Building on the present and looking to the future, Jinduicheng Construction adheres to the development philosophy of "Pioneering and Striving for Excellence."It is dedicated to serving customers, aiming to meet personalized needs, adheres to a work approach focused on accelerated transformation and steady development, and follows the business principles of legality, safety, and economy.Rooted in Shaanxi and expanding nationwide, it strives to become a leading comprehensive service provider in Shaanxi's mining construction and civil construction sectors.

(I) Construction Engineering

Shaanxi Jinduicheng Construction Engineering Co., Ltd. (abbreviated as "Jinduicheng Construction") is a wholly-owned subsidiary of JDC Group. It was restructured from the former Engineering Company of JDC Group in April 2018.

The company holds the following qualifications:

• Grade I Qualification for General Contracting of Mine Engineering Construction

• Grade II Qualification for General Contracting of Building Construction

• Grade II Qualification for Professional Contracting of Steel Structure Engineering, Building Decoration and Finishing Engineering, and Waterproof, Anticorrosion and Thermal Insulation Engineering

It has been certified against the standards for Quality Management Systems, Environmental Management Systems, Occupational Health and Safety Management Systems, and the Quality Management Specification for Engineering Construction Enterprises.

(II) Tungsten Industry

In line with the strategy of "Prioritizing Both Ends and Supplementing the Middle," the company actively deploys and develops the complete tungsten industrial chain covering "tungsten concentrate – ammonium paratungstate – tungsten oxide – tungsten powder."It spans all segments from mining, smelting and processing to trade, forming a virtuous cycle of collaborative upgrading across the entire industrial chain and establishing an advanced tungsten-based materials industrial base.It develops high-performance refractory metal materials and a series of core products such as tungsten tubes, tungsten plates, tungsten crucibles, and tungsten-molybdenum parts for the electronics industry.This advances the localization of key tungsten industry products and ensures independent and secure supply.

(III) High-End Equipment

1. In-Situ Vacuum Induction Melting Gas Atomization Furnace (ISVIGA-100)

The In-Situ Vacuum Induction Melting Gas Atomization Furnace integrates vacuum induction melting (for temperature control, degassing, and impurity removal), in-situ self-generation (forming uniform reinforcing phases), and gas atomization powder production technology.It can produce high-purity alloy powders with fine grains and dispersed reinforcing phases, balancing both purity and performance. It is used for preparing high-performance structural and functional alloy powders for applications in aerospace superalloys and the automotive sector.

2. 100-Kilogram Class Controllable Shock Wave Mineral Processing Crushing Equipment

This is a new type of mineral processing equipment that achieves efficient ore crushing and mineral liberation based on the principle of controllable release of high-energy shock wave energy.

It features controllable energy release, high electrical energy conversion efficiency, and a low risk of over-crushing. It can significantly reduce energy consumption, improve mineral processing recovery rates, and enable the application of pulse power sources in ore crushing production scenarios.It is suitable for pre-processing refractory ores (such as those with fine dissemination particle size and significant hardness differences).
