NT120m Newly China Hot Sale Desktop Small Injection Moulding Machine for Moulding Machine Plastic Injection
Plastic Injeciton Molding Machine
Plastic Injection molding equipment consists of plasticizing system, injection system, the clamping system and transmission system. Our company has been applying die casting technologies to injection molding machines for many years, like in mechanical, hydraulic, electric control, etc for comprehensive improvement, perfect combination of dynamic pressure casting and speed.
In order to improve the stability of syringe production, we specially add infrared heating coil to standard injection molding machine. In addition, we recommend adding servo motor system, has the advantages of energy saving, in a long term production, it is more economic, so nowadays more and more companies choose servo motor system.

Injection Machine
1. High Clamping Force
Hydraulic or servo-toggle clamping system from 50 to over 3,000 tons.
2. Precision Injection Unit
Double-cylinder or screw-plunger design for accurate shot control (±0.1g).
3. High-Screw Plasticizing
Optimized screw geometry for fast melting and uniform melt temperature.
4. Energy-Saving Servo Pump
Variable-frequency drive reduces power consumption by 30–60% vs. fixed pumps.
5. Multi-Stage Injection
5–10 stage injection pressure and speed control for complex parts without flash.
6. Fast Mold Protection
Low-pressure mold protection with intelligent response to prevent mold damage.
7. User-Friendly Controller
Touchscreen with 100+ mold recipes, real-time monitoring, and self-diagnostics.
8. Rigid Toggle Linkage
Long-life, low-maintenance toggle mechanism for stable, repeatable clamping.

Q1: Short shot (incomplete filling). Causes?
Q2: Flash (burrs). How to remove?
Q3: Machine won’t start or stops suddenly. What to do?
Q4: Hydraulic oil leak or high temperature. How to handle?
Q5: Daily maintenance essentials?
A: Machine capacity too small, material bridging in hopper, nozzle blockage, or low melt temp. Increase capacity, clear hopper, clean nozzle, raise temp
