Service Overview
Service Overview
Defects always mean financial losses
The cause is rarely obvious: it may be a hidden raw-material defect, incorrect temperature control, or polymer degradation caused by improper drying
We conduct an independent analysis to identify the true source of the problem and provide clear corrective instructions
For whom:
Production managers, process engineers, and quality control departments
Service Formats:
Product brittleness, warpage, specks or streaks, silver streaking, short shots, or flash
Types of Analysis
We classify and investigate defects in three areas:
Raw Material Factor
Checking for incompatible contaminants, excessive moisture, or polymer degradation during storage
Process Factor
Analysis of the material’s thermal history, including overheating or insufficient heating, and the effect of cooling conditions on product structure
Engineering Factor
Assessment of how mold design or screw-barrel configuration contributes to internal stresses in the material
Methodology and Standards
Diagnostics are performed by elimination using laboratory testing
Optical Analysis
Microscopic examination of fracture zones and cross-sections
Thermal Analysis (DSC)
Determination of crystallinity and detection of thermal degradation
Resistance Testing
Testing products under load to identify internal stress zones
Instrumentation and Facilities
-
High-resolution digital microscopes for macro and micro imaging of defects
-
Laboratory drying ovens and moisture meters for evaluating hygroscopicity
-
Equipment for preparing microsections
