Our products

Product category: Toolmaking, mold making

Micro Mold

Micro molding capabilities are the essence of what we do at Accumold. We started our company on this exacting manufacturing process and it remains at the heart of our operation today.

Parts made with our Micro Mold® process range in size from just microns to a half inch (13 mm). These components often have complex geometry and very tight tolerances—with no margin for error.

Small Part Molding

Small parts are slightly larger than those within micro mold classifications: from a half inch to about 3 1/2 inches (9 cm) in diameter and made from a one-ounce shot of material. Even so, they require the same degree of precision and quality during production. Many have micron tolerances, and they can have micro-sized features measured in microns.

Lead Frame / Insert Molded Parts

Accumold can mold plastic on and around various types of metals, plastics, fabrics, foils and complex components without damaging or warping the structure in any way. Some of these processes produce complete parts, while others are ready for further processing by our customers or their contract manufacturers. In many cases, high-speed handling can be added to these processes to save resources.

2-Shot Micro Molding

In micro molding, two different plastic materials are shot in sync during a single operation. Our customers use this type of micro molding process to lessen the amount of labor required, create a more robust part configuration, or increase cost savings. This process also is capable of handling other applications, such as cosmetics or touch-and-feel applications.

Insert Specialty Micro Molding

Insert micro molding encapsulates a wide variety of materials such as metal, glass, fabrics, flex-circuits and other delicate media. These parts, similar to those created with 2-shot molding, not only reduce handling and assembly they can solve critical issues in manufacturing.

Laser Direct Structuring (LDS) / 3D-MID

A complementary process to specialty micro molding is Laser Direct Structuring or often referred to as 3D-MID. This selective plating process is a perfect fit for Accumold’s Micro Mold® technology. Inquire about partnering with Accumold for your micro molding part of this process.

Micro Structure Enhancements

Accumold combines small and micro-sized parts with the ability to mold micro structures on the surface of the part. These features can measure under one micro in size and are used in a wide variety of applications like diffractive optics, micro-fluidics or micro lenses.

About us

Company details

The Accumold Story

Dedicated to micro since 1985
Like many great start-ups, Accumold began operations in a rented garage. Our founders discovered there was a growing need to manufacture small and micro injection molded components that went well-beyond the available molding systems of the day. This discovery led to the invention of our first Micro-Mold® platform in 1985.

Since those early days, our focus has remained steadfast to the art and science of micro injection molding. In fact, Accumold is the only company that has been continuously dedicated to micro molding for over 30 years. We remain committed to serving high-tech industries that require high-volume, small, complex micro injection molded parts with high quality and fast turn-around.

Expertise to produce your most exacting parts
Some large-injection molding companies purchase smaller molding machinery and then claim to offer micro molding processing. But a machine alone won’t deliver the precision your parts require.

An understanding of the physics, material science, and manufacturability in micro molding is every bit as important as the machines and instrumentation.

Accumold has been an expert in micro molding for more than three decades—and many of our professionals are with us their entire careers. We continue to add to our knowledge base with the brightest, most skilled technicians in the business. We have a long-standing relationship with Des Moines Area Community College (DMACC), which offers one of the finest educational and apprenticeship programs for toolmakers in the United States. Countless DMACC graduates bring their talents directly to Accumold.
