Innovative Solutions for Plastic Part Production


Learn to overcome challenges facing the injection molding industry. Evaluate the needs vs. equipment (for injection molding). Present the selection of molds available and criteria for choosing them. Identify day-to-day issues that arise with the quality of injection- molded parts. Offer solutions and suggestions to help you in your injection molding arena.

Our goal will be to have you return to your organization with innovative ideas that will aid in producing higher quality, faster and more economical parts.

Who Should Attend

Plastic part designers, processing engineers, production managers, individuals involved
in production of unique parts, and engineers and managers involved in reducing
production time while maintaining quality.
