R&D

Based on basic disciplines such as electrochemistry and materials science, Telford Technology research and development platform conducts the process research and development of copper foil products. It has set up Everest Laboratory and Kuafu Laboratory, and built a systematic research and development system from basic research of crystal structure, simulation analysis, modular development of process links to product sample testing and evaluation. And formed the copper foil basic theory and micro research, copper foil ultrafine coarser as the representative of the core technology system.
Advanced detection and simulation technologies such as cyclic voltammetry stripping technology and COMSOL multi-physical field simulation technology have been introduced into the platform, and the first simulation laboratory in the industry has been established. Advanced equipment such as ultra-high resolution SEM, electron back scattering diffraction analysis EBSD, inductively coupled plasma emission spectrometer, laser confocal microscope and vector network analyzer are equipped to support the continuous upgrading of copper foil manufacturing.
In terms of industry-university-research cooperation, the company has carried out cooperation and exchanges with Peking University, Xiamen University, South China University of Technology and other leading institutions, to keep up with the forefront development of the industry and maintain the ability of continuous innovation and creation. Through the research and development platform and the transformation of results, defu Technology will promote the continuous upgrading of copper foil manufacturing technology and promote the sustainable development of copper foil industry. To provide customers with better products and services.

Intelligent manufacturing platform

Intelligent manufacturing platform

Defocet intelligent platform integrates a variety of application systems including ERP, MES, QMS and BI, with sales, resources, production and service as the core, aiming to realize the full cycle management of enterprise orders.

Breakthrough in the flexible intelligent production line for copper foil production, visualization of product quality management, equipment fault prediction and fault diagnosis and other key technologies, and the introduction of a large number of intelligent production, detection, storage equipment, to achieve efficient enterprise operation management, intelligent manufacturing level of the whole process of copper foil production is leading the industry.

Soft power advantage

Soft power advantage

Defu Technology focuses on quality, realizes lean operation management and strict quality control management, and implements standardized system management. The company has passed IATF16949 automotive industry quality management system certification, in the copper foil industry to take the lead in the implementation of AIAG American automotive industry action Group automotive industry core tools. With the introduction of German customers, the company adopted the core tools of VDA German Automobile Industry Association, successfully implemented the German Automobile Industry Association VDA6.3 process audit standard, and trained a group of excellent auditors. Through lean production, Six Sigma and other management strategies, to achieve lithium copper foil to extremely thin copper foil upgrade, electronic circuit copper foil to high performance HTE copper foil, 5G communication copper foil iteration, and give consideration to the product mechanical strength, conductivity, product consistency and battery safety and other aspects of continuous improvement, so that defo products become the industry quality assurance.

Talent team building

Talent team building

Defu Technology has insisted on scientific and technological innovation for many years, and has a strong R & D team. At present, the R & D team consists of more than 200 people, including 10 doctors, 1 professor-level senior engineer, 2 senior engineers and more than 100 engineers.
The company introduced professional lean production guidance institutions, and conducted professional training for R&D, production, technology, quality control and production support departments of the whole company as planned. At present, 25 employees of the company have passed the Six Sigma Black Belt theory examination, and one project has been awarded a black belt certificate. The team has professional technical ability to provide customers with professional, high quality service.

Industrial chain advantage

Industrial chain advantage

The industrial chain advantage of defu technology is reflected in the following aspects:
First, supply chain layout. The company has reached strategic cooperation with Baiyin Nonferrous Group to ensure cathode copper supply, providing strong support for copper foil production capacity construction and release.
Second, the production capacity advantage, the company now has the copper foil manufacturing capacity of 125,000 tons/year, the production capacity has an absolute leading position in the domestic industry, to provide guarantee for the copper foil supply to downstream customers.
The third is the extension of the industrial chain. The company has invested and established a number of upstream subsidiaries of the industrial chain, including core raw materials and spare parts such as additives (potions), cathode rolls, and anode plates, so as to improve procurement efficiency, avoid operating risks brought by price fluctuations of upstream raw materials and spare parts, and significantly improve the company's anti-risk ability.
