Founded in 2006, SZZN Precision Machinery Group focuses on the development of magnesium and aluminum alloys, ceramics, glass, stainless steel, touch screens, titanium metal materials, and high-end precision parts and components for watches and clocks based on scientific materials and precision engineering technology. There is a company in the UK that masters core technologies such as touch panels and metal injection molding, and is in a leading position in the industry.
Production and processing processes include Conventional Metal Processing & Precision Stamping, Metal Injection Molding, Window Display, Touch Panels and Decorative Coating together with Functional Coating business.
Continuous investment in R & D is one of main reasons of our success. Apart from setting up R & D center in China, USA, UK, and Switzerland, we also cooperate with the University of Oxford and The Hong Kong University of Science & Technology on various R & D projects .
Main production sites spread across the Mainland China, including Shenzhen, Guangzhou and Suzhou, employed with over 11,000 employees.
Precision Metal processing
Precision metal processing is the production of highly precise metal parts using several forming and surface treatment technologies, including metal stamping, hot and cold forming and surface forging, CNC machining and surface finishing (polishing, hairline brushing and sand blasting).
Our precision metal processing capabilities can produce components with tolerances of 20 microns. We also produce metal casings and components for renowned watch makers, branded smart device vendors and smart device contract manufacturers using precision metal processing technologies. We currently manufacture metal casings and components by using different substrate materials, including aluminum, stainless steel, titanium, zirconium, gold, silver and metal matrix composite.
We offer a range of metal forming technologies that complement our MIM technology to provide a complete one-stop service to satisfy customer needs.
Stamping (Progressive / Compound)
Forging (Hot / Cold)
CNC Producing difficult features and high accuracy
Lasering, Welding
Lasering text, pattern & Assembly with 2 metals
Metal Injection Molding
Metal Injection Molding (“MIM”), is a forming technology that is typically used to create small, thin, light and / or complex mental parts with certain desired metal properties for use in a variety of industries and applications. MIM is often used by customers who require metal parts to be of a precise size, shape, weight and durability for functional or aesthetic reasons and in large volumes.
Application of MIM techniques to powder metallurgy (for metals and alloys with higher melting points, such as stainless steel and titanium) or metal rods through metal injection (for metals and alloys with lower melting points, such as magnesium and aluminum). MIM has the following advantages over other similar production processes:
greater complexity, thinness, hardness, density and design flexibility, particularly for smaller sized components;
better mechanical properties and strength compared with CNC machining and casting;
more efficient than CNC machining, as less waste material is generated during the process, much of which can be recycled or re-used;
better surface finishing compared with casting and traditional forging;
wider application to various metals and advanced materials, such as ceramics.
We produce metal Touch and Look components for smart devices, including metal casings of complex shapes and precision metal components such as bezels, buttons and trims. We also produce precision metal watch components, bands and cases, as well as bracelets, jewelry parts and metal parts for automobiles, eyewear, cameras and medical equipment, such as parts for hearing aids and microsurgical instruments.
We are able to use MIM to more efficiently manufacture products which are lighter, thinner, harder and / or more precise than components made through other processes such as CNC machining. Our MIM capabilities can produce components with tolerance of 2 microns, which reduces the need for secondary processing.
We are also able to apply MIM and surface treatment processes to magnesium and aluminum components, which we believe few other companies can do.
