What is Plastic Injection Molding?

Plastic injection molding is a process for creating plastic products, using tool steel molds. To create your product, pre-colored plastic pellets are melted, injected into molds under high pressure (8,000 to 20,000 PSI), cooled, and ejected. This is an efficient, fast, and easily repeated process that can quickly and precisely produce numerous finished goods in a short time frame. The component parts can be manufactured for assembly via snap fits, fasteners, adhesive, and welding.

What is Thermoforming?

Thermoforming is a process that uses a sheet of plastic that is heated and softened to allow for molding. Then, using a vacuum, the sheet of softened plastic is formed around a mold. This process can be used to make everything from pudding cups to dog dishes, and it is often utilized to create aerospace components such as aircraft engine covers, flexible dust covers, and delicate instrument storage containers.

ISO 13485 Cleanroom Plastic Injection Molding

The International Standards Organization (ISO) sets regulations for many business processes, including ISO 13485, the standard on clean room plastic injection molding for medical devices. Cleanroom plastic injection molding is a manufacturing process that takes place in an enclosed, positive pressure room. A cleanroom is maintained by moving clean air through the room and preventing “dirty” air from returning. Our cleanroom is a Class 7. To ensure the room is clean, we use ultra-high particulate air filters, lint free suits, positive air pressure systems, and other preventive measures that meet or exceed ISO 13485 standards.

AS9100 Aerospace Plastic Injection Molding & Thermoforming

The International Aerospace Quality Group sets manufacturing standards for products that can be used in aircraft, including AS9100, the policy sets processes and restrictions on items produced through plastic injection molding and thermoforming. Meeting or exceeding this manufacturing standard is essential to ensure safety, and we follow the requirements of AS9100 to the letter, ensuring perfectly functioning, quality products.
