What is the best way to get started with your silicone production tool project?
The first step is to send us your part design and any relevant specifications. From there, we will work with you to finalize the tool design, material selection, and production schedule. If you’re unsure about any part of the process, our team is happy to guide you through the planning phase.
Tool material
We offer a wide range of hardened and semi-hardened tool steels. Among them, P20, NAK80, H13, and S136 are commonly used steels for silicone molding tools, each with distinct properties:
P20: Versatile, good toughness, used for general molds.
NAK80: High hardness, excellent finish quality, suitable for precision molds.
H13: Tough, heat-resistant steel, ideal for high-temperature applications.
S136: Corrosion-resistant, high hardness, often used for molds requiring durability and smooth finishes.
Which one is right for you?
Tool material selection on production volume, surface finish, product size and hardness, and structural complexity.
For low-volume production, materials like aluminum or soft steel are cost-effective but wear out quickly.
High-volume production requires hardened steels or alloys for durability and precision.
For high surface finish, high-precision steels are preferred. Larger or harder silicone products need stronger materials, and complex molds with intricate features require high-strength tool steels to ensure precision and longevity.
CNC Machining
We use CNC technology to create high-precision production tools. Our CNC capabilities include milling, turning, and EDM (Electrical Discharge Machining), ensuring tight tolerances and intricate features. Whether it’s for mold cavities, cores, or specialized tooling, our diverse CNC technologies guarantee reliable, high-quality results for your silicone products.
CNC Milling
CNC milling removes material using rotating tools to shape the workpiece. It’s ideal for creating complex, flat, or contoured surfaces and precise mold cavities. This process is versatile for both high-precision and large-volume production of silicone injection molds.
CNC Turning
CNC turning rotates the workpiece while a stationary cutting tool shapes it. This process is specifically suited for producing cylindrical or round parts, such as mold cores and inserts, ensuring high precision in features like diameters and lengths for silicone molding applications.
EDM
EDM uses electrical sparks to erode material, making it perfect for intricate, hard-to-machine features. This process is used to create fine details, deep cavities, and complex shapes, such as narrow grooves or sharp corners, in silicone molds that cannot be easily achieved with conventional machining.
Investment Advice
The investment cost and production efficiency of CNC milling, CNC turning, and EDM processes depend on the size, complexity, and material of the product. CNC milling and turning are generally more cost-effective for simpler, high-volume parts, with faster production times.
EDM, while more precise, requires a higher investment due to longer processing times and specialized equipment. The choice of material also affects costs—harder materials require more time and wear on tooling.
For accurate cost assessments and efficiency analysis, we recommend consulting with our engineers to evaluate the specific requirements of your product.
Rapid Tooling
Our rapid tooling service accelerates the creation of injection molds and parts, delivering high-quality results in a fraction of the time compared to traditional methods.
At NOCLON SILICONE, a dedicated machinist oversees your project from start to finish, ensuring precision and efficiency. By optimizing design, fabrication, and material selection, we reduce production time and costs. Using standard mold bases and P20 tool steel, we can produce molds in as little as 10 days.
This service is ideal for prototypes, product testing, and bridge production, allowing clients to test designs and limit financial risk before scaling to full production.
What is the difference with mass production tools?
Rapid tooling offers fast production with lower costs, but it has limitations in part complexity and material selection compared to mass production tooling. Key considerations include the simplified development process, which reduces lead time but may not accommodate highly intricate designs.
While mass production tooling is built for high volumes and can handle more intricate designs and materials, rapid tooling focuses on quicker lead times and cost efficiency, often used for prototypes or low-volume runs.
Despite this, we ensure the same high-quality standards through advanced equipment and testing, including positive material identification for full compliance. Additionally, we offer design-for-manufacturing (DFM) support and intelligent pricing with no minimum order requirements, providing value and efficiency for every project.
Tool design
When designing production tools, the key is to create a design that maximizes efficiency, precision, and durability. A good tool must allow for smooth, quick, and consistent production, while keeping the part’s dimensions stable over time.
The design should also minimize wear and tear, ensuring the tool can handle long production runs without losing performance. Essential factors like ease of maintenance, heat management, and material selection play a big role in achieving these goals.
To achieve this, we focus on creating precise, balanced designs. We carefully plan cooling channels to ensure even heat distribution and prevent thermal stress. We also select high-quality materials that can endure long production cycles.
Additionally, we test each tool rigorously to make sure it meets the required tolerances before it’s used in actual production. This attention to detail ensures that our tools not only produce high-quality parts but also perform consistently over time.
Toolmaking Tolerances
In the silicone industry, toolmaking tolerances vary depending on the specific application and manufacturing process. Below is a summary of typical tolerance guidelines:
| Dimension Type | Tolerance Range | Notes |
|---|---|---|
| Linear Dimensions | ±0.05 mm to ±0.2 mm | Depending on the size and complexity of the mold design. |
| Wall Thickness | ±0.1 mm to ±0.2 mm | Commonly applied for consistent silicone product thickness. |
| Hole Diameter | ±0.05 mm to ±0.1 mm | Ensures precision for functional or assembly-related holes. |
| Shrinkage Allowance | 1% to 3% | Compensation for silicone shrinkage during curing, adjusted based on material properties. |
| Surface Finish | Ra 0.8 μm or better | Depending on the functional or aesthetic requirements of the final product. |
Additional Notes:
- Standard Tolerances: NOCLON SILICONE typically adheres to DIN 2768-1-fine for toolmaking, ensuring high precision and reliability.
