Thermoforming FAQ — Shirley K’s
Frequently Asked Questions — Shirley K’s
CUSTOM THERMOFORMING QUESTIONS
Q: What is thermoforming?
A: Thermoforming is a manufacturing process where a plastic sheet is heated until pliable, then formed over a mold and trimmed to create a finished plastic part. It is commonly used to produce trays, enclosures, covers, and custom plastic components.
Q: How is thermoforming different from injection molding?
A: Thermoforming generally has lower tooling costs and shorter lead times than injection molding, making it better suited for low-to-medium volume production runs. Injection molding can be more cost-effective at very high volumes. See our Thermoforming vs Injection Molding guide
Q: What is the minimum order quantity for custom thermoforming at Shirley K’s?
A: Shirley K’s specializes in short-run thermoforming — typically dozens to hundreds of units per order. Contact us with your specific requirements.
Q: Can Shirley K’s accept a tool transfer from another thermoformer?
A: Yes. Tool transfer is a core capability. Contact us to discuss logistics for your specific tooling situation.
Q: What if I don’t have prints or CAD files for my part?
A: Send us a physical part and we can reverse engineer it — designing and building a new thermoforming tool from the sample.

MATERIAL HANDLING TOTE QUESTIONS
Q: What is a stack-and-nest tote?
A: A stack-and-nest tote is designed to rotate 180 degrees to stack when loaded — and nest inside each other when empty, saving significant floor space when totes are not in use. See our Stack-and-Nest guide
Q: What is the difference between stack-n-nest, cross-stack, and wire bail totes?
A: Stack-n-nest totes rotate 180 degrees to change between stacking and nesting mode. Cross-stack totes rotate 90 degrees to change between stacking and nesting. Wire bail totes change between stacking and nesting by flipping the heavy gauge wire mechanism. See our comparison guide
