The company uses large machines to make these parts. It has different ways to shape plastic. These include gas-assisted molding and foam molding and standard injection molding. Each method helps the company make parts for different needs.

The Early History of Sajar Plastics

The story of Sajar Plastics began in 1949. The company opened in Middlefield, Ohio. It started with just three plastic-making machines. It was a small start. But the company wanted to make useful parts for other businesses.

At that time more businesses were starting to use plastic. Plastic was useful because it could be shaped in many ways. It could also be lighter than metal. This made it a good choice for many machines and tools.

As more customers came to Sajar it got more work. Its workers learned how to make better parts. They also learned new ways to shape plastic. Little by little the company became known in the plastic-making business.

How Sajar Plastics Got Its Name

The name Sajar has an interesting story. An old company booklet says the name came from the last names of its three founders. They used parts of their names to create the business name.

As time passed more people learned about Sajar. The name became linked with large plastic parts. The company also became known for making parts with special shapes.

A name can help people know a business. But good work is what helps a business grow. Sajar kept learning new ways to make plastic parts. This helped the company build a strong name over many years.

How Sajar Plastics Grew Over Time

Sajar Plastics did not become a big company in one day. It took many years to grow. The company started with only three machines in 1949. As it got more work it needed more space and better machines.

Today Universal Plastics Group says the Sajar factory has about 150,000 square feet of space. That is a large area for making plastic parts. The factory has machines that can make both small and large parts.

Better machines helped Sajar take on bigger jobs. The company could make parts with more shapes and sizes. It also added more ways to paint and finish its parts.

The company grew by learning new things and improving its work. It did not only focus on making more parts. It also worked to make better parts for its customers.

What Products Does Sajar Plastics Make?

Sajar Plastics makes plastic parts for other companies. Many of these parts are large. They can include covers and doors and handles and frames. The company also makes panels and boxes for machines.

For example a medical machine may need a large plastic cover. This cover helps protect the parts inside. A store may need a plastic panel for a machine that customers use by themselves.

Sajar does not make every kind of plastic item. Its main work is making parts with special shapes and sizes. These parts must fit well with other pieces. They also need to look neat and work well.

Every customer may need something different. One may need a large cover. Another may need a strong handle. Sajar works on these needs and makes parts that fit each job.

How Sajar Plastics Makes Plastic Parts

One of the main ways Sajar makes plastic parts is called injection molding. The name may sound hard. But the process is quite simple.

First small pieces of plastic are put into a machine. These pieces are called pellets. The machine heats them until they melt. Then it pushes the hot plastic into a metal mold.

A mold is a strong metal tool with a shape inside it. The hot plastic fills this shape. It then cools and becomes hard. After that the mold opens and the new plastic part comes out.

The same mold can be used again to make more parts. This helps the company make many parts that look alike. But workers must check each step. The right heat and pressure help make good parts.

Sajar Plastics and Gas-Assisted Molding

One big part of Sajar’s story is its work with gas-assisted molding. This method became important in the early 1980s. Universal Plastics Group says Sajar was one of three early companies that helped develop this method.

So what is gas-assisted molding? It is a way to make plastic parts with the help of gas. First hot plastic goes into a metal mold. Then gas is pushed into some parts of the mold. This gas helps shape the plastic.

The gas can also make empty spaces inside thick plastic parts. This can help save plastic and make some parts lighter. It can also help stop small dents from showing on the outside.

For example a large plastic handle may look solid from the outside. But it can have an empty space inside. It can still be strong enough for its job. This method is useful when a part needs to be big but not too heavy.

Sajar has used this method for many years. Universal Plastics says the company has helped make more than 500 gas-assisted part designs for customers. This work helped Sajar become known for its special way of making large plastic parts.

Other Molding Methods Used by Sajar Plastics

Sajar Plastics uses more than one way to make plastic parts. One of these ways is called foam molding. It helps make large plastic parts that are strong but not too heavy.

In this method small air bubbles form inside the plastic. This makes the inside lighter. The outside stays firm. This way is useful for large covers and machine parts. Some parts may also need paint to look nice.

Sajar also uses a simple way called standard injection molding. It helps make many plastic parts with the same shape. These three ways give the company more choices when making parts for its customers.

Industries Served by Sajar Plastics

Sajar Plastics makes parts for many types of businesses. One main field is medical machines. These machines need large plastic covers to keep their inside parts safe. The covers must have the right size and shape.

The company also makes parts for lab machines. These machines are used to test and study many things. Sajar also makes parts for store machines and office tools. For example a store may need a plastic part for a payment machine.

Every business has its own needs. Some need light plastic parts. Others need large and strong covers. Sajar makes different parts to help these businesses build their own products.

Sajar Plastics Ownership and the 2017 Sale

Sajar Plastics has had more than one owner over the years. In 2008 it became part of Main Street Capital Holdings. This was a business group based in Pittsburgh. The factory kept making plastic parts during this time.

In 2017 another big change took place. Universal Plastics bought Sajar Plastics. The sale was announced in July 2017. The price of the sale was not shared with the public.
