Wire and cable are manufactured through three processes: drawing, stranding, and cladding. The more complex the model specifications, the higher the repeatability.

1. Draw
In metal press working, the technical process of forcing the metal through the die (pinch roller) under external forces and compressing the cross-sectional area of ​​the metal to obtain the desired cross-sectional shape and dimensions is called metal draw.
Drawing process points: monofilament drawing and strand drawing.
2. Stranded
In order to improve the flexibility and overall degree of wire and cable, two or more single wires are intertwined in a defined direction called stranding.
Stranding process points: Stranded conductors, cabled, braided, wire mounted and entangled.
3. Coating
According to the different functional requirements of wire and cable, special equipment is used to coat different materials on the outside of the conductor. Coating process:
A. Extrusion: rubber, plastic, lead, aluminum and other materials.
B. Vertical package: rubber, wrinkle aluminum strip material.
C. Wrapping: banded paper tape, mica tape, alkali-free glass fiber tape, non-woven fabric, plastic tape, linear cotton yarn, silk and other fiber materials.
D. Dipping: Insulating paint, asphalt, etc.

We focus on high purity alumina, zirconia and silicon nitride as the material for mechanical seal ceramics. Due to this component is able to offer superior anti-wear, anti-chemical, resistant high tempreture and pressure , and low friction with self-lubrication characteristics. In consideration of these features, Ceramic mechanical sealing components have a better sealing performance and a longer service life span than metal and plastic ones. It is likely to be a trendency using ceramic mechanical seals replace metal ones.
The mechanical seal ceramics we manufactured mainly include seal faces, seal ring, seal disc and ball valve and so on.
It's widely used various of oil pump, water pump, valve devices and other many different seal devices.
