Manufacturing Vacuum-Cast Plastic Parts Packaging Sector PET PVC Custom-Made Bottle Caps Containers

Product Description:

The automotive industry demands components that can withstand extreme stress, high temperatures, and constant wear. Vacuum casting offers an ideal method for producing high-performance plastic parts for automotive applications, such as engine components, trim pieces, and interior elements. Materials like PEEK (Polyetheretherketone) and ABS (Acrylonitrile Butadiene Styrene) are often selected for these applications due to their excellent mechanical properties, heat resistance, and dimensional stability.

PEEK is a high-performance material that excels in extreme environments, making it ideal for automotive engine components and parts that are exposed to high temperatures, friction, and chemical exposure. It is used in applications such as fuel systems, engine components, and connectors, where performance and reliability are critical. ABS, on the other hand, is a versatile plastic that provides excellent impact resistance, toughness, and ease of processing, making it ideal for producing interior trim pieces, dashboards, and panels.

Vacuum casting for automotive parts begins by creating a master model, often using 3D printing or CNC machining. This model is then used to create a silicone mold, which captures the intricate details of the design. Liquid PEEK or ABS resin is injected into the mold, and a vacuum is applied to remove air bubbles, ensuring that the resin fills every cavity and produces parts with smooth surfaces and precise dimensions.

Vacuum casting provides automotive manufacturers with a cost-effective and efficient way to produce prototypes and low-volume production runs of high.

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.
