Raw Material Selection
The production of lunch boxes starts with the selection of suitable raw materials. Commonly used materials include food-grade plastics, stainless steel, and silicone. Manufacturers need to ensure that the selected materials meet food safety standards and possess properties such as high temperature resistance and corrosion resistance to guarantee the safety and durability of the lunch boxes.
Design and Mold Making
After determining the material, the design work for the lunch box proceeds. Designers create products based on market demand and customer requirements, including shape, color, and function. Once the design is completed, the next step is mold making.
Injection Molding
After the mold is made, the production of lunch boxes enters the injection molding stage. This process heats the raw materials to a molten state and then injects them into the mold. After cooling and solidification, the initial shape of the lunch box is formed.
Post-Processing
Following the initial molding of the lunch box, post-processing may be required, including removing excess burrs, grinding edges, and surface treatment.
Quality Inspection
After the lunch box is completed, quality inspection is an indispensable step. Manufacturers need to conduct a comprehensive inspection of the products, including appearance, size, and materials, to ensure that each product meets quality standards.
Packaging and Transportation
After passing the quality inspection, the lunch box will be packaged. Good packaging not only protects the product during transportation but also enhances the brand image.
The production process of lunch boxes covers all aspects from raw material selection to finished product transportation. Understanding this process can help consumers better comprehend the production background of lunch boxes and provide a reference for companies when choosing partners. Selecting a manufacturer with a complete production process will ensure that you receive high-quality lunch boxes that meet market demand.
