On May 13, a customer group from South Korea visited Yujin Plastic for an on-site factory audit and technical exchange focused on windshield wiper blade manufacturing, production control, and OEM cooperation possibilities.
For most overseas buyers, especially in the automotive aftermarket, a factory visit is not a formality. It is a direct verification process—checking whether a supplier’s production capability and quality system can truly support long-term bulk supply.

The meeting was led by the General Manager of Yujin Plastic, who welcomed the Korean delegation and gave a structured introduction to the company.
Instead of focusing only on products, the discussion started from the factory level:
Company development history
Core brand system
Product categories and application coverage
OEM and export experience
Particular emphasis was placed on the company’s strength in rubber strip R&D and wiper blade product development, as well as the performance of its brands in different markets.
From the buyer’s perspective, this stage is mainly about one question: Is this factory actually capable of stable production, or just a trading setup?

After the company introduction, the technical team walked the Korean visitors through the core structure and performance logic of the wiper blades.
Rubber vulcanization process control
Weather resistance performance testing
Noise reduction structure design
Fitment solutions for different vehicle models
Durability under long-term usage conditions
The Korean buyers paid close attention to how the product performs under different seasonal conditions, especially in environments with temperature variation, rain, and snow.
During this stage, discussions became more practical, including:
Product adaptation for Korean vehicle models
OEM customization and private label requirements
Packaging design options for local distribution
Production lead time for bulk orders
After the technical session, the delegation moved into the production area and laboratory for a full on-site inspection.
This is usually the most important part of a factory audit.
Incoming raw material inspection
Rubber extrusion and molding process
Wiper blade assembly line
In-process quality checks
Final product inspection before shipment
Rather than relying on certificates or presentations, the Korean buyers observed how each process is actually controlled on the shop floor.
Whether production steps are standardized
How operators handle consistency
How defects are identified and removed
Whether inspection is continuous or random

In the testing laboratory, Yujin Plastic demonstrated its quality control procedures for finished wiper blades.
Durability cycle testing
Weather resistance simulation
Noise and friction performance checks
Batch sampling inspection
For export buyers, especially from developed automotive markets like South Korea, the key concern is not whether a sample works—but whether large-volume production stays consistent over time.
From this visit, one thing became clear: experienced buyers do not judge suppliers only by product samples or price.
Can production scale remain stable under OEM orders?
Is quality control embedded in the process or only at the end?
Can the factory support customization without affecting consistency?
Is there real engineering capability behind the product?
In other words, the factory itself becomes part of the product decision.
This visit was not just a routine business meeting, but a step toward deeper understanding between both sides.
Through direct communication and on-site inspection, the Korean customers gained a clearer view of Yujin Plastic’s manufacturing system and quality control capability.
For Yujin Plastic, the visit also reinforced its focus on:
Stable OEM production support
Continuous product improvement
Flexible customization services
Reliable supply for global distributors
As global sourcing becomes more demanding, transparency in manufacturing is no longer optional—it is part of the trust-building process.
