Plastic Injection Molding

With over 50 years of plastic injection molding experience, P&P Industries differentiates itself through disciplined leadership and a long-standing commitment to continuous reinvestment in manufacturing technology and capacity. This ongoing investment enables us to support complex molding programs with consistency, scalability, and long-term reliability.

Our operation features a wide press range from 50 to 780 tons, supported by on-site design and process engineers and advanced Scientific Injection Molding methodologies. This combination allows P&P Industries to serve a diverse range of industries while delivering high-quality, repeatable injection-molded parts tailored to each customer’s requirements.

P&P Industries is powered by a skilled workforce dedicated to Continuous Improvement and lean manufacturing principles. By eliminating waste, improving process stability, and prioritizing accountability at every stage of production, we maintain customer satisfaction as a core operating focus—not an afterthought.

All plastic injection molding machines are equipped with modern process monitoring and control technologies, enabling repeatable, shot-to-shot consistency. This data-driven approach reduces variation, increases efficiency, and helps keep production costs competitive—without compromising quality or performance.

P&P Industries operates a documented Preventive Maintenance (PM) program, with all customer molds placed on a scheduled and traceable maintenance plan. This proactive approach protects tooling investments, minimizes unplanned downtime, and ensures consistent part quality over long production runs.

Leveraging decades of injection molding experience, ongoing education, and certified processes, P&P Industries simplifies even the most complex molding programs. Our engineering team can collaborate with customers during part design or conduct in-depth reviews of existing molds to improve manufacturability, performance, and cost efficiency.
