Food Grade Plastic Silicone Vacuum Casting Parts cutlery box
products Customisation 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
Typical technical specification
Time frame
Within 24 hr – 5 working days for up to 30-50 parts
Material choice
Wide variety of materials available
Accuracy
±0.3% (with a lower limit of ± 0.3 mm on dimensions smaller than
100 mm)
Minimum wall thickness
To ensure that the mould is filled properly, a wall thickness of at
least 0.75 mm is necessary. But best results are achieved with a
recommended wall thickness of 1.5 mm
Maximum part dimensions
The size of the mould is limited by the dimensions of the vacuum
chamber
Typical quantities
Up to 50 parts per mould
Surface structure
Gloss to Matt surface finish can be obtained
Silica gel for food is an inorganic polymer colloidal material
condensed from silicic acid, the main component is SiO2-nH2O, the
content of which is more than 98%, non-toxic, odourless, chemically
stable, and does not react with any acid or alkali salts except
caustic soda and hydrofluoric acid under normal conditions. Because
it is a colloidal structure, it has many micropores and a large
specific surface area.
Main Features 1. Non-toxic, odourless, high transparency, non-yellowing; 2. Soft, elastic, resistant to twisting and not deformed; 3. No cracking, long service life, cold and high temperature
resistance; 4. Higher tear strength and superior electrical properties; It has the advantages of high transparency, odourless,
non-yellowing, no frost spraying, especially solving the problem of
frost spraying of black hose and fading of blue products, soft,
high tear-resistant, high insulating, abrasion-resistant,
high-temperature-resistant, flame retardant, anti-ageing,
environmentally friendly, tensile type, stable performance and
other advantages.
