Plastic Manufacturing Services

At Mina Product Development, we specialize in providing injection molding solutions that meet the needs of businesses, regardless of their size. Our focus is on providing a domestic injection molding solution in a timely and cost-effective manner. 


As a product development firm we work with our clients from concept to finished product through various stages such as: Design for Manufacturing (DFM), Proof of Concept, Validation / Testing, and Commercialization.

Our injection molds are quoted on in-house mold bases saving time and thousands in additional costs.

Injection Molding & Product Development

As a leading plastic parts manufacturer, we strive to provide a wide variety of services for our customers, from expert part engineering to high-quality final production. Wherever you find yourself in the production cycle we offer flexible solutions to help you streamline your supply chain and reduce costs.

Additional Molding Options


Multi-cavity injection molds increase production efficiency and reduce costs by fabricating more parts with each shot cycle. The more cavities your mold has the cheaper your individual part price. Multi-cavity molds are particularly useful for high-volume production runs, where time and cost savings are critical. 


Insert molding is a process to create complex parts with intricate shapes and features that would otherwise be impossible to manufacture. This molding process is ideal for the production of parts that require additional functionality, such as electrical or mechanical components, as these components can be integrated into the mold during the injection process.


Family molding is a molding process that is designed to produce multiple related parts in a single cycle. These parts may have different shapes or features. Family molds are an effective way to save money on tooling since you're producing all related parts in a single mold. Parts are recommended to be similar size, weight and material.

Medical Device Manufacturing


Expertise in Medical Device Components

We are ISO13485 certified, specializing in high-quality plastic parts for medical devices and prototypes. We create components via polyurethane/silicone casting and injection molding of thermoplastics like PC, PP, ABS, Acetal.



Our in-house screw machine fabricates large volumes of single-use parts and implantables cost-effectively. It handles parts up to Ø.750". Services include making titanium screws, plastic adaptors, and dental components.
