Accumold® is a global leader in the fabrication of precision micro, small and lead-frame injection-molded plastic components. We design for manufacturability, and provide tooling, mold building, automation, and packaging services. Using processes developed from our own technology, we design, build, and produce molds and parts for applications in the medical device markets and microelectronics markets. Micro over molding, 2-shot, and insert, are our core capabilities.

Our experience and capabilities in micro-molding and our commitment to innovation are what make us the global leaders in Micro-Mold® Manufacturing Solutions. Founded in 1985, our sole focus was and remains manufacturing what other companies could not; exceptionally small molded parts. The mission has not changed, but our capabilities have. Today the company focuses on industries that require fast turn around and complex parts for high tech markets such as Micro-Electronics, Medical, Micro-Optics, Automotive Electronics, and Military, as well as new emerging markets and technologies.

We are here to produce your critical components. We can create micro molded parts requiring micron tolerances, intricate geometries and extremely small features. Accumold is the only company that has been continuously dedicated to micro molding for over 30 years. Our service to high-tech industries that require high-volume, small, complex micro injection molded parts with high quality and fast turn-around is unparalleled.

Products & Services:

Micro-Mold® - parts from about 13mm (0.5") and smaller. Micro-sized parts are produced in our own micro-molding machines, utilizing proprietary processes that we started our business with over 20 years ago. Our micro-molded parts range from about 1/2 inch in size to parts with features measured in microns. These components often feature complex geometry with very tight tolerances.


Small Parts - parts up to about 90mm (3.5") in diameter or a 1 oz. shot weight. The largest part that we mold is approximately three inches in diameter, close to 1 ounce in part weight, using a 35 ton machine. Micro-sized features and ultra-precision tolerances are often requirements on these "larger" parts. Using Accumold's internal modifications, with standard presses ranging from 12 ton to 35 tons, parts are made with minimal waste and fast cycle times.


Lead Frame / Insert Molding - parts molded around other materials such as metal, plastic, film, fabric, glass, ceramic flex-circuits, other plastics.


Manufacturing lead frame molded parts requires fabrication of a system to feed the metal lead frame into the machine and to extract the complete component from the metal after the plastic has been molded to it. Our systems designers are experts in fabricating a trouble free and efficient system to mold the most sophisticated lead frame molded parts.


Insert micro-molding is where an existing or previously manufactured part is molded in and around a wide variety of materials from metals and glass to other plastics.

Unique Services

Design For Manufacturability: Using detailed design reviews, our engineering team works closely with your design engineers to ensure manufacturability and that expectations are met for the final part.

In House Tooling & Mold Building: We are vertically integrated. In-house tool design and fabrication ensures control of this delicate, complex process from start to finish. Cross-functional teams work together to build tools that are capable of molding production ready parts. Our dedicated maintenance team keeps our production on track.

Automation & Packaging: The care taken in designing and developing the first part extends to the last. We develop entire systems to protect and deliver quality parts to your specifications. Our automation team is devoted to designing and developing solutions just for you.

24/7 Production, Tooling and Quality Inspection: High-quality parts, quick turn-around and constant communication are requirements of our global customers. And our teams of experts work around the clock to meet the demands of production and tooling. 

Technical Highlights:

  • Accumold processes highly engineered resins including PEEK, Ultem® (PEI), and LCP.
  • Accumold can measure surface finish and surface profiles with our in-house white-light interferometer.
  • Our state-of-the-art Quality Department uses laser and optical metrology with sub-micron accuracy.
