MANUFACTURING CASE STUDY
A
Problem:
Legacy Method Lubrication Point
An agricultural equipment company was using tube connectors, tubing, and a grease fitting to provide a service location to a recessed bearing. The recess exceeded the total length of commercially available grease fittings, and the legacy design was complicated to users. In addition, the legacy design was unreliable in an outdoor environment.
B
C
Clear Tubing
Tube Connector
Opportunity: A solid design sufficiently robust to allow deep seated installation and exterior wear and tear was required. The ability to change out faulty or contaminated parts was also considered; provided that there was sufficient seal to allow “flow through” of grease from a grease gun down into the bearing.
D
E
Redesigned Method Interchangeable Grease Fitting Robust Extension
Solution: The Huyett manufacturing team designed a thick walled extension with tapered male threads to provide a “pilot” into the recessed hole. The tapered threads were designed to provide a dry seal, as well as to mate into the female threads on the other end. In addition, a mating deep seated “socket” was designed for a more automated assembly. It allowed interchangeable parts for repair and replacement. Special production processes were used to make the longer shanked part straight and true. The final design provided better reliability, simpler and more robust design and interchangeability at slightly less than legacy costs.

MANUFACTURING CASE STUDY
A
Legacy Method
Problem: Engineers were looking to identify cost savings in an “end-stop key.” The key slid back and forth in a channel, with a pin serving as a “stop.” The legacy part consisted of a stainless steel key, partially drilled, with a grooved pin on one end.
Precision Drilled Hole
B
Opportunity:
C
Dowel pins are more expensive to produce than alternate designs such as a rolled pin. Rolled pins have a less precise outside diameter than many dowel pins. Orientation may be required of the rolled pin, which can complicate installation. A “Type H” grooved pin was the best solid pin application because it required a less precise hole than a dowel pin, and the grooved end provided a more sturdy grip.
Shaft Key
D Type H Grooved Pin
E
An alternate design and build strategy was considered. Die-casting provided sufficiently precise dimensions, with a solid stopping mechanism. With die-casting, there was no pin installation cost, and overall design was more Consistent. In addition, there was no need for operator intervention in pin depth and placement.

Solution: Rolled Pin
G

Redesigned Method
H
Using Huyett engineering and global sourcing, a die-casting contractor was located. Low tooling and setup costs, coupled with the installation and production cost advantages over multiple-piece designs yielded an acceptable part at a fraction of the legacy cost. Overall, the customer’s goal of cost reduction was exceeded by a wide margin.

MANUFACTURING CASE STUDY
A
Problem:
B
C
A square handle used on electrical boxes required a radiused edge to ease installation, and had a precise effective length between grooves to ensure a tight fit. Because the part was square shaped, a lot of “chatter” is created during production by the “interrupted cut” during turning. The edges of the material “beat” on the tool until penetrated and turned smooth. This “chatter” impairs accuracy and thus machine time must be increased as spindle speed is reduced.
Precision HOle Positioning
Opportunity:
D
Conventional Cold-Draw
Huyett’s global sourcing team was able to locate profile mills to make raw material with pre-radiused edges. The raw steel was specified to precise lengths to reduce waste on the chucked end.
E
Profiled Draw
Solution:
F
G
Reduction in Waste
The radiused raw stock reduced “chatter” and allowed spindle speed to be increased. Machine time is reduced by higher throughput, as well as the elimination of the radius as a turned operation. Scrap was reduced by 12% by coordinating raw material length to consumption and production setups. In addition, a test electrical box assembly was deployed as a “go-no-go” gauge to ensure perfect groove width accuracy.

MANUFACTURING CASE STUDY
A
Precision Hole Positioning
Chamfered Edge
B Radial Ends
C Holes Positioned and Aligned within 0.005"
Problem: A power transmission customer was using a precision drilled machine key as a positioning reference in an important mechanical application. The three holes in the part possessed highly precise tolerances for alignment and positioning. The legacy manufacturing method yielded high scrap rates and setup costs. This was due to the accumulated manufacturing tolerances inherent in the conventional process.
Opportunity: D
Huyett has proprietary air-over hydraulic milling fixtures that are seated on pallets. The air-over hydraulic design provides high rigidity, clamping power, and throughput. The throughput is increased because the operator loads parts while the machining center operates.

Using an oversized blank part, the Huyett manufacturing team designed production to run on the air-over hydraulic fixtures. The entire key is formed and drilled from a solid piece, turned over, and in a second pass, the bottom is removed. The rigid one-piece production design and two-part production operation resulted in cost savings of 56%.

MANUFACTURING CASE STUDY

Original Design Problem:

Pull Ring
A few years ago, a medical supply company approached us with a challenge to create a ring pull pin with a threaded shaft. Our sales team and engineers worked with the company to develop a cost-effective solution. Recently, they came back to us with a need for a locking mechanism that would allow them to keep the pin in an open position. They only needed a small quantity, and they needed them as quickly as possible.
Threaded shaft to stabilize Locking pin
Opportunity: D
E
F
Along with our customer, the Huyett manufacturing team worked quickly to develop several potential solutions. One was a costly, time-consuming side pin that would serve their needs, but wasn’t an affordable option. Another was a notched pin that could be locked, but was not a viable solution since clearance was too tight to allow the shaft of the pin to slide into a locked position. A third solution provided a cost-effective, custom manufactured, hexshaped locking collar that could be quickly added to or removed from the original pin.
Redesigned Method
Hex Collar
Set Screw
Solution:
G
H
A corrosion resistant hex shaft was used to create collars for the locking pins. After the shaft was cut to length, each collar was turned, threaded, finished, and combined with the existing ring pull pin. The finished assembly allowed the ring pin to be pulled, twisted, and locked in an open position. Additionally, a hole was threaded in one side of the collar so that a set screw could be added to the assembly to safely lock the ring pin in an open or closed position.

Redesigned Method
A manufacturer of RV rooftop air conditioners requested engineering assistance in perfecting a confined-space sheet metal application. In the application, a bolt needed to be retained into a small corner in the interior of the air conditioning unit. The bolt retained an exterior shroud that needed to be removed during servicing.

SOLUTION: Huyett’s engineering support team recommended a pinch-release bolt retainer manufactured by A Raymond Tinnerman. The pinch-release yielded hand-held application so no tools would be required in the confined installation area. As the pinchrelease retainer is visually-descriptive in design, its utility is intuitive and quite simple. Huyett sales managers facilitated design and procurement through a Huyett authorized distributor so that procurement of the part could be integrated into other fasteners spending by the manufacturer, and marketing channel integrity could be maintained.
Step #2 Apply slight finger pressure on the opposing wings and slide nut over threaded stud
RESULTS: Step #3 Rotate SPEED NUT 1/2 turn to lock on screw
In summary this was a win for all. A Raymond Tinnerman gained a new application; the RV products manufacturer conquered a complicated engineering challenge; and the fastener distributor gained a new customer.
