Materials

Thermoplastic Materials:

Rakar has the knowledge & capability to mold many types of thermoplastic materials. We typically use engineering grade resins ranging from Nylon & Polyester to high performance resins such as PEEK & LCP. Having produced small, medium & large production runs of thousands of different products, Rakar can meet your specific injection molding requirements from simple to complex sizes, shapes & tolerance. Thermoplastic Resins having specific properties are compounded with additives such as reinforcements (glass or carbon), U.V. inhibitors, flame retardants, conductive elements, lubricants or toughness agents, to attain desired properties. Some thermoplastic property benefits include:

 

  • Resins are available in a wide variety of material & color options.
  • Low Cost alternative to molding large quantities of steel & stainless steel.
  • Proven Durability
  • Hi Corrosion & Chemical Resistance
  • Hi-Temperature Tolerance
  • Excellent workability, thermoforming & molding characteristics
