Whether it’s a simple product design or a complex assembly using our internal robotics and hand-assembly, we have the capabilities to fit your requirements and your supply chain expectations.
The Scientific Approach
Utilizing our Scientific Injection Molding Principles, SPC and state-of-the-art Injection Molding Machines, our focus is to provide our customers with a robust process to produce the highest level of quality for our components and devices. This begins in the early stages in our Design For Manufacturability (DFM), through our qualification and Decoupled Molding process and optimized using our in-process inspection criteria with high-end measurement equipment.

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
We utilize Baxter, Sawyer and Universal robots to perform highly specific actions with an extremely high degree of accuracy. Our in-house dedicated automation team focuses on programming our robots to achieve increase throughput and cost savings.
We offer a variety of options that are available to industrial robots and automation customized to match the product being handled and can perform a variety of manufacturing tasks. These task require use of vacuum cups, grippers, nippers, sprue pickers and sensors.
Automated Work Cells
We utilize cellular manufacturing to perform a variety of multi-task functions within a given work space. This minimizes the hands-on involvement in the overall project and are designed by our in-house automation team working in conjunction with outsourced partners as needed.

In-House Tooling Capabilities
We specialize in building new tooling along with comprehensive maintenance, repairs, and revisions of existing tools. Our journeymen mold builders produce injection molds that provide cavity-to-cavity consistency and repeatability by utilizing high-speed CNC mills, die-sink EDM, and wire-sink EDM. Our capabilities extend from single cavity open and close tools to complex 96 cavity tools with multiple actions, always following the SPI 101-103 mold classifications.
Our cost-saving solutions for new tooling projects provides a competitive advantage over suppliers that don’t have in-house tooling capabilities.
MUD (Master Unit Die): The choice when a “dedicated or stand alone” mold base is not required. The part, runner and gate geometry are cut into standardized inserts that fit into the frame.
Hot Runner System: An assembly of heated components used to inject molten plastic into the cavities of the mold
Unscrewing Molds: Used when there is a requirement for male or female threads on a plastic component
Action Molds: Includes mechanical action incorporated into the design when a hole, slot, undercut or thread is needed that is not perpendicular to the parting line
Two Plate Molds: Provides one parting line and the mold splits into two halves; the sprue, runners, gates and cavities are all on the same side
Three Plate Molds: These molds will have two parting lines and are used because of their flexibility in gating location
Insert Molding reduces assembly and labor costs, reduces the size and weight of the part, improves component reliability and delivers improved part strength and structure with enhanced design flexibility by incorporating metal and plastics or multiple combinations of materials and components into a single part. The process makes use of engineering plastics for improved wear resistance, tensile strength and weight reduction as well as using metallic materials for strength and conductivity.
Inserts can be molded into a diverse range of critical plastic components. These components can be used in housings, instruments, knobs and electrical components. Which can be utilized in the medical, defense, aerospace, electronics/electrical, industrial and consumer markets.

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.
