Custom Vacuum Casting Services for Prototypes & Low-Volume Production
Turn your CAD designs into detailed polyurethane parts with silicone mold vacuum casting. Senses Mold supports functional prototypes, appearance models and low-volume production with material selection, finishing and engineering review.
What Is Vacuum Casting?
Vacuum casting is a manufacturing process used to reproduce a master pattern in a silicone mold, commonly with polyurethane (PU) resin. After the mold is prepared, liquid casting material is introduced under controlled vacuum conditions to help reduce trapped air and capture fine details. The material cures and the finished part is removed from the flexible mold.
Also called urethane casting or silicone mold casting in many prototyping contexts, this method is useful for creating realistic housings, covers, grips and engineering samples without investing in a hardened steel injection mold.
For clarity, the service described here is polyurethane vacuum casting, not vacuum-assisted metal die casting.

How Does the Vacuum Casting Process Work?
The vacuum casting process creates production-like parts from a master pattern by making a silicone mold and casting polyurethane resin under vacuum. After curing, the parts are demolded, finished, and inspected before delivery.
3D CAD → Master Pattern
We start from your 3D CAD data and create a master pattern using SLA 3D printing or CNC machining, depending on the required accuracy, surface quality, and geometry.
Master Pattern → Silicone Mold
The master pattern is enclosed in liquid silicone to create a flexible mold cavity. Parting lines, gates, and vents are considered according to the part geometry.
Mold Preparation
The silicone mold is opened, cleaned, positioned, and checked before casting to support proper filling and accurate detail reproduction.
Polyurethane Casting Under Vacuum
The selected polyurethane casting resin or urethane resin is mixed and poured into the silicone mold under vacuum. This helps reduce trapped air and reproduce complex geometry and surface details.
Demolding & Finishing
After curing, the part is removed from the silicone mold. Gates, flash, and excess material are trimmed, followed by any required surface finishing or secondary operations.
Inspection & Delivery
Finished vacuum cast parts are checked for dimensions, appearance, surface quality, and project-specific functional requirements before delivery.
What Controls Vacuum Casting Part Quality?
Consistent vacuum cast parts depend on the master pattern, silicone mold design, material selection, and casting control — not only the casting stage itself.
Master Pattern Accuracy
The master pattern establishes the dimensional and surface reference for the silicone mold.
Silicone Mold Design
Parting lines, gates, vents, and mold construction affect detail reproduction and filling performance.
Casting Control
Mixing, vacuum conditions, curing, demolding, and finishing influence consistency and appearance.

Vacuum Casting Design Guidelines
A good CAD model reduces tooling revisions, cosmetic defects and unnecessary rework. The recommendations below are review topics rather than universal manufacturing limits.
| Design Factor | What to Consider | Recommended RFQ Information |
|---|---|---|
| Wall Thickness | Keep walls reasonably uniform where possible; thick sections may affect curing and shrinkage. | Minimum and maximum wall thickness |
| Undercuts | Flexible silicone molds can accommodate certain undercuts, subject to geometry and mold life. | 3D CAD and critical feature locations |
| Draft & Demolding | Draft is often less restrictive than in metal tooling, but release strategy still matters. | Appearance surfaces and parting-line preferences |
| Holes & Fine Details | Very small holes, thin ribs and delicate details need engineering review. | Critical dimensions and tolerance callouts |
| Dimensional Accuracy | Resin shrinkage, mold condition and part geometry affect achievable tolerances. | 2D drawing with inspection-critical dimensions |
| Mold Life | Silicone molds wear over repeated cycles; mold count may increase with order quantity. | Target order quantity and repeat-order forecast |
| Surface Finish | The master pattern strongly influences cast surface quality. | Cosmetic standard, texture reference or approved sample |

Send us your 3D CAD file, target quantity, material requirements, and application. Our engineers can review your requirements and recommend whether vacuum casting is a suitable manufacturing option.
How Much Does Vacuum Casting Cost?
Vacuum casting cost depends on both one-time mold preparation and the cost of each cast component. A meaningful quote requires part geometry, material and order quantity.
1. Master & Mold Cost
CAD preparation, master fabrication, silicone mold complexity, parting lines and number of cavities influence the initial investment.
2. Per-Part Casting Cost
Resin consumption, casting labor, curing, demolding, scrap allowance and inspection influence recurring costs.
3. Finishing & Logistics
Painting, texture, assembly, dimensional reports, packaging and shipping may add to the total project price.
How to compare quotes: Ask suppliers to separate mold/tooling charges from per-part prices, specify how many usable parts are expected from each mold, and confirm the total quantity, finish, lead time and inspection scope. No generic online price can accurately represent every custom design.

