Our Enduring Values

Earle Segrest GreenLeaf Industries | Plastic Injection Molded Design in Custom Plastic Parts
Earle Segrest, President GreenLeaf Industries

GreenLeaf Industries was founded in 1999 By Earle Segrest and his son Lawrence. Earle understood that two essential keys for success were excellent products coupled with unmatched customer service. These “north star principles” were present at our founding, and they still endure today. These principles are in our corporate DNA, enshrined in our Core Values, and infused throughout our systems. This allows GreenLeaf to confidently make four customer promises that are concrete, meaningful, and backed up 100%.

From the very beginning GreenLeaf focused on using technology to increase quality and reduce costs. Back in 1999 all-electric molding machines were a very small part of the molding machine market. Having received some bad press in the early 1990’s, many molding shops and equipment manufacturers had written off the all-electric molding technology as a passing fad. GreenLeaf, on the other hand, recognized that all-electric machines produce superior, consistent parts, and they are cheaper to operate. Starting with our first three machines, we were and we remain a 100% all-electric molding machine company.

While the all-electric machines were a cornerstone for molding excellent products, it was our heart and attitude that created our reputation for unmatched customer service. In the early years, Earle and Lawrence wore many hats—including customer service. When emergency orders would come in, it was Earle and Lawrence who would work through the night to fulfill the emergency orders, and personally deliver them to save shipping time. They did whatever it took to keep our customers production line going. Today, two of GreenLeaf’s Core Values reflect our founders’ belief in uncompromising service: “Grit… getting it done when it’s hard,” and “Service, especially when it hurts.”

Says Earle Segrest: “It is gratifying to see the values that GreenLeaf was founded upon being lived out every day through our dedicated employees.”

All-Electric Injection Molding Machines

All-ElectricAround the world, very few plastic injection molding companies exclusively utilize all-electric equipment. Most molding facilities continue to use conventional hydraulic equipment due to the higher initial cost of these state-of-the-art all-electric machines. In comparison, GreenLeaf Industries is one of the only all-electric plastic injection molding companies in the world!

Although electric plastic injection molding machines are initially more expensive than their hydraulic counterparts, they are more cost-effective to operate, resulting in piece prices that are lower than those made on hydraulic equipment. In addition, these machines produce a superior quality product. At GreenLeaf Industries we use our expertise in problem-solving to take what seems to be “impossible” and helps make it possible for our customers.
