Product Overview

For Corporate R&D Centers, University Labs, and QA/QC Departments This industrial-grade precision laboratory pelletizer allows engineers to conduct formulation trials, color matching, and polymer modification testing using minimal raw materials (500g to 1kg), preventing the waste of expensive resins while ensuring data consistency for scaling up to mass production.

Core Technical Advantages

Research-Grade Precision Temperature Control
Features individual heating zones with an advanced intelligent PLC system, maintaining temperature fluctuations within plus/minus 1°C up to 350°C (optional 400°C+ for high-performance engineering plastics). This prevents polymer degradation during residence time.

Modular Screw & Barrel Flexibility
The segment-designed screw elements (conveying, kneading, shearing blocks) can be easily reconfigured to match different polymer rheological properties, optimizing dispersion and compounding efficiency for specific formulations.

Zero Cross-Contamination & Quick Cleaning
Engineered with a split-barrel (clam-shell) option or quick-disassembly structure. Allows laboratory operators to visually inspect the compounding process and thoroughly clean the screw within minutes during material or color switches.

Compliance with Global Standards
Built in strict compliance with CE safety protocols. All electrical components feature international brands (Siemens, Schneider, Omron, Delta) ensuring stable 24/7 continuous operation and easy local maintenance worldwide.

Professional Applications & Test Cases

Our lab pelletizing machines are optimized for precision compounding trials conforming to ASTM/ISO standards:
Biodegradable Plastics (PLA, PBAT, Starch compounding): Precise shear control prevents thermal degradation of sensitive bio-polymers.

Engineering Plastics & Nano-composites (PA, PC, PET + Carbon Fiber/Graphene): High-torque output ensures uniform dispersion of nano-additives and glass fibers.

Functional Masterbatch & Color Matching (PE, PP + High-pigment loading): Achieves industrial-grade pigment wetting and homogenization on a miniature scale.

Typical Lab Test Case:
Material: Recycling PET Flakes + Anti-hydrolysis Additive Compound

Objective: Re-granulation to test IV (Intrinsic Viscosity) retention.

Result: Pellets achieved highly uniform dimensions (2.5 mm ± 0.1 mm), zero air bubbles, perfect for physical property testing bars injection.

One-Stop Advantage: From Crushing to Pelletizing

Unlike specialized lab-only traders, is a verified manufacturer of industrial recycling lines (fully automatic crushing and washing production lines, shredders, and hydraulic balers). We understand the practical challenges of plastic recycling. We can provide a Full Lab-Scale Recycling Pipeline-matching this precision pelletizer with our Mini Lab Crusher and Washing Unit-allowing you to simulate the entire industrial recycling process right inside your laboratory.

FAQ

Q: Can your lab pelletizer handle heat-sensitive polymers or materials with a narrow processing window?

A: Yes. Thanks to the segmented barrel design and the precise PID temperature control (plus/minus 1°C by Omron/Siemens), we can design a specialized low-shear screw profile to prevent localized overheating, making it perfect for materials like PVC or PLA. We need to test formulations based on industrial recycled plastic flakes.

Q: Can this small machine feed them smoothly?

A: We offer an optional Force Feeder (Crammer Feeder) specifically designed for low-bulk density materials like regrind flakes, films, or powders. This ensures a constant, non-bridging material flow into the screw barrel.

Q: How do you verify the machine performance before shipping it to our country?

A: We implement a strict factory acceptance test (FAT). Before shipment, we can run a live video test using your specified material or a standard polymer. We will send you a comprehensive testing report, including pellet samples and video recordings of the machine in operation.

Q: What kind of international warranty and after-sales support do you provide?

A: We provide a 12-month structural warranty. For international clients, we provide detailed English manuals, installation videos, and 24/7 online video technical support. Since we use globally standardized components (Siemens, Schneider), replacement parts can also be sourced locally or dispatched via DHL express within 48 hours.
