Custom Plastic Injection Molding & Design Since 1969
Proto Plastics was formed in 1969 as a plastic injection molder and mold builder serving a small group of customers in the business equipment market. Today, we are a full-service contract manufacturer of custom plastic injection molded parts and assemblies, specializing in technically demanding, close tolerance parts required in a wide variety of industries.
We can be successful only by earning the trust and loyalty of every customer we serve. This we achieve through excellence in collaborative engineering, quick response to customer needs, constant dedication to superior product quality, keeping our delivery promises, and total honesty and professional integrity in every customer interaction.
Our 65,000 sq. ft. building just north of Dayton, Ohio, includes all engineering, tooling, injection molding, and assembly activities, as well as warehousing for finished goods and purchased assembly parts. Part and mold design along with plant operations are supported by leading edge CAD/CAM and process control software, resulting in compressed lead times and extraordinary flexibility in meeting your daily requirements.
We know our business. The managers and supervisors have an average tenure with the company of 19 years, providing exceptional leadership continuity and injection molding know-how. Many of our employees have been with us for more than 20 years. To you, this means “right-the-first-time” plastic component and tool design, production, assembly and delivery.
Consistent product quality is paramount to our success, and we believe our ISO-9001:2015 certified Quality Management system is second to none. Inspection and testing are a never-ending process, procedures and documentation are firmly established, and every employee is honestly committed to pursuing perfection.
