Plastic Profiles Plastic Tubes Plastic Sheet Thermoforming
Extruded plastic profiles ranging from simple U channels to precision, custom engineered extrusions are the backbone of Seiler Plastics.   Extruded plastic tubes are one of our specialties at Seiler Plastics. SPC can extrude tubes from a wide range of plastic materials into many sizes.   SPC possesses the ability to both extrude plastic sheet and convert it into finished products by die cutting, slitting, and rolling the sheet. This is what makes Seiler Plastics stand apart from the competition.   SPC utilizes both rotary
and single station thermoforming machines
to ensure you are provided
a quality part.
