Application Fields
Metal Powder Molding
Widely used in producing precision metal parts for automobiles, aerospace, and electronics. It manufactures parts with complex shapes, improves material utilization, and reduces production costs.
Ceramic Powder Molding
Enables ceramic powder to be uniformly compacted in specific molds and sintered at high temperatures to form various industrial products, such as electronic insulators and biomedical artificial bones.
Magnetic Core Molding
Presses soft magnetic material powder into magnetic cores with high density and excellent magnetic properties, crucial for producing power supplies and communication equipment.
Working Principle
1. Feeding
Powder materials are uniformly added into the mold of the molding machine, ensuring consistency and proper looseness of the powder.
2. Pressing
Controlled pressure is applied to shape the powder under mold constraints. Pressure magnitude, speed, and holding time significantly impact product performance.
3. Demolding
After pressing, the molded product is carefully ejected from the mold, ensuring it remains intact and free of cracks or deformation.
Key Technologies & Features
- High Precision: Achieves precise control over product dimensions, ensuring uniform density, high accuracy, and excellent stability.
- Strong Adaptability: Perfectly suited for irregular shapes and ultra-small product molding, preventing overfilling, ensuring stable filling, and eliminating powder leakage.
- Energy Saving & Environmental Protection: The servo system features convenient speed adjustments and silent transmission, delivering significant energy savings (averaging more than one fold).
- Simple Maintenance: Simplified servo abnormality troubleshooting, making daily maintenance, operation, and mold replacement highly convenient.
- Mold Design Technology: As a core component, the mold design factors in powder material characteristics, product shape, dimensions, and the pressing process to ensure high-efficiency, high-precision results.
