• Popular Models: CX, PX Series (e.g., CX 200-750).

• Best For: Automotive parts, appliance housings.

(2) Japan (Reliable, Energy-Efficient)

• Fanuc (ROBOSHOT)

• Key Features: All-electric, high speed & precision.

• Popular Models: α-S Series (e.g., α-S50iA).

• Best For: Thin-wall molding (phone cases, optical lenses).

• Toshiba

• Key Features: Fast cycle times, stable performance.

• Popular Models: EC-SX Series (e.g., EC-40SX).

(3) Other Global Brands of Injection molding machine

• ENGEL (Austria): Best for large molds & multi-color molding.

• Husky (Canada): Specializes in packaging (bottle caps, closures).

• Milacron (USA): Mid-range, cost-effective solutions.

2. Top Chinese Brands (Cost-Effective Alternatives)

(1) Haitian (HAITIAN)

• Market Position: World’s largest manufacturer by volume.

• Popular Models:

• MA Series (Standard hydraulic, e.g., MA1200)

• JU Series (Two-platen, space-saving, e.g., JU2000)

• Zhafir (All-electric): ZE Series (e.g., ZE800)

• Best For: Consumer goods, household products.

(2) Yizumi (YIZUMI)

• Key Features: Near-European quality at competitive prices.

• Popular Models:

• A5 Series (High-performance, e.g., A5-1580)

• FE Series (All-electric, e.g., FE-120)

• Best For: Automotive, electronics.

(3) Other Notable Chinese Brands of Injection molding machine

• Borche: Smart IoT-connected machines.

• Terry: Strong in two-platen machines for large parts.

• LK Technology: Good for mid-range applications.

3. Key Selection Criteria

(1) Clamping Force (Tons)

• Rule of Thumb:

• Clamping Force ≥ Projected Area (cm²) × Material Pressure (30-50 MPa)

• Example: A 500 cm² ABS part requires 50–80 tons.

(2) Injection Capacity (g/shot)

• Should be 1.5–2× the part weight to avoid short shots.

(3) Drive System

• Hydraulic: Cheaper, good for large parts.

• All-Electric: High precision, energy-efficient (best for medical/electronics).

• Hybrid: Balances speed and energy consumption.

(4) Special Requirements

• Multi-Material Molding: Requires rotary table (e.g., Arburg 630T).

• High-Speed Thin-Wall: Look for fast injection rates (e.g., Toshiba EC-SX).

4. Industry-Specific Recommendations

5. Buying Tips

✔ Request a Test Run: Verify machine stability and energy efficiency.
✔ Check Local Support: Choose brands with strong after-sales service (e.g., Haitian has wide coverage in China).
✔ Future-Proofing: Ensure compatibility with automation (robots, IoT).

Final Thoughts

• Budget + General Use → Haitian MA / Yizumi A5

• High Precision + All-Electric → Fanuc / Haitian Zhafir ZE

• Large Automotive Parts → KraussMaffei CX / Terry Two-Platen

The best injection molding machine depends on your specific needs. Compare technical specs, test machines, and consult experts before deciding.
