CNC steel molds for silicone production
The foundation of any successful silicone product is the mold-making expertise that goes into it. At Dabojin, CNC mold machining is the critical step after design, forming one link in the chain of processes we use to create custom silicone components from concept to production. We choose the right mold material, usually steel, based on budget and required production quantity. Our engineering knowledge maximizes the return on the mold investment by focusing on key factors that ensure product quality and efficient manufacturing, including:
- ✓Precision and Tolerance: Maintaining tight tolerance, correctly calculating material shrinkage rate, and designing the ideal flash lines.
- ✓Material and Process: Planning for temperature control and selecting the right process, whether it's standard compression molding, complex 2-shot molding, or overmolding.
- ✓Finish: Polishing the mold surface to achieve the required finish.
We handle everything, including secure mold storage and keeping your design confidential.
Designing product is an art that establishes the ideal form and function, while turning that design into a mold is the engineering process that applies mathematical principles to ensure its manufacturability, durability, and cost-effectiveness.
Which Mold Material Fits Your Project?
We select the mold material based on your production needs.
Steel (carbon, stainless)
Long-lasting, ideal for high-volume production. The go-to for durability.
Aluminum
Lightweight, fast to machine, excellent for smaller batches. The perfect choice for prototypes.
Brass, Copper, Bronze
Superior heat transfer for controlled curing. Best for applications needing precise temperature control.
Titanium
Strength + corrosion resistance. High-performance material for demanding environments.
Cast Iron
Stable choice for heavy-duty, large molds. A reliable foundation for big projects.
Specialty Alloys
Used for extreme environments requiring high heat or corrosion resistance.
| Specification | Representative Name | Hardness (HRC) | Notes |
|---|---|---|---|
| Quenched/Tempered (Non-Sintered) | STAVAX | 33 | Stainless steel, durable |
| PSL35 | 35 | Stainless, good machinability | |
| NAK55 | 40 | High polishability | |
| Sintered (Tempered Steel) | STAVAX | 52 | Wear-resistant |
| ELMAX | 57 | Premium stainless, high hardness | |
| PD613 | 60 | Tool steel for long life | |
| SC (Carbon Steel) | S50C | 13 | Prone to rust, for basic molds |
| Stainless (SUS) | RAMAX | 33 | Corrosion resistant, higher cost |
