The processing technology of plastic molds is a complex and delicate process involving multiple steps and professional technical knowledge. The following is the main process flow of plastic mold processing:

1. Design phase: This is the first step in plastic mold manufacturing, requiring mold design based on product needs and design drawings. Design considerations include product shape, size, material, and shrinkage rate.

2. Mold material selection: Selecting suitable mold materials is key to manufacturing high-quality molds. Commonly used materials include steel and aluminum alloys; the appropriate material must be selected based on product needs and design.

3. Mold manufacturing preparation: Includes preliminary work such as material cutting, grinding, and heat treatment to ensure the basic shape and structure of the mold meet design requirements.

4. Mold machining: This is the core part of the manufacturing process and includes milling, drilling, and grinding. These operations require high-precision equipment and technology to ensure mold accuracy and durability.

5. Mold assembly and debugging: After processing all parts, assembly and debugging are required. This step requires meticulous operation to ensure that all parts of the mold can precisely cooperate to achieve the purpose of plastic molding.

6. Mold trial and acceptance: After mold assembly and debugging, mold trials are necessary. The purpose of mold trials is to check the performance and quality of the mold to ensure that the produced plastic products meet design requirements. After successful mold trials, the mold can be accepted and put into use.

7. Maintenance: During use, regular maintenance of the mold is required to ensure its lifespan and performance. Maintenance includes cleaning, lubrication, and inspection.

For plastic molds of a specific length, such as molds reaching 600mm in length, the following points should be noted:

1. During design and manufacturing, the rigidity and stability of the mold must be considered to ensure that it does not deform during high-pressure molding.
2. For large molds, high-precision processing equipment and technology are required to ensure mold accuracy and surface quality.
3. During mold trials and acceptance, special attention should be paid to the molding effect and dimensional accuracy of the product to ensure that the produced plastic products meet design requirements.
