Plastic Injection Molding & Tool Building since 1946!
Crescent Industries is an employee-owned, injection molding company providing an integrated, single-source solution for your custom plastic injection molded components. Our advanced engineering capabilities are at the core of all processes. Crescent’s capabilities allow us to mold a comprehensive range of engineered and commodity grade resins. We currently serve the medical, pharmaceutical, dental, defense, safety, electrical/electronic, aerospace and OEM/Industrial markets.
As a plastic injection molding manufacturer, we utilize multiple facilities designed for various applications to provide customers with an integrated single-source solution. In addition to our state-of-the-art, highly-automated manufacturing facilities, we’re equipped with both horizontal & vertical/vertical injection molding presses ranging from 35 to 385 clamping tons with shot sizes from .25 to 42.4 ounces.
Our engineers are trained in The Scientific Approach to Injection Molding and are certified by RJG & the Global Standards for Plastic Certification. We establish robust processes utilizing scientific injection molding principles and decoupled II and decoupled III molding. We have a complete tool-room for all your needs and offer complex & high-precision Swiss-screw machined components & production machined components. In order to complete your project and solve complex production issues, we also offer several value-added-services that can be performed within our ISO 7 or ISO 8 Clean Room environments.
Part Design Guidelines
The “Injection Molded Part Design Guidelines” will review items to consider when designing your next plastic component like:
- Maintaining uniform wall thickness to minimize sinking, warping and improve mold fill.
- Using generous radius at all corners to avoid sharp corners that increase stress concentration which can lead to part failure.
- Incorporating sufficient draft angles for easy removal of the part from the mold.
- Using ribs or gussets to improve part stiffness.
Mold Design Guidelines
Crescent Industries’ mold design engineers look at the aspects of the part that are important for injection molding. Through adherence to these design principles and best practices at the beginning of the design process will ultimately lead to better overall quality of parts during manufacturing. These “Mold Design Guidelines” will evaluate items like the follow:
- Gate Designs / Runner Designs
- Cooling / Venting
- Mold Filling

Swiss Screw Machining
Our best in class high-precision Swiss-Screw machined component capabilities can be used as either a finished product or as inserts for the injection molding process, allowing us to help you consolidate your supply chain.
Bar stocks (up to 3″)
Our ERP system (IQMS) gives us the ability to provide a customer portal capability which reports in real-time. This gives our customers the ability to view the status of their project at any given time. Customers may place orders, view product availability, check on order status and shipping status, view production information plus run customer specific reports.
Offering KANBAN shipping of stocked inventory and Just-In-Time Delivery from blanket orders to delivering your parts as you need them which is all tracked and managed through our ERP system. We have our own delivery trucks, so we offer a no charge for regular scheduled deliveries within a 100 mile radius.
To be your committed manufacturing solution, our team can support every aspect of your custom injection molding and business needs. Our Project Management Office (PMO) manages new mold builds, tool transfers, and new projects. They examine the entire scope of your project, timeline & cost management, material selection, design & development and overall integration with your engineering team.
Essentially, you receive a dedicated team of professionals that collaborates, communicates, coordinates and executes. In addition, we have dedicated R&D injection molding machines to aid in initial sampling and validation to accelerate all phases of your project and transition into full production.
