Here's a post that will appeal both to artists and engineers.
As the name implies, MTD specializes in micromolding. It's a niche in the plastics industry that few companies really tackle. According to MTD's definition, micromolded parts so small you need a microscope to see them, or parts as large as 1-inch-by-1-inch that have micro features.
The vast majority of products MTD makes would fit into a space of three square millimeters. That point really hit home on my company visit, when you realize the company's warehouse of finished parts is basically the size of a filing cabinet.
Another cool thing about MTD was the interesting photographs that the company uses to illustrate the micro features of its parts. Director of Marketing Lindsay Mann explained that the company uses a local photographer in nearby Sturbridge, Mass., to take the photos.
