Our precision mold machining services go beyond simply owning state-of-the-art equipment such as wire cut machines or EDM machines; they also rely on a team of skilled and dedicated technicians. By choosing Zeng Hsing, you are choosing a lasting commitment to quality, on-time delivery, and long-term cost-effectiveness.
What is precision mold machining?
Precision mold machining is the process of manufacturing various types of molds (plastic molds, stamping dies, casting molds) using high-tech machinery such as CNC, EDM, and wire cutting. At Zeng Hsing, we achieve extremely high precision with tolerances ranging from ±0.002mm to ±0.005mm, ensuring that plastic or metal products emerging from the mold are absolutely uniform.

Comparison Table of Two-Plate and Three-Plate Molds at Zeng Hsin
| Criteria | 2-Plate Mold | 3-Plate Mold |
| Product Complexity | Suitable for simple products with minimal undercuts or complex features. |
Designed for complex products requiring multiple injection gate locations. |
| Mold Structure | Features a single parting line. |
Incorporates two parting lines—one for the molded part and one for the runner system. |
| Gate Location | Typically positioned at the edge of the product (edge gate). |
Can be positioned at the center or virtually any location on the product surface. |
| Automatic Runner Separation | Runner must be removed manually or by a trimming robot after molding. |
Automatically separates the runner from the product when the mold opens. |
| Development Time at ZH | 30–45 days. | 35–60 days. |
| Manufacturing Cost | Lower cost due to a simpler design and easier maintenance. |
Higher cost because of its more complex structure and additional mold components |
Key Advantages of Each Type at Zeng Hsing
Two-Plate Mold (The Optimal Cost-Effective Choice)
- Stable Operation: Due to its simple structure, the 2-layer mold at ZH features fast injection molding cycles and fewer technical issues during mass production.
- Cost-Effective: Short design and machining times allow businesses to quickly bring simple products to market with low investment.
- Easy Maintenance: The guide and cooling systems are easy to clean, helping to extend the mold’s service life without requiring overly complex technical procedures.
3-Layer Mold (A Solution for High-Quality Products)
- Excellent Aesthetics: Thanks to the ability to place the injection gate (Pinpoint gate) directly on the surface, the 3-layer mold minimizes gate marks, making it ideal for the housings of household and office appliances.
- High Automation Efficiency: The automatic sprue-trimming mechanism allows the injection molding machine to operate continuously without manual intervention, reducing labor costs and preventing product deformation during sprue removal.
- Optimal Flow Control: For large products or those requiring high precision, the 3-layer mold ensures even distribution of plastic flow throughout the mold cavity, minimizing warping or material short-shot issues.
