Description

Gutewei is a specialized manufacturing facility dedicated to the design and production of high-quality PET wide-mouth preform molds. With years of focused experience in the packaging mold industry, we have established ourselves as a reliable partner for clients seeking professional wide-mouth mold solutions.

Our Manufacturing Capabilities

State-of-the-Art Production Facility
Our factory is equipped with advanced manufacturing technology to deliver precision molds that meet the highest industry standards:

• 5-Axis CNC Machining Centers: For complex cavity geometries with exceptional accuracy

• High-Speed EDM Equipment: For precise detail work and fine surface finishes

• CMM Inspection Systems: For comprehensive dimensional verification of all mold components

• Deep-Hole Drilling Machines: For optimized cooling channel placement

• Polish and Finishing Workshop: For mirror-surface cavity finishes

Specialized Expertise in Wide-Mouth Applications

Wide-mouth preform molds require specialized knowledge that differs from standard beverage molds. Our engineering team possesses deep understanding of:

Neck Finish Design
We have extensive experience with all major wide-mouth neck finishes:

• Standard sizes from 38mm to 120mm

• PCO-style wide-mouth configurations

• JAR threaded finishes

• Snap-on closure designs

• Custom proprietary neck finishes

• Child-resistant closure compatibility

Preform Weight Management
Wide-mouth preforms typically range from 15g to 400g+. Our molds are engineered to handle the full spectrum:

• Lightweight (15g – 40g) for small jars and containers

• Medium-weight (40g – 90g) for standard food jars

• Heavy-weight (90g – 180g) for large containers

• Ultra-heavy (180g – 400g+) for industrial packaging and pails

Material Distribution Control
Wide-mouth containers require precise material distribution for proper performance. Our preform designs ensure:

• Uniform wall thickness for consistent stretching

• Optimized material in neck and support ring areas

• Proper base design for stability

• Enhanced barrier properties where needed

Our Technical Advantages

✓ Customized Mold Design
We don't believe in one-size-fits-all solutions. Every wide-mouth mold we produce is tailored to:

• Your specific preform design and specifications

• Your injection molding machine parameters

• Your production volume requirements

• Your target container performance characteristics

✓ Premium Material Selection
We use only the highest quality materials for long mold life:

• Cavities and Cores: S136 stainless steel, heat-treated to 48-52 HRC

Every mold undergoes rigorous inspection before leaving our facility:

• 100% CMM dimensional verification

• Hot runner temperature balance testing

• Cooling channel flow and pressure validation

• Sample preform production and analysis

• Neck finish gauging and thread verification

• Wall thickness distribution measurement
