At Stelray, we take pride in offering a seamless mold transfer service that directly translates into saving companies valuable resources and time. Our expertise in handling complex transitions ensures that businesses can smoothly transfer molds, even in the aftermath of fractured business relationships. Our streamlined process minimizes transition periods, allowing for swift integration and resumption of manufacturing operations. We understand the importance of maintaining product quality and specifications throughout the transfer. Stelray’s full service in-house tool room allows for the ability to quickly address anticipated or unexpected mold adjustment needs. We strive to not only bridge the gap caused by strained partnerships but also to provide a pathway to enhanced efficiency and renewed focus on core business objectives.

Heat-and-cool molding is characterized by rapid heating of the mold, prior to the injection of the resin, to a temperature above the heat distortion temperature of the resin. Injection to the preheated mold drastically improves the flow properties of the resin, resulting in the creation of high surface quality products with almost unidentifiably faint weld lines. In the subsequent cooling stage, the mold is cooled rapidly to a temperature below the thermal distortion temperature. The precipitate solidification has the effect of eliminating weld lines and flow marks, and also offers such merits as reduction of warps and sinks, shortening of cycle time, and elimination of dimensional errors.

Our white room molding capabilities find application in various industries, including healthcare, oral care, electronics, and other sectors where maintaining a controlled environment is required. From intricate medical device components to precision electronics, we ensure that our white room molding meets the stringent standards demanded by your industry.

Stelray offers complete custom injection mold-making services as well as accepting mold transfers of existing tooling all managed by our expert engineering team, who will work with you to achieve optimum performance and cost-effective savings. As part of our service, we offer in-house design and long-term mold service maintenance, as well as on-site tool room resources for mold enhancements or new product needs.

As a full-service company, we offer in-house design, tooling and engineering support as part of our custom mold-making services. All tooling design and manufacture is done by our team—for a complete custom application. Our engineering staff and molding technicians are experienced in commodity, engineering, and exotic, high temperature resins, to assist you in the proper plastic resin selection while developing the mold best suited to take on the material selected for your project.

We have an outstanding supplier record of providing precision plastic molding, post-molding and prototyping services to an array of industries and Fortune 500 companies. We take pride in knowing that our customers rely on our team for consistent quality, superior plastic injection molding service and on-time delivery. Our facility is fully prepared for large part injection molding, ensuring precision and efficiency at scale.

At Stelray, we offer a range of post-molding value-added services for our customers that require more than just a molded part. Pad-printing, hot stamping, painting, plating and shielding services are available for decorating and coating requirements. In addition, ultrasonic welding, and heat-staking resources are available to accommodate your molded joining needs. If your program requires packaging or assembly, we offer bagging options to complete full-service packaging services.

At Stelray, we are often asked to assist in the plastic part design development and prototyping of new product ideas for our customers. If “speed to market” is your concern, Stelray’s in-house 3D printing services can be the solution, or consider the development of a quick turn soft tool constructed in our in-house tool room. As a full-service plastic injection molding company, we offer a number of product design and engineering services to help develop form, fit and function of your part for successful plastic injection molding.

Stelray Plastic Products is a leading global custom plastic injection molding company providing cost-effective solutions across a wide range of applications and industries.

Our specialty production shop is equipped to take on short, mid and large-volume runs, and offers white room services for medical, dental and bioscience applications. Among our capabilities:

Kaken Geneqs' hot/cool thermal cycling (weldless molding) machine is a hybrid injection molding system that delivers both gas assist and heat-and-cool molding capabilities in one convenient package. It is a multi-functional piece of injection support equipment that delivers gas injection molding, gas press molding, and heat-and-cool molding, as well as any combination thereof. (Other equipment available by request: dedicated heat-and-cool, pressurized water, and rapid heating/cooling mold equipment.) The system accommodates a variety of needs from customers including product quality improvement, lower cost of molding, and novelty in design.

Our creative approach to streamlined manufacturing and problem-solving allows us to manufacture high-quality complex components and assemblies economically. Our Quality Management System incorporates the principles of ISO-9001:2015, with a comprehensive plan and system of procedures in our daily tasks and for every production run. Every new project at Stelray begins with a comprehensive Program Review which includes a deep dive into the inspection requirements for the given components to ensure that we understand your product quality needs from the beginning. Additional services offered at Stelray Plastic Products through our QA Department include complete Product Validation, Process Capability Studies and PPAP investigations.

At Stelray Plastic Products, Inc., we take pride in our advanced manufacturing capabilities, including our separated white room molding cell. Our commitment to precision and quality extends to every aspect of our production process, and our white room molding is no exception. This room caters to healthcare components that necessitate a more controlled environment than a standard production room, but where an ISO standard clean room is not required. This will enable our partners to get their precision parts manufactured with the necessary cleanliness and attention to detail, all without the heightened costs typically associated with clean room facilities.
