ABS is highly receptive to various secondary operations, Rally Plastic offers versatile cosmetic and functional finishes.
Find answers about tooling ownership, production capabilities, materials, lead times, and our injection molding process.
ABS plastic injection molding is a highly efficient manufacturing process where Acrylonitrile Butadiene Styrene pellets are melted and injected under high pressure into a precise steel cavity. Once cooled, the thermoplastic solidifies into a durable, impact-resistant part. At Rally Plastic, our engineers leverage this process to produce complex geometries with excellent surface finishes and dimensional stability.
| ABS Property | Typical Value |
|---|---|
| Tensile Strength | 40–50 MPa |
| Flexural Strength | 65–75 MPa |
| Impact Strength (Izod) | 200–300 J/m |
| Heat Deflection Temp. | 95–105°C |
| Material Shrinkage | 0.4%–0.7% |
| Water Absorption | 0.2–0.4% |
| Density | 1.04 g/cm³ |
Yes, Polycarbonate (PC) and ABS can be successfully dual injection molded (two-shot molding) because they share excellent chemical compatibility and similar processing temperatures. When molded together, they form a robust mechanical and chemical bond without requiring separate adhesives. Rally Plastic frequently utilizes this technique to combine the extreme impact resistance and transparency of PC with the superior machinability and cost-efficiency of ABS, creating highly durable, multi-functional enclosures for premium electronic and automotive components.
Choosing between these common thermoplastics depends entirely on your specific application. ABS offers an excellent balance of cost, impact resistance, and superior surface finishes (like electroplating). PC (Polycarbonate) provides higher heat resistance, transparency, and extreme impact strength, but at a higher material cost. PP (Polypropylene) excels in chemical resistance and flexibility—perfect for living hinges—but is difficult to paint or glue. If you have any questions, please contact Rally Plastic's engineers for your own recommendation.
Technically, it is generally not recommended to use the same injection mold for both ABS and nylon (PA) without tooling modifications. Nylon has a significantly higher shrink rate (often 1.0%–1.5%) compared to the 0.4%–0.7% typical for ABS. If you inject nylon into a tool cut specifically for ABS, the resulting parts will likely be undersized and fail dimensional tolerances. Additionally, nylon requires much higher melt and mold temperatures, which might exceed the thermal design limits of the existing ABS mold.
Sink marks in ABS molding usually occur due to uneven cooling and thermal contraction in thicker sections of the plastic part. To prevent this, engineers must adhere to strict Design for Manufacturing (DFM) guidelines. The most critical rule is maintaining a uniform wall thickness. If reinforcing ribs are necessary, their base thickness should not exceed 60% of the adjacent nominal wall. Furthermore, optimizing holding pressure and extending cooling times within the m
