trimming
Used for appearance edge finishing and appearance closing; if you have high requirements for appearance edges, it is recommended to note "appearance surface/display surface".
Soft Rubber
Soft Rubber(typically PU/Rubber-Like TPU elastomers or rubber-like casting resins) is used in vacuum casting to produce flexible prototypes with "greater wear resistance/tear resistance/stronger rebound," suitable for soft-touch components and cushioning/protective parts requiring certain strength.
Quote checklist: Upload your 3D model and, when available, a 2D drawing. Identify the required process, material, quantity, critical dimensions, finish, appearance standard, and target delivery date.
Key Material and Manufacturing Parameters
Engineering note: Values below are typical reference ranges. Final manufacturability, tolerances, material condition, surface finish, cost, and lead time depend on the drawing, geometry, quantity, and selected process.
Upload CAD files and mark critical features for an engineering review before production.
| Process | Vacuum Casting |
|---|---|

| Applications | Suitable for scenarios such as prototypes and functional validation, you can choose a more suitable material solution based on appearance, strength, temperature resistance and cost targets. |
| Finishing | Trimming, removing edges, dyeing |
| Typical lead time | Relevant to structural complexity, quantity and finishing requirements; clear delivery and expedited options will be given after uploading the file. |
Finishing
Go to the front
Used to deal with marks such as edges and parting lines; it is recommended to mark parts that are sensitive to feel/appearance in drawings or notes.
Dyeing
To achieve target color or appearance consistency; please provide color number/reference image and indicate if batch consistency control is required.
Why choose soft glue (vacuum casting)
Flexible feel and appearance prototype
Suitable for prototypes that require "soft touch/flexible characteristics" for appearance review and experience verification.
Adaptation function verification
It can be used for functional validation prototypes; it is recommended to write down the stress mode and usage conditions in the remarks to facilitate more suitable solution suggestions.
Finishing controllable
Supports trimming, stripping and dyeing, making it easier to balance appearance and delivery pace.
Cost and performance balance
It is suitable for making a comprehensive trade-off between cost, appearance and performance; when the demand is more "hardcore", the materials can be upgraded or the process route can be adjusted.
Recommended Applications
- Appearance prototype: Requires flexible feel, appearance experience and rapid iteration
- Functional validation: Need to do basic functional validation and take into account costs
- Color/appearance controllable: Passable Dyeing Meet target appearance needs
It is not recommended to use it directly (it is recommended to change materials/processes)
- Performance indicators are very clear and stringent: When there are hard indicators for strength/temperature resistance/wear resistance, etc., it is recommended to upload working conditions and evaluate higher performance materials.
- Extremely standard appearance: When you are extremely sensitive to parting line/edge/surface consistency, please define the display surface and acceptance criteria in the remarks
- Extremely high size and assembly requirements: It is recommended to provide 2D annotation and do DFM review first
Design and DFM Guidelines
- Key dimensions and assembly locations: Please use 2D drawings to mark critical dimensions/tolerances and positioning datums to facilitate assessment of accuracy risks and machining allowances.
- Wall thickness and structural continuity: It is recommended to avoid sudden changes in thickness and reduce stress concentration through rounded corner transitions if necessary; the minimum wall thickness is referenced to 1.0mm.
- Appearance surface definition: Please define the surface that is sensitive to the edge/parting line as the display surface. We will give priority to removing the edge and trimming the edges.
- Color and Consistency: If you need to dye, please provide the color number/reference picture, and explain whether batch consistency control and usage environment (light/medium) are required.
- Functional validation working conditions: Please note the force mode, temperature range and medium environment (oil/water/solvent, etc.) in order to provide more suitable material and process suggestions.
