We offer a wide range of additional alloys and tempers upon request, sourced to meet your specific mould requirements. If your desired alloy or material is not listed on our platform, simply select "Other" and specify the material.
For custom CNC milled parts, including both metal and plastic options, we provide instant online quotes. If the material stock you need is not available, choose "Other" under the material drop-down menu on the quote page. Submit your request for an expert engineering review by specifying features, tolerances, inspection needs, and quantities required. Our services ensure that your mold production meets the highest standards of quality and precision.
CNC Milling Tolerances
At Lsrmold, we provide a comprehensive range of CNC machining tolerances tailored to your specific design needs, including GD&T callouts. Depending on your mold’s geometry and material selection, we can handle standard thread sizes, create custom threads, and achieve tolerances as precise as ±0.001”. For CNC milled metals, our standard tolerances adhere to ISO 2768-m, while for plastics, we follow ISO 2768-c.
| Description | General Tolerance or Standard |
| Maximum Part Size | Milled parts up to 80” x 48” x 24” (2,032 x 1,219 x 610 mm). |
| Distance Dimensions | For features of size (Length, width, height, diameter) and location (position, concentricity, symmetry) +/- 0.005”. |
| Orientation and Form Dimensions | 0-12″ +/- 0.005″, Angularity 1/2 degree. For 24″ and beyond please consult RJCmold’s Manufacturing Standards. |
| Precision Tolerances | RJCmold can manufacture and inspect to tight tolerances per your drawing specifications including GD&T callouts. |
| Minimum Feature Size | 0.020” (0.50 mm). This may vary depending on part geometry and chosen material. |
| Threads and Tapped Holes | RJCmold can accommodate any standard thread size. We can also machine custom threads; these will require a manual quote review. |
| Surface Finish | The standard finish is as-machined: 125 Ra or better. Additional finishing options can be specified when getting a quote. |
| Edge Condition | Sharp edges will be broken and deburred by default. Critical edges that must be left sharp should be noted and specified on a print. |
Surface Finishes for CNC Milling
Enhance the aesthetic and functional qualities of your custom CNC-milled molds with our premium surface finishing options. These finishes not only address visual imperfections but also add rigidity, protection, and increased durability to your molds.
Anodizing
Anodizing enhances corrosion resistance, increases wear resistance and hardness, and protects metal surfaces. Commonly applied to mechanical parts, aerospace components, and automotive parts.
Materials: Aluminum.
Bead Blasting
Bead blasting provides a smooth, matte finish suitable for visual applications. This process is often used as a preliminary step before additional surface treatments.
Materials: ABS, Aluminum, Brass, Stainless Steel, Steel.
Powder Coating
Powder coating offers a robust finish applied as a free-flowing, dry powder. Unlike traditional liquid paints, it is electrostatically applied and then cured with heat or UV light, providing a durable and consistent coating.
Materials: Aluminum, Stainless Steel, Steel.
Electroplating
Electroplating can serve functional, decorative, or corrosion-resistant purposes. This process is frequently utilized in industries like automotive, where chrome-plating is common for steel components.
Materials: Aluminum, Steel, Stainless Steel.
Polishing
Polishing achieves a high-gloss finish either through physical rubbing or chemical processes, resulting in a smooth surface with significant reflectivity, while reducing diffuse reflection in some materials.
Materials: Aluminum, Brass, Stainless Steel, Steel.
Brushing
Brushing involves using abrasive belts to create distinct surface textures, often for aesthetic purposes.
Materials: ABS, Aluminum, Brass, Stainless Steel, Steel.
