Plastic Product Design - Product Development Prototypes

Designing a plastic part is a complex task involving many factors that address a requirements list of the application. At BMI Injection Molding & Assembly, we know all of the questions to be asked. With that information, we have the cost-effective solutions to create the product that you have envisioned - turnkey.

“How is the plastic part to be used?”
“How does it fit to other parts in the assembly?”
"What is the right thermoplastic material to use?"
"What mold tooling should be used?"
“What loads will the part experience in use?”

Design Considerations

In addition to functional and structural issues, processing issues play a large role in the design of a plastic injection molded part.

How the molten plastic enters, fills, and cools within the cavity to form the part largely drives what form the features in that part must take. Adhering to some basic rules of injection molded part design will result in a part that, in addition to being easier to manufacture and assemble, will typically be much stronger in service. Dividing a part into basic groups will help you to build your part in a logical manner while minimizing molding problems. As a plastic part is developed, we always keep in mind how the part is molded and what you can do to minimize stress.

Transforming Ideas Into New Plastic Products

  • Part or product creation through launch.
  • Intellectual property / patent search.
  • Product technical implementation.
  • Product concept rendering.
  • Rapid/functional plastic prototypes.
  • Product commercialization / launch.
  • Industrial product design / 3D data.
  • New product business analysis / product pricing.


From Product Concept Rendering, using virtual 3D models, to assistance with Intellectual Property & Patent Search.

Product Concept Rendering
If you have a idea and need to get it on paper we can help.

Industrial Design / 3D Data
Let’s us help your part idea become a reality, by creating virtual 3D models.

Intellectual Property
So you have a great idea. Should you protect it? We can help you with Intellectual Property decisions and guide you thru the Patent Search process carefully.


From Rapid & Functional Prototyping to in-depth Product Business Analysis including New Product Pricing.

Rapid / Functional Prototype
We’ll help you look good with form-factor prototypes you can use to demonstrate the product experience to key stakeholders.

Business Analysis / Pricing
Do you know your customer is? What does the customer buy? What does the customer consider value? We can help.


From detailed work on Product Technical Implementation to Product Commercialization & Product Launch.

Technical Implementation
Manufacturing readiness and producibility are essential to the success of a product, whether you’re making 100 or 1 Million units. Early involvement of our team ensures the integrity of the design will be maintained through manufacturing.

Commercialization / Launch
Taking a plastic injected molded product from concept to reality is challenging. The development plans we build provide the detail you need to achieve your next business or technical objective.
