Engineered for Output Quality and Machine Longevity

1. Precision Screw & Barrel Metallurgy

The heart of our extruder is built to withstand high torque, abrasive wear, and thermal stress.

• Material: 38CrMoAlA high-grade alloy steel with nitriding treatment (Depth: 0.5–0.8mm; Hardness: $\ge$ 950 HV).

• Optional Bimetallic Coating: Tungsten carbide alloy cladding for aggressive abrasive processing.

2. Multi-Vent Vacuum Degassing Architecture

Residual moisture, trapped air, and ink volatiles degrade the mechanical properties and appearance of reprocessed granules.

• Single or double atmospheric/vacuum venting ports remove trapped gases continuously.

• High-vacuum pumps pull moisture and volatiles out before the melt reaches the filter screen.

3. Continuous Hydraulic Filtration

• Dual-bolt or plate-type hydraulic screen changers allow rapid mesh filtration changes.

• Large filtration area reduces back-pressure and ensures smooth plasticization.

4. Energy-Saving Heating & Drive Systems

• Energy-efficient helical gearboxes with forced lubrication for whisper-quiet, low-vibration operation.

• Ceramic band heaters wrapped in thermal insulation covers reduce heat loss and electrical power draw by up to 20%.

High-Turbulence Mixing Blades:

• Specially designed 3-tier dynamic blades (bottom sweeping, middle mixing, top folding blades) made from hardened alloy steel / SS 304.

• Ensures 100% uniform dispersion of color masterbatches, liquid pigments, calcium carbonate ($\text{CaCO}_3$) filler, and anti-static additives without dead zones.

Heavy-Duty Vessel Construction:

• Inner tank fabricated from heavy-gauge SS 304 mirror-polished stainless steel to prevent material sticking and allow quick color changes between batches.

• Double-jacketed construction (optional) for water cooling or electric oil heating when moisture pre-drying is required.

Dust-Proof & Airtight Sealing:

• Pneumatically sealed top lid prevents powder leakage during high-RPM friction mixing.

• Mechanical shaft seal ensures fine pigments and filler powders do not leak into the bearings.

Safety & Automation Controls:

• Safety Interlock Switch: Machine will not start if the top cover lid is open.

• Digital Timer & Ammeter: Preset mixing cycles for consistent batch-to-batch color blending and prevent motor overloading.

• Synchronized Feed Control: Variable Frequency Drive (VFD) adjusts the roller feed speed to match the extruder speed, ensuring consistent pellet length.

• Precision Rotary Cutter: Multi-tooth HSS/Carbide cutter blades give clean, dust-free cuts without stringy edges or granule tearing.

• Quick Blade Adjustment: Tool-less / micro-adjustable bed knife setting for fast maintenance and gap alignment.

• Low Noise & Vibration: Heavy Cast Iron / MS channel frame base with soundproof protective hood.
