Thickness gauge is a precision instrument used to measure the thickness of objects. With its non-contact or contact measurement method and high-precision detection capability, it is widely used in quality control, production monitoring, and safety inspection in multiple industries. The following are its main application industries and specific scenarios:
1. Manufacturing industry (metal/non-metal processing)
Metal products industry: used to measure the thickness of metal materials such as steel plates, steel pipes, aluminum foils, copper strips, etc., to ensure that the dimensions of raw materials and finished products meet standards, such as thickness detection of automotive steel plates and wall thickness monitoring of stainless steel pipes.
Plastic/Rubber Industry: Testing the thickness of plastic films, plastic sheets, and rubber products (such as tire treads and seals) to ensure product uniformity and durability.
Plate/profile industry: Measure the thickness of wooden boards, glass, ceramic boards, composite boards, etc., to avoid affecting subsequent processing or performance due to thickness deviation.
2. Automotive and Aerospace Industry
Automobile manufacturing: Testing the thickness of body steel plates, component coatings (such as chrome plating and electrophoretic paint), as well as the thickness of tires and car window glass, to ensure the safety and durability of vehicles.
Aerospace: high-precision measurement of the thickness of metal sheets and composite material layers (such as carbon fiber layers) on aircraft fuselage and wings, which directly affects the structural strength and lightweight design of the aircraft.
3. Electronics and Semiconductor Industry
Measure the thickness of semiconductor wafers, chip packaging layers, circuit board copper foils, and electronic thin films (such as lithium battery separators) to ensure stable performance and accuracy of electronic components.
Detect the glass substrate and film layer thickness of display screens (such as LCD and OLED) to ensure display performance and product quality.
4. Packaging industry
Testing the thickness of packaging materials for food, medicine, and daily necessities (such as aluminum foil, plastic film, and composite packaging film) must meet both packaging strength requirements and safety standards for food contact materials (such as thickness uniformity to avoid leakage).
5. Construction and building materials industry
Measure the thickness of steel plate, glass curtain wall, thermal insulation materials (such as thermal insulation cotton, foam board) and pipe materials (PPR pipe, steel pipe) for building to ensure the structural safety, thermal insulation and load-bearing performance of building materials.
Detect the coating thickness of coatings and anti-corrosion layers on walls and pipeline surfaces to ensure the durability and protective effect of buildings.
6. Medical Device and Pharmaceutical Industry
Used for thickness testing of medical equipment components such as metal brackets and catheters to ensure their biocompatibility and safety during use.
Measure the thickness of drug packaging (such as aluminum-plastic blister packs and medicinal glass tubes) to ensure the sealing and stability of drug storage.
7. Metallurgy and Steel Industry
Real time monitoring of the thickness of steel plates and strips in steel production processes such as rolling and forging, adjusting production parameters through feedback data, achieving automated production control, and reducing material waste.
