    Feedscrews
    Our coatings are perfect for injection molders and extruders when processing fiberglass, calcium carbonate, titanium dioxide and metals, ceramic or other highly abrasive fillers.
  • Mixer-Extruders
    Continuous Mixing Rotors
    Our C1000 tungsten carbide has been used as chrome replacement in aggressive applications. C1000 doubles the working life of rotors compared to hard chrome plating.

ROI

The plasticizing feedscrew is the heart of any injection molding or extrusion machine. These machines are designed to convert plastic pellets or powders into sellable products. As feedscrews begin to wear, this conversion process is negatively affected. Maintaining the feedscrew in a like-new condition assures process consistency, lowest conversion cost and the highest level of good (sellable) production.

Process effects of wear

Injection Molding Extrusion
Increase in plasticizing time Drop in output rate
Increase melt temperature Increased melt temperature
Degradation products Gel formation
Shot inconsistency Extruder surging

Examples

LCP injection moldingHDPE pipe extrusion
Maximum wear allowable .018” (.45 mm) 120 days operation
Nitrided steel life: 300,000 shots C83 hard facing, .090” (2.2 mm) wear
Tool steel life: 1,500,000 shots 1,250,000 lbs
XC1000 life: 4,000,000 shots XC1000 coating, .010” (.125 mm) wear 1.550,000 lbs

Intangible costs are difficult to calculate but often represent a multiple many times the cost of coating a feedscrew in terms of lost productivity and profit. Overall production consistency and repeatability are the benefits from a feedscrew in like-new condition over a longer service life.
