With the continuous development of high-performance engineering plastics, nylon(PA) injection molding has become a material revolution in modern manufacturing. This article first introduces the innovations in plastic injection molds factory related to nylon molding, then explores the critical role of medical injection molding in medical device production, and finally analyzes the key points and quality control in the manufacturing of high precision plastic parts. The three main keywords are naturally and consistently interwoven throughout the article to highlight nylon’s outstanding advantages in flowability, strength, and precision.
Nylon is a synthetic polymer composed of polyamide (PA), first invented in 1935 by Wallace Carothers and his team at DuPont, and commercialized in 1938. It exhibits the following characteristics:
High strength and toughness: With tensile strength reaching 75–85 MPa and elongation at break between 50–300%, nylon performs exceptionally well in high precision plastic parts and plastic injection molds factory applications.
Excellent wear and fatigue resistance: Standard friction tests show a wear rate of less than 0.1 mg/N·m, and fatigue life can exceed 10^6 cycles, making it ideal for gears and rollers.
Chemical resistance: Nylon shows less than 5% weight loss when exposed to common oils, phenols, and alcohols, meeting the strict requirements of medical injection molding for biomedical materials.
Outstanding heat resistance and dimensional stability: With a heat deflection temperature of 100–120 °C and a thermal expansion coefficient of about 80×10^−6 /K, it maintains dimensional accuracy in high-temperature processes in plastic injection molds factory settings.
