What is injection ABS?
ABS is an opaque engineering thermoplastic consisting of a rigid chemical blend designed for high-impact applications.
The Triple-Monomer Advantage: ABS combines Acrylonitrile for chemical and thermal stability, Butadiene for exceptional impact toughness (even at low temperatures), and Styrene for a rigid, glossy finish and excellent processability.
Engineering Precision: Unlike crystalline plastics, ABS is an amorphous material, meaning it has a lower and more predictable shrinkage rate (typically 0.4%-0.7%). This allows us to achieve tight tolerances of +/- 0.01mm using our Fanuc high-speed CNC and Makino EDM.
Secondary Operations: Its chemical structure makes it the best candidate for post-molding processes such as chrome plating, ultrasonic welding, and painting, making it a favorite for high-end aesthetic products.
What is ABS used for?
It is the “workhorse” of the manufacturing world, used whenever a balance of strength and surface quality is required.
Automotive Industry: Used for complex interior components like instrument panels, glove boxes, and center consoles, as well as exterior parts like radiator grilles and wheel covers that require UV-stabilized grades.
Consumer Electronics: The standard for laptop housings, keyboard keys (double-shot molding), and remote controls due to its scratch resistance and electrical insulation properties.
Industrial & Toys: Famous for being the sole material for LEGO bricks because of its incredible dimensional consistency. Also used for power tool housings that must withstand heavy vibration.
Healthcare: Used for non-invasive medical equipment covers and laboratory tool handles that require a non-porous, easy-to-clean surface.
Which is better, ABS or PP?
ABS is an “engineering plastic” for precision; PP is a “commodity plastic” for cost-effective flexibility.
| Performance Metric | ABS | PP |
|---|---|---|
| Mechanical Strength | Superior rigidity; resists deformation under load. | Flexible; exhibits high fatigue resistance (living hinges). |
| Precision Control | Low shrinkage; perfect for mating parts & complex assemblies. | High shrinkage; prone to warping and sink marks in thick walls. |
| Surface Aesthetics | Naturally glossy; excellent for painting/plating | Waxy feel; very difficult for adhesives or paint to stick. |
| Environmental Resistance | Moderate heat/chemical resistance; sensitive to UV. | Excellent resistance to acids, bases, and moisture. |
| Application Logic | Use for High-end Enclosures and Precision Gears. | Use for Hinged Containers, Totes, and Chemical Bottles. |
What is the injection pressure for ABS?
ABS has high viscosity and requires robust pressure (70-120 MPa) to fill complex mold cavities completely.
Fill Stage: We utilize a moderate-to-high injection speed to ensure the melt reaches the extremities of the mold before it begins to solidify, which is critical for thin-walled parts.
Holding & Packing: To combat the material’s natural tendency to shrink, a holding pressure of 30% to 60% of the peak injection pressure is maintained. This ensures the part remains dimensionally stable as it cools.
Back Pressure Management: A low back pressure (typically 5-10 bar) is vital during plasticization. Excessive back pressure can cause shear heating, leading to material degradation or “silver streaks” on the surface.
Is ABS food safe?
Not by default. Standard ABS contains chemicals that may migrate under heat, but specialized food-grade resins are safe for specific uses.
Chemical Concerns: Standard ABS may contain residual monomers or additives that are not approved for contact with fatty or acidic foods.
Thermal Limitations: Standard ABS should never be used in a microwave or dishwasher, as high heat can trigger the release of chemicals.
Compliance Grades: At GBM, we can source FDA-compliant or EU 10/2011 certified ABS for customers in the kitchen appliance or food storage industries. These resins are specifically formulated to be BPA-free and non-leaching.
How to injection mold ABS?
Success requires a “clean” process—dry material, stable temperatures, and high-precision machinery.
Step 1: Scientific Drying: ABS is hygroscopic (absorbs moisture). We dry the resin at 80°C – 90°C for 2-4 hours to reach a moisture content below 0.02%. Failure to do so results in internal voids and surface defects.
Step 2: Precise Thermal Profile: The melt temperature must be strictly controlled between 210°C and 260°C. If the temp exceeds 270°C, the material will turn yellow and lose its impact strength.
Step 3: Mold Temperature Optimization: We maintain mold temperatures at 40°C to 80°C. A higher mold temperature results in better surface gloss and lower internal stress, which prevents the part from cracking later.
Step 4: Quality Validation: After molding, every critical batch undergoes 3D CMM testing and a full dimension report to ensure that the shrinkage was perfectly managed.
