Overview
Laser direct molding (LDS) technology is a new 3D molding technology that integrates functional material modification, injection molding, laser activation, and self. Catalytic electroless plating and other processes, and endows the surface of functional plastic-modified material with functions such as functional antenna and conductive path. LDS functional material series products have the characteristics of easy molding processing, simple manufacturing process, fast plating, and high freedom of product design, and can be widely used in electronic communications, electronic appliances, medical services, automotive, aviation, and safety fields. The LDS material developed by Shanghai Institute has completed the laboratory composition design and modification research and successfully achieved an 80kg/scale-up test.
LDS functional material modification
LDS functional modified materials with ABS, PC, PA, PBTPBT, PPS, Pl, and other general and engineering plastics as the substrate, including a number of series of grades, can meet the needs of different performance applications. According to customers' needs, LDS functional materials with special requirements can also be customized and developed. LDS series of functional modified materials have the characteristics of excellent flow and processing properties high heat resistance, good photo-aging stability, excellent mechanical properties, etc., and the comprehensive performance reaches or even exceeds that of commercially available imported products.
It also has the following characteristics:
The impact toughness is increased by about 2 times, and the fluidity and heat resistance are equivalent;
Mechanical strength and modulus meet application requirements.
Laser activation process
The LDS functional modified material can optimize the activation process by adjusting the laser activation parameters and LDS functional auxiliary system, and accurately control the microstructure of the activation region in the resolution range of 300-2000dpi.
Autocatalytic electroless plating process
Self-catalytic electroless plating is green, fast plating, uniform and controllable coating; Under the conditions of industrial application evaluation of double 85, the structure has strong adhesive force, and is above grade 4Bof 100 grid evaluation, with high reliability.
Promotion and Application
DS functional materials were evaluated by Shandong GoerGroup, Dongguan Jirui Electronics, Shenzhen WeihangTechnology, Dongguan Jiahan, and other companies. At present, it has been successfully applied to mobile phone antennae, mobile phone frames, mobile phone brackets, smartwatch cases, and other terminal applications in Dongguan Jirui Electronic Technology Co., LTD., Shenzhen Micro Hang Technology.
