What Multiplastics does
Multiplastics is a custom plastics manufacturer founded in 1952 by Robert F. Curd as Curd Enterprises Inc., now operating under second-generation family leadership (President Deborah Herbert since 1992). The company designs and produces heavy gauge thermoformed, pressure formed, twin sheet formed, injection molded, extruded, and CNC-fabricated plastic parts, plus integrated foam components, from a 138,000 square foot ISO 9001-certified facility in Mount Pleasant, South Carolina. Its proprietary TruePart prototyping service produces production-quality parts using actual production materials, and its capabilities span nine vertical end markets including transportation, aerospace/defense, medical, food service, marine, packaging, communications, mechanical/industrial, and concealment/radomes.
The business operates on a quote-based, project-driven model: customers (ranging from major OEMs such as BAE Systems, Bosch, and Hobart to mid-market firms and startups) submit projects online or via direct sales engagement, and Multiplastics' in-house engineering team handles concept design, prototyping, rapid tooling, production, and value-added assembly. Revenue is generated primarily through one-time custom manufacturing services, with no disclosed recurring subscription, licensing, or tiered pricing model. Notable proprietary offerings include a worldwide-marketed plastic buoy line and engineered products such as Caroline's Cart (developed with Technibilt) and the first U.S. bridge water runoff containment system.
The company's go-to-market is sales-led and engineering-driven, relying on its website, case studies, limited social media (LinkedIn, Facebook), and earned media coverage rather than paid acquisition. Marketing emphasizes the company's 70+ year track record, FST-compliant aerospace capabilities, and metal-to-plastic conversion expertise. Multiplastics holds a registered trademark and ISO 9001 certification (since 1997), but has no disclosed external funding, public listing, or parent company; it remains a privately held, family-operated custom manufacturer with a stated regional identity as 'the leading plastics manufacturer in the southeast.'

Products and services
- Thermoforming & Vacuum Forming Heavy gauge thermoforming and vacuum forming of custom plastic parts with tight tolerances and sharp detail. The process heats thermoplastic sheet until soft, then stretches it over mold contours using vacuum pressure. Part thickness ranges from .060 to .50 inches, offering cost-effective tooling flexibility and quick production compared to injection molding.
- Pressure Forming Advanced forming process that uses compressed air to force hot plastic sheets against a mold, achieving detail five times greater than traditional vacuum forming. Ideal for fine detail, textured surfaces, engraved lettering, and wood grain finishes, with quality similar to injection molding at lower tooling costs.
- Twin Sheet Forming Thermoforming process that simultaneously forms two sheets from separate molds to create hollow, double-walled parts with high structural integrity, rigidity, and low weight. Allows internal reinforcements such as rigid foam, wood, or metal.

- Placon Corporation: Thermoforming manufacturer with custom and stock product lines serving medical, food, retail, and industrial markets. Comparable as a thermoforming peer with multi-vertical exposure and in-house design/tooling capabilities.
- Creative Plastics International: Custom heavy-gauge thermoformer producing parts for industrial, medical, transportation, and aerospace markets. Directly comparable on heavy-gauge thermoforming specialization and custom contract manufacturing model.
- King Plastic Corporation: Manufacturer of polymer sheets, slabs, and fabricated plastic parts for marine, industrial, architectural, and food processing markets. Comparable on custom plastic product manufacturing across industrial and marine verticals.
- Wilbert Plastic Services: Custom thermoforming and injection molding services with a strong automotive vertical (Toyota supplier). Comparable on multi-technique offering (thermoforming + injection molding) and transportation end-market exposure.
Broad incumbents
- Röchling Engineering Plastics: International manufacturer of semi-finished and finished engineered plastic products for industrial, medical, and transportation markets. Comparable in serving transportation, medical, and industrial verticals with custom plastic components, but at significantly larger scale and global footprint.
- Klöckner Pentaplast: Global manufacturer of rigid and flexible plastic films and formed packaging. Overlaps with Multiplastics' thermoforming and packaging-adjacent capabilities as a much larger incumbent with broader geographic and product footprint.
- Spartech (Avient): Large diversified plastics manufacturer (now part of Avient) offering custom sheet, thermoformed packaging, and engineered materials. Broader incumbent that overlaps with Multiplastics' thermoforming and extrusion offerings but at much greater scale and portfolio breadth.
