After plastic injection mold manufacturing is complete, the KRMOLD team conducts a rigorous testing process. These tests primarily focus on physical properties testing, chemical properties testing, and visual inspection.
-Physical properties testing of plastic injection molds
Physical properties testing is a key step in evaluating the strength and durability of plastic injection mold materials. It primarily encompasses the following aspects:
1. Strength Testing: This includes tensile strength and flexural strength, used to assess the plastic injection mold's ability to withstand compression under load.
2. Hardness Testing: This involves measuring the hardness of the plastic injection mold material using a Rockwell or Barcol hardness tester, which directly impacts its wear resistance and service life.
3. Toughness Testing: This is typically performed using an impact test to assess the fracture toughness of the plastic injection mold material under impact loads.
-Chemical properties testing of plastic injection molds
Chemical properties testing primarily ensures the stability and chemical resistance of the plastic injection mold material. Common test items include:
1. Heat Resistance Testing: This assesses the plastic injection mold material's stability and deformation in high-temperature environments.
2. Corrosion Resistance Testing: This tests the plastic injection mold material's resistance to corrosion in chemically corrosive media.
3. Aging Resistance Test: This test simulates long-term use conditions to determine the degree of aging and performance degradation of the plastic injection mold material.
- Plastic injection mold visual inspection
Visual inspection is a crucial step in ensuring the surface finish and molding accuracy of plastic injection molds. Common inspection items include:
1. Surface Roughness Test: This test uses a surface roughness tester to measure the surface roughness of the plastic injection mold, which directly impacts the product's appearance quality. 2. Dimensional Measurement: This test uses equipment such as a coordinate measuring machine to measure the precise dimensions of the plastic injection mold to ensure it meets design requirements.
3. Molded Part Inspection: This test inspects molded parts for defects, dimensional deviations, and other visual defects.
