WHAT IS HEAVY GAUGE THERMOFORMING?
Heavy-gauge thermoforming uses thicker plastic sheet material to produce rigid, structural plastic parts — as opposed to thin-gauge thermoforming used for disposable packaging. Heavy-gauge parts are typically stronger, thicker, and designed for repeated use or long service life.
Typical applications: industrial trays, enclosures and covers, OEM equipment components, returnable dunnage, large structural plastic parts.
SHIRLEY K’S HEAVY-GAUGE CAPABILITIES
- Short-run specialization: dozens to hundreds of units per order
- In-house CNC trimming: precision trimming and hole locations to mate up with other components
- Tool transfer: receive your existing heavy-gauge tool and resume production. Ideal for aftermarket parts manufacturing.
- Reverse engineering: build a new tool from a physical part sample
- Productive rotary equipment for large runs (thousands per order)
- Materials: HDPE, ABS, HIPS, PETG, Kydex, Acrylic, and PC
- Part thickness gauge range from 0.080″ to 0.450″
