Thermoforming Capabilities
Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, formed to a specific shape using a mold, and then trimmed to create a finished product. There are two main categories: thin-gauge thermoforming for packaging (clamshells, blister packs, trays) and heavy-gauge thermoforming for durable parts (vehicle panels, equipment enclosures, medical housings). Vacuum forming and pressure forming are the two primary techniques. Thermoforming offers faster tooling and lower costs than injection molding, making it ideal for medium-volume production and large parts with relatively simple geometries.
±0.010" (±0.25mm) for pressure forming; ±0.020" for vacuum forming
2-6 weeks for tooling; 1-3 weeks for production
$2,000-$25,000 for tooling; $2-$50 per part

Thermoforming in San Diego — FAQ
How many Thermoforming providers are in San Diego, CA?
The San Diego-Chula Vista-Carlsbad metropolitan area has approximately 2,200 manufacturing establishments, many of which offer thermoforming services. The area employs about 48,000 manufacturing workers, ensuring a skilled workforce for your project.
What is the difference between vacuum forming and pressure forming?
Vacuum forming uses suction to pull the heated sheet against the mold. Pressure forming adds positive air pressure (up to 60 PSI) to push the sheet against the mold, resulting in sharper detail, tighter radii, and textures approaching injection-molded quality.
When should I use thermoforming vs. injection molding?
Choose thermoforming for volumes under 5,000-10,000 parts, large parts, or when you need faster tooling. Choose injection molding for high volumes (10,000+), complex geometries requiring detail on both sides, or tight tolerance requirements.
How large of a part can be thermoformed?
Thermoforming can produce very large parts — up to 10+ feet in length. This makes it popular for vehicle body panels, hot tub shells, signage, and large equipment enclosures that would be prohibitively expensive to injection mold.
What industries use thermoforming?
Major users include food packaging (trays, clamshells), medical (device housings, trays), automotive (interior panels, truck bed liners), aerospace (interior panels), and consumer products (appliance housings, point-of-purchase displays).
