PVC silicone rapid prototyping polyurethane vacuum casting services
What is vacuum casting?
Polyurethane casting is the process of duplicating a master model
by casting a silicone mold around it. In a highly skilled
procedure, the mold is cut in half, and after the master model is
removed, the gating and venting systems are added. The rapid
fabricator then poured a polyurethane-based resin into the
resulting cavity and cured it under vacuum to prevent the intrusion
of air bubbles. The result is a highly accurate replica of the
original object. The urethane casting process is carried out under
vacuum, so it can produce high-quality bubble-free plastic parts
with a smooth surface texture and no blemishes.
Advantages Of Vacuum Casting
- Low cost for molds
- Molds can be made in a few days
- Many types of polyurethane resins are available for casting,
including overmolding
- Cast copies are highly accurate with excellent surface texture
- Molds are durable for 20 or more copies
- Perfect for engineering models, samples, rapid prototypes, bridge
to production
Advantages of Vacuum Casting Services
| Remarkable Precision |
Vacuum Casting is renowned for its ability to produce highly
accurate and detailed prototypes. The molds used in this process
exhibit excellent dimensional stability, ensuring consistent
replication of complex geometries, intricate textures, and fine
details. Whether it’s a small mechanical component or an
aesthetically appealing consumer product, Vacuum Casting delivers
outstanding precision. This allows the client to get not only the
desired design but also the finishing.
|
| Diverse Material Options |
Vacuum Casting offers a wide range of material choices, enabling
engineers and designers to closely simulate the properties of the
final product. From rigid and flexible plastics to elastomers and
clear parts, Vacuum Casting can replicate various materials,
allowing for functional testing and product performance evaluation.
This versatility is invaluable when creating prototypes that
closely mimic the final product.
|
Cost-Effective Production
|
Compared to traditional manufacturing methods like Tooling and
Injection Molding Vacuum Casting offers significant cost
advantages, particularly for Low-volume Production. The absence of
expensive tooling and molds reduces upfront costs, making it an
attractive option for startups, small businesses, and those in need
of small-batch production. Vacuum Casting enables cost-effective
testing and refinement of designs before committing to large-scale
manufacturing. This is an advantage if you are still in the testing
phase and need to make changes to your prototype.
|
| Rapid Turnaround Time |
Speed is a crucial factor in Product Development, and Vacuum
Casting plastic parts excels at this. The entire process, from mold
creation to casting and curing, can be completed within a matter of
days. This rapid turnaround time allows for quick iterations,
accelerated design validation, and reduced time-to-market. With
Vacuum Casting, businesses can swiftly adapt to market demands and
gain a competitive edge.

Applications of Vacuum Casting
Automotive Industry: Manufacturers use vacuum casting for creating detailed parts such
as dashboard components, lighting assemblies, and prototypes of new
designs. It allows designers to test form, fit, and function before
moving to mass production.
Medical Equipment:In the medical field, vacuum casting is crucial for prototyping
complex parts of medical devices. This includes components for
imaging equipment, surgical tools, and patient-specific models for
surgical planning.
Consumer Products: For consumer goods, vacuum casting is often used to create
high-quality prototypes of household appliances, electronics, and
wearables. It enables designers to evaluate the aesthetics and
ergonomics of products before large-scale manufacturing.
Industrial equipment: production of mechanical equipment test parts.

FAQ:
1.What Kinds of Material Can Be Used For Vacuum Casting?
Ruitai have many kinds of material for vacuum casting including
rubber, similar ABS/PP/PC/PE. And the color is customizable. We
will mix up the color according to your requirements.
2.What Is Vacuum Casting?
The process in which we use a vacuum to mold a molten material is
termed vacuum casting. This process is used when the material is
fiber, or wire-reinforced.
In this process, a small series of functional plastics parts are
produced. Polyurethanes and silicone molds are two essential
components are used in this process. People tend to apply it for
high-quality prototypes or end-use products.
3.Does Vacuum Casting Offer A Wide Range Of Material Choices For
Production?
Vacuum casting provides you a wide range of materials from which
you can choose your favorite ones. There are various options
available for final casting like polymer resins, including stiff
plastic and flexible elastomers and transparent materials.
It is also curable and cast-able resin including many well-known
substances. This means that the Prototype produced by vacuum
casting can have the same aesthetic and mechanical properties as a
mass-produced component made from ABS polyurethane.
