Zeng Hsing’s international-standard mold manufacturing services in Vietnam were established to provide comprehensive solutions—from 3D design and CNC machining to end-to-end testing—helping businesses optimize costs and ensure absolute precision for every product.
The Current State and Trends of the Mold Manufacturing Industry in Vietnam
The mold and die manufacturing industry in Vietnam is currently one of the leading high-tech precision machinery industries, boasting an impressive growth rate averaging 18% per year, with a market size exceeding 1 billion USD. This industry serves as a foundation for key industrial sectors, including automotive, motorcycle, electronics, and home appliance manufacturing.

Current trends in the industry focus on
- Technological modernization: A shift from traditional mechanical machining to the use of CAD/CAM/CAE software systems and state-of-the-art CNC machines.
- Process specialization: A clear and in-depth separation between the stages of 3D design, rough machining, finish machining, mold inspection, and component assembly.
- Advanced technical innovations: Researching and applying complex technologies such as 3D cooling channel systems for molds to optimize plastic injection molding cycles.

Zeng Hsing’s International-Standard Mold Development Process
To transform complex engineering drawings into highly durable molds, Zeng Hsing operates a rigorous, end-to-end development process divided into two core segments:

Two-Plate Molds (For Simple Products)
- Features: Suitable for basic plastic component structures, optimizing production costs.
- Development time: 30 to 45 days.
- Capacity and specifications: Fully customizable based on specific customer requirements.
3-Layer Molds (For complex products)
- Features: Suitable for engineering plastic products with complex geometries, numerous hidden details, or requiring complex injection systems.
- Development time: 35 to 60 days.
- Capacity and specifications: Optimized design based on the characteristics of each type of plastic material.
All completed molds are seamlessly assembled by a team of skilled technicians. We conduct rigorous testing, calibration, and inspection of the molds right at our factory before delivery, ensuring they operate smoothly as soon as they are integrated into the mass production line.
State-of-the-Art Machinery and Technical Quality Management
What sets a Vietnamese mold manufacturing service that meets international standards apart is its equipment and error-control processes. At the Zeng Hsing factory, this capability is ensured by modern infrastructure:

Precision Mold Machining System
We own a system comprising 31 new-generation specialized machines, fully capable of handling all stages of blank manufacturing and mold cavity finishing:
- Machining Centers: We use high-precision CNC machines such as the Makino PS105/F5.
- Electrical Discharge Machining (EDM) Equipment: Includes 2 wire-cut EDM machines (WEDM-2) and 6 spark erosion machines (EDM).
- Support Equipment: Laser welding machines, surface grinders, and systems for technical turning, milling, and drilling.
- Advanced Surface Treatment: We perform surface sandblasting, manual polishing, or surface plating (either in-house or through outsourcing to reputable partners) to achieve the absolute smoothness and finish specified in the drawings.
Strict Quality Control Process
To completely eliminate the risk of parameter deviations, Zeng Hsing’s QA/QC department utilizes the most advanced measurement and inspection equipment:
- 1 3D scanner for reverse engineering.
- 1 2.5D measuring projector for geometric dimension inspection.
- 1 High-precision electronic height gauge.
- A system of calipers and other specialized digital measuring tools.
Practical Applications of Our Mold Manufacturing Services
Our services specialize in injection molds for common engineering plastics currently on the market, such as ABS, POM, PP, PC, etc., as well as specialized glass-fiber-reinforced plastic grades tailored to specific customer requirements.

- Dimensions and Capacity: Capable of manufacturing molds up to ~800 mm in size, perfectly compatible with plastic injection molding machines with clamping forces ranging from 75 metric tons to 650 metric tons.
- Typical Applications: Specializes in manufacturing molds for plastic components used in home appliances (washing machine housings, refrigerator parts, rice cookers) and office equipment (printer housings, paper trays), offering superior advantages in terms of short setup times and on-time delivery.
Why Choose Zeng Hsing’s Mold Manufacturing Services?
Among the multitude of mechanical machining companies in the market, Zeng Hsing has established its brand reputation and earned the trust of global partners based on three core values:
- Extensive experience: Building on over 50 years of foundational experience from an international conglomerate and more than 20 years of direct operations at our factory in the Vietnamese market.
- Transparency and Stability: All technical specifications, material origins, and process timelines are clearly reported to customers. Product quality remains absolutely consistent, whether producing thousands or millions of units.
- Convenient Strategic Location: The factory is located in the VSIP II-A Industrial Park, Binh Duong Province—the industrial hub of Southern Vietnam. This location helps optimize shipping times to neighboring industrial zones and expedite exports through the international port system.
Zeng Hsing is not merely a service provider; we are committed to serving as a strategic partner, working alongside our clients to foster sustainable growth within the supply chain.
