We place a high demand on client retention. We understand how difficult customers are to find within the injection molding industry, and how important they are to keep. We strive to go above what's required to make sure our clients know we value their business.

A trusted plastic part manufacturer such as Pioneer Plastics, has in house engineers that can take your concept from start to finish. We will help design the custom plastic part and produce a prototype before we build the mold and start production.

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.

Determining if injection molding is the right process for a custom plastic part depends on several factors, including the size and complexity of the part, the required material properties, and the production volume needed.

Choosing the right custom plastic part manufacturer requires careful consideration of various factors. Here are a few key things to keep in mind:

Production volume: Injection molding is most cost-effective at high volumes due to the initial tooling costs required to create the mold. If you only need a small quantity of parts, another manufacturing process may be more appropriate.

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.

Tolerance requirements: Injection molding can achieve very tight tolerances and high precision in part dimensions, making it ideal for applications where accuracy is critical.

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.

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.

While both injection molding and 3D printing are popular manufacturing methods, each has its own unique advantages. Injection molding can produce complex plastic parts with incredible structural strength unlike 3D printing. Injection molding also allows for a wider range of engineering grade plastics.

Our Sales and Engineering teams have over 175 years of combined expertise in project management and plastic part manufacturing.

The cost of injection molds can range from $10,000 to over $100,000, depending on the size and complexity of the mold. If you only need a small quantity of custom plastic parts, say 1,000 pieces or less, investing in an injection mold may not be the most cost-effective solution for your manufacturing needs.

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

Custom injection molding involves significant up-front costs, typically ranging from $10,000 to $250,000, influenced by the size and complexity of the mold. If your project involves producing 1,000 units or fewer, alternative manufacturing methods may be more cost-effective.

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.

The custom injection molding process starts with a conceptualized design and ends with a uniquely manufactured product.  If your product needs to be aesthetically pleasing

Pricing: Compare pricing from different manufacturers to ensure you are getting a fair price for your custom plastic parts.

The time required to build a new mold for a custom plastic part can vary significantly based on factors such as the part’s complexity, the number of cavities and parts in the mold, as well as its size. Typically, this process can take anywhere from 2 to 26 weeks.

Bringing your production back to the United States through re-shoring provides you with greater control over your manufacturing process. Global events in recent times have made supply chains across the world unpredictable and unreliable.

Material properties: Injection molding works well with a wide range of thermoplastic materials, but not all materials are suitable for this process.

Quality: Ensure that the manufacturer has a reputation for delivering high-quality products that meet your specifications.

The modern manufacturing world is full of options for businesses like yours to create products and components. It can be overwhelming if you don’t understand

Plastic injection molding is a manufacturing process used to produce large quantities of plastic parts with high precision and consistency. The process involves melting plastic pellets, also known as resin, then injecting the molten material into a mold under high pressure. After the melted resin is allowed to cool and harden in the mold, the custom plastic part is ejected then inspected.

We take that mold and use plastic injection to produce your plastic products. In the molding process, injection molding machines force liquid resin into the mold cavity to form the part. Pioneer currently operates 25 modern plastic injection molding machines ranging from 75-ton to 1200-ton clamp force.

Our industry experts are more than capable of educating you on the design and manufacturing process so that you feel comfortable making the decision to move forward with custom injection molding.

With a geographically centrally-located headquarters, we ship your finalized plastic products directly to your consumers and retail partners. Our 50,000+ square foot production and distribution facility is located in the heart of the Midwest, just a few hours from Indianapolis, St. Louis, Louisville, and Nashville. We have excellent access to all major transportation networks, allowing us to ship your custom plastic parts efficiently.

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.
