Materials
Available materials
Silicone (RTV) tooling
Master-pattern mold tooling route for vacuum and urethane casting programs.
Extruded aluminum profiles
Custom and standard aluminum profile families subject to die and alloy review.
Extruded PVC / plastic profiles
Profile options for gaskets, trims, channels and selected functional components.
Exact resin, silicone, alloy, plastic grade, color and sourcing requirements are confirmed for each project.
Surface finishes
Finishing options
- Custom color matching
- Texture replication
- Painting
- Pad printing
- Assembly & integration
Finish compatibility, color, texture and cosmetic acceptance criteria require project confirmation.
Design for manufacturing
Master pattern quality
Vacuum-casting quality depends on the master pattern geometry, surface and finishing plan.
Mold life expectations
Silicone tooling output depends on resin, geometry, undercuts and required quality.
Extrusion profile constraints
Review wall transitions, material flow, die feasibility and straightness requirements.
Early design engagement
Bring engineering in early for multi-process assemblies, interfaces and finishing needs.

FAQ
Common questions
When should I choose vacuum casting over 3D printing?
Vacuum casting may be considered when production-representative appearance, material behavior or repeated low-volume parts are more important than direct digital production.
Can your engineers help with design, not just manufacturing?
Design-engineering requests can be reviewed, including DFM, reverse engineering, interfaces and multi-process planning.
Do you handle final assembly?
Assembly, kitting, packaging and related integration requests can be reviewed for multi-part products.
What should I send if the manufacturing process is not yet decided?
Share a CAD model or drawings, the part’s intended function, material or performance requirements, target quantity, finish, critical interfaces, and any existing sample or inspection needs. Mention whether you are considering casting, extrusion, finishing or assembly; if unsure, describe the constraints and target timing. Zenbot reviews the files before recommending a process route and confirming scope, price and lead time. See our manufacturing RFQ checklist for a broader file list.
