About Us
Precision Plastic Manufacturing Since 1984
Hope Plastics Co Inc is a full-service custom plastic manufacturer headquartered in North Hollywood, California. For over 40 years, we have delivered precision injection molding, blow molding, cleanroom manufacturing, and secondary services to the most demanding industries in the world.
Our Story
Built on Precision, Driven by Quality
Founded in 1984, Hope Plastics Co Inc began as a small injection molding shop in the San Fernando Valley. Over four decades, we have grown into a comprehensive custom plastic manufacturer with capabilities spanning rapid prototyping, in-house tooling, injection molding, blow molding, cleanroom medical molding, liquid silicone rubber molding, thermoforming, rotational molding, and a full suite of secondary services.
Our growth has been driven by a simple philosophy: treat every customer's part as if it were our own. That means investing in the certifications, equipment, and talent required to serve the most demanding programs in medical, aerospace, defense, automotive, and industrial markets — and delivering on time, every time.
As an NMSDC-certified Minority Business Enterprise (MBE) and Small Business Enterprise (SBE), we bring the capabilities of a large manufacturer with the responsiveness and personal attention of a dedicated team. When you work with Hope Plastics, you work directly with the people who build your parts.
