Incorporated in 1989, Microplastics operates within a 50,000 square foot facility in St. Charles, IL. State-of-the-art injection molding machines produce thousands of insert molded components three shifts a day. The facility houses a full-service Tool room with advanced CNC, EDM and SLS (Selective Laser Sintering) capabilities. Our engineering group provides design assistance and develops products using the latest solid modeling tools in the industry.

We control the entire process in-house, from engineering and tooling through molding and assembly. Our program management team guides each project from design and development through part approval and production. Bringing a project in on time, within budget, is a strength we possess.

Insert molding can be a highly efficient alternative to the assembly of discrete parts using soldering, connectors, fasteners, or adhesives. Its benefits over such methods include:

• Reduced assembly and labor costs
  Because insert molding joins numerous components with thermoplastic, assembly and labor costs are greatly minimized. For example, a single stamping can be overmolded, then perforated to create multiple circuit paths.
  
• Reduced size and weight
  By eliminating fasteners and connectors, and by combining the physical strength of resin and metal inserts, insert molding yields smaller and lighter components.
  
• Increased reliability
  With every part tightly secured in thermoplastic, an insert molded component prevents part loosening, misalignment, improper terminations, and other problems. The thermoplastic resin also provides improved resistance to shock and vibration.
  
• Increased design flexibility
  Designers appreciate the virtually unlimited configurations that insert molding allows. For example, in creating a 3D circuit board, overmolding permits circuitry to move freely through the part, from inside to outside, up walls, down in holes-and the plastic ties it all together.
