Founded in 1942 Penn Engineering & Manufacturing Corporation is a multi-million dollar U.S. based manufacturer of speciality fasteners. As an established market leader Penn provide fastener and fastener installation design and product solutions worldwide for a diverse range of industries. These specialist industries include electronics, computer, data/telecoms, medical, automotive, marine, aerospace and general manufacturing.

In 2006 their Galway factory decided to integrate its plating operations “in house” in order to improve control of their quality and service issues.

Following thorough market research in Eire, the UK and Europe, in September 2006 Penn Engineering awarded the contract to Jacquet Weston Engineering. An impressive end solution also included an integrated effluent plant, seamlessly delivered through our sister company Puretech Environmental.

The principles of “Best Practice” and IPPC regulations were fully embraced within the plant design incorporating Counterflow Rinsing, Eco Rinses, and Eductor systems.

The plant was a 39 stage Acid Zinc and Zinc Nickel plating line with two additional plating stages for Zinc Tin, Zinc Iron and Tin plate. It coordinates six passivate stages to cater for the multiple seals and lacquers required within the diverse industries Penn operate in.

The plant is based on a standard leading JWE design perfected over many years, modified to comply with the customer’s own individual requirements. It has 16 off 1000mm long motorised Progalvano Barrel Units, three transporters and a two cross transfer systems. The plant was assembled and dry run in our factory prior to shipping and final assembly on site.

The three fully automated transporters are controlled via a sophisticated PLC, the work is loaded into the barrel and the component information entered using a bar code, the barrel in the load/unload stage is located in a load cell, and the bar coded information along with the load weight is used by the PLC to set all of the parameters for that load such as volts, amps, plating times, chemical dosing etc.

Once the load has been processed and automatically unloaded the data for that load with all of the relevant information, process schedule, process times, temperatures, rectifier settings etc is stored in a data base for later retrieval.
