What is a custom mold?
A custom mold is not a one-size-fits-all tool—it’s engineered for your exact part design, production volume, and material.
A custom mold is a precision-engineered tool used to shape metal or plastic components. It’s built to exact specifications, usually with CNC machining, EDM, and grinding processes, and tailored to the customer’s geometry, alloy, and production needs.
Types of Custom Molds for Metal Parts
| Mold Type | Application | Material Commonly Used |
|---|---|---|
| Die Casting Mold | Aluminum, zinc parts | H13 or SKD61 tool steel |
| Metal Injection Mold | Small, detailed stainless parts | 420 SS or S7 tool steel |
| Stamping Die | Sheet metal components | D2 or SKD11 high-speed steel |
| Sand Casting Pattern | Prototypes, large iron parts | Aluminum, wood, or resin |
At Prime, we specialize in building custom molds using ISO-certified processes and customer-provided 3D models.

How to become a mold maker?
Mold making is a mix of mechanical skill, CAD/CAM design, and material science.
To become a mold maker, you need training in mechanical engineering, CAD software, and hands-on experience with CNC machines, EDM, polishing, and inspection tools. Apprenticeships and vocational schools are the usual path into this skilled trade.
Steps to Become a Mold Maker
- Study mechanical drawing and manufacturing basics
- Get formal training in CNC, mold assembly, and CAD/CAM
- Complete an apprenticeship or internship at a mold shop
- Learn materials like tool steels, aluminum, and coatings
- Develop attention to detail and problem-solving skills

At Prime, our lead mold designers have 15+ years of experience and are certified in both ISO 9001 and automotive PPAP requirements.
Are mold makers in demand?
In 2025, demand for mold makers is rising—especially in high-tech and industrial sectors.
Yes, mold makers are in high demand due to growing needs for precision parts in EVs, medical devices, automation, and aerospace. As older mold technicians retire, a new generation is urgently needed.
Industries That Rely on Mold Makers
| Industry | Type of Mold Required | Key Growth Driver |
|---|---|---|
| Automotive | Die casting, injection molds | EV and lightweight metal integration |
| Medical Devices | MIM, micro molds | Miniaturized instruments and implants |
| Aerospace | Investment molds, jigs | Titanium and high-temp metal shaping |
| Electronics | Insert molds, stamping dies | High-speed, automated assembly |

What is mold fabrication?
Mold fabrication isn’t just building a block—it’s precision manufacturing at every level.
Mold fabrication is the process of making the components that form a mold, including cores, cavities, base plates, guide systems, cooling lines, and ejector mechanisms. It involves CNC machining, EDM, grinding, polishing, and inspection.
Mold Fabrication Process at a Glance
- Receive CAD model and part spec
- Design mold with cooling, venting, and gating
- Machine base plates, cores, and cavity blocks
- Apply EDM for detailed and hardened features
- Assemble and test mold with sample shots
Prime uses CMM inspection, 5-axis machining, and mirror polishing for ultra-tight tolerances. Our average mold tolerance: ±0.01 mm.
