Plastic Products, Inc.

As an industry leading custom manufacturer, at Plastic Products, Inc. we are often called on by customers to lend expertise in the early stages of product development. The ring seal in each of the components shown here is a small seat that is used by a customer in the aerospace industry. The customer contacted us to create this experimental part for them out of a 15% polyimide PTFE material. The seat has an outer diameter of 0.75", an inner diameter of 0.735', and a length of 0.2". The part was turned on a CNC Hardinge lathe to geometric tolerances of 0.0005" for the outer diameter and 0.001" for the inner diameter, according to ANSI Y14.5 and customer specifications. We made eight of these prototypes for the customer, with a turnaround time of 2 days.During testing, the customer concluded that the 15% polyimide filled PTFE material was not suitable for their application. In search of an alternate material, the customer asked for our opinion regarding the optimal material, among LDPE, PTFE, Dyneon TFM 1700 PTFE, HDPE, and UHMWPE. However, because the customer could not provide sufficient details regarding the application, we did not feel it was prudent to recommend a single material. Instead, samples were produced from all of these materials, allowing the customer to perform further testing in order to accurately determine the most suitable material choice. Samples were provided for testing within two weeks, preventing costly delays in the development process. For additional details regarding this custom machining and development project,

At Plastic Products, Inc., we are established experts at standard and advanced machining of plastics. We operate an ISO 9001:2008 certified facility that provides cutting edge quality and production capacity made possible by our CNC machining capabilities and an internal emphasis on precision and accuracy. Operating in a 20, 000 sq. ft. facility that integrates Six Sigma and Lean manufacturing principles, we are able to meet the demands of the most complex requirements.Our investment into automated manufacturing allows us to deliver a greater range of machining processes without sacrificing efficiency or quality. We offer traditional processes including milling, turning, drilling, boring, threading, countersinking, and facing, as well as processes such as gear hobbing, knurling, profiling, thread milling, spline cutting, and others. We operate CNC and manually controlled machines that can turn and mill Vespel, Delrin, Nylon, PTFE, Torlon, and much more, and feature three to four movement axis. Our precision lathes can accommodate workpieces up to 8" long and 116" to 12" in diameter, while our mills can work parts up to 15" wide by 20" long and 16" high, all to 0.0005" tolerances.In addition to plastics machining, we also work with approved vendors for such services as anodizing, grinding, heat treatment, passivation, CAD design & consulting, and extensive quality inspection. We presently accept orders ranging in size from small to medium quantities and support short run contracts. Plastic Products can also use its experience in prototyping and research & development for new product design. We complete orders with four to six week lead times on average, with additional expedite services available.
