PS PE Silicone Food Grade Plasctic Vacuum Casting Parts cutlery box 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

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.
