RKT has specialized in multi-component injection molding for over 35 years, continuously refining our processes Our expertise in 2 and 3 component injection molding provides efficient and cost-effective manufacturing solutions for medical technology, diagnostics, and life sciences. This method consolidates production steps into a single process, minimizing the necessity for additional subsequent processes.
2- and 3-Component Injection Molding
3K Injection Molding for Insulin Pen Dosing Windows
An example of a 3K injection molding product in production is a dosing window for insulin pens made from three different plastics. The first is a transparent, slightly curved display providing a magnification function. A black frame used for demarcation and visual enhancement is molded onto the first, and finally, a white scale is applied for readability. Unlike printing, which could risk peeling over time, multi-component injection molding integrates these markings directly into the parts. This method ensures that dosage information remains clearly legible throughout the product’s lifespan. RKT’s precision tools for multi-component injection molding guarantee accuracy to tolerances of less than 10 micrometers, maintaining consistent high-quality plastic parts with stable processes.
