Pfeifer Industries recognizes that “people buy from people.”  We are determined to always give our customers the highest level of quality and value in the timing belt pulleys we manufacture, the technical services we provide and the mechanical power transmission belting products we distribute.  We strive to produce a timing belt pulley that is of higher quality than our competitors’ without adding additional costs for our customers.  Utilizing over 30 years of design and manufacturing experience, we consider the integration of a part into its final assembly and how the part will perform in its end application.  With our customers in mind, we constantly strive to evaluate our processes for cost savings and efficiencies.

Inspection / Part Marking

Pfeifer Industries is committed to quality. We take enormous pride in maintaining our internal quality requirements on top of the customers’ stated print tolerances/specifications. We frequently go beyond the customer print and examine a part’s function to ensure that the part will fit to its mating part and function as it was intended. To achieve this, we use a variety of inspection tools such as micrometers, gauge pins, calipers, optical comparators, height gauge, and gauge blocks.

To guarantee quality is achieved on every part that we produce, we monitor the following areas of the production process at all times.

  • Constant monitoring of the parts running in the production area
  • Keeping records and samples of each run to ensure consistent flow of quality parts to our customers
  • Every part is marked with Pfeifer Industries or the customer name, part number and serial number
  • Work with customers to keep prints up to date with changes that occur over time
  • Check in all raw materials to ensure they are what were ordered and ready for the production run
  • Inspect the quality of outside subcontractors such as plating, anodizing, and heat treating

NOTE: As a testament to our high standards of quality, a partnership was formed with Mori Seiki to perform beta testing on their HydroGage in machine measuring technology.
