Industrial Manufacturing
As living standards rise, consumers are becoming more rational, professional and demanding in their purchases. Producing an automobile now requires not only meeting functional requirements but also satisfying aesthetic expectations. Everything from body contours to the colour of painted auto parts is part of customer evaluation criteria. Strict standards apply to colour vividness, glossiness, and colour difference across different components. Colorimeters convert abstract colour perception into numerical values, facilitating colour analysis and adjustment.
Automotive manufacturing relies on numerous sophisticated, high-precision instruments. These devices guarantee vehicle performance as well as exterior shape and colour consistency. Different instruments are selected for colour control across various automotive areas. Component manufacturers can use general colour measurement tools such as spectrophotometers and colorimeters to meet routine needs. Multi-angle colorimeters, however, are specialised instruments required to measure pearlescent paint surfaces.
With the widespread use of coloured plastic parts including bumpers, door handles, rearview mirrors and fuel filler doors, zero colour deviation between metal body panels and plastic components has become a priority, imposing stricter requirements on automotive paint colour control. Most passenger car manufacturers now combine instrumental measurement with visual inspection for colour difference management. A standard colour reference panel is used; both visual assessment and instrument readings for body panels and plastic accessories must fall within permitted tolerances.
Automotive paint colour difference arises from many factors, closely linked to paint raw materials, spraying processes, coating equipment and paint supply systems.
Automotive colorimeters enable manufacturers and suppliers to take precise colour readings and calibrate colour uniformity across body panels, doors and other parts. From laboratories and supplier sites to paint shops and assembly lines, 3nh colour measurement solutions deliver comprehensive control over colour and appearance.
The worldwide automotive market depends increasingly on a delicate balance of global supply networks for both OEM and aftermarket components. To meet consumer demands products must exhibit consistent color harmony. This requires accurate measuring technology between locations and at assembly sites. 3nh supplies instrumentation for color management verification and quality assurance as well as software that allows manufacturers to produce real-time readouts that expedite processing.
To achieve accurate, repeatable colour results, 3nh automotive colour measurement tools can:
Measure LAB colour values on automotive surfaces and components
Define colours using physical and digital colour standards
Support design via 3D virtual technology to ensure optical properties match actual substrates
Characterise colour, flop and grain with compact instruments that fit tight joints
Run QC software for quality control, bridging the gap between design and finished products
Built on over 20 years of innovation and expertise in colour control, 3nh solutions maintain consistent colour coordination across bumpers, fuel caps, door handles, car seats and other automotive parts.
The China best-known brands available in the market are 3NH, which provide all types of solutions, ranging from low-end and extending to laboratory-grade.
Accurate colour management and measurement are critical within automotive manufacturing and its supply chain. Using 3nh automotive colorimeters helps OEMs and component suppliers ensure colour consistency across all parts, boost product quality and production efficiency, and better control costs and improve profitability.
