Learn about customization
Instrument and Device Shell Industry knowledge

When customizing Plastic Instrument and Device Shell, choosing the right plastic material is a key step to ensure product performance, durability, and cost-effectiveness. First, clarify its specific needs and application scenarios. For example, understand whether the housing is exposed to high temperature, low temperature, humidity, corrosive chemicals, or ultraviolet light, whether mechanical properties such as impact resistance, pressure resistance, wear resistance, or high rigidity are required, and whether electrical properties such as insulation, antistatic, or conductivity are required. In addition, it is also necessary to consider appearance requirements such as high gloss, transparency, color stability, or surface texture, as well as environmental requirements such as recyclable, biodegradable, or compliance with environmental standards such as RoHS/REACH. Finally, it is also necessary to understand the customer's acceptance of material costs.
Common plastic materials include polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), polyamide (nylon, PA), polypropylene (PP), polyetheretherketone (PEEK), polyvinyl chloride (PVC), polyoxymethylene (POM), and polyphenylene sulfide (PPS). Each material has its own unique advantages and disadvantages and is suitable for different scenarios.
For example, PC has the characteristics of high transparency, high strength, impact resistance and high temperature resistance, and is suitable for housings that require high transparency and impact resistance, such as instrument panels and protective covers; ABS has high strength, impact resistance, easy processing and low cost, and is suitable for consumer electronics and household appliances housings; PA has the characteristics of high strength, wear resistance, high temperature resistance and chemical corrosion resistance, and is suitable for industrial equipment and automotive parts; PP is chemically resistant, high temperature resistant, lightweight and low cost, and is suitable for chemical instruments and laboratory equipment housings; PEEK is high temperature resistant, high strength, chemically resistant and wear resistant, and is suitable for high-end medical equipment and aerospace components; PVC is chemically resistant, flame retardant and low cost, and is suitable for chemical equipment and pipeline housings; POM has high rigidity, wear resistance, chemical corrosion resistance and good dimensional stability, and is suitable for precision instruments, gears and bearing housings; PPS is high temperature resistant, chemically resistant and flame retardant, and is suitable for industrial equipment housings in high temperature environments.
According to specific needs, matching is combined with material properties. For high temperature resistance, you can choose PEEK, PPS or PC; for corrosion resistance, you can choose PP, PVC, PPS or PEEK; for impact resistance, you can choose PC, ABS or PA; for lightweight requirements, you can choose PP or PA; for appearance requirements, you can choose PC or ABS; for environmental protection requirements, you can choose PP or PLA. In addition, you need to consider the processing properties of the material, such as injection molding adaptability, processing temperature and mold design, to ensure that the selected material is suitable for the injection molding process, has good fluidity and low shrinkage, and select the appropriate material according to the equipment capacity and mold design.
