Product Description:
Vacuum casting uses silicon moulds to make a high-quality prototype
of plastic and rubber components using two-component polyurethanes
resins.
What is Vacuum casting?
Vacuum casting, sometimes referred to as Urethane casting or
Polyurethane casting uses silicone moulds to make plastic and
rubber components under vacuum. It is an extremely adaptable
manufacturing process capable of mimicking the injection moulding
to produce complex parts in polyurethane resins and cast nylon.
Due to the process being under vacuum, it produces high-quality
bubble-free casting with smooth surface texture without any
blemishes. Vacuum casting can be extremely useful in rapid prototyping
injection moulding parts and worth considering when selecting rapid
prototyping processes for plastic or rubber parts.
Applications of vacuum casting Vacuum casting is one of the most cost-effective ways to produce
high quality, low volume plastic parts which can be similar to
injection moulding parts
The parts are especially suitable for form, fit and function tests
during the embodiment design stages, where they can be used for
marketing, field user testing and product design verification
purposes
There are many Urethane casting resins commercially available that
can be used to create parts to satisfy a wide range of design
requirements such as temperature requirements, different surface
textures, hardness, etc.
Materials are also available to create parts that are fully opaque,
translucent or completely transparent
Sometimes high-quality wax masters can be made using vacuum casting
for investment casting to increase the finer details of intricate
features

Polyurethane (PU), the full name of polyurethane, is a polymer
material formed by polyol and polyisocyanate through
polycondensation reaction with excellent mechanical properties
[1], which is extremely plastic. Its synthesis can be traced back
to 1937, when Professor Byaer first synthesised straight-chain
linear polyurethane resins using 1,6-hexanediisocyanate and
1,4-butanediol as raw materials
[2]. Several major classifications of polyurethanes include
polyether-type, polyester-type, polyimide-type, and polyurea-type,
etc. They can be made into materials such as polyurethane plastics
(mainly foams), polyurethane fibres (known as spandex in China),
polyurethane rubbers and elastomers
[3].After nearly eighty years of technological development, this
material has a wide range of applications involving products such
as coatings, adhesives, fabric finishes, leather modifiers,
polyurethane soft/rigid foam, elastomers, etc., which are used in
the fields of textiles, construction, aviation, shipping,
transportation, medicine, electronics, and so on.
Flexible polyurethane mainly has a linear structure with
thermoplasticity, which has better stability, chemical resistance,
resilience and mechanical properties than PVC foams, with less
compression variability. Heat insulation, sound insulation, shock
resistance, anti-virus performance is good. Therefore, it is used
as packaging, sound insulation and filtration materials. Rigid
polyurethane plastic is lightweight, sound insulation, superior
thermal insulation performance, chemical resistance, good
electrical properties, easy processing, low water absorption. It is
mainly used in construction, automotive, aviation industry, thermal
insulation structure materials. Polyurethane elastomer performance
between plastic and rubber, oil resistance, abrasion resistance,
low temperature resistance, aging resistance, high hardness,
elasticity. It is mainly used in the shoe industry and the medical
industry. Polyurethane can also make adhesives, coatings, synthetic
leather, etc.
