Control Quality Process

Firstly, for raw materials, we implement timely Incoming Quality Control (IQC). We exclusively source materials from certified and trusted suppliers who maintain robust quality management systems and possess the necessary certifications, including RoHs, Reach, MSDS, FDA, LFGB, UL, EN549, BPA free, EN71, and more.

Secondly, during the pre-production phase, we provide clients with samples for testing and promptly seal them upon approval.

Throughout bulk production, we execute thorough In-Process Quality Control Sampling (IPQCS), Production Quality Control (PQC), and a final Quality Control (FQC) check after deburring or edge finishing. Our keen focus on issue detection, resolution, and cost-efficiency results in reduced defects and manufacturing costs.

Finally, in the post-production stage, we conduct Outgoing Quality Control (OQC) through sampling inspections to ensure that the final product aligns with our stringent quality standards

Working with Xinjuexin ensures your business and investments are secure, with a strong focus on quality assurance!

Technical supports

Xinjuexin’s expert team is skilled in customizing products to fulfill unique OEM requirements and providing project guidance. Upon approval of our pricing, expect to receive a Design for Manufacturability (DFM) analysis within two working days.

DFM reports act as a vital bridge between product developers and mold manufacturers, proven to enhance efficiency across various industries. In mold-making endeavors, a comprehensive DFM report serves as the foundational step for success. By anticipating potential issues, you can reduce manufacturing risks.

Even if you lack 3D drawings and only possess design concepts or samples, we can assist in creating the necessary 3D drawings.

At Xinjuexin, if you can envision it, we have the capabilities to bring it to life!
