Professional Process of LEIZHEN Mould in Manufacturing Preform Molds

Introduction

LEIZHEN Mould is a leading manufacturer specializing in high-quality preform molds for the PET packaging industry. With advanced technology and strict quality control, LEIZHEN ensures precision preform mold manufacturing for optimal performance in bottle production. This article explores the professional process of LEIZHEN Mould in crafting durable and efficient preform molds.

Step-by-Step Manufacturing Process

1. Design & Engineering

LEIZHEN Mould begins with custom preform mold design, using CAD/CAM software to ensure accuracy. Engineers optimize the mold structure for high-speed injection molding, considering factors like cooling efficiency and material flow.

2. Material Selection

Only high-grade steel alloys (e.g., H13, Stainless Steel) are used to ensure durability and corrosion resistance in preform mold production.

3. CNC Machining & EDM

Advanced CNC machining and Electrical Discharge Machining (EDM) create precise mold cavities and cores, ensuring tight tolerances for consistent preform quality.

4. Heat Treatment & Surface Finishing

The molds undergo heat treatment to enhance hardness and longevity. Polishing and coating (e.g., chrome plating) improve surface smoothness and reduce wear.

5. Assembly & Testing

Each mold is meticulously assembled and tested in injection molding machines to verify performance, cycle time, and preform quality.

6. Quality Inspection

Strict quality control measures, including dimensional checks and pressure testing, ensure every preform mold meets industry standards.
