Introduction
As an experienced sourcing agent in China, we specialize in helping international clients identify and verify trustworthy OEM manufacturers across a wide range of industries.
Our comprehensive sourcing process includes factory research, trade show visits, supplier audits, and production monitoring, ensuring each project is executed seamlessly from start to finish.
One sourcing project involved PU foam products, which are extensively used in chairs, vehicles, medical devices, and packaging materials. Here’s how we efficiently searched for, verified, and selected the perfect PU foam OEM factory in China to meet our client’s needs.
The Search Process
Our research commenced with an emphasis on cities located near major ports, which are significant hubs for PU foam manufacturing.
Following a comprehensive evaluation, we identified and shortlisted five factories that met the following criteria:
-
A minimum of 10 years of experience in PU foam production
-
Consistent and stable financial performance
-
A proven record of exports complemented by relevant quality certifications
Each of the selected factories submitted product samples, detailed quotations, and comprehensive production information for further evaluation.
Factory Comparison
We compared their:
-
Samples and material density
-
MOQ and lead time
-
Payment terms and warranty policies
Two factories stood out in both product quality and pricing.
However, during the verification stage, one supplier — located in Zhejiang — refused our request to view their production line.
That raised some concerns about transparency and process control.
Reasons for Selecting Jinhe
Following a comprehensive evaluation, we selected Jinhe as our esteemed PU foam OEM partner.
This decision was influenced by the following key considerations:
-
Their consistent commitment to an open and transparent approach throughout all stages of the collaboration process.
- The ability to provide high-quality PU foam protective components specifically designed for playground and amusement equipment.
-
The factory's strategic location, situated just 30 minutes from our office, facilitates efficient and convenient on-site quality inspections whenever required.
-
Their exceptional support in areas such as sample testing, mold development, and pre-shipment inspections underscores their unwavering dedication to quality assurance and cooperation.
The combination of their extensive production capabilities and efficient communication practices has established a strong foundation for a confident and enduring partnership.
