Medical Plastic Project 6.5Ton Injection Molding Machine

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
