Plastic Knob Manufacturer 

Custom knobs are widely used as a part of controlling and adjusting aspects of the equipment. DimcoGray, a thermoplastic custom knob manufacturer, has been producing industrial and commercial plastic knobs for more than 95 years. Due to constant use under sometimes rugged conditions, they are subject to wear and tear.

At DimcoGray we realize that sometimes a custom knob can be a small and insignificant part of a machine. However, the knob can have a significant sizeable impact on the functionality of a vital piece of equipment. Custom plastic knobs provide the apparatus that accommodates human and machine interaction and are a very important part of your equipment.
