Vacuum Casting Creating Durable Automotive Interior Parts Dashboard Components Switches ABS PVC

Product Description:

The automotive industry requires high-quality, durable, and functional plastic parts for both exterior and interior components. Vacuum casting is increasingly being used for the production of automotive interior parts, such as dashboard components, switches, and trim pieces, as it allows for precise, high-quality parts that meet the aesthetic and mechanical demands of the automotive market. ABS (Acrylonitrile Butadiene Styrene) and PVC (Polyvinyl Chloride) are two commonly used materials in automotive interior applications due to their strength, impact resistance, and ease of processing.

ABS is a highly versatile plastic that provides excellent rigidity and impact resistance, making it ideal for producing components that must withstand constant use and potential impacts. It is commonly used for dashboard elements, center consoles, and trim pieces that need to be both functional and aesthetically pleasing. PVC, on the other hand, is widely used in automotive applications for its ability to be molded into complex shapes and its durability against wear and tear. It is commonly found in parts like switch housings, instrument clusters, and door panels.

The vacuum casting process for automotive interior parts begins with the creation of a master model, which is then used to create a silicone mold. Liquid ABS or PVC resin is injected into the mold, and a vacuum is applied to ensure the resin fills every part of the mold, resulting in parts with excellent surface quality and dimensional accuracy. This process allows manufacturers to create intricate, detailed parts with minimal defects, which is crucial in automotive interior applications where both function and appearance are critical.

Vacuum casting is particularly beneficial for low-volume production runs of automotive interior parts, as it allows for the rapid prototyping and manufacturing of custom components. Manufacturers can quickly test different design iterations, ensuring that the final parts meet both functional requirements and aesthetic preferences. Whether it’s producing custom dashboard elements, switches, or other interior components, vacuum casting offers an efficient and cost-effective solution for producing high-quality plastic parts for the automotive 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.
