To prevent part defects, consider the mold shrinkage (0.004 to 0.007 inches) and water absorption (0.16% to 0.25%) of ABS. These properties affect curing and processing. Other properties to consider when ABS molding are:

ABS refers to acrylonitrile butadiene styrene, a thermoplastic polymer commonly used for injection molding. The primary ingredients of acrylonitrile, butadiene, and styrene each impart specific properties to ABS injection molded parts. Acrylonitrile adds hardness and provides heat and chemical resistance. Butadiene offers added toughness and impact resistance. Styrene adds strength, gloss, and workability.

Plastic injection molding is a manufacturing process that injects melted plastic using high pressure into a pre-shaped mold to create products with particular specifications. Lerner Molded Plastics provides injection molding design services for ABS injection molding projects. We have over 35 years of experience designing injection molds and a cutting-edge injection molding facility. Here you can learn more about ABS injection molding and its benefits, applications, and considerations.

How to Get Certified:Our Certification Exam for Injection Molding Maintenance is conducted entirely online. This comprehensive test takes approximately 1.5 hours to complete — with a time limit of 3 hours. Upon completion of the exam, participants are immediately notified whether they’ve passed or not, via email.

Who Should Consider Maintenance Certification?Maintenance technicians, managers, and engineers should consider taking this exam. Managers should offer this certification to benchmark their team — ensuring that maintenance personnel are confident, capable, and knowledgeable.

Those who attain a passing score will receive their certificate. Those who do not pass receive a detailed report indicating areas in which further improvement is needed, prior to retaking the exam.

In order to attain certification, candidates must have a working knowledge of injection molding safety, robotics, drying, machinery, materials, purging, robotics, parameters, hydraulics, and maintenance — and demonstrate a solid understanding of current industry best practices.

In ABS injection molding, ABS plastic pellets are melted and injected into the cavity of a two-part mold that forms a single part. As soon as the mold is filled, the plastic will solidify and cool into the shape of the mold.
