the assembly area, where individual molded components, electronic modules, and sub-assemblies are integrated into finished products. The children saw how injection-molded parts are just one piece of a larger manufacturing puzzle — and how WEILAN MFG's vertically integrated model allows the entire sequence, from raw material to boxed product, to happen under one roof.

Why This Matters

Programs like the Bao'an Child-Friendly Industrial Study Tour serve a purpose beyond a single afternoon's education. They connect young people with the industries that drive their local economy, demystify manufacturing as a career path, and build an early appreciation for the engineering discipline behind everyday objects. For a district like Bao'an — home to a dense concentration of precision manufacturing enterprises — these connections matter.

WEILAN MFG has been rooted in Songgang for over a decade, building a reputation as a precision injection molding partner for medical, automotive, and consumer electronics customers worldwide. Opening our facility to the local community is a natural extension of that commitment. Manufacturing excellence does not exist in isolation — it depends on a pipeline of curious, technically minded people who understand what it means to turn a design into a physical product, reliably, at scale.

We thank the Bao'an District Women's Federation and the Songgang Sub-district Office for including WEILAN MFG in this program, and we look forward to welcoming more young visitors in the future.
