From Requirement to Controlled Production

A visible development process helps customers understand how requirements become an approved production direction.

01

Requirement Review

Finished product, processing method, target properties, destination market and current material issue.

02

Formulation Direction

Rigid or flexible direction, hardness, color, performance targets and documentation scope are defined.

03

Sample Development

The sample plan is confirmed after requirement review; qualified projects can be sampled as fast as 2 days.

04

Testing & Customer Validation

Agreed properties are tested and customer line-trial feedback is reviewed.

05

Specification Handover

Confirmed limits, batch checks, documentation and change boundaries are recorded before production.

People Behind the Development Work

  • More than 30% of employees work in R&D and technical roles.
  • Technical work covers formulation, testing, processing feedback and production transfer.
  • Customer requirements and trial feedback are recorded before a formulation direction is finalized.
  • Long-term technical cooperation with four universities — Zhejiang University, Hohai University, Xi’an Jiaotong University and Hubei University of Technology

Application Development Support

Application & Requirement Review

Finished product, process, target properties, market and current material issue are reviewed first.

Sample Development

Sample development can be completed as fast as 2 days after requirements are confirmed.

Physical Testing & Data Review

Agreed properties are checked and recorded for customer evaluation.

Customer Trial Feedback Review

Line-trial observations are reviewed to refine processing fit where needed.

Production Transfer & Batch Specification

Approved requirements are transferred into production and batch-release controls.

R&D Capability You Can Verify

Company data, certificates and technical records should be visible and matched to the claim being made.
