The purpose of pretreatment is to improve the processing performance and surface quality of the material and prepare it for subsequent processing.

Rough processing

1. CNC processing

The rough processing stage is mainly carried out using CNC machining centers.

According to the design drawings, write CNC programs and control the tool for preliminary processing. The purpose of rough processing is to remove excess material 

and form the basic shape of the mold.

2. EDM

For the processing of some complex shapes or hard materials, an EDM machine can be used.

EDM removes materials and realizes the processing of complex shapes through the discharge between the electrode and the workpiece.

3 . Wire cutting

The wire cutting machine is also one of the important pieces of equipment for rough processing.

It cuts the workpiece through the electrode wire and is suitable for processing mold parts with complex shapes and high-hardness materials.

Heat treatment

1. Heat treatment process

After the rough processing is completed, the mold needs to be heat-treated.

The purpose of heat treatment is to improve the hardness, strength, and wear resistance of the material. Common heat treatment processes include quenching, 

tempering, and carburizing.

2. Heat treatment equipment

The equipment used in the heat treatment process mainly includes a quenching furnace, tempering furnace, and carburizing furnace.

Select appropriate heat treatment processes and equipment to ensure that the performance of the mold after heat treatment meets the requirements.

3. Heat treatment inspection

After the heat treatment is completed, the mold needs to be inspected.

Mainly inspect the hardness, structure, and deformation of the mold to ensure that the heat treatment effect meets the design requirements.

Finishing

1. Precision Grinding

During the finishing stage, grinding machines are mainly used for precision grinding.

The purpose of grinding is to improve the dimensional accuracy and surface quality of the mold. During the grinding process, the processing parameters need to be 

strictly controlled to ensure that the mold surface is smooth and flat.

2. Polishing

Polishing is one of the important steps in finishing. The mold surface is polished by a polishing machine to improve the surface finish and aesthetics.

The polished mold surface should achieve a mirror effect without obvious scratches and flaws.

3. Precision machining

For some high-precision and complex-shaped mold parts, precision machining is also required.

CNC machining centers, EDM machines, wire cutting machines, and other equipment can be used for precise secondary machining to ensure dimensional accuracy and 

shape accuracy of the mold.

Mold assembly 

1. Part preparation

After finishing, the various parts of the mold need to be prepared. Including cleaning, deburring, and inspecting parts to ensure that the surface of the parts 

is smooth and defect-free.

2. Assembly process

According to the design drawings, the various parts are assembled according to a certain assembly process.

Special tools and equipment are required during the assembly process to ensure that the parts fit tightly and are positioned accurately.

3. Assembly inspection

After the mold is assembled, an assembly inspection is required. It mainly inspects the assembly accuracy of the mold, the fit of each component, and the overall 

structure of the mold. After the assembly inspection is passed, the mold enters the debugging stage.

Mold debugging

1. Debugging preparation

Before mold debugging, debugging preparation is required. Including the preparation of debugging equipment, the writing of debugging programs, and the formulation 

of debugging plans.

The purpose of debugging preparation is to ensure that the debugging process goes smoothly.

2. Debugging process

During the mold debugging process, the mold needs to be tested and the working condition of the mold needs to be checked.

During the debugging process, various parameters of the mold need to be adjusted to ensure that the mold can work normally and produce qualified products.

3. Debugging inspection

After the mold is debugged, a debugging inspection is required. It mainly inspects the working performance, product quality, and production efficiency of the mold. 

After the debugging inspection is passed, the mold enters the acceptance stage.

Mold acceptance

1. Acceptance criteria

Before mold acceptance, detailed acceptance criteria need to be formulated.

The acceptance criteria should include indicators such as the mold's dimensional accuracy, surface quality, working performance and service life to ensure that the 

mold meets the design requirements.

2. Acceptance process

According to the acceptance criteria, the mold is fully inspected. Professional inspection equipment and tools are required during the acceptance process to ensure 

that the inspection results are accurate and reliable.

3. Acceptance report

After the acceptance is completed, a detailed acceptance report needs to be written.

The acceptance report should include various inspection results and usage suggestions of the mold, and provide customers with comprehensive mold information.

Mold delivery

1. Packaging and transportation

After the mold is accepted, it needs to be packaged and transported.

Shockproof and moisture-proof packaging materials need to be used during the packaging process to ensure that the mold is not damaged during transportation.

During transportation, it is necessary to choose a suitable transportation method and route to ensure that the mold is delivered to the customer on time.

2. Customer training

After the mold is delivered, the customer needs to be trained. The training content should include the use of the mold, maintenance and common fault handling, 

etc., to ensure that the customer can use and maintain the mold correctly.
