The production process of Amino Molding Plastic (AMP) involves a series of specialized steps to achieve its thermosetting properties and structural integrity. Below is a detailed breakdown:
Material Preparation
Raw materials, including amino resins (synthetic thermosetting polymers), fillers like paper pulp, and additives (e.g., catalysts or pigments), are carefully measured and prepared. The resin is typically derived from reactions between amino compounds and aldehydes such as formaldehyde16.
Mixing and Kneading
The prepared materials undergo thorough mixing to ensure homogeneity. This step may include kneading to integrate fillers and additives evenly into the resin matrix, forming a pliable compound6.
Granulation
The mixed compound is processed into granular form through extrusion or pelletizing machines. Granulation enhances material flowability and ensures consistency for subsequent molding stages6.
Pre-pressing
Granules are pre-compressed into preforms or blanks under moderate pressure. This step facilitates easier handling and precise placement in molds during the final molding phase1.
Hot Press Molding
Preforms are transferred to heated molds and subjected to high temperature (120–160°C) and pressure. The thermosetting resin undergoes cross-linking, solidifying into the desired shape. This step is critical for achieving dimensional stability and mechanical strength15.
Curing and Post-processing
The molded product is cooled and cured to complete the polymerization process. Post-processing steps, such as trimming, surface polishing, or coating, may be applied to meet specific functional or aesthetic requirements1.
This streamlined process ensures AMP’s adaptability to diverse industrial applications while maintaining its eco-friendly profile through efficient material utilization
