ABS Plastic Injection Molding

ABS Plastic Injection Molding

Thermoplastics are the most common plastic-type widely used in the plastic injection molding industry. Thermoplastics have a wide range of characteristics that very much suit the needs of plastic injection molding. Among the characteristics, including flexibility, physical strength, and design, the ABS 3D printed plastic injection mold has been recognized as one of the best thermoplastic products within the plastic injection molding industry. We can find this plastic in most of the areas in everyday life. We can find that various automotive goods, electronic appliances, consumer goods, sporting accessories, and many other supplies are made up of ABS thermoplastic through the plastic injection molding process.

To be familiar with the abs plastic injection molding process, we should know the composition, nature, and properties of abs plastic pellets for injection molding. ABS stands for Acrylonitrile Butadiene Styrene. It is a copolymer, as we can see, composed of monomers. The nature of this thermoplastic is opaque. Property wise it is amorphous without a true melting point. Other properties of ABS thermoplastics include temperature resistance, heat resistance, and other additive qualities.

The properties of ABS are unmatchable. They are versatile, have great machinability, and have numerous industrial applications. Besides, these thermoplastics are also variably used in aerospace plastic injection molding, sports equipment, and medical devices.

The various types of ABS plastic injection molding include medical molding, ultrasonic bonding, and micro molding.


Among the various advantages of ABS plastics include their benefits in terms of:

  • Physical strength and toughness

  • High force of tension

  • Good dimensional strength

  • Better machine quality

  • Great resistance to fluids like oil, acid, and alkali

  • Stability during high loading

  • Good ductility


Various implementable conditions for ABS plastic injection molding

To keep the ABS devoid of moisture, the ABS needs to be kept dried before processing. The temperature conditions for drying are maintained between 80-90 degrees Celsius to be fixed for two hours. Thus, the moisture content remains of the material below 0.1 percent.

Melting Point of the material is kept between 200 – 280 degrees Celsius to achieve 230 degrees Celsius temperature as the limit.

The design parameters for the abs plastic injection molding machine include gate and vent thickness to be set to 3mm, which is maintained throughout the whole vent cross-section. The length of the gate is kept to be less than 1mm. Whereas the thickness of the vent is maintained between 0.025 – 0.05mm.Gate length should be less than 1 mm.

ABS is a great all-round engineering plastic and can be found in molds of wall sockets, automotive trim, printers, vacuum cleaners, hard hats, kitchen utensils, plastic toys, and musical instruments

ABS cannot be considered as a harmful thermoplastic in general. ABS does not contain chemicals that cause any severe disease or produce side effects causing adverse health conditions. Still, ABS cannot be considered as a good thermoplastic for medical implants.
