Thanks to years of precipitation, we have an excellent supply chain with high quality and high efficiency. Our suppliers are industry-leading enterprises and companies, they have excellent quality control capabilities, and provide high-level services. Most of our suppliers are also listed in the AVL of our high-end customers. Together with us, they provide end customers with high-quality products.

We have introduced advanced ERP systems many years ago, and recently introduced PLM management systems. Our professional system maintenance team can flexibly customize system functions according to the special needs of customers, and continue to provide the most powerful support for efficient logistics management.

We started building the MES system very early to lay a solid foundation for the development of Industry 4.0 and the construction of smart factories. Our advanced warehouse management system, which accurately manages and tracks each batch of materials, is the cornerstone of overall cost and quality control.

We have a number of advanced production lines, while insisting on continuous upgrading and transformation, using automated tools as much as possible, and making unremitting efforts to improve production efficiency and product quality. As an intelligent advanced factory, we have high-level testing and automation equipment in the industry, and we continue to invest in this.

The neat high-tech SMT workshop is one of our highlights. We have dozens of high-speed, high-precision equipment. For this reason, we can provide customers with products with extremely high cost performance and high quality assurance.

We apply advanced online testing equipment to ensure the consistency of mass production, such as ICT, AOI and ATE. For smart charger or PCBA control board products, we also apply online calibration and multi-function monitoring stations to ensure 100% shipment testing; and the test data can be stored in the database according to the product code to provide the original basis for quality traceability.

Our systematic and comprehensive quality control is everywhere. We have an industry-leading quality management system, using advanced management tools such as APQP, PPAP, PDCA, FMEA, MSA and SPC, we have obtained ISO9001 certification since the establishment of the company, and we have completed internal training and are about to obtain TS16949 certification.

Zerda R&D department has dozens of experienced and capable design engineers. We can provide customers with professional and agile design services. At the same time, engineers have an in-depth understanding of customers' products, and can provide the most suitable suggestions for the different characteristics of customers' products to help customers create perfect products. Our team is constantly growing, and the introduction of high-level talents is the source of motivation to improve design capabilities.

We are not only good at electronic circuit design, structure and software design are also strong points. We can design the product structure according to the customer's ID or our own appearance, and complete a complete set of processes such as mold opening and injection molding. In addition, our software engineers are very good at understanding the customer's functional requirements and transforming them into optimal algorithm codes in combination with international industry standards. Now we have dozens of invention patents, utility models or software copyrights, and we are constantly striving to innovate.

Relying on high-precision and high-stability debugging and testing instruments, we can ensure that the product parameters are the most reasonable, and can meet international standards, industry standards, company design specifications and various indicators required by customers. At the same time, accurate, rigorous and complete test items provide a guarantee for us to design the most cost-effective products.

We have a quick response and perfect process sample production team, which can provide customers with the samples they need in time to help customers complete the design of the whole machine quickly. More importantly, all our samples must undergo rigorous testing to ensure high quality while delivering quickly.

As a third-party verification within the company, the role of DQA is indispensable and very important. At each design node, we will apply for internal independent verification to ensure the correct expression of customer needs. The DQA laboratory has complete instruments and equipment, which can cover most important test items. At the same time, the DQA laboratory issues professional test reports, which can be used as verification of design results and quality assurance of customer samples.

We have a complete reserve of safety certification and a professional team of engineers. The company has more than 3000 various safety test reports and certificates, and this number is still growing. As a responsible company, we ensure that each product strictly meets the requirements of relevant safety regulations. This has been paid enough attention in the early stage of product design, and it has been throughout the entire process of raw material selection, manufacturing, and delivery of finished products.
