Our History

In the first half of 2008, five long-term service providers in the plastic injection molding industry came together as one integrated company to form Spectrum Plastics Group. Each company provided an area of expertise that would enhance the service offerings of the total group. Today, the newly formed Spectrum Plastics Group is your One-Stop Injection Molding Partner.

Minnesota Facility

Since 1958, this facility has been involved in injection molding, assembly, and supply base management as a contract manufacturer to produce a wide variety of components, sub-assemblies, and finished products. Emerging as a leader in processing highly engineered plastics, the Minnesota facility was an industry leader in providing plastic contract manufacturing to customers in highly regulated industries. Focusing on customer's needs for a full service contract manufatcurer, Midwest Plastic Components became a leading supplier to the Medical, Aerospace, Defense, and Precision Industrial markets.

As part of their strategic business plan, Midwest Plastic Components purchased two injection molding facilities and two prototyping companies to enhance the service offerings and provide more manufacturing location options to its customer base. To encompass the philosophy and articulate the expanded services offered to the customers, the name was changed to Spectrum Plastics Group, as of June 1, 2008.

California Facility

The original company was started in 1977 as a supplier to the Toro company providing components manufactured from engineered resins. In 1995 the company was purchased by a young engineer who built a thriving injection molding business focused on providing customers quality engineered products. In December, 2007 the business was purchased by Midwest Plastic Components.

The current manufacturing facility houses state-of-the-art equipment allowing it to efficiently run both long and short production runs. All machines are equipped with robots to allow more consistent cycles and minimize part handling and hence reduce potential marking or damage. The production philosophy hinges on its commitment to Statistical Process Control. Operators perform process and dimensional audits to ensure the dimensional accuracy, physical properties, and consistency of parts.

Connecticut Facility

Spectrum Plastics Connecticut facility was started in 1967 and is located in Ansonia, Connecticut. The company was founded as a highly engineered processor of injection molded plastics. The company was a pioneer in developing highly engineered and automated reel-to reel molding and continues today as one of the few companies capable of providing this service.

In 1999, a new 66,000 square foot state-of-the-art molding facility was built. The bright work environment with controlled environments was built and conceived with efficiency and safety in mind.

In February, 2008 Midwest Plastics Components purchased the Connecticut facility to enhance the services available and offer manufacturing in the Northeast market.

New York Facility

Dynacept Company, Inc. was founded in 1973 and located in Bedford Hills, New York. The company began as a quick-turn conventional Model Maker. Exclusive focus was placed on striving to satisfy the needs of the customer. This was successfully done by investing in the best technologies and focusing on outstanding customer service.

In September of 2000, Dynacept relocated to a 30,000 square foot facility in Brewster, New York. This facility houses the largest SLA service bureau on the east coast, a very substantial rubber molding and urethane casting department, and an unsurpassed rapid tooling and molding department.

Recognizing the need to expand current operations and to offer complete production capabilities, Dynacept was purchased by Midwest Plastic Components in December, 2007. Dynacept now operates as a division of Spectrum Plastics Group.

Colorado Facility

In January of 1990, two gentlemen with strong plastics molding, tooling and prototyping backgrounds, joined forces and founded Protogenic, Inc.

Protogenic’s philosophy is to utilize rapid prototyping technologies to reduce their clients' time to market and product development expenses. Located in Westminster, Colorado, Protogenic has approximately 22,000 square feet of manufacturing space. As the company grew its stereolithography and urethane cast parts services, the quality standards set by the founders established Protogenic's reputation as a high quality leader in the industry.

Protogenic is a professional service bureau that manufactures prototypes and conceptual models using stereolithography (SLA) and Laser Sintering (LS) rapid prototyping technology. Protogenic also offers silicone rubber (RTV) molds and cast polyurethane parts for limited 'pre-production' quantities.

Under strong leadership, Protogenic continues to explore and apply leading edge technologies to produce the finest prototype parts and ensure the highest levels of customer satisfaction.

New Name, Same Great Service

Operating as one company, Spectrum Plastics Group's philosophy is based on a customer-focused strategy to provide expanded capabilities and conduct business as an integrated One-Stop injection molding partner focused on the unique needs of each and every customer.
