What is Plastic Injection Mold Manufacturing?
Injection Mold Manufacturing is a specialized process for creating precision metal molds. Using these customized “steel stamps,” your plastic products (such as phone cases, medical parts, or automotive components) can be mass-produced on injection molding machines at high speed, low cost, and with zero error.
Why should you care about injection mold manufacturing? A high-quality injection mold can produce over one million parts at a cost as low as $0.02 per piece (at mass production), significantly lower than 3D printing or CNC machining. In essence, investing in superior injection mold manufacturing builds a reliable, scalable foundation for your product’s mass production success.

Workflow of Injection Mold Making
Creating an injection mold involves a structured process to ensure precision and reliability. Here’s how it typically works:
1. Product Analysis & Design Review
Our team at YG starts by reviewing your product design (3D/2D drawings or samples). We check details like wall thickness, undercuts, and material needs to confirm if injection molding is suitable. If design tweaks would make manufacturing smoother, we’ll discuss adjustments with you.
2. Mold Design & Material Planning
Using tools like SolidWorks or UG, YG’s engineers design the full mold structure—including parting lines, gating systems, cooling channels, and ejection mechanisms. We also select mold materials (e.g., S136, 718H) based on your product’s needs and source them promptly.
3. Precision Component Machining
All mold parts are machined at YG with strict precision: Rough shaping to remove excess material. Heat treatment to harden steel. Fine machining (via CNC, EDM, grinding) for exact dimensions and surface quality. Final polishing for smooth finishes.
4. Mold Assembly
Our technicians assemble all machined parts into a complete mold. We ensure tight fits: guide pins slide smoothly, ejection systems work without jamming, and mold halves seal properly to prevent excess plastic (flash).
5.Trial Runs & Refinement
The mold is tested on our injection machines: Initial trials (T1, T2) to check for defects like incomplete filling or warping. Adjustments to the mold or processing settings and small-batch tests until parts match your standards.
6. Mass Production & Delivery
Once the mold passes all tests, YG proceeds to large-scale production. We provide you with inspection reports and maintenance guidelines to support long-term use of the mold.

Advanced Mold Manufacturing Techniques
Precision, consistency, and aesthetics directly impact product success. YG leverages advanced injection mold manufacturing technologies to address the specific challenges of producing miniature, complex, and high-quality components.
CNC Precision Machining
Multi-axis CNC machines process a variety of complex mold parts through high-speed milling, turning, drilling, and precision grinding.
- 5 Mikron CNC + 3 Makino CNC + 4 FANUC CNC
- High-speed milling of various steels, 718H, H13, T10A, etc.
- ±0.001mm tight tolerances
EDM (Electrical Discharge Machining)
Complex cavities and shapes can be created in hard metals by eroding the material using a controlled electrical discharge between the electrode and the workpiece.
- Mirror EDM equipment: 2 Charmilles, 7 Makino
- Electrode wear rate below 0.01mm/hour
- Cutting die steel (HRC＞60), the cutting edge shape remains intact
WEDM (Wire Electrical Discharge Machining)
Features a thin metal wire as the electrode, which moves along a programmed path to cut through the workpiece via electrical discharges.
- 6 wire EDM machines (Makino*3)
- Cutting tolerance controlled within ±0.001mm
- Wire electrode diameter as small as 0.1mm
Fine Surface Finishing
Involves processes like polishing, buffing, and chemical treatment to refine the mold surface, this improves product release and extends mold service life.
- Ra≤0.02μm mirror finish (SPI-A1)
- VDI 3400/VDA compliant custom textures
- DLC/TiN coatings: 30%+ wear resistance
