After 8 years development, ZZ OLD CRAFTSMAN has its own factory, complete tungsten carbide blanks Production line and carbide brazing production line. Management is thinking how to make the factory reduce costs, and achieve continuous development? To build the environmentally friendly factory is a good choice.

Due to the continued high temperature and drought this year, power supply is tight. ZZ Old Craftsmen decided to invest 200,000 US dollars to install solar panels on the roof of the factory. After a month of construction, the 272.16KW rooftop solar project was finally completed. At present, under the condition of sufficient sunlight, it can generate 1600KWh per day. With the abundant power resources, ensure the smooth operation of carbide production while saving electricity costs, not only reduced the carbide production cost, but also guarantee the production delivery, not affected by the shortage of national power resources and power outages

At present, Zhuzhou old craftsman mainly produce carbide blanks, carbide custom products and carbide brazed products. Carbide brazed products are developed by our company through 9 years of continuous investment in capital, manpower, equipment, etc. At present, carbide wear liners, carbide hammers and rotor tips, and liners for refractory brick molds are welcomed by the market and recognized by customers.
For a Tungsten Carbide Wear Parts Factory, ensuring high quality and reducing costs are critical long-term objectives. The primary type of product includes highly durable components like inserts, liners, and nozzles, designed for extreme abrasion and impact resistance.
Key manufacturing processes such as powder metallurgy (mixing, compacting, and sintering) are central to specific production. To achieve mass production efficiency, factories often utilize a streamlined assembly line approach, transforming raw materials into the finished product with high productivity efficiency. Product design is optimized not only for performance but also for manufacturability, helping to minimize material costs and reducing waste—a crucial factor given the expensive nature of tungsten carbide.
Cost management extends to controlling labor costs and energy efficiency. Investing in modern, efficient power supply units and sintering furnaces significantly lowers energy consumption per unit. Furthermore, integrating renewable energies into the power supply helps mitigate environmental impacts and reduce the operation’s overall carbon footprint.
Ultimately, by focusing on advanced processes, waste reduction, and sustainable energy use, a factory can secure a competitive edge. This holistic approach supports a high production volume of superior parts while ensuring long-term viability through responsible manufacturing and reducing costs across the entire operation.
