About Us

What we do

Our Story

Fiesta Plastics Inc. first opened its doors in 1988.  Jack Thompson, after working in the plastics industry for over 30 years, traded the title of his truck for a small injection molding machine, with the promise of paying off the balance of the machine or he would return the machine and lose his truck.  Within months the machine was paid off and Jack had purchased 3 more machines.  Now 30 years later Fiesta Plastics has continued to grow.  Our 20,000 sqft facility contains 18 molding machines, and is equipped with a complete tooling/machining facility.   Despite these hard economic times we have enjoyed growth.  With our customers’ needs at the fore front of every decision we have adapted to meet the needs of today's competitive market.

Fiesta Plastics Inc. is not just a molding shop but instead a full service company.  We specialize in designing, manufacturing and delivering a complete and finished product.
