Applicable Materials
✅ Suitable Materials
PETG, PLA, ABS, and other thermoplastic pellets/crushed materials with melting point ≤300℃
❌ Not Suitable Materials
Materials with melting point over 300℃, high-hardness materials, highly corrosive materials, and any materials containing hard impurities (metal, sand, etc.)
Material Pre-Treatment Guide (Critical for Smooth Extrusion)
Proper material preparation ensures perfect extrusion effect and protects the machine from damage. Please follow these steps strictly:
- Crushing & Impurity Removal: All materials must be crushed into particles with diameter ≤3mm; thoroughly remove iron scraps, sand, dust and other hard impurities to avoid screw damage.
- Strict Drying Requirement: All materials MUST be dried before use, otherwise a large number of bubbles will appear in extruded products. Dry until humidity ≤20%, with drying time no less than 6 hours.
Mandatory Safety & Operation Rules
Non-Negotiable Safety Notes – Follow these to avoid injury and machine damage:
- DO NOT start the motor/screw until the temperature rises above 220℃ – low-temperature startup will damage the screw and barrel.
- Crushed material particle size must NOT exceed 3mm, as oversized particles will cause blockage and motor overload.
- Never touch the heating barrel, screw or discharge port with bare hands during operation – high temperature will cause severe burns.
- Unplug the power supply before cleaning, nozzle replacement or maintenance.
Wide Application Scenarios
- Lab material testing and formula development for thermoplastics
- Small-batch plastic sample making and prototype production
- Waste plastic recycling and re-extrusion (reduce material waste, save cost)
- DIY plastic processing and small-scale creative production
