Our strategic location in Chino allows us to serve all of Orange County with next-day delivery within 20-40 miles of our facility. We've invested in state-of-the-art plastic injection molding equipment with large tonnage capacity up to 2800 tons, allowing us to handle projects of any size. Our expertise in precision plastic injection for non-invasive medical-grade production, electronics, consumer products, and tech industries has made us the preferred partner for businesses throughout Southern California. Our commitment to quality control and innovative approaches to plastic materials selection ensures we provide custom solutions that consistently exceed client expectations.

Our plastic injection molding facility works with a diverse range of plastic materials to suit different application requirements. We regularly process thermoplastic molding materials including ABS, polycarbonate, nylon, polyethylene, polypropylene, acetal, and specialized resins for demanding applications. In addition to traditional thermoplastic molding, we also offer polyurethane molding services for applications requiring enhanced flexibility or impact resistance. Our engineering team helps select the optimal plastic materials based on your specific needs for mechanical properties, chemical resistance, temperature tolerance, and cost considerations. Whether you need plastic injection for consumer products or high-performance plastic gears for industrial applications, our plastic injection molding expertise ensures optimal performance in every plastic component we produce.

As a premier Southern California mold maker, Norco Plastics excels in both precision mold making and efficient plastic injection production. Our mold making expertise spans over 50 years, allowing us to design and fabricate injection molds with exceptional precision and durability. Our comprehensive mold making services include concept development, 3D modeling, prototype creation, tool design, and production implementation. The mold maker team maintains a Class 10000 clean room environment for creating molds for critical components, particularly for medical and electronic applications. This controlled environment, along with our rigorous quality control protocols, ensures contamination-free plastic components that meet the most stringent industry standards. Additionally, our capabilities extend to blow molding and polyurethane molding, providing clients with a complete range of plastic manufacturing solutions under one roof.

Our manufacturing process incorporates multiple quality assurance protocols throughout the plastic injection production cycle. We begin with comprehensive material testing in our Class 10000 clean room environment to ensure consistency and purity of all plastic materials. During setup, our engineers optimize all processing parameters, including temperature profiles, injection speeds, pressure settings, and cooling times. Throughout production, our automated monitoring systems track key metrics in real-time, allowing immediate adjustments to maintain precise tolerances. Each plastic component undergoes rigorous inspection for dimensional accuracy and structural integrity. For critical applications, we employ advanced techniques including optical measurement, stress analysis, and material certification. This systematic manufacturing process approach, combined with our commitment to continuous improvement, allows us to produce consistently high-quality plastic injection molded parts ranging from precision plastic gears to complex medical components.

While plastic injection molding excels at creating solid, intricate components, blow molding offers distinct advantages for hollow plastic parts. Our blow molding capabilities complement our core plastic injection services, allowing us to produce containers, bottles, and other hollow vessels efficiently. Blow molding typically offers lower tooling costs than comparable plastic injection molds for hollow parts, making it economical for certain applications. The blow molding process creates seamless, one-piece hollow products with excellent uniformity in wall thickness. For enhanced flexibility and shock absorption, we also offer polyurethane molding services. Polyurethane molding is ideal for creating resilient components that require exceptional durability and impact resistance. This polyurethane molding process allows for greater design freedom and material property customization. Our expertise in multiple manufacturing techniques enables us to recommend the optimal process for each project based on design requirements, production volume, and cost considerations.

Our customer service approach is built on transparent communication, technical expertise, and responsiveness to client needs. As a leading Southern California plastic injection molding provider, we assign dedicated project managers who serve as your primary point of contact throughout the manufacturing process. These customer service professionals coordinate between our engineering, production, and quality control teams to ensure seamless project execution. Our client support team utilizes advanced project management software to provide real-time updates on production status, allowing customers to monitor progress. We offer flexible scheduling options, including urgent project capability for time-sensitive needs, with our 24/7 operational capacity for uninterrupted production. Additionally, our strategic Chino location enables efficient delivery throughout Southern California, with same-day service possible for Inland Empire clients and next-day delivery to Los Angeles and Orange County. This commitment to exceptional customer service has resulted in long-term relationships with clients across diverse industries.
