What is vacuum casting or polyurethane casting?
Vacuum casting is a manufacturing process similar to injection
molding, in which polyurethane resin is cast in a cavity between
two silicone molds.
This process replicates the main model by pouring a silicone mold
around the model. In a highly skilled procedure, the mold is cut in
half, the
main model is removed, and then pouring and ventilation systems are
added.
There are many advantages of vacuum casting, which makes it popular
in rapid prototyping and small batch production:
- Cost-Effectiveness: Vacuum casting is significantly more economical than other
manufacturing processes like injection molding for small to
medium-sized production runs. The initial setup costs are lower,
and the process allows for quick and affordable modifications.
- High-Quality Results: The process yields parts with excellent surface finishes, fine
details, and high dimensional accuracy. This is particularly
important for prototypes that need to closely resemble the final
product.
- Material Versatility: Vacuum casting offers the flexibility to use a wide range of
materials, including various types of resins that can mimic the
properties of different plastics, rubbers, and even metals. This
versatility is essential for testing different material properties
in prototypes.
- Speed: The turnaround time for vacuum casting is relatively short,
making it ideal for rapid prototyping. This quick production cycle
allows companies to accelerate their product development and
time-to-market.
- Customization and Complexity: Vacuum casting can handle complex shapes and intricate details
which might be challenging or impossible to achieve with other
manufacturing methods. It also allows for a high degree of
customization in terms of colors and finishes
Multiple Benefits of Small Batch Rapid Prototyping Urethane Casting
Parts
High accuracy and detail:Urethane casting allows for the creation of precision mechanical
parts with high levels of accuracy and detail. This makes it an
ideal process for producing parts that require precise dimensions
or intricate shapes.
|
Durability:Urethane casting parts are known for their durability and
resistance to wear and tear. This makes them suitable for use in
applications where the part will be subjected to a lot of stress or
friction.
|
Range of properties:Urethane casting allows for the creation of parts with a wide range
of physical properties, including hardness, flexibility, and
resistance to heat and chemicals. This makes it possible to create
parts that are tailored to specific applications.
|
Fast turnaround: The process is relatively fast, and the lead time for mold
creation and parts production is short. This speed is beneficial
for meeting tight project timelines and getting products to market
faster.
|
Short lead times:Because urethane casting does not require expensive tooling, parts
can be produced relatively quickly. This makes it possible to get
parts to market faster than with other manufacturing processes.
|
Vacuum polyurethane castings are widely used in industries such as
automotive, consumer electronics, medical devices and aerospace
to develop prototype or limited edition parts. They are also ideal
for functional testing, visualizing models, or making small batch
production runs
of complex or high-detail components.
Plastic Vacuum Casting Parts with Different Color
Vacuum casting is the same as polyurethane or urethane casting. It
is a process in which liquid resins are drawn into a mold with a
vacuum
to make plastic or rubber parts. A vacuum expels air bubbles from
the mold to ensure the cast parts take on the intended shape.
Rubber,
resins, and thermoplastic are the liquid materals commonly used for
urethane casting.

This casting process is ideal for producing accurate, functional
prototypes that closely mimic the mechanical properties and
appearance
of the final product. Polyurethane materials can be formulated to
replicate various properties such as flexibility, hardness, and
durability, making them suitable for testing, display, and even
short-term production. It can also be used to create parts with
complex details or complex geometrics.
The benefits of 3D printing technology
- Possibility of using flexible, transparent or rigid materials, with
mechanical and thermal characteristics similar to those of
mass-produced materials;
- Numerous finishes ;
- Possibility of overmolding and adding inserts;
- 3D part tinted in the mass;
- Wide range of technical resins;
- Soft/rigid bi-material moldings.
The choice between vacuum casting and 3D printing depends on the
specific application and requirements of the part being produced.
For small to medium-sized production runs, vacuum casting may be
more cost-effective and efficient, especially when using 3D
printing
to create the master model. However, for one-off or highly
customized parts, 3D printing may be the better option.
