To help reduce costs for wire formed parts, H.E. Orr buys raw materials directly from steel mills rather than in precut bars. This way there is no middle man to add an additional markup and inflate the price for finished parts.

This also allows Orr to draw the wire down to the exact specifications needed—keeping a tighter control on tolerances and quality. For example, a coil of plain carbon steel comes in at twenty-nine sixty-fourths (29/64") of an inch, and specifications might require drawing down to 10mm with only a + or - .03125" tolerance.

Originally, cold forming was known as cold heading. Cold forming was a common way to make the heads of screws and bolts. After forming the head, the threads would be cut or rolled into the material. The advantage was the parts could be made quickly with little or no scrap.

H.E. Orr Company uses cold forming machines to make simple and complex shapes for a wide variety of applications. Orr's tooling is designed to extrude the material to (.004") of an inch tolerance. Then a series of punch presses shape the part to customer specifications. The number of punch presses is determined by the specifications of the parts produced.

The coating business is all about meeting customer specifications and consistently delivering quality parts on time. Part of the process is testing to ensure that every part that comes off the line meets quality standards.

Every product gets extensive testing to make sure that it meets customer requirements. The most common test is the salt spray test. In this test, coating samples are collected on 3" x 9" plates. The plates are run through the coating line at the same time as customer parts. This ensures that the test plates are coated in the same manner as the parts.

H.E. Orr Company’s production line has a 4' x 6' window. Orr can accommodate any part that will fit in this space. Orr also has the added advantage of dual drives on the line that allow it to handle heavier parts than what many e-coaters can accept. If have been told your parts are too heavy for a particular production line, it makes sense to call H.E. Orr as we can typically handle what many coaters cannot.
