We are a team of problem solvers that strive to find optimal design features and part performance. 


  • Concept Feasibility: How your design can be produced and how it functions as a consumer product.
  • Alpha Research: Design Improvement with prototypes, design iterations and product feature changes.
  • Beta Development: Completion of single cavity tooling production parts for testing & validation.
  • Qualifications: Production Tooling and First Article completion.
  • Product Launch: Stock level builds and Introduction to the market.
  • Review of your part file.
  • Implementing changes for moldability.
  • Redlining documenting how changes can help the part
  • Review, repeat, and recycle.
  • Finalize file with Print and part number.

SPEED TO MARKET in mind!  Success is achieved through cross-functional team efforts with a “continuous improvement” mindset. Products are developed with a specific “Value to the Customer” goal in mind.   When we get to know your goals, we can help you steer the development to meet those goals.  Listening to your market hot buttons is key to both party’s success.  All components and assemblies are intimately examined and developed for ergonomics, fit and function, tolerance stacking, lifecycle performance.


Hinj is organized around the idea of dematerialization and performance optimization through the research and development of compliant mechanisms.  A compliant mechanism is a mechanical structure or device that achieves motion or force transmission through the deformation of its flexible components, rather than traditional rigid joints and connections. Compliant mechanisms are designed to bend, twist, or flex to perform a specific task or function, without the need for traditional hinges, screws, or bearings.


Our Team sees things differently than most injection mold houses and that is why we are different. We passionately look at itemizing and prioritizing cost structure related to your manufactured part knowing all the tradeoffs during the critical decision points of the process. This is our wheelhouse and we love helping OEM’s like you in this areana!

Our business strives on getting you into a low-cost production tool while minimizing cycle time with consideration of performance and cosmetics. We are very upfront with our costs so you can contribute to the optimized design. We are very forward to how your part will be priced based on a few simple parameters.


Molding Trial report is one of the most important steps in the qualification of your part. Keep in mind all these factors play into getting you to the perfect part for your application. T1 Samples will be evaluated prior to Texturing and will show 90% of how the part will mold. At this time adjustments are commonly made to the mold and process including but not limited to Gate sizing, Vent sizing, and location, wall thickness modification to minimize sink and match plating to minimize any flash.

At this time Process parameters are also monitored very closely to understand how fast the mold fills, where any knit lines end up with respect to the original mold flow analysis. Zone temperatures, and of course cycle time are needed to complete the process for an acceptable part and its impact on the financial metrics.

Rely on us to find the right tool to solve your analytical problem. Those motivated and Skilled in the art of problem solving will give you confidence.
