What Is Sajar Plastics Inc.?
Sajar Plastics Inc. is an American company that makes custom plastic parts. It works with other businesses that need special parts for their products. These parts can be large or small and may have different shapes and uses.
Unlike stores that sell plastic items to shoppers, Sajar makes parts for other companies. For example a medical equipment maker may need a strong plastic cover. Sajar can help make that cover based on the customer’s design and needs.
The company is best known for making large plastic parts with a smooth finish. It uses special machines and molding methods to do this work. Its long history has helped it gain experience in making parts that fit well and look good.
The History of Sajar Plastics Inc.
The story of Sajar Plastics began in 1949. The company started its work in Middlefield, Ohio. At that time plastic manufacturing was growing in the United States. Many businesses were looking for new ways to make useful products.
As the years passed Sajar Plastics learned new ways to make plastic parts. It became known for making large and detailed products. Its workers also gained experience with special molding methods that were not common in every factory.
During the 1980s the company became involved in the early growth of gas-assist molding. This method helped make large plastic parts with less material. That work became an important part of Sajar’s history and helped shape its future business.
Who Owns Sajar Plastics Inc. Today?
Sajar Plastics Inc. became part of Universal Plastics in 2017. The new owner wanted to add more plastic molding services to its business. Sajar already had years of experience making large and complex plastic parts for customers.
Universal Plastics was known for another method called thermoforming. This method uses heat to shape plastic sheets. By joining with Sajar the group could offer customers more ways to make plastic products based on their needs.
In 2026 Sajar continues as part of Universal Plastics Group. The Middlefield operation is also known as Sajar Molding Services in public records. Although the ownership changed, the Sajar name is still used for its special molding work.
What Products Does Sajar Plastics Inc. Make?
Sajar Plastics Inc. makes many types of plastic parts for other companies. These include machine covers, handles, doors, panels, cabinets, and equipment housings. Each part is made to match the design and needs of the customer.
Think about a large medical machine in a hospital. It may have a plastic cover that protects its inner parts. That cover must fit the machine and look clean. This is the kind of custom work Sajar can help produce.
The company also makes parts used in business machines and factory equipment. Some parts need to be strong while others need a smooth surface. Sajar uses different molding methods to meet these needs and make useful finished products.
Sajar Plastics Inc. Manufacturing Services
Sajar Plastics Inc. offers several ways to make plastic parts. Its main services include gas-assist molding, structural foam molding, and standard injection molding. Each method works in a different way and helps make different types of products.
Gas-assist molding uses gas during the molding process. This can help make large plastic parts lighter and reduce unwanted marks. Structural foam molding makes parts with a lighter inside and a firm outer layer. Both methods can help with larger products.
Standard injection molding is another important service. It uses melted plastic that is pushed into a mold. Sajar also offers painting, printing, assembly, and other finishing work. These services help customers receive parts that are closer to being ready for use.
Why Is Sajar Plastics Inc. Known for Gas-Assist Molding?
One special thing about Sajar Plastics Inc. is its long history with gas-assist molding. The company took part in the early development of this method during the 1980s. This helped it build knowledge that became useful for many customers.
Gas-assist molding works by using gas inside the mold while the plastic is being shaped. The gas can create hollow areas in thicker parts. This may reduce weight and plastic use. It can also help stop unwanted marks on the surface.
Imagine a large plastic handle used on a machine. Making it fully solid could use more plastic than needed. Gas-assist molding may help create a lighter handle while keeping useful strength. This is one reason Sajar became known for this special process.
What Industries Does Sajar Plastics Inc. Serve?
Sajar Plastics Inc. works with many types of businesses. Its plastic parts are used in medical equipment, factory machines, and office systems. These businesses need parts that are strong and fit their products. Sajar helps meet these needs.
The medical field is one important market. Large medical machines often need plastic covers and panels. These parts must look clean and fit well. Sajar also makes parts for laboratory equipment and machines used for testing different things.
