Large Package Die-Cast Dies and Plastic Injection Molds Capability

General Die & Engineering builds middle-to-large die-cast dies and plastic injection molds. Most shops handle tooling up to the 20,000-pound range. General Die & Engineering can handle tools up to 160,000 lbs. We can also work with large multi-tool packages.

Our niche is plastic injection molds, die-cast dies, coining/straightening dies. We work with demanding specifications, such as those required in the lighting industry. We are experts in decorative and high-finish parts.

1979 - Impact Industries Purchased General Die & Engineering

In 1979 Impact Industries, a die-cast company located in Sandwich, Illinois, purchased General Die & Engineering. The business soon moved to a new 15,000-square-foot facility in the Grand Rapids suburb of  Wyoming, Michigan, where it continued operations for almost 20 years.

1996 - Purchased Arbor Mold & Engineering

In 1996, General Die & Engineering purchased Arbor Mold & Engineering, Inc., which owned a 25,000-square-foot facility in Grand Rapids. The acquisition of this second facility significantly expanded General Die & Engineering's capabilities, allowing us to manufacture molds and dies up to 80,000 lbs.

2000 - Merging Two Operations into One

By the year 2000, with both facilities nearing capacity, plans were made to expand and merge the two operations into one. Ultimately, the consolidation would streamline operations and allow us to be more competitive. When the expansion was completed in 2001, General Die & Engineering had a 68,000-square-foot manufacturing space.

Our success in an industry that demands excellence is no small achievement. Due to global competition, manufacturers have been forced to raise the quality of their goods while simultaneously lowering costs. Along every step of the way, General Die & Engineering has met that challenge.

Today - Giga Press Tooling

Always looking toward the future, General Die & Engineering is investing resources in tooling for the Giga Press. Giga Press die casting is the most recent advance in aluminum die casting. Currently, Tesla has invested in four Giga Press machines manufactured by IDRA Group for their Model Y automobile.

These massive die-casting machines range in size from 5,600 tons to 8,000 tons. They are the largest high-pressure die-casting machines in the world. A single machine weighs almost one million pounds. These machines take a 180-pound shot of molten aluminum and cycle into a complete part in 90 seconds. A single machine can produce up to 1,000 aluminum castings per day. (Source: Wikipedia)
