What It Is

Exact Engineering Inc. (EEI) is a family-owned plastic injection molding and mold manufacturing company based in Holland, Michigan, USA. Public company information indicates that it has been producing production molds and rapid prototype molds since 1995, and has gradually expanded into in-house injection molding production. It is not an internet SaaS product or an online manufacturing platform, but a physical manufacturing service provider for industrial customers.

Core Capabilities

EEI’s capabilities cover product development, DFMA reviews, CAD design, reverse engineering, metal-to-plastic conversion, material selection, FEA/FMEA, MoldFlow analysis, mold design and manufacturing, mold transfer, mold maintenance, 5-axis CNC machining, and injection molding. On the molding side, it supports 45-310 ton presses, with materials including commodity resins, engineering resins, and specialty engineering resins. It also offers custom colors, insert overmolding, TPE/TPU two-shot overmolding, IMD/IML, and related processes. Its key selling point is the combination of an in-house toolroom and injection molding production lines, which can reduce the time lost when molds have to move back and forth between external suppliers.

Pricing

The official website does not publish pricing, minimum order quantities, or standard packages. This is a typical project-based quoting model. Actual costs will depend on the product structure, mold life class, number of cavities, materials, surface requirements, inspection requirements, production volume, and lead time. For complex industrial parts, customers will need to submit drawings, 3D models, or concept requirements for evaluation and discussion.

Pros and Cons

The advantages are that EEI offers a fairly complete service chain, making the transition from concept design to mass production relatively smooth. Its emphasis on DFMA, MoldFlow, and quality planning can help reduce development risks for injection-molded parts. Local mold maintenance capabilities can also help minimize downtime. The drawbacks are that the website feels somewhat old-school, with limited disclosure of case studies, certifications, quality systems, equipment counts, and customer industry references. It also lacks online quoting and self-service project management, so communication costs for overseas customers may be higher than with platform-based services such as Xometry or Protolabs.

Who It’s For

EEI is best suited for manufacturers in the US or North America, hardware brands, and parts teams in automotive, agriculture, home appliances, medical, and consumer products that need long-term mold maintenance, engineering collaboration, and stable injection molding capacity. If you only need low-cost prototyping or small-batch cross-border parts production, it may be worth comparing Chinese or global online manufacturing platforms.

Access from China

The website is a standard corporate site and is generally accessible directly from mainland China. However, its service delivery is primarily based on physical manufacturing in the US, so Chinese customers should carefully confirm time zone coordination, logistics, tariffs, payment methods, and intellectual property agreements.
