Today's product designers are under the pressure of the UN initiative, the sustainable development goals (SDGs), and environmental protection laws and regulations in various countries. When choosing materials, how to balance product function and environmental protection laws and regulations has become an irreversible trend. In particular, the global Top 500 companies in the world have begun to build green supply chains, including TSMC, Apple, General Motors, P&G, and others. Recycled materials and biomaterials are more and more becoming highly favored by companies all around the world. However, when designing products, how do designers choose the right environmentally friendly materials for key parts from the many materials available? At the same time, product designers must also avoid risking the overall quality of the product. As such, evaluating environmentally friendly materials has become a challenging priority for many companies. In view of this, Chain-Ray’s extensive material database has a detailed material property table, which can help customers to evaluate raw material composition, physical properties, and material safety information in an efficient manner. At the same time, Chain-Ray can analyze which environmentally friendly materials are most appropriate and make samples for customers to further understand the impact of these materials on the overall product function and quality.

Aerospace, ships, railways, MRT, light rail, buses, automobiles, trains -- each form of transportation contains many different components. These components are related to human life and safety, meaning there is no margin for error. When choosing materials within these industries, special attention must be paid to whether the material has properties such as fire resistance, corrosion resistance, and heat resistance. Take a car as an example. A car is mainly composed of components made of metal and non-metal materials. However, metals are prone to oxidation and corrosion, which not only affects the appearance of the product, but more importantly poses a threat to safety. Naturally, national laws and regulations require that a car must undergo corrosion resistance testing, and even goes into details like whether the wiper placed on the car windshield affects the driver’s line of sight. When selecting materials for these products, there must also be anti-corrosion and resistance to temperature differences considered.

Products in the medical field are closely related to people's lives. For this reason, the standards for medical-related products in every country are quite rigorous and complicated. Whether the products are disposable medical consumables, repetitive medical instruments, containers used in laboratories, maintenance of medical personnel protection equipment, medical aids to help the disabled, or others, the correct medical materials should be carefully selected. Chain-Ray’s material database of more than 25,000 entries includes materials that have passed USP VI and ISO 10993 biocompatibility tests, or JIS Z-2801 formulated by the Japanese Industrial Standards (JIS). Antibacterial standard materials are also available, as well as medical plastic injection-grade materials with high mechanical properties and transparency. If you need to design and produce medical-related products, our material service department can provide the most complete support, from material consultation and sales, to product sample production all the way to final product mass production. Let Chain-ray eliminate the difficulties and complete the process within your desired timeframe.

When product designers need the advantages of multiple materials to meet product design needs, composite materials that combine the characteristics of two or more different materials are the best choice. In fact, we can often see composite materials in several aspects of our daily lives. For example, tires are made of rubber and carbon black, and concrete is made of cement and sand. The purpose of having a composite is usually to take advantage of the characteristics of different materials. To make up for any shortcomings, after selecting one certain material to act as a matrix, more than one other material will be added as a reinforcement. Soo in simple terms, the composite material is composed of a base material and a reinforcement. Take glass fiber, as an example. It has very good tensile strength and contains nylon, which is a highly temperature-resistant polymer. Therefore, composite materials with nylon as the base material and glass fiber as the reinforcing material have the dual characteristics of high temperature resistance and impact resistance. Additionally, It is worth mentioning that glass fiber can also be combined with a variety of different base materials like ABS, PP, PBT and PTT, and the resulting composite materials will then have different characteristics. When you consider thermal resistance, wear resistance, corrosion resistance, heat resistance, and other characteristics of the product at the early stage of the design, all you have to do is inform Chain-Ray of your needs, and we will try our best to find the most suitable composite material for you.

Plastic is the most widely used material for two reasons: (1) When the product needs to be mass-produced, the plastic material can better ensure that the product meets the considerations of consistency, repeatability, and economy; and (2) Plastic has the ability to be produced quickly, and its properties are easily to be changed, Plastic materials can meet specialized functional requirements for many types of products, such as: Outdoor products that need UV resistance, for which plastic composites are suitable Products with higher strength and toughness to avoid product breakage or chipping during use, for which plastic and rubber materials are suitable Flame resistance in order to comply with indoor safety regulations, in which case certain plastic products can prevent or delay burning In recent years, the application level of modified plastics has become wider and wider. Many well-known chemical companies in the world, from Saudi Arabia's SABIC and Germany's Covestro, to Switzerland's EMS group and Taiwan's Chi Mei (CHIMEI), each have their own specialization and research and development of modified plastic products. Now, fortunately, companies can choose to face the single window of Chain-Ray. In our material database, we have a selection of global materials that we’ll help you sort through. You won’t be limited in materials by what we manufacture, since we work with suppliers all over the world. You’ll also be given a plastic comparison chart, showing all candidate materials. From this, you can easily grasp the difference in properties and costs between plastic materials from different brands.

Though metal materials have many advantages, they are often a source of headaches for product designers. Metal materials are extremely sturdy and durable. Additionally, they have good heat dissipation and conductivity, and a unique appearance with the lustre of metallic. On the contrary, however, due to widespread oxidation and the corrosion of metal materials, each type has various characteristics. Depending on the material chosen, the yield strength, hardness, tensile strength, and more can vary, making it a challenge for product designers to select the correct metal materials.

Principle 1: We can accurately translate all customer needs into actual product specifications and technologies. Principle 2: Within the product design stage, Chain-Ray uses DFx, the idea of "Design for Excellence." Principle 3: From product design to mass production, Chain-Ray will provide you with one-stop full service
