Wire Electrical Discharge Machining (WEDM) belongs to the category of electrical machining. When the couple of the former Soviet Union Lazarenko studied the phenomenon and cause of damage to the switch contacts by spark discharge corrosion, they found that the instantaneous high temperature of electric spark can The local metal is melted, oxidized and corroded, thereby initiating and inventing the electric discharge machining method. The wire cutting machine was also invented in the former Soviet Union in 1960. China is the first country to be used for industrial production.
Distinguish between fast wire cutting, medium wire cutting and slow wire cutting. 1: The wire-traveling speed of the fast-wire EDM wire cutting is 6 ~ 12 mm / s, and the electrode wire performs high-speed reciprocating motion, and the cutting accuracy is poor. 2: Medium wire EDM wire cutting is a new technology developed in recent years that realizes the frequency conversion multiple cutting function on the basis of fast wire cutting. 3: The wire-traveling speed of the slow-wire EDM wire cutting is 0.2mm / s, and the electrode wire performs low-speed unidirectional movement, and the cutting accuracy is high.
WEDM is widely used in the application of high-precision parts such as Mold Parts, automobile parts, mechanical parts, medical parts, and motor parts.

Carboxymethyl cellulose(CMC) in Pharm./medical application:
Sodium Carboxymethyl Cellulose(CMC) is the sodium salt of Carboxymethyl cellulose derived from natural occurred fiber.It is anionic polymer with clarified solution dissolved in cold or hot water.
Our high performance CMC can be used in various functions in pharm./medical application.It has outstanding chemical stability and emulsification capability,acid and alkali-resistant,neutral in solution.It effectively improves the disintegration or medicine tablets and prompotes the adsorption of the effective elements.
Our CMC can be used for dental care in tooth filling, artificial teeth,paste base for adhesion,tablet,etc.
Brief Properties of our CMC Pharm.grade
High Degree of substitution
High degree of substitution smooth the rheology of the aqueous solution and give improved compatibility.
