Attribute：
Production technology：
the production process is as below: Isostatic pressure - intermediate frequency sintering - machining - tungsten tube finished product
Packing, transportation and storage：
The products are packed into wooden cases with shockproof and moisture-proof materials, and the wooden cases are packed tightly with soft materials. Products are not packed in wooden cases, need to be wrapped in soft plastic paper, and then fixed on a strong support frame, to ensure the stability of the product.
Products in transportation should pay attention to shock-proof, moisture-proof, pressure-proof, and prevent secondary pollution.
If the demander has special requirements on the marking, packaging, transportation and storage of the products, both parties shall negotiate.
