ABS is one of the most popular material options for injection molding, since it has good resistance to acids and bases. ABS injection molding refers to the process of injecting molten ABS plastic into a mold at high pressures and temperatures. High-quality ABS plastic injection molding services with the low cost for a variety of industries are available to consumers in Echofast,and that’s why our ABS injection molding services are highly popular.
To get the injection molds you need,it’s significant to follow general molding guidelines which you’ll find in our design guide:
| Maximum Part Size | 18.9 in. x 29.6 in. x 8 in. (480mm x 751mm x 203mm) |
| Maximum Volume | 59 cu. in. (966,837mm) |
| Recommended Wall Thickness | 0.045 in. - 0.140 in. (1.143mm - 3.556mm) |
| Tolerances |
+/- 0.003 in. (0.08mm) with an included resin tolerance that can
be greater than but no less than +/- 0.002 in./in. (0.002mm/mm) |
Typical mechanical properties of ABS

If you’re wondering whether ABS plastic might be the right choice for your injection molds,consider some advantages of this popular polymer.
1. Energy Efficiency
ABS injection molding is a highly efficient and productive manufacturing technology, which can help you reduce energy demand and overall cycle times.The highly automated nature of the technology results in the low cost of labor while it offers you large volumes of high-quality parts.
2. Recyclable
Once an ABS plastic part has reached the end of its life,it can be fully recycled back into ABS material by grinding the part and remelting it with new ABS into stock material. Due to the good recyclability,ABS has become a perfect material for use in reusable applications.
3. Aesthetic Appeal
By using acetone vapor or other finishing processes,ABS plastic is easily colored with a wide range of colors and can achieve a high gloss.Therefore,ABS is a versatile thermoplastic often used in automotive,medical device and consumer applications like toys and models.
4. High Tensile Strength
Because of its strong and lightweight thermoplastic property,ABS is desirable for applications requiring increased durability and overall mechanical strength.
5. Accurate Reproducibility
ABS is the most suitable material in making complex parts for its processability,which can make it easy to reproduce complex and functional parts. Functional integrity can be maintained in the process of ABS injection molding even when used in extreme conditions due to the hardness of the plastic as well.
In spite of its numerous advantages,ABS also has its shortcomings . Some of these disadvantages include:
1. Poor UV Resistance
ABS plastic tends to degrade in the presence of ultraviolet (UV) light. As a result,it fails to function as a suitable material for outdoor equipment. Therefore,it dawns on that manufacturers can add additives to the ABS plastic.
2. Poor Fatigue Resistance
Though ABS plastic has relatively high tensile strength,it can’t withstand heavy loads for long periods with the poor fatigue resistance. It may degrade easily upon continuous exposure to stress or strain.
3. Poor Friction and Wearing Behavior
When it comes to injection molded parts for bearings,friction components,or otherwise high-wear environments,pure ABS is not a good material for its poor friction and wearing behavior.
4. High Smoke Evolution
Once ABS is heated far above its melting temperature,toxic fumes will be released,which are harmful to operators and technicians. It is a serious health concern for those who inhale pollutants like toxic fumes.Therefore,tight temperature controls must be used to prevent smoke evolution and toxic off-gassing among manufacturers.
ABS is a good choice in that it is a tough,impact-resistant plastic at the low cost. ABS injection molding is used across a wide range of industries. Here are some examples :
