Common mold types manufactured at our facility

     Our production capacity covers diverse tooling types across multiple industries, highlighted by plastic injection molds and aluminum die casting molds.

Plastic injection molds (2-plate and 3-plate systems)

     Plastic injection tooling represents a primary strength within our mold manufacturing in HCMC service portfolio:

          • 2-plate molds: Typically applied to parts with relatively straightforward geometries using edge gates or sub-gates. The lead time for this tooling style ranges between 30 and 45 days, minimizing upfront capital investment for clients.

          • 3-plate molds: Designed for intricate geometries requiring multiple pinpoint gates placed directly on the part surface for balanced melt flow distribution. Lead times for 3-plate molds generally range from 35 to 60 days depending on slider mechanism complexity.

     Our facilities can machine molds for plastic components up to approximately 800 mm in size, compatible with injection molding machines rated from 75 tons to 650 tons. We process a wide range of engineering polymers, including ABS, POM, PP, PC, PMMA, and PC/ABS alloys.

High-pressure aluminum die casting molds

     Beyond plastics, our mold manufacturing in HCMC serves clients in the high-pressure aluminum die casting sector. Tooling cavities are fabricated from heat-resistant, wear-resistant tool steels, ensuring structural integrity under high melt temperatures and intense injection pressures:

          • Fully compatible with standard casting alloys JIS ADC12, A380.1, AC4400, AC4700, and more.

          • Optimized cooling lines and venting systems to minimize internal porosity in cast components.

          • Consistent cavity durability, maintaining sharp part dimensions across prolonged production cycles.

Machinery fleet supporting high-precision mold manufacturing in HCMC

     The precision of each mold component heavily depends on the manufacturing machinery utilized. Zeng Hsing utilizes advanced machining centers to execute mechanical blueprints with minimal tolerances.

Modern mechanical machining fleet

     Roughing and core/cavity detailing are performed using specialized equipment:

          – CNC milling centers: Highlighted by high-end CNC lines such as the Makino PS105 and Makino F5, ensuring high-speed cutting, smooth surface finishes, and strict dimensional tolerances.

          – Electrical discharge machining (EDM) & wire EDM (WEDM): The floor operates 6 sinker EDM machines and 2 WEDM wire-cutting units to machine deep ribs, sharp internal radii, keyways, or intricate patterns inaccessible to rotary cutters.

          – Auxiliary toolroom machinery: Precision surface grinders, laser welders, lathes, and radial arm drills supporting the fitting and finishing of every mold base component.

Dimensional metrology and surface treatment equipment

     Following roughing and finishing passes, mold components proceed through post-processing and quality inspection:

          – Versatile surface finishing: Texturing via sandblasting, meticulous hand polishing, or chemical grain etching per client aesthetic specifications.

          – Quality metrology instruments: The QC department uses 3D laser scanners, 2.5D optical profile projectors, and digital height gauges to cross-check physical measurements against CAD files, ensuring tools pass engineering specifications before release.

     Thanks to structured machinery investments, projects involving mold manufacturing in HCMC handled by our team maintain high repeatability and durability.

How is the cost of mold manufacturing in HCMC calculated?

Factors directly impacting mold pricing

     Tooling costs are a critical consideration for any manufacturing enterprise. Pricing for mold manufacturing in HCMC is not fixed; it depends on several core technical variables:

          • Mold size and mechanical structure: Larger components require thicker steel mold plates. In addition, molds featuring multiple side-actions, angled lifters, hydraulic core-pull cylinders, or multi-plate mechanisms carry higher costs than standard 2-plate molds.

          • Tool steel grades: Depending on the project's expected production lifespan, clients can choose pre-hardened steels (S50C, P20) for medium runs, or premium through-hardened tool steels (NAK80, SKD61, H13) that undergo heat treatment for superior wear resistance in high-volume production.

          • Cavitation count: Single-cavity tools carry lower initial fabrication costs, making them ideal for market testing. In contrast, multi-cavity molds require higher initial capital investment but significantly reduce individual cycle costs during mass production.

          • Cavity surface finishing requirements: Parts requiring optical-grade mirror finishes or complex EDM grain textures demand extended benchwork hours, directly affecting overall project estimates.

Transparent intake and quotation process at Zeng Hsing

     At Zeng Hsing, quotations for mold manufacturing in HCMC follow a transparent process:

          1. Receiving 2D/3D CAD models (STEP, IGS, XT formats) or physical samples from the customer.

          2. Conducting Design for Manufacturability (DFM) analyses to advise on cost-efficient mold architectures.

          3. Providing a comprehensive, itemized quotation detailing tool steel costs, machining time, sampling trial schedules, and committed delivery dates.

     Enterprises retain full budgetary control when collaborating with a tooling partner with structured workflows like Zeng Hsing.

Quality commitments and value delivered to clients

     Selecting the right partner for mold manufacturing in HCMC helps enterprises reduce project delays and avoid mold breakdowns during mass production. We deliver clear technical benefits:

Guaranteed adherence to engineering drawings

     Every machining pass is supervised by experienced tooling specialists. Once finished, mold cavities are spotted on die-spotting presses to verify tight parting-line shutoffs, preventing flashing during plastic molding or aluminum casting. Combining Makino CNC centers with 2.5D optical systems and 3D scanners allows us to maintain strict tolerances across all mold manufacturing in HCMC deliverables.

Stable tool life and long-term technical support

     We use genuine steel grades certified according to client agreements, paired with standardized heat treatment to achieve uniform core hardness. Post-delivery, our technical team remains available to support injection molding parameter optimization, preventative maintenance, and troubleshooting throughout the tool's operating lifespan.

Cost optimization and schedule control

     The entire lifecycle—from CAD/CAM design and CNC machining to assembly and mold trials—is executed in-house. By eliminating intermediary processing markups, our mold manufacturing in HCMC services optimize costs while allowing clients to monitor production milestones closely. When minor design revisions arise during pilot sampling, our engineers carry out modifications directly on-site with minimal turnaround times.
