1. Working Principle of Tungsten Carbide Mold
 
Tungsten carbide molds mainly rely on their high hardness, high strength and excellent wear resistance to achieve the forming and processing of materials. During operation, the alloy materials to be processed are placed in the mold cavity. External pressure (such as the powerful pressure provided by hydraulic presses and other equipment) is applied to force the alloy materials to undergo plastic deformation according to the shape of the mold cavity, so that they are pressed into the required shapes. For example, when manufacturing small precision alloy parts, the pretreated alloy raw materials are put into a specially made tungsten carbide mold. When the press is started and pressure acts on the alloy, the alloy will gradually fill every corner of the mold cavity and finally form parts that meet the design requirements.

3. Occasions for Applying Tungsten Carbide Mold
 
They are widely used in the aerospace field. For example, some superalloy parts in aircraft engines often have extremely high precision requirements and complex shapes, and need to work reliably under extreme conditions such as high temperature and high pressure. By using tungsten carbide molds, superalloy materials can be accurately pressed into the required complex shapes to meet the high-performance requirements of aircraft engines. Because the high precision and high strength of tungsten carbide molds can ensure that when processing these high-requirement alloy parts, the dimensional errors can be controlled within a very small range and enable them to withstand the subsequent harsh working environments.
 
4. Process of Making Alloys with Tungsten Carbide Mold
 
(1) Raw Material Preparation: First, select appropriate alloy raw materials. According to the composition requirements of the alloy products to be manufactured, accurately weigh various metal elements, and then mix them evenly through melting and other methods to make billets with certain shapes (such as blocks, columns, etc.). And carry out necessary pretreatment on the billets, such as removing surface impurities and oxides, to ensure the purity and quality of the billets.
(2) Mold Installation and Commissioning: Install the tungsten carbide molds on the corresponding press equipment, carefully check whether the molds are firmly installed and whether the cooperation between various components is close, and conduct commissioning at the same time to ensure that when the press applies pressure, the molds can open and close normally and the pressure is evenly transmitted, avoiding problems such as uneven pressure leading to product forming defects.
(3) Loading and Pressing: Place the prepared alloy billets inside the mold cavity, start the press, and slowly apply pressure according to the preset pressure parameters, so that the alloy billets gradually undergo plastic deformation in the mold cavity until they fill the entire cavity and meet the required density and dimensional requirements. During this process, pay close attention to the change in pressure and the state of product forming, and make adjustments in a timely manner.
(4) Demolding and Post-treatment: After the pressing process is completed, carefully remove the formed alloy products from the molds. Some auxiliary demolding tools or measures can be adopted to prevent damage to the products during the demolding process. The demolded products may still need subsequent processing, such as surface grinding and heat treatment, to further improve the performance and surface quality of the products and finally obtain alloy products that meet the requirements.
