In the competitive world of blow molding and rigid packaging, choosing the right preform mold is critical for balancing output, quality, and operational cost. For manufacturers specializing in wide-mouth PET containers—such as food jars, supplement pots, and tamper-evident packaging—the GTW 10-cavity PET wide-mouth preform mold represents an optimal solution for medium-to-high volume production lines.
Why Choose a Dedicated Wide-Mouth PET Mold?
Unlike standard beverage preforms, wide-mouth preforms require distinct neck designs, thicker walls, and specialized cooling profiles. GTW has engineered its 10-cavity mold specifically to address these challenges, ensuring:
Consistent wall thickness for uniform blow-molding results.
Stress-free neck finishes that maintain sealing integrity.
Faster cycle times thanks to optimized cooling channel design.
Key Features of the GTW 10-Cavity Wide-Mouth Mold
1. Precision-Engineered 10-Cavity Layout
The 10-cavity configuration offers a "sweet spot" for many processors: higher output than 4 or 8 cavity molds, yet more manageable than 16 or 32 cavity systems. It is ideal for:
Small to medium production runs.
Just-in-time (JIT) manufacturing environments.
Facilities with injection molding machines clamping forces between 160–300 tons.
2. Superior Cooling for Faster Cycles
GTW utilizes conformal cooling channels and stainless-steel plates to achieve:
20–30% shorter cooling time compared to generic molds.
Reduced part warpage and shrinkage.
Higher cavitation utilization without quality loss.
3. Wide-Mouth Specific Design
Neck diameters typically range from 38 mm to 120 mm. The mold supports:
Jam jar finishes (continuous threads).
Lug-type caps for easy-open lids.
Tamper-evident band compatibility.
4. Durable Construction
Made from high-grade stainless steel (e.g., S136, 2316) and heat-treated components, the GTW mold ensures:
5+ million shots between major maintenance.
Corrosion resistance for recycled PET (rPET) processing.
Interchangeability with major injection systems (Husky, Netstal, Sumitomo, etc.).
