For this shop, it’s about more than making parts

Jerry Mullins knows that dozens of Portland, Ore.-area machine shops can make good parts, some with CNC equipment as capable as his own. That’s why his business philosophy, as well as his brother Bill’s, is to differentiate their company by providing high-quality service and a customer experience to match.

There’s an impressive equipment list behind that commitment and a history dating to the mid-1980s when company founder Larry Shodin bought a small turning shop and renamed it Western Precision Products Inc. He soon joined forces with Howard Mullins, owner of a nearby milling shop. They merged their turning and milling competencies. Then in 1995, Shodin sold his share to Howard and retired.

Today, Howard’s sons, Jerry and Bill, own the company. Located in Tualatin, Ore., the shop produces precision components for the aerospace, electronics, power supply and other industries. A building purchased in 2013 boasts 48,000 sq. ft. where about 80 people work. The company also owns and operates two small captive shops located at customer facilities.

Jerry said WPP has always tried to stay ahead of its peers. In 2006, the Mullins boldly invested in a three-machine, 36-pallet NH4000 DCG horizontal machining cell from DMG Mori.

Since then, the Mullins have invested further in DMG equipment, including another NH4000 DCG horizontal machining center (with a six-pallet pool), two five-pallet NHX4000 HMCs, some stand-alone NHX4000 and NHX5000 machines, several DuraVertical vertical machining centers, an NTX 2000SZM integrated mill-turn center and Swiss-style lathes from Citizen and Tsugami.

Some other examples of WPP’s embrace of advanced machining technology include 1,000-psi coolant systems on most machines. Spindle probes are the norm, as well as 4-axis capability, where applicable; large tool magazines; and spindle speeds up to 20,000 rpm.

In October, the Mullins took a step toward Industry 4.0, opening a prototype department with “state-of-the-art technology from top to bottom,” Jerry said. The shop installed a pair of DMU 65 monoBLOCK 5-axis machining centers from DMG Mori, invested in an offline tool presetting system equipped with Balluff-style Bluetooth chip readers and implemented a hyperMILL CAM system from Open Mind Technologies.

“It might be unfair to call it a prototype shop,” Jerry said. “Our emphasis is on rapid turnaround rather than any specific part quantity. If a customer wants to order 20 of something and needs it quickly, that’s fine—assuming it fits within our machine envelope and capabilities.”