Vacuum Casting Manufacturing & Quality Control
SENSES MOLD supports custom vacuum cast parts from silicone mold planning through polyurethane casting, finishing, and final inspection. Mold construction, secondary operations, and quality checks are selected according to your CAD drawings, material, appearance, quantity, and functional requirements.
Silicone Molds for Complex Vacuum Cast Parts
We plan silicone mold construction around part geometry, parting lines, cavities, inserts, and demolding risks. Suitable mold approaches include:
- Two-piece molds: straightforward parting and demolding.
- Multi-part molds: complex geometries requiring additional parting lines.
- Core and insert molds: internal cavities and hard-to-access features.
- Flexible undercut molds: features that benefit from silicone's flexibility during demolding.
Silicone formulation is selected for flexibility, tear resistance, dimensional stability, resin compatibility, and expected casting cycles; exact selection is project-dependent.
Vacuum Casting Finishing & Secondary Operations
After demolding, cast components can be finished to meet appearance, fit, and assembly requirements. Operations are specified for each part rather than applied to every project.
Trimming & Deflashing
Remove excess material, flash, and parting-line residue to prepare parts for inspection and assembly.
Sanding & Polishing
Adjust surface texture and gloss where required for functional prototypes or presentation parts.
Painting & Color Matching
Apply project-specified color and appearance finishes for display models and small-batch parts.
Secondary CNC Machining
Machine selected holes, mating faces, or mounting features when casting alone cannot meet the required fit.
Drawing-Based Vacuum Casting Inspection
Quality checkpoints are incorporated into production planning and final acceptance, with attention to the requirements that matter for each custom part.
- Before tooling: confirm CAD revision, material, critical dimensions, and appearance criteria.
- Before casting: review master pattern, mold condition, parting lines, gates, vents, and inserts.
- During casting: check resin identity and the specified mixing, degassing, curing, and demolding conditions.
- Before shipment: inspect agreed critical dimensions, surface appearance, quantity, finishing, and packaging.
Inspection scope and documentation are defined by the project drawing and quotation. Certification claims should be displayed separately only after current certificates and scope are verified.

Vacuum Casting Tolerances for Precision Parts
Vacuum casting can produce accurate, production-like parts when the master pattern, silicone mold, material, and casting process are properly controlled. Our engineers review your drawing requirements and critical dimensions before production.
How Accurate Is Vacuum Casting?
Many vacuum cast parts can achieve around ±0.15–0.30 mm for typical dimensions, depending on part size, geometry, material, mold construction, and process conditions. Tighter tolerances may require additional engineering review or secondary machining.
At SENSES MOLD, critical dimensions are reviewed from the CAD model through master pattern, silicone mold, casting, and final inspection.
For Critical Features
Mating features, mounting holes, and other functional surfaces are reviewed separately. Where tighter accuracy is required, selected features can be finished by secondary CNC machining.
What Affects Vacuum Casting Tolerances?
Master Pattern
The master pattern establishes the dimensional reference for the final vacuum cast part. Our engineers review the CAD data and master pattern requirements before mold making.
Silicone Mold
Mold construction and silicone behavior can affect final part dimensions. Mold design is reviewed according to part geometry, demolding requirements, and expected casting quantity.
Part Geometry
Thin walls, deep cavities, undercuts, and complex features require additional dimensional consideration during mold and casting planning.
Material & Casting
Resin selection, curing behavior, and casting conditions influence dimensional consistency. Material and process requirements are reviewed before production.
Can Vacuum Casting Meet My Drawing Tolerances?
It depends on the required tolerance and part geometry. Our engineers review critical dimensions, mating features, mounting holes, and other functional areas before production. When tighter accuracy is required, selected features can be finished by secondary CNC machining.
How Vacuum Casting Supports More Than Prototyping
Vacuum casting can support more than a single prototype build. With custom silicone molds and polyurethane casting materials, SENSES MOLD produces repeat prototype parts, pilot and validation builds, and low-volume production parts for projects that require production-like polyurethane components in limited quantities.
Repeat Prototype Builds
Need more than one prototype for engineering evaluation or customer review? A silicone mold can produce multiple polyurethane castings from the same master pattern. This makes vacuum casting prototyping practical for repeated design iterations, assembly trials, functional testing, and approval samples.
Pilot & Validation Builds
When your project moves beyond the first prototype, you may need a larger quantity of consistent parts for pilot builds, field testing, customer validation, or pre-launch preparation. Vacuum casting provides repeat polyurethane parts while the product is still being evaluated and refined.
Low-Volume Production
For quantities that are too high for one-off prototypes but still limited in volume, small batch vacuum casting production can provide finished urethane parts for early product launches, market testing, limited releases, and selected end-use applications.
Need Repeat or Low-Volume Vacuum Cast Parts?
Send us your 3D CAD file, required quantity, material requirements, and application. Our engineers can review your project and recommend a suitable vacuum casting solution.
