Custom Injection Molding

Whether it’s a simple product design or a complex assembly using our internal robotics and hand-assembly, we have custom plastic molding capabilities to fit your requirements and your supply chain expectations.

Scientific Injection Molding

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 custom plastic injection molding 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.

In each of these industries, we know quality and precision are key for each component. For that reason, we have on-site, dedicated personnel and equipment to perform part inspections for final product success, ensuring that our plastic injection molding processes meet all necessary requirements. At Crescent Industries, we draw on our deep expertise to take on your complex part design at any step of development — from concept to production — and are able to assist with design, engineering, manufacturability, secondary processes and more.

Our extensive experience in development and production of custom injection molded components has given us a deep understanding of what makes a successful process, and we apply the benefits of our CNC milling service to help you achieve that. Benefits include:

Engineering- and technology-focused personnel: Our engineers take a scientific approach to design and engineering, ensuring efficiency, quality, and results.

A versatile suite of capabilities: In addition to our CNC machining services, we offer a number of other services to assist you in every step of development — 3D printing for prototypes and testing, plastic injection molding for products requiring both plastic and metal components, kitting services to aid in finishing and fulfillment, and value-add services such as finishing, assembly and packaging.

Manufacturability expertise: In bridging the process from design to production, manufacturability is a key concern in ensuring quality and efficiency during production. Our engineers take design for manufacturability into account throughout the entire process and can work with you to apply these best practices to your product. Factors include mold design, material selection, production time, process choice, and more.

Process flexibility: Whether you are completing all production processes under our roof, or need components or products sent to another supplier, we are ready to assist you in any way we can. Whether for the full design and engineering cycle or just for a certain aspect of production, our expertise is available to make your product the best it can be.

Custom Injection Molded Part Design Guidelines

If you need custom plastic injection molded parts, chances are good we’ve got you covered. Every part design is unique, but not the elements that need to be considered for overall quality and manufacturing of your custom plastic component or device. 

Crescent Industries' engineers have 100+ years of combined experience in injection molding, with extensive knowledge of part designing, mold designing, part fill simulation and material expertise to help guide you during the design phase.

Engineering Expertise

With our continued investments into engineering resources, our team has the expertise and technical knowledge to assist with your products across various stages and complexity. We love to get involved in the earliest stages of product development to make sure that our customers have the plastic engineering expertise avoiding any costly hiccups in the development process.

We work directly with our customers’ engineering teams, providing guidance on the manufacturability of parts ready to be custom injection molded or to create a mold design with the proper actions, gate locations, temperature control and venting. Our expertise and experience with injection molding for pharmaceuticals and medical devices and components mean that we can provide knowledge and assistance that other providers cannot.

By utilizing Sigma Soft mold fill simulation software, we complete a 3D simulation of how the mold fills, packs and cools during the injection molding process as part of our DFM analysis process. Therefore, problems or concerns can be solved before the parts or mold are even produced.
