Why ABS is the Preferred Engineering Plastic

ABS (Acrylonitrile Butadiene Styrene) combines the strength and rigidity of acrylonitrile and styrene with the toughness of polybutadiene rubber. This unique combination creates an engineering thermoplastic with exceptional balance of properties.

Superior Impact Resistance

Excellent toughness even at low temperatures, maintaining strength under mechanical stress and impact loads

Dimensional Stability

Low shrinkage rate and excellent dimensional stability ensure tight tolerances and consistent part quality

Excellent Surface Finish

Smooth surface allowing easy painting, plating, and printing for aesthetic enhancement

Easy Processing

Good melt flow properties facilitate complex part geometries and thin-wall molding

Design Guidelines for ABS Parts

Best Practices

Uniform Wall Thickness

Maintain 1.5-3.5mm thickness for optimal flow and minimal sink marks

Generous Radii

Use 0.5mm minimum radius to reduce stress concentration points

Draft Angles

Include 1-2° draft on vertical surfaces for easy ejection

Ribbing Design

Rib thickness should be 50-60% of nominal wall thickness

Avoid These Issues

Sharp Corners

Sharp transitions create stress points and reduce part strength

Thick Sections

Excessive thickness causes sink marks and longer cycle times

Deep Ribs

Overly deep ribs can cause warping and surface defects

Undercuts Without Action

Complex undercuts require expensive side actions or lifters

Frequently Asked Questions

What are the key advantages of ABS for injection molding?

ABS offers excellent impact resistance, superior surface finish, good dimensional stability, and easy processing. It can be easily painted, plated, or printed for aesthetic enhancement. ABS maintains properties over wide temperature ranges and provides good strength-to-weight ratio making it ideal for consumer products and automotive applications.

Can ABS parts be chrome plated?

Yes, ABS is the preferred material for chrome plating due to its excellent adhesion properties. We offer plating-grade ABS specifically formulated for electroplating applications. The smooth surface and chemical properties of ABS allow for high-quality metallic finishes commonly used in automotive trim and decorative applications.

What is the typical shrinkage rate for ABS?

ABS typically exhibits 0.4-0.7% shrinkage, which is relatively low compared to other thermoplastics. This low shrinkage rate contributes to excellent dimensional stability and tight tolerance capability. Our mold design accounts for material-specific shrinkage to ensure parts meet dimensional specifications.

Is ABS suitable for outdoor applications?

Standard ABS has limited UV resistance and may degrade with prolonged outdoor exposure. However, we can process UV-stabilized ABS grades or ASA (weatherable ABS alternative) for outdoor applications. Surface coatings and paints also provide additional UV protection for ABS parts used outdoors.

What secondary operations are available for ABS parts?

We offer comprehensive secondary services including painting, chrome plating, pad printing, hot stamping, laser marking, ultrasonic welding, and assembly. ABS excellent surface properties make it ideal for various finishing processes. We can deliver fully finished and assembled products ready for your end use.
