CNC Machining Tolerances

Maximum Part Size

Maximum Volume

Standard Accuracy

Wall Thickness

Shrinkage

Surface Appearance

Color Options

Maximum part dimension up to 1900 × 900 × 750mm.

Maximum volume up to 10L.

The accuracy is usually within ±0.3mm for dimensions smaller than 100mm.

The wall thickness should not be too thin or too thick. Thin walls may cause deformation, while thick walls may cause shrinkage. The recommended wall thickness is at least 1.5mm.

0.1mm-0.2mm shrinkage may not be completely prevented during the process.

Vacuum casting parts feature high-quality appearance and smooth surfaces.

Custom colors can be achieved by adding pigments into the liquid material.

Advantages and Challenges of Vacuum Casting

Vacuum casting is an efficient manufacturing process for producing prototypes and low-volume plastic parts. Compared with CNC machining and injection molding, vacuum casting provides shorter lead time, lower production costs, and more material options for small batch manufacturing. The process can produce parts with excellent appearance, high repeatability, and precise tolerances, making it suitable for prototype verification and low-volume production.

CNC Machining FAQ

What is vacuum casting?

Vacuum casting is a forming technology for making plastic parts in low quantities. The process uses a master model produced by CNC machining or 3D printing to create a silicone mold, then plastic liquid is poured into the mold to form the final parts.

What are the advantages of vacuum casting?

The main advantages of vacuum casting include shorter lead time, lower cost, more plastic material options, excellent appearance, precise tolerance, and high-quality finished parts.

What materials can be used for vacuum casting?

BOEN supports various vacuum casting materials including ABS, PC, PMMA, PP, PE, HDPE, Rubber, PA, and other engineering plastic materials.

What is the typical accuracy of vacuum casting parts?

The accuracy of vacuum casting is usually within ±0.3mm for dimensions smaller than 100mm.

What is the maximum size of vacuum casting parts?

The maximum part dimension is 1900 × 900 × 750mm, and the maximum volume is 10L.

Do you support custom vacuum casting parts?

Yes. BOEN provides customized vacuum casting services according to customer drawings, 3D files, and project requirements.

How do you ensure vacuum casting quality?

BOEN uses an ISO 9001:2015-certified quality management system and controls every step of the production process to ensure consistent quality.

How can I get a quote for vacuum casting?

Send your drawings, 3D files, or project details. BOEN engineers will review your requirements and provide suitable manufacturing solutions and quotations.
