Silicon carbide electric heating elements are widely used in a variety of high-temperature electric furnaces and other electric heating equipment in the industries of magnetic materials, powder metallurgy, ceramics, glass, metallurgy and machinery.
The two packing methods we use are plywood box packing and solid wood packing, with the solid wood box requires a fumigation certificate. Depending on the various products, we will tailor the proper packaging box; Plastic foam measuring 2 cm to 3 cm thick is placed within the box and secured with row nails. To maintain the products safety during shipment, packing tape is typically used.
We can clearly know how to ensure the output of products and quality stability and manufacture silicon carbide ceramic products with superior performance.
Newthink New Material Co., Ltd. is located in Qingdao West Coast New Area, China. Established in 2011, it is a professional manufacturer engaged in the research, development, production and sales of silicon carbide ceramic products, with two subsidiaries; and sub-brands.
