Hi-Rel Plastics & Molding Corp. provides vacuum forming services alongside a full range of precision plastic manufacturing capabilities, including injection molding and thermoforming. From part evaluation and prototyping to tooling, forming, trimming, assembly, and production, we support every stage of your project with quality and consistency.
With more than 40 years of experience, we partner with manufacturers in Riverside and across the United States to produce formed plastic components in ISO-certified environments for highly regulated industries.
Hi-Rel Plastics & Molding Corp. is a trusted provider of vacuum forming services for customers across the United States. We produce formed plastic parts such as enclosures, housings, covers, trays, panels, and protective packaging for applications where durability, fit, and cost-effective production matter.
Vacuum forming is a cost-effective way to produce larger plastic parts with a lower tooling investment than injection molding. Backed by ISO 13485, ISO 9001:2015, and AS9100D certifications, we pair forming expertise with rigorous quality systems and in-house secondary operations like CNC machining and assembly.
From prototype through full-scale production, Hi-Rel’s vacuum forming services help customers nationwide bring dependable formed plastic parts to market.

Whether you’re developing a new enclosure, replacing a fabricated part, or searching for reliable vacuum forming services, our team is here to help. Below are answers to common questions about our vacuum forming capabilities and process.
Vacuum forming heats a plastic sheet until it's pliable, draws it over a mold using vacuum pressure, then cools and trims it into a finished part. It's a practical, economical process for larger parts, enclosures, and trays.
Common vacuum formed parts include equipment enclosures, housings, covers, panels, trays, clamshells, and protective packaging for medical, aerospace, industrial, and commercial products.
Vacuum forming works with a range of thermoplastic sheet materials such as ABS, HIPS, PETG, polycarbonate, acrylic, and HDPE. Our team can recommend the right material based on your part's performance, appearance, and regulatory needs.
Vacuum forming typically has lower tooling costs and shorter tooling lead times, making it a strong fit for larger parts and low to medium volumes. Injection molding is better suited for small, highly detailed parts at high volumes. Since we offer both, we can help you choose the right process.
Hi-Rel Plastics is certified to ISO 13485, ISO 9001:2015, and AS9100D, supporting medical, aerospace, defense, and other quality-critical manufacturing programs.
