220V Vertical Injection Molding Machine 1KW Pneumatic Desktop Plastic Moulding

40g Small Vertical Injection Molding MachinePneumatic Desktop Plastic Moulding Machine1000WHayWHNKN®Product Overview

This 40g compact vertical injection molding machine targets laboratory testing, sample prototyping and small-batch plastic component manufacturing. Equipped with vertical pneumatic drive architecture, it delivers stable injection performance with precise temperature control up to 350°C, suitable for research labs, prototype workshops and small-scale production lines.

Compatible with mainstream thermoplastics including PP, PC, ABS, PET and PVC. Independent digital displays for timing and dual-zone temperature regulation on the front control panel support quick parameter setup and real-time monitoring. 1-ton injection pressure and 40g maximum shot volume perfectly match small precision connectors, test specimens and prototype parts.

Space-saving vertical layout, transparent safety observation door and solid stainless steel structure deliver industrial-grade performance in desktop size. Built-in air preparation unit with pressure gauge and filter ensures clean, stable pneumatic supply; adjustable anti-vibration leveling feet guarantee stable operation on all work surfaces.

Minimal floor occupation with full injection molding functionality. Upright structure enables gravity feeding and easy mold access. Four heavy-duty rubber leveling feet reduce vibration and maintain precise mold alignment even on uneven countertops.

Transparent Safety Door

High-temperature resistant transparent window allows safe real-time process observation. Lock latch prevents accidental opening during operation; reinforced hinges extend service life with clean industrial appearance.

Stainless Steel Hopper

Corrosion-resistant mirror polishing hopper with 40g capacity. Funnel design ensures smooth pellet flow without bridging. Smooth inner surface avoids material adhesion and simplifies cross-material cleaning.

Precision Mold Mounting System

Support molds up to 200×200×210mm with adjustable clamping brackets. Precision machined flat base ensures high mold alignment consistency, effectively reducing flash and product defects.

Pneumatic Drive System

0.6mpa air cylinder outputs stable 1-ton injection force. Integrated air filter-regulator-lubricator stabilizes air supply and protects pneumatic components from contamination. Quick-connect air fitting for fast pipeline assembly.

Precision Injection Nozzle

Precision machined nozzle prevents melt leakage between cycles. 20mm piston with 150mm stroke provides stable filling for micro parts; perfect contact with mold sprue reduces raw material waste.

Intelligent Digital Control Panel

Separate digital displays for timing and dual-zone heating temperature. Adjustable 0~350°C heating range covers all common thermoplastics, with 0-9999s injection timing for diversified molding demands.

Adjustable Anti-Slip Feet

Threaded height adjustment for horizontal calibration on uneven floors. Rubber bottom pads eliminate sliding during injection stroke and protect worktop surface from scratches.

Quality Internal Components

Industrial grade solenoid valves, relays and wiring harnesses for long service life. Openable side/rear panels simplify maintenance and fault diagnosis with clearly labeled wiring terminals.

[Wide Material Compatibility]: Supports PP, PC, ABS, PET, PVC and other thermoplastics; RT-350°C adjustable heating range meets laboratory and prototype production needs.

[Comprehensive Safety Protection]: Interlock transparent safety door, obvious warning labels, emergency reset function; machine stops automatically once door opens to guarantee operator safety.

[Energy-Efficient Operation]: 1000W low power consumption, digital constant temperature control reduces temperature fluctuation and power waste.

[User-Friendly Interface] Independent digital display for timing and temperature, labeled physical buttons minimize operation learning cost.

[Durable Construction] Heavy steel frame, stainless steel feeding hopper, precision injection assembly and industrial pneumatic parts ensure stable long-term workshop operation.

Operation Method

1. Equipment Placement & Connection
Place machine on flat stable workbench and adjust leveling feet for horizontal balance. Connect grounded 220V power supply; link air compressor with pressure ≥0.6mpa, check all pipelines for tightness.

2. Mold Installation
Open safety door, fix mold on mounting platform with adjustable brackets, align mold sprue with injection nozzle, lock safety door tightly.

3. Parameter Setting & Preheating
Switch on main power, set target heating temperature according to raw material property via digital thermostat, press Heat button to preheat until temperature stabilizes.

4. Feeding & Injection Molding
Pour plastic pellets into stainless steel hopper after temperature stabilization, set injection cycle time on timer, press Start to activate pneumatic injection cycle and fill molten plastic into mold cavity.

5. Cooling & Demolding
Wait for plastic cooling solidification based on material characteristics, open safety door and take finished product out for quality inspection, close door for repeated production.

6. Shutdown Process
Press Reset then cut main power after batch production completes; wait heating chamber full cooling before cleaning or maintenance.

Safety Precautions

WARNING: Read all safety specifications before operation. High temperature components and moving mechanisms may cause personal injury.

1. High Temperature Risk: Heating chamber and nozzle reach max 350°C during operation. Do not touch hot components when powered or just shut down; wait complete cooling before maintenance access.

2. Grounding Requirement: Must connect machine to standard grounded 220V socket, do not use ungrounded conversion plugs or extension cords.

3. Pneumatic Pressure Control: Regulate air supply within rated 0.6mpa maximum, cut air pipeline before pneumatic component maintenance.

4. Safety Door Interlock: Forofferden to run machine with unlocked safety door; door interlock is mandatory safety protection instead of auxiliary facility.

5. Moving Part Hazard: Keep hands, loose clothes and long hair away from injection piston and all moving assemblies during cycle operation.

6. Ventilation Demand: Maintain good workshop ventilation, exhaust equipment required for materials releasing volatile fumes under heating.

7. Workbench Standard: Place machine on flat heat-resistant platform with load capacity ≥150kg, clear all combustible materials around equipment.

8. Operator Qualification: Only trained staff familiar with injection molding process and safety rules can operate this machine; keep irrelevant personnel away during running status.

9. Maintenance Regulation: Cut power and air supply, wait full cooling before cleaning, component replacement or troubleshooting.

10. Personal Protection: Wear heat-resistant gloves and safety goggles when handling hot molds or molten plastics; unattended heating is strictly prohibited.
