Introduction: Solving Industry Pain Points
The global demand for high-quality, custom phone cases is rising, but phone case manufacturers face persistent challenges:
Low mold precision is causing uneven edges and color inconsistencies.
Slow production cycles due to outdated equipment.
Limited capability to produce ultra-thin or multi-material designs.
At YG, a leading Phone Case Factory, we’ve invested in 14 advanced machines (including Sumitomo SE-EV-S, Haitian MA series, and Makino EDGE3i/U3) to eliminate these issues. Our upgrade ensures high-precision injection molding, faster lead times, and eco-friendly operations for US and European clients.
New Equipment Breakdown: Technical Edge & Competitive Advantages
1. Sumitomo SE-EV-S All-Electric Injection Molding Machines
Technical Specs:
Lock Force: 500–1,800 kN (model-dependent).
Clamping Speed: Up to 1,000 mm/s for ultra-thin cases.
Energy Efficiency: 50% lower power consumption vs. hydraulic machines.
Performance Highlights:
Flow Front Control (FFC): Reduces injection pressure by 30%, eliminating flash and short shots in multi-cavity molds (e.g., iPhone 15 cases).
Zero-Molding Technology: Minimizes clamping force to protect delicate molds while ensuring perfect cavity balance.
Medical-Grade Precision: Achieves ±0.01mm repeatability, ideal for 0.3 mm-thick silicone cases with zero burrs.
Vs. Competitors:
Traditional hydraulic machines struggle with ±0.05mm accuracy and 15% longer cycle times.
2. Haitian MA Series Injection Molding Machines
Technical Specs:
Lock Force: 160T (12 units) & 200T (2 units).
Injection Speed: ≥120 cm³/s (MA1600) and 210 MPa pressure (MA2000).
Performance Highlights:
High-Speed Molding: 15% shorter cycles (8,000 cases/day vs. 7,000 industry average).
Enhanced Stability: Dual-axis nozzle support prevents template tilting, reducing warpage in tablet cases8.
Energy Savings: 30% lower energy use with optimized servo motors.
Client Case: A European brand reduced defect rates from 5% to 0.8% for anti-yellowing TPU cases.
3. Makino EDGE3i Sinker EDM
Technical Specs:
Accuracy: ±2μm for micro-hole machining (e.g., AirPod case vents)
ATC System: 8-tool capacity enables unattended operation overnight
Surface Finish: Ra ≤0.2μm using SuperSpark IV technology
Performance Highlights:
4-Sided Access: Programmable work tank simplifies electrode changes, cutting setup time by 40%
Thermal Stability: Integrated dielectric reservoir prevents distortion in large molds
Vs. Conventional EDM: Older models average Ra ≥0.5μm and require manual tool changes.
4. Makino U3 5-Axis CNC Machines
Technical Specs:
Spindle Speed: 20,000 RPM for mirror-finish molds.
Positioning Accuracy: ±1.5μm for 3D Surface texture.
Performance Highlights:
Complex Geometry: Machines snap-fit structures and logo designs in one setup.
Tool Life: 30% longer lifespan with adaptive cooling, reducing mold-making costs.
Client Case: A U.S. client achieved 98% dimensional accuracy for MagSafe-compatible cases.
Integrated Benefits for Global Clients
Faster Turnaround: 72-hour prototyping (vs. 5–7 days industry standard).
Superior Quality:
Color Consistency: 35% better pigment dispersion with SL screw.
Drop Test Compliance: Cases withstand 1.5m drops (surpassing 1.2m norms).
Sustainability: 30% lower energy use across production lines.
Certifications & Success Stories
ISO 13485 (Medical-Grade Molding)& ISO 14001 (Environmental management system)
Case Study: A German brand reduced the delivery cycle by 25% for biodegradable PLA cases.
Conclusion
YG’s cutting-edge mold-making machines and high-precision injection molding capabilities ensure your phone cases stand out in durability, design, and eco-friendliness.
