In the manufacturing process of household appliances like washing machines, the quality of the mold directly affects the precision, strength, and appearance of the shell. The mold base, as the "skeleton" of the mold, is the core component that determines the overall performance of the mold, particularly in terms of machining accuracy and stability. A professional mold base manufacturer must not only possess advanced equipment and technology but also have a deep understanding of the specific requirements of household appliance molds to provide customers with highly reliable solutions.
Core Value of Professional Mold Base Machining
The mold base (also known as the mold frame) serves as the foundational structure supporting and securing the core components of the mold, such as the mold core, sliders, and ejector pins. For large plastic products like washing machine shells, the mold structure is often complex and has a large forming area, placing extremely high demands on the rigidity, precision, and durability of the mold base.
Special Requirements for Mold Bases in Washing Machine Shell Molds
- Adaptation to Large Sizes: Washing machine shell molds typically fall into the medium-to-large category, requiring mold bases to have sufficient dimensional capacity, especially in the X and Y directions to accommodate the forming needs of wide panels.
- High Rigidity Support: The mold must withstand high pressure during the injection molding process, so the mold base must have excellent anti-deformation capabilities to ensure product dimensional stability and surface smoothness.
- Complex Cooling Systems: To improve the production efficiency and quality consistency of washing machine shells, mold bases often need to incorporate multi-channel deep-hole cooling systems, which poses challenges to the manufacturer's deep-hole drilling capabilities.
- Precise Guidance and Ejection: The guide pins and ejector systems of the mold base must be precisely aligned to ensure smooth mold opening and reliable demolding, preventing scratches or deformations on the shell.

Advanced Equipment Ensures Machining Capability
- Equipped with large gantry machining centers capable of maximum machining travel of X-axis 3500mm, Y-axis 2500mm, and Z-axis 1500mm, fully meeting the machining requirements for mold bases of large molds like washing machine shells.
- Multiple deep-hole drilling machines can process water holes up to 1450mm deep, ensuring the precision and reliability of complex cooling channels formed in a single process.
- A flexible production line consisting of 35 advanced CNC machining centers balances precision and efficiency, catering to various needs from small-batch customization to large-scale production.
Strict Quality Control Ensures Mold Base Precision
- Custom mold steel is selected for raw materials, offering high hardness and corrosion resistance. The material undergoes 90 days of natural stress relief before leaving the factory, followed by spectral and flaw detection testing to ensure material stability from the source.
- Full-process precision control, supported by a professional engineering team and precision measuring equipment, ensures that the flatness, hole position accuracy, and fit tolerances of the mold base meet high industry standards.
- Practical data show that the yield rate of products like washing machine shells produced by customers using Changhui's high-precision mold bases can exceed 99%.
Customized Services Tailored to Mold Requirements
- Optimize the mold base structure based on customer-provided 2D/3D mold drawings, such as adding reinforcement ribs in stress concentration areas or optimizing cooling channel layouts to extend mold life and improve production efficiency.
- Offer a variety of material options, including conventional S50C steel, pre-hardened steel, stainless steel, and other special materials to meet different molding conditions and longevity requirements.
- Possess large-scale delivery capabilities, with standard mold base lead times of 3–7 days and large custom mold bases delivered within 15 days. An expedited channel is also available for urgent needs.
