How to analyze the machined surface of the pen mold

The analysis of the machined surface of the pen mold mainly involves a comprehensive evaluation of the quality, hardness, wear resistance, roughness and possible defects of the mold surface. Here are some key analysis steps and considerations:

1. Surface quality assessment:

Observation and inspection: Through visual observation or the use of tools such as a microscope, check whether there are cracks, porosity, inclusions and other defects on the surface of the mold.

Roughness measurement: Use a roughness measuring instrument to measure the roughness of the mold surface to ensure that the surface roughness meets the design requirements.

2. Hardness and wear resistance test:

Hardness test: Use a hardness tester to test the hardness of the mold surface to determine whether its hardness value meets the requirements of use.

Abrasion resistance assessment: By simulating actual working conditions, the surface of the mold is tested for wear to evaluate its wear resistance.

3. Analysis of chemical composition and metallographic structure:

Chemical composition analysis: Through chemical analysis or spectroscopic analysis, the chemical composition of the mold surface is determined to ensure that it meets the design requirements.

Metallographic structure observation: Use metallographic microscope to observe the metallographic structure on the surface of the mold to understand the uniformity, grain size and other characteristics of the structure.

4. Analysis of processing traces and killing stress:

Processing trace inspection: observe whether there are obvious processing marks on the surface of the mold, such as knife marks, grinding marks, etc

Residual Stress Measurement: Use the residual stress measuring instrument to measure the residual stress on the surface of the mold to understand the distribution of residual stress generated during the machining process and its impact on the performance of the mold.

5. Functional Assessment:

Mold release performance: Evaluate the mold release performance of the mold surface to ensure smooth mold release during the production process.

Surface lubricity: Analyze the lubrication properties of the mold surface to reduce friction and damage during the production process.

6. Comparative Analysis:

Compare with standard or sample: Compare the results of the analysis of the mold surface with the standard or sample to assess the degree of compliance.

Comparison of different batches or different processing methods: compare the quality differences of the mold surface under different batches or different processing methods, and provide a basis for optimizing the processing technology.
