Core Manufacturing Process: Precision Injection Molding and Thermoforming Technology

Guanzhong achieves a balance between structural strength, appearance performance, and large-scale production of disposable food containers through a dual-process system of precision injection molding and thermoforming.

Precision Injection Molding Process: Core Basis of Structural Food Containers

Precision injection molding is mainly used for PP food container production. Through high-precision molds and stable temperature control systems, plastic is injected into the mold cavity under high pressure and evenly formed, ensuring consistent product dimensions, stable structure, and clear edges. This process improves impact resistance, heat resistance, and stacking stability, suitable for food delivery transportation and microwave heating scenarios.

Thermoforming Process: Efficient Solution for Transparent Packaging

Thermoforming is mainly used for PET transparent food container production. PET sheets are heated and softened and then vacuum-formed to quickly shape the material into molds. This process provides high transparency, lightweight structure, and high production efficiency, widely used in salad boxes, fruit boxes, and cold chain food packaging.

Mold Design and Digital Engineering Optimization

Guanzhong uses CAD/CAM integrated design and flow simulation analysis technology to optimize product structures in advance. By simulating material flow paths, snap-fit structures, and stress distribution, structural rationality and molding success rate are improved while reducing mold opening risks and production losses.

Full-Process Quality Testing System

Before mass production, products must undergo drop tests, sealing tests, and heat resistance tests to verify transport impact resistance, leakage prevention performance, and high-temperature stability, ensuring reliable performance in real logistics and food service environments.
