Sajar Plastics History and Description

Sajar Plastics Acquired by Universal Plastics

Heavy gauge thermoformer expands into gas assist injection molding

Universal Plastics, a heavy gauge thermoformer based in Massachusetts, has acquired Sajar Plastics, a gas assist injection molder based in Middlefield OH. Terms of the sale were not disclosed.

The strategic vision for the acquisition is that Universal Plastics currently services customers who start out with custom thermoforming and graduate to injection molding – Sajar’s low volume gas assist injection molding expertise provides Universal with the opportunity to support their customers further along the product life cycle. The expanded breadth of capabilities will allow a customer to stay with a Universal family company throughout the life of the product from lower volumes at inception to higher volumes as the product grows and matures. Further, the combined company can provide unbiased guidance on which process is better suited for a particular application. Sajar Plastics will continue to maintain their facilities, employees and procedures which have made them successful for many years. Universal’s commitment to customer-focused growth and investment for the future will enable Sajar and the entire family of companies to further expand the range of products offered to customers and service them better.

According to Jay Kumar, President of Universal Plastics, “Customer success is our top priority and guiding focus. Sajar’s synergies with our existing thermoforming businesses, Universal and Mayfield, are plenty – a strong management team, sound business processes and a commitment to top quality products are what we are going to build upon. Above all, we value our relationships with our customers and are committed to maintaining and growing the value that we provide to them.”

Said Larry Nowak, CEO of Sajar Plastics, “Sajar is delighted to be a part of the Universal Plastics family of companies.  We are excited by the prospect of bringing a unique combination of capabilities to both the customers of each company and to the broader market for large, complex and aesthetically demanding parts through the merging of Sajar’s deep knowledge and experience with gas assisted large part injection molding, and the large complex part thermoforming skills of Universal Plastics. “

Molding Business Services (www.moldingbusiness.com), based in Florence MA, served as the advisor to Sajar Plastics on the transaction.

Sajar History

Sajar Plastics was founded in Middlefield, Ohio in 1949 with three plastic injection molding machines producing straight injection molded parts. “Sajar” is an acronym reflecting the last names of the founding three owners of the company. Sajar grew steadily over the years expanding manufacturing capabilities and facility to over 150,000 sq. ft., a direct result of earning a reputation in the custom molding industry as an innovative molder supplying high quality large plastic parts with complex designs and high cosmetic requirements at competitive prices.

In the early 1980’s Sajar was one of the three original companies which developed gas assisted injection molding and continues to pioneer its use and application today. Since then Sajar has acquired the equipment and processing technology necessary for the production of large complexly designed parts and the quality culture required to produce consistent high quality cosmetics on customer facing components. To date Sajar has commercialized over 500 gas assisted parts for leading OEMs in a wide variety of industries including medical, laboratory and diagnostic, manufacturing, business, and retail registers/dispensing machines.

World Leader in Large, Highly Cosmetic Plastic Parts

Internal gas assist injection molding is a low pressure process requiring the introduction of a short shot of molten resin into the mold which is immediately followed by the injection of high pressure nitrogen gas. The gas flows through strategically located gas channels by displacing the molten resin in the channel interior, thereby forming hollow sections.

The pressurized gas pushes the molten resin tight against the cavity walls until the part solidifies, and the constant, evenly transmitted gas pressure keeps the part from shrinking and warping while also reducing surface blemishes, sink marks, and internal stresses. This process produces a large plastic part with superior surface aesthetics and tight dimensional control over large distances.

In external gas assist injection molding the molten resin is introduced into the mold but the gas is injected in a micro-thin layer between the back surface of the part and the mold core, thereby forcing the front surface of the part against the opposite side of the mold cavity. As the resin cools the pressurized gas guarantees the front side of the part precisely replicates the surface of the mold.

This process is best for high profile and large surface area plastic parts, especially those requiring detailed textures and superior surface aesthetics. Warp and sink marks are eliminated because the gas packs out the resin as it solidifies. As with internal gas assist, support ribs and bosses can be molded into the part yielding similar dimensional stability and tight tolerances. Molding pressures are also likewise reduced generating less residual stress on parts and wear on molds.
