On-line thickness measurement system for plastic bottles and containers

The FocalSpec Bottle Wall Thickness Measurement System is a real-time wall thickness measuring system designed specifically for plastic bottles and containers. The system is installed on an existing conveyor downstream of a blow molding machine for 100% product inspection. The system’s MCP 100 sensors read thicknesses of each container in desired locations and stores the results in csv files. The results are displayed instantly on charts providing immediate feedback information for machine operator to quickly adjust and optimize blow molder settings after changeovers and during daily production. The system can also be set to automatically alert operators and to reject containers that exceed specified thickness limits with an trigger output for air blast blow-off.

Replacing laser – FocalSpec’s LCI offers superior accuracy in quality control for manufacturing

Line Confocal Imaging (LCI) is a unique and globally patented technology for carrying out quality controlling measures. It allows for measuring and testing on-line, so that the desired look & feel and quality for products is achieved. It also enables accurate and fast measuring not only in R&D, but also during on-line speeds in production.

Laser measuring, which is the most frequently used method for measuring, is capable of nearly identical accuracy and speeds compared to LCI. What it lacks in is the ability to measure transparent or shiny surfaces, or their combinations.

“One of the perks of LCI, is that anything with a refraction index can be measured. It can even detect separate layers in the scannable material, as long as they have separate refraction indexes. Speckle noise, which is a problem with laser scanning, is nonexistent when LCI is utilized”, Sauli Törmälä, president of FocalSpec says.

Utilizing Line Confocal Imaging to measure roughness and improve production

FocalSpec’s MicroProfiler MP900 can measure surface roughness at line speeds up to 150 meters per minute. The LCI technology allows the profiler to scan moving surfaces at the rate of 250 measurements per second. The LCI sensors use a measurement profile line which records 2048 3-dimensional raw data measurement points simultaneously.

The MP900 On-line roughness measurement system is a highly mobile, easy to set-up measuring device for companies producing cables, wires and medical tubes. The MP900 is receiving high volumes of sales in Asia, mostly in China, where it has been thoroughly tested and put into use by major cable manufacturers. FocalSpec has also developed a Line Confocal Sensor, LCI 1200. It is the tool of choice for 3D imaging surfaces, whether they’re dark matte, glossy or transparent.

LCI is suitable for a wide array of quality control measures

In a recent study made in the Tampere University of Technology, LCI was successfully used in preventing surface melt fracture in polymer cast film manufacturing.

LCI can be used in manufacturing to ensure a homogeneous extrusion process. It can be used to calculate the mean roughness, mean roughness depth and the mean width of profile elements. This can be utilized in the producing of medical equipment, for example medical tubes. It can also be used in achieving the wished look and feel for high end chargers for cell phones.

“The MP900 allows for measuring on almost any surface material, such as glass, metal and a wide variety of plastics. Combined with the LCI 1200, manufacturers can attain notable boosts in the quality of their end product”, Törmälä says.

About us

Company details

FocalSpec Oy utilizes unique Line Confocal Imaging (LCI) technology to develop and provide quality control sensors and systems for industrial customers and integrators world-wide. Line Confocal Imaging provides unique precision and resolution for speedy online measurements. LCI is a superior solution in several challenging application areas for 3D surface profiling and layer characterization, dimension and thickness measurements, gloss measurements and quality inspection. LCI is applicable for diffuse, glossy, colored and transparent surfaces. It can also be applied to thickness measurement of transparent objects, transparent coatings on non-transparent objects and total thickness measurement of non-transparent objects. The FocalSpec business is based on continuing development of applications for the patented optical technology, originally developed at the Technical Research Center of Finland (VTT). Operation is based in Oulu, Finland and Atlanta, USA. The company is owned by private investors, key employees and VTT Ventures Oy, a sole subsidiary of VTT.
