As part of our mission to be the World Leader in Product Protection, StockCap has invested heavily in the thermoforming process. This process not only allows us to manufacture clear plastic caps and covers, but it expands our ability to create custom, “product protection” solutions like shipping trays and thermoformed inserts.
What is Thermoforming?
Thermoforming is a process of heating thermoplastic sheet and placing it over a mold until cooled. The thickness of the material determines whether the manufacturing process uses rolled sheets (thin gauge) or pre-cut stacked sheets (thick or heavy gauge). Thin gauge material is dominant in the disposable packaging sector, especially in the retail markets. Heavy or thick gauge material is commonly used as permanent components in such things as refrigerators, automobiles and spas to name a few. PVC is the most commonly used material in any thermoforming production.
All StockCap thermoforming products are manufactured in the USA.
Thin Gauge Thermoforming
StockCap manufactures a wide variety of thermoformed solutions that are ideal for nearly any product line. Aside the popular clear plastic clamshells and blister packaging, thermoformed trays and inserts for industrial uses is our niche. These are typically high volume, custom designed trays, often reusable.
Heavy Gauge Thermoforming
Heavy gauge thermoformed products need to be sturdy and are typically larger parts. Volume requirements are frequently much smaller than a thin gauge part. Heavy gauge parts are designed to exist for very long periods of time. StockCap produces strong durable parts with excellent strength to weight ratio.
