About Uniforce
The materials used to manufacture tools must have high high temperature hardness and wear resistance, Flexural strength, impact toughness and chemical inertia, good processability (cutting, forging and heat treatment, etc.), and not easy to deform. Generally, when the Hardness is high, the abrasion resistance is also high; When the Flexural strength is high, the impact toughness is also high. However, the higher the Hardness, the lower its Flexural strength and impact toughness. Because of its high Flexural strength, impact toughness and good machinability, high-speed steel is still a tool material widely used in modern times, followed by cemented carbide. Polycrystalline cubic Boron nitride is suitable for cutting hardened steel and hard cast iron with high hardness; Polycrystalline diamond is suitable for cutting non ferrous metals, alloys, plastics, and fiberglass; Carbon Tool steel and alloy Tool steel can only be used as files, dies, taps and other tools. The carbide indexable inserts have been coated with Titanium carbide, titanium nitride, aluminum oxide hard layer or composite hard layer by chemical vapor deposition. The developing vapor deposition method can not only be used for hard alloy cutting tools, but also for high-speed steel cutting tools, such as drills, hobs, taps, and milling cutters. Hard coatings act as barriers to chemical diffusion and heat conduction, slowing down the wear rate of cutting tools, and increasing the lifespan of coated blades by approximately 1-3 times compared to uncoated blades.

Vacuum Heat Treatment in Tool Forging
Vacuum heat treatment is a new type of heat treatment technology that combines vacuum technology and heat treatment technology. The vacuum environment in which vacuum heat treatment is located refers to the atmosphere environment below one atmospheric pressure, including low vacuum, medium vacuum, high vacuum, and ultra-high vacuum. Vacuum heat treatment is actually also an atmosphere controlled heat treatment. Vacuum heat treatment refers to the process where all or part of the heat treatment process is carried out in a vacuum state, greatly improving the quality of the heat treatment. Compared with conventional heat treatment, vacuum heat treatment can achieve no oxidation, decarburization, or carburization, remove phosphorus shavings from the surface of the workpiece, and have functions such as degreasing and degassing, thereby achieving the effect of surface brightness purification.

Chemical (or electrochemical) degreasing → Hot water washing → Flow water washing → Rust removal (10% sulfuric acid) → Flow water washing → Chemical polishing → Flow water washing → Neutralization → Flow water washing → Transfer to the next surface treatment process Working environment: The traditional polishing process has a harsh working environment, producing sand, iron filings, dust, etc. during the polishing process, which seriously pollutes the environment; Processing efficiency: manual polishing; Material consumption: Polishing requires the consumption of auxiliary materials such as polishing wheels, abrasives, and abrasive belts; Adaptability: Polishing can process simple surfaces such as flat surfaces, but cannot process curved surfaces. If processing complex surfaces such as R-arcs and surfaces.

The Process Principle of Vacuum Heat Treatment
(1) The phase transition characteristics of metals in a vacuum state. Under a vacuum with a pressure difference of only 0.1 MPa from atmospheric pressure, there is no change in the thermodynamics or kinetics of solid-state phase transitions. When formulating vacuum heat treatment process regulations, the principle of solid-state phase transformation under atmospheric pressure can be used. You can refer to data on various types of organizational transformations under atmospheric pressure. (2) Vacuum degassing improves the physical and mechanical properties of metal materials. (3) Vacuum degreasing effect. (4) Metal evaporation: When heated in a vacuum state, the surface elements of the workpiece will undergo evaporation. (5) The surface Catharsis can realize less oxidation and less decarburization heating. (6) The vacuum required for metal to achieve oxidation free heating.

What is the forging of kitchen knives?
The ancient craftsmanship of making knives, handmade, trades blood and sweat for quality. The swordsman hammered and forged the reddened steel blocks, opened them and folded them up to hammer, repeating this process dozens of times. The characteristic of forged knives is that they both have a blade support and a blade root. The blade support is the middle part connecting the blade and the blade handle, and the blade root is the part of the blade that blocks the blade. The integrated blade is an ideal forging tool, which means a truly seamless connection and tool holding method.

The main applications of vacuum heat treatment
After vacuum heat treatment, the parts have small distortion, high quality, and the process itself is flexible and pollution-free. Therefore, vacuum heat treatment is not only a means of heat treatment for certain special alloys, but also has been applied in the heat treatment of general engineering steel, especially tools, molds, and precision couplings. After vacuum heat treatment, the service life is greatly improved compared to general heat treatment. For example, some molds after vacuum heat treatment have a lifespan that is 40-400% higher than the original salt bath treatment, while many tools can have a lifespan that can be increased by about 3-4 times. In addition, the vacuum heating furnace can operate at higher temperatures and the workpiece can maintain a clean surface, thus accelerating the adsorption and reaction processes of chemical heat treatment. Therefore, certain chemical heat treatments, such as carburizing, nitriding, chromizing, boronizing, and multicomponent co infiltration, can achieve faster and better results.
