Guill extrusion heads: crossheads, in-line and rotary heads, tips and dies

Guill 700, 800, 600 and 500 Series crossheads, 900 and 2000 Series in-line heads, 300 Series rotary heads, corrugated and blow molding heads, tips, dies, heaters and deflectors. Selection per line, quotation per project.

700, 800 and 600 Series crossheads

The 700 Series crosshead is fully adjustable and accepts existing tips and dies. The 800 and 600 Series run fixed center or adjustable with split balanced flow, heated by built-in cartridge heaters.

800 Series: two to six layers
Model 832: max die 152.4 mm
700 Series: models 712 to 725
Fixed to adjustable in two minutes

500 Series rubber and silicone crossheads

The 500 Series is built for elastomers: the MAGS gum space is set from a single point with a common socket wrench. A cam lock extracts the deflector with half a turn of the cam nut, and Easy-Out inserts let you replace a locked adjusting bolt.

Models 520, 523, 525 and 527
Model 527: max die 76.2 mm
Integrated cooling jackets
Drop-in on most NRM lines

900 and 2000 Series in-line heads

The 900 Series spiderless in-line heads for pipe and tubing have fewer parts, split balanced flow and built-in cartridge heaters. The 2000 Series covers large diameters with a heated core pin and a low volume flow path.

900 Series: models 919 to 934
Models 934 and 2034: 228.6 mm die
Core diameter up to 215.9 mm
2000 Series heated core pin

300 Series rotary heads

In the patented 300 Series heads the tip and die rotate in opposite directions, so the polymer chains cross at an angle. The tube wall gets stronger, and the tube can be made thinner with less polymer.

Speeds up to 1,000 rpm
Models 323, 325, 332 and 334
Model 334: max die 228.6 mm
Counter-rotating tip and die

Heads for corrugated pipe, blow molding, profile and pellets

The 400 Series feeds the corrugator through a multi-port spiral with no weld lines. The 1000 Series covers blow molding dies. The 200 Series balances flow for profiles and seals, and the 100 Series are strand pelletizing heads.

1000 Series core up to 254.0 mm
400 Series: models 420 to 434
1000 Series: one to three layers
100 Series: single or multi-strand

Tips and dies

Guill tips come as fixed center shoulder, tapered, threaded, snap-together, profile and multi-lumen styles. Dies come as face seal, floating adjustable and shouldered styles. The steel is qualified for the polymer to be extruded.

Tip part number: XXX14XXX
Die part number: XXX15XXX
Tool steel or stainless steel
Monel, Inconel, Hastelloy

Heaters, breaker plates and flanges

Guill heads use cartridge, bronze, ceramic, band and mica heaters, heated core pins, and removable or integrated heating and cooling jackets. Breaker plates are designed for the polymer and the screen pack, and flanges come in clamp style and bolt-on style.

Breaker plate number starts 24-
Cartridge and band heaters
Removable or integrated jackets
Twin screw flanges

Deflectors and concentricity adjustment

The FlexiSpiral deflector eliminates weld lines and allows lower die pressure, and QuadraFlow for rubber splits the melt into four flows. Tip and die concentricity is set with the FeatherTouch die holder or with Single Point Adjust using one bolt.

Single Point: 0.008 in per turn
One bolt for 360° adjustment
FeatherTouch: 6-inch wrench
QuadraFlow: four-way flow

How to choose a Guill extrusion head

Selection starts with the product and the material. For jacketing and multi-layer tubing, crossheads fit: the 700 Series is fully adjustable and accepts existing tips and dies, the 800 Series runs two to six layers, and the 600 Series allows flexible extruder orientation.

The 500 Series is built for rubber and silicone.

For pipe and tubing without a spider, the 900 Series spiderless in-line head fits, and the 2000 Series covers large diameters with a max die of 228.6 mm. The 300 Series rotary head strengthens tube walls, the 400 Series works with corrugators, and the 1000 Series serves blow molding.

Concentricity and adjustments

Guill heads run fixed center or adjustable: on the 800 and 900 Series, changing one component makes the head fully adjustable in two minutes. Adjustment is made to the gum space, the tip or the die.

Single Point Adjust controls 360° of concentricity with one bolt and is available on new crossheads up to 1.250 in die ID. The FeatherTouch die holder is adjusted with a small wrench. A properly aligned head needs little or no adjustment.

Tips, dies and materials

Tips come as fixed center shoulder, tapered, threaded, snap-together, profile and multi-lumen styles; dies come as face seal, floating adjustable and shouldered styles. Tip part numbers follow XXX14XXX, die part numbers follow XXX15XXX.

Tool steel and stainless steel serve plastics, while Monel, Inconel and Hastelloy serve fluoropolymers. Breaker plates are designed for the polymer and the screen pack, and heaters come as cartridge, band, ceramic and mica types.

Cleaning and maintenance

The head is cleaned while hot, one component at a time, with brass and copper tools. Open flames and steel scrapers are not used, and a cleaning oven suits plastics only and must not exceed 454 °C.

Fasteners are tightened gradually in a star pattern to the torque in the manual. Each crosshead ships with an assembly and disassembly tool kit and an operator manual, and alignment pins center the tip and die during assembly.
