Consumer Electronics Prototyping Vacuum Casting ABS Polycarbonate Mobile Phone Cases Tablet Components

Product Description:

The consumer electronics industry demands high-quality, aesthetically pleasing, and functional plastic components for products like mobile phones, tablets, and wearable devices. Vacuum casting is a popular method for creating prototypes and low-volume production parts for these devices. The process allows for the creation of parts with intricate details, high dimensional accuracy, and excellent surface finishes, which are essential for consumer electronics applications where both form and function are important.

ABS and Polycarbonate are two of the most commonly used materials in vacuum casting for electronics. ABS is highly favored for its excellent impact resistance, rigidity, and ease of processing, making it ideal for the outer casings of mobile phones, tablets, and other consumer devices. It can also be easily molded into complex shapes and provides good chemical resistance, which is crucial for parts that are exposed to handling and wear. Polycarbonate, known for its optical clarity, high heat resistance, and toughness, is often used in consumer electronics for components like screens, lens covers, and other transparent parts that require both durability and aesthetics.

In vacuum casting, the first step is to create a master model, which can be a 3D-printed part or an existing prototype. A silicone mold is then made from this master model, and liquid resins are poured into the mold under vacuum to ensure complete filling and a smooth surface finish. This process is particularly useful for consumer electronics, where manufacturers need to test out prototypes quickly before committing to full-scale production. Vacuum casting enables rapid iteration of designs, allowing manufacturers to quickly create and test different shapes and features for mobile phones, tablets, and other devices.

Vacuum casting is also beneficial for small-batch production runs of consumer electronics components, as it provides cost-effective and high-quality production without the need for expensive injection molding tooling. Whether for prototyping new designs or producing limited quantities of finished products, vacuum casting offers a versatile solution for the consumer electronics industry.

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

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.
