Kaierwo, an expert in the manufacture of automoticve parts

About the application of materials

• Acrylic(PMMA)

  We use acrylic to produce transparent parts such as automobile lamp instrument and meter.It’s often used as an alternative to glass due to its high tensile strength and weather and scratch resistant nature. It takes dyes and colorants very well so it can produce many aesthetic effects.

• Polystyrene(PS)

  When it comes to injection molding resins, We commonly used to two types of polystyrene: High Impact Polystyrene (HIPS) and General Purpose Polystyrene (GPPS). GPPS is transparent, while HIPS is opaque. Toolboxes and lampshades are also made using High Impact Polystyrene. PS is tough and durable. It can take a lot of abuse in the field.

• Acrylonitrile Butadiene Styrene ( ABS)

  Due to the variety of ABS, good surface treatment effect and low price, it is widely used in the automotive field. We often produce a variety of automotive products through a series of ABS processing, such as decorative light strip, shift handle head, inner open handle, license plate decoration plate, handrail and so on.

• Polypropylene (PP)

  PP has good fluidity and low water absorption in injection molding. When we use PP, we will add appropriate additives to do PP modification. Easy to burn will add flame retardant; It is brittle at low temperature. It is mainly modified by adding other ductile materials, rigid particles or elastomers, such as rubber (EPDM), talc powder (TD), glass fiber (GF), etc. We usually use PP resin to manufacture various auto parts such as instrument panel, door guard panel, bumper, water tank, decorative panel.

• Steel Plate Cold Commercial(SPCC)

  SPCC through cold rolling treatment can get thinner thickness, higher precision cold rolled strip steel and steel plate, its flatness is high, high surface finish, further processing to our car inner plate, outer plate, support parts.

• Aluminium

  The application of aluminum in automobiles is very common. Under normal circumstances, we will CNC process aluminum to produce a variety of metal accessories in automotive.

• Exterior CNC machining +silicone mold prototype car components

  Silicone molds are a replication technology that we use to produce small series of functional plastic automotive parts. Vacuum casting is famous for its rapid production of high-quality prototype or end-use products. This makes vacuum casting models particularly suitable for fit and functional testing, marketing purposes or a limited number of final parts. The manufacturing technology is very suitable for low batch production when injection molding is not cost-effective; Usually a mold can be used to produce up to 15-20 parts before it needs to be reworked. Therefore, we can get high-quality prototypes and save a lot of costs. Examples: Mudfenders (fenders), automotive light wheel arches, grilles, sensor supports, floor tracks, trunk trims, front and rear coverings, bumper and exterior door trims, door panels.
• Why work with us?

  Kaierwo as a plastic and metal auto part manufacturerand supplier, specializes in silicone mold prototype and injection molding mass production technology over 12 years.We have profeesional team and rich expriences to meet your demand.In addition,our all autpmotive parts are manufactured at our Shenzhen facilities,providing you with a one-stop service.

Common auotomotive manufacturing service

• CNC Machining

  Advanced multi-axis NC machines produce unlimited volumes of finished parts from virtually any commercially available raw stock, and they do so quickly and with great accuracy

  We use CNC machining to make enclosures as well as engineering-grade fittings in support of automotive parts made from a wide range of ferrous and non-ferrous metals as well as hard plastics.

• Sheet metal fabrication

  The sheet metal fabrication is a widely used metalworking technology that plastically deforms a thin metal sheet by an external step force, exceeding the material’s yield strength, bending and drawing into various complicated shapes without reducing the material itself. We provide customized precision parts processing services and technical support, combining metal stamping, metal casting, metal sheet metal forming, surface treatment, metal heat treatment and other processes, a true one-stop supplier of automotive parts.

• Vacuum casting

  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 similar to painting effect.

  It is one of the most cost-effective ways to produce high-quality, low-volume plastic parts that are particularly suitable for automotive prototypes and can be tested for form, fit and function during the

• Rapid Tooling

  This a fast and cost-efficient way to carry out low-volume injection molding for a variety of types of plastic parts. Once the aluminum or steel mold has been created with the rapid tooling process, it can be utilized as part of a molding process to create multiple copies of a part.

  
  

  Our custom rapid tooling service is a cost-effective, low-volume alternative in situations where large volumes of the part won’t be needed in the future.
