Trelleborg Calls it 2C LSR Technology - The Ultimate LSR Process

LSR membrane

One of Trelleborg's most outstanding capabilities is the simultaneous injection of LSR in combination with technical plastics, 2C LSR technology. In what is commonly also referred to as 2K, 2-shot, multi-component injection molding, or co-injection, Trelleborg employs highly advanced and sophisticated tool and process engineering to develop the most innovative solutions, combining two, three or more individual materials into one fully bonded, robust component.

General advantages of LSR

  • Enables production of part geometries and technical solutions not possible otherwise
  • Flashless, wasteless product quality
  • Provides the highest consistency in product dimensions, precision, and overall quality due to lean manufacturing processes
  • Enables highest volume production as a result of short cycle times
  • Offers the lowest TCQ (Total Cost of Quality)
     
Advantages of 2C LSR technology
  • Offers designers much more latitude in design solutions
  • Can integrate multiple components into one fully-bonded solution
  • Single component is more robust than an assembly of individual parts
  • Provides lighter weight components
  • Risks and costs associated with secondary assembly can be avoided
  • Enables more hygienic design solutions
  • Lowers cost by reducing the number of components in the customer’s supply chain
