Our Revolutionary Epoxy Molding System Fast, Stable and Flame Resistant
Vpoxy is a proprietary epoxy molding system designed for very fast molding cycles and excellent shelf stability. This revolutionary system requires low transfer pressures to achieve optimum cavity fill, while providing excellent moisture protection and leadwire adhesion.
The material is a soft-flow, mineral-filled, fiberglass-reinforced epoxy molding compound that meets the UL 94 V-0 flammability rating. It is designed for use in both transfer and screw injection molding equipment.
Vpoxy exhibits exceptional shelf stability while maintaining a rapid curing process and is considerably less abrasive than ordinary silica-filled materials.

OUR CAPABILITIES
COIL WINDING
Coil winding is where it all began for PeterPaul back in 1947. In 1972, our strategy shifted, and coil winding operations were relocated from New Britain, Connecticut, to Fajardo, Puerto Rico. We offer a wide range of coil winding capabilities to meet the diverse needs of our customers. Our experienced in-house team can design custom processes and provide the tooling required for any application that fits within our capabilities.
Let us quote your needs and see if we can help you reduce costs on your coil windings while you concentrate on your core businesses.
METAL STAMPING
At PeterPaul, bringing metal stamping for many of our coil components in-house was a strategic investment that delivered both cost efficiency and quality. Over the years, this commitment has evolved into deep expertise in precision metal stamping, along with advanced die design and construction — all engineered and manufactured under one roof. From housings and yokes to brackets, washers, plates, terminals, and highly specialized, application-specific components, our team produces critical parts with consistent performance. Our progression die was designed and built entirely in-house using the latest tool design technologies.
THERMOPLASTIC MOLDING
Thermoplastic Insert molding. Our plant was ahead of its time back in 1972, thanks to a pioneering effort by our founders. Leveraging our innovation, knowledge, and relationships, we have worked very closely with makers of Thermosets since the 1960’s and developed the best compounds for their needs. The roots of those relationships can be seen right here in our plant, rooted in a profound knowledge of formulation and compounding capabilities. Inquire about our compounds. On the other hand, we have pioneered processes in the Thermoplastic arena. Peter Paul Electric, Inc. has been working with these materials for many years, including close cooperation with DuPont.
PLASTIC VALVES
Our solenoid-operated valves are designed using Rynite® PET thermoplastic polyester resin and Delrin® acetal resin. The solenoid assembly is encapsulated in Rynite® PET thermoplastic polyester resin rather than epoxy. The coil bobbin is injection molded from Rynite® PET or, for valves installed in food or beverage equipment, from Delrin® acetal resin. The valve body, formerly machined from brass, stainless steel, or aluminum, is now injection-molded from Delrin®.
Customers benefit from lower manufacturing costs, the switch from potted epoxy to Rynite® PET for encapsulation sped production, avoided VOC emissions, eliminated secondary finishing, and allowed integration of a mounting bracket in the design and elimination of a costly welded metal assembly for plunger guiding. PeterPaul valves have the proven durability you rely on and have been tested for 20 million open-close cycles without failure. PeterPaul saved time and money in meeting UL 1446 Class F (155ºC) requirements by using a preapproved, pretested DuPont electrical insulation system (EIS).
Solenoid encapsulation: Rynite® 415 HP. Bobbin: Rynite® FR530. Both meet needs for strength, stiffness, high productivity in injection molding, and UL1446 Class F listing.
Valve body and bobbin: Delrin®500 BK642. This material fulfills requirements for strength, stiffness, and suitability for use in food and beverage equipment.

ABOUT US
Peter Paul Electric, Inc. has been manufacturing coils in Fajardo, Puerto Rico, since 1972. Our history extends back to 1947 with the founding of Peter Paul Coil Company in New Britain, Connecticut. Over the years, we have developed broad experiences across several manufacturing disciplines and approach each project with a practical, solutions-focused mindset. We believe that maintaining control over key processes helps ensure consistent quality and reliable performance. For this reason, we have established a range of in-house capabilities that begin with tool design, construction, and maintenance. We design, build, and maintain our plastic molds and metal stamping dies in-house, recognizing that part quality depends heavily on tooling quality. Our capabilities include coil winding, assembly operations, metal stamping, and a wide range of plastics molding solutions.
With more than 50 years of experience in insert and bobbin molding, our team supports both thermoset and thermoplastic applications. Our plastics services include bobbin molding, high-precision parts molding, and high-precision insert molding. Our experience with thermoset materials has also enabled us to develop our own molding compounds, while continuing to support thermoplastic applications to meet a variety of customer needs.
We welcome the opportunity to discuss your project requirements.
