Outstanding Material
The metal mold cores of YunTai Company are carefully selected from high-quality alloy steel materials. This type of alloy steel incorporates a variety of rare metal elements and undergoes precise blending, achieving a perfect balance between ultra-high hardness and excellent toughness. For example, the addition of chromium significantly improves the wear resistance of the mold core, resulting in minimal surface wear even in working environments with frequent friction. Molybdenum endows the mold core with outstanding heat resistance, enabling it to maintain a stable internal structure without deformation or cracking even when subjected to the impact and pouring of high-temperature molten metal for long periods, fundamentally ensuring the long service life of the mold and its high-precision replication capabilities.
Exquisite Manufacturing Processes
1. Precision Forging: In the initial stage, advanced forging equipment is used to apply tens of thousands of tons of pressure to the raw materials, refining the internal metal grains and making their arrangement more compact, eliminating potential defects, and laying a solid foundation for subsequent processing. This ensures that the initial billets of the mold cores have a uniform texture and are free from flaws such as pores and sand holes.
2. CNC Machining: YunTai has invested in high-end five-axis linkage CNC milling machines. According to the well-designed 3D models, these machines precisely cut and carve every complex curved surface and fine structure, with dimensional tolerances that can be controlled within ±0.01mm. Even for high-precision mold cores like those for automobile engine blocks, they can be crafted with great precision.
3. Heat Treatment Optimization: Customized quenching and tempering processes are carried out, accurately controlling the heating rate, holding time, and cooling rate to fully tap the potential of the steel's properties. This allows the mold core to obtain an ideal hardness gradient, with a hard surface that resists wear and a flexible core that withstands impact, eliminating the risk of brittle fracture.
4. Surface Coating Treatment: Cutting-edge technologies such as physical vapor deposition (PVD) or electroless plating are used to apply a functional coating several micrometers to dozens of micrometers thick on the mold core. For example, a titanium nitride coating reduces the demolding resistance, enhances the corrosion resistance, and also improves the appearance of the mold.
Wide Range of Application Scenarios
1. Automobile Manufacturing Field: In processes such as automobile body stamping, die-casting of engine components, and forming of transmission housing, YunTai metal mold cores, with their high precision and durability, steadily produce tens of thousands of qualified parts that meet strict assembly standards, facilitating the efficient mass production of the automobile industry.
2. Consumer Electronics Industry: In the production processes of electronic products where extremely high requirements for dimensional accuracy and surface finish are imposed, from die-casting of mobile phone metal casings to the forming of notebook computer heat dissipation structures, the mold cores stably output casings and structural parts with a delicate texture and perfect fit, meeting the demands for stylish and thin designs.
3. Home Hardware Production: In the die-casting of hardware items such as faucets, door locks, and hinges, the mold cores withstand frequent mold opening and closing impacts. Relying on their robust materials and excellent craftsmanship, YunTai products maintain precise cavities over a long period, ensuring that the hardware items have uniform dimensions and high quality, suitable for large-scale home product assembly requirements.
Precautions for Use
1. Installation and Commissioning: During installation, professional tooling fixtures must be used to ensure that the mold core is accurately positioned in the mold base, and torque wrenches should be used to tighten the fixing bolts to the specified torque to prevent loosening. Before the initial mold closing, an appropriate amount of high-temperature lubricant should be applied, and the opening and closing actions should be tested 3 - 5 times to check for any interference or jamming.
2. Control of Operating Parameters: Based on the material and design specifications of the mold core, strictly limit the temperature, pressure, holding time, and other parameters during injection molding and die-casting. Do not operate under over-temperature or over-pressure conditions to avoid overloading and damaging the internal structure of the mold core. It is recommended to install real-time monitoring devices to accurately warn of abnormal working conditions.
3. Daily Maintenance: During the intervals between production batches, use professional mold cleaners to clean the residual materials in the mold cavity and then apply anti-rust agents. Regularly inspect the wear and corrosion conditions of the mold core's appearance, and repair and polish any minor damage in a timely manner. For long-term storage, it is necessary to seal the mold core in a dry and constant-temperature environment to prevent rusting due to moisture, which may affect the precision when it is put into use next time.
