About CW Thomas

environmentally controlled warehouse

CW Thomas was formed in 1946 and has steadily grown to become one of the premier plastics thermoformers in the northeastern United States and beyond.

CW Thomas has extended our brand of quality in manufacturing engineering, mold design and production and superior thermoform plastic manufacturing and assembly to become a highly regarded and respected partner with major product manufacturers. Customers include Fortune 100 industry leaders in the transportation and aerospace sector, the medical and diagnostics industry and providers of precision calibration electronic instrumentation, measurement and testing equipment.

Our strategic plan of partnering with the customer at the initial design phase allows the customer to take advantage of our expertise in both traditional vacuum forming and advanced pressure forming techniques accomplishing the most difficult of applications successfully. The company is certified for both ISO 9001:2008 and AS: 9100C.

In addition to making our molds in house, our engineering staff completes the total value added scenario by closely reviewing each project. This provides possible opportunities to make recommendations for product enhancements that also minimize costs thru manufacturing efficiencies.

Analytic Plastics Acquisition

In July of 2012, CW Thomas acquired Analytic Plastics. Analytic Plastics, Inc., based in Bensalem, PA, is a company with over 40 years of experience in providing a wide variety of products and services for its thermoforming customers.
