Plastic Injection Molding

CQM's modern 28- to 150-ton presses can mold parts from one to 11 ounces. These machines are equipped with microprocessor controls, hydraulic core pulls, and some have options for vertical clamp, part line injection and programmed intrusion.

CQM offers specialized services in insert molding, sonic welding and assembly methods. We perform over-molding onto plastic or metal sub-parts. Updating equipment and ongoing training keeps us current with advances in polymer technology and molding practices. A custom process control manual is developed for each product to ensure quality.

With thermoplastics, there are 26 families of plastics with 20,000 standard plastic formulations off the shelf. Common adaptations include color concentrate, fiberglass, lubricants, UV inhibitors, and flame-retardants. When custom or special plastics are specified, we procure custom-compounded materials from specialized suppliers. Color concentrate is available in standard colors, or custom colors where an exact match is needed. It is rare that we use recycled or wide-spec plastics in our products. Most of our products are made from high-quality virgin plastics that come with certification. Name-brand plastics are purchased from well-known suppliers such as DuPont and Dow.

CQM follows sound environmental practices. We recycle leftover or scrap plastics. We exceed the requirements of the local Clean Air Authority which adheres to DEQ guidelines.
