With compression molding it is possible to produce simple flat panels or highly complex 3-dimensional (3D) parts quickly and accurately using inexpensive tooling at lower pressures.
Furthermore, these parts have less molded-in stress (which can otherwise lead to post-mold warpage) and do not have knitline issues associated with other processes.
Long-Fiber Reinforced Thermoplastic (LFT or LFRT)
CTC has developed its own patented long-fiber reinforced thermoplastic process. LFT (or LRFT) is a molding process where glass and resin are combined in a plasticator, and then shaping it in a compression molding machine. This process has several benefits:
• Allows for greater stiffness of parts without causing increased brittleness
• Produces reinforced thermoplastic composites that can be customized on-the-fly
• Customers can obtain non-standard glass/resin ratios without paying a cost penalty
• Customers don’t have to purchase large lots of custom compounded material.
Extruder and Screw Technology
With our patented extruder and screw technology, we are able to maintain greater glass length than can be realized in injection molding or other typical LFT processes. Consequently parts maintain higher mechanical properties, even in:
• Deep ribs
• Bosses
• Standoffs
• Deep draws
