In the process of manufacturing tungsten carbide blades, the equipment we use is a vacuum sintering furnace. The sintering process will determine the characteristics of the tungsten carbide blades.
Sintering is like giving Tungsten Carbide Blades their "final steam baking." The "heat control" (temperature and time) and the "environment" (vacuum) determine the final "physical quality" of the blades.
The specific impacts are reflected in the following aspects:
1.Density and Strength:
Sintering is the process of "firming up" the powder compact. Insufficient temperature or time leaves internal voids in the blade, like an "undercooked bun," making it soft and brittle. With the right "heat control," it becomes very dense and strong. In short: How strong and dense it is.
2. Hardness and Wear Resistance:
The "hard backbone" of cemented carbide comes from the tungsten carbide grains. Good sintering ensures these grains bond tightly, resulting in high overall blade hardness and wear resistance. Otherwise, it wears easily. In short: How durable it is.
3. Toughness (Chip Resistance):
The binder cobalt coats the tungsten carbide grains like "cement." The sintering process determines if the cobalt is evenly distributed and forms a complete layer. This directly affects whether the blade can withstand impact or chips easily upon collision. In short: How tough it is.
4. Dimensions and Shape:
The compact shrinks during sintering. A stable process allows for predictable shrinkage, producing blades with precise dimensions and minimal distortion. An unstable process causes dimensions to "drift," affecting clamping and use. In short: How accurate it is.
5. Surface Quality:
The vacuum environment prevents the blades from oxidizing or rusting at high temperatures. If the vacuum is insufficient or there's a leak, the blade surface can "develop mold" (oxidize or decarburize), forming soft spots or brittle layers, severely impacting its lifespan. In short: How clean the surface is.
