Why Choose ABS Plastic for Injection Molding?

ABS, or Acrylonitrile Butadiene Styrene, is a widely-used thermoplastic polymer that is commonly injection-molded into various components. Known for its affordability and impressive durability, ABS is also relatively easy to machine. This makes it a popular choice for producing parts in industries such as automotive, electronics, and construction. Its versatility and cost-effectiveness have made ABS a go-to material for manufacturers worldwide. If you're curious about why ABS is so favored for injection molding, keep reading to explore its unique properties and advantages.

Understanding ABS Plastic

ABS plastic is essentially a blend of three main components: acrylonitrile, butadiene, and styrene. Acrylonitrile contributes to the material's hardness and improves its chemical and heat resistance. Butadiene adds impact resistance and toughness, while styrene enhances the overall strength, gloss, and processability of the plastic. On its own, ABS lacks resilience against weathering and UV exposure. To address this, additives such as acrylic, nylon, glass fibers, and even stainless steel fibers are often incorporated to enhance its outdoor durability.

Key Material Properties for Injection Molding

When working with injection molding polymers, understanding key material properties such as water absorption and mold shrinkage is essential. These factors directly influence the processing and drying stages of manufacturing.

  • Mold Shrinkage: This measures the amount of shrinkage during cooling and helps determine the final product's dimensions. For ABS, the typical shrinkage rate ranges between 0.0040 to 0.0070 inches.
  • Water Absorption Rate: When submerged in distilled water at 23 degrees Celsius for 24 hours, ABS absorbs moisture, increasing its weight by approximately 0.16 to 0.25%. This percentage reflects the material's water absorption rate.
  • Drying Temperature: Proper drying ensures optimal performance. The recommended drying temperature for ABS lies between 176°F and 180°F.
  • Drying Time: Depending on the application, ABS may require 2 to 9 hours of drying to remove moisture effectively.
  • Melt Temperature: The melt temperature for ABS falls within the range of 410°F to 500°F, ensuring smooth flow during injection molding.

Why Choose ABS Plastic for Injection Molding?

ABS plastic is not only cost-effective but also boasts several standout advantages that make it a top choice for manufacturers.

  • ABS is less expensive than many other plastic resins, making it an economical option without compromising on quality.
  • It exhibits high tensile strength, providing excellent structural integrity.
  • With strong chemical resistance, ABS is ideal for demanding environments where corrosion or chemical exposure is a concern.
  • This plastic is highly versatile, offering a variety of colors, textures, and finishes to suit diverse design requirements.
  • Its lightweight nature facilitates easy molding into complex shapes and designs.
  • ABS is fully recyclable, promoting sustainability in manufacturing processes.
  • It resists oils, acids, and alkalis, making it suitable for industrial applications.
  • ABS demonstrates exceptional ductility, creep resistance, and stability under stress, ensuring long-term reliability.
  • Its tensile strength and stiffness are unmatched in many comparable materials.

Applications of ABS Plastic Injection Molding

The adaptability of ABS plastic has led to its widespread use across multiple industries. Some of the most common applications include:

  • Electronics: From remote controls to computer casings, ABS is a staple in consumer electronics.
  • Automotive: Interior components, dashboard elements, and car bumpers frequently utilize ABS for its strength and impact resistance.
  • Food and Beverage: Containers and packaging materials benefit from ABS’s safety and durability.
  • Sports Equipment: Helmets, balls, and other sports gear rely on ABS for its robustness and flexibility.
  • Fittings: Plumbing fixtures and household items often incorporate ABS for its ease of fabrication and durability.

Small Cement Silo

Small Cement Silo

1.The cement silo must be erected by a special crane when working. Then place it on the prefabricated concrete and check the verticality between cement silo and the horizontal level. Then weld the bottom of the silo with embedded parts firmly.


2.After the silo is fixed, bulk cement truck transports the cement to site. Then conveying the cement in truck to cement silo by the air pressure of the truck.

3.In the process of conveying cement to storage bin, the operator should press the button of dust collector uninterruptedly to shake off the cement attached to the duster bag to prevent blocking and silo explosion.

4.Once the bag is blocked and the pressure in the silo exceeds the safety pressure value , then open the safety pressure valve to release the inner pressure, to avoid the explosion accident.



Cement silo working principle:

1.Bulk cement truck transports the cement to the site.

2. Conveying the cement in truck to cement silo by the air pressure of the truck.

3. Conveying the cement in cement silo to the Concrete Mixer by the Screw Conveyor.
