In order to meet the latest market demands, MASIM, a high value-added film stretching system developed by French Masan, used the latest synchronous stretching technology and applied for a patent for the production of special films such as battery separators, barrier films and optical films. .
In order to cope with the increasingly refined market demand, French Marshall developed R&D in France. The tested and custom designed high-value film stretching system MASIM can stretch high-quality film under high-speed conditions to ensure film production. The highest quality, while guaranteeing reliability and safety. Through two-way simultaneous stretching of the film, the system can provide consistent results to ensure the best mechanical and optical properties of the stretched film.

The system can be used to produce ultra-high optical performance, good shrinkage index, high strength applications requiring thin films, such as: diaphragm, ultra-thin capacitive film, touch screen film and high barrier film.
The main features of the film stretching system MASIM are:
· No bottleneck in line speed: By installing large diameter chain clamp bearings, MASIM has improved the tensile force design and increased the mechanical speed up to 350 m/min for large-scale film production.
· The narrowest grip on the market, longitudinal stretch before grip: According to different film applications, Mashang clip width can be made 25mm, 30mm, 35mm and 45mm. The system has the narrowest grip on the market, MASIM can Flexibility, quality, achieve optimal performance by reducing the cutting edge to improve efficiency. According to the clamping distance multiplied by the pull, the ratio of the stretch ratio to calculate the length of the chain clip after longitudinal stretching is significantly reduced, can achieve a more excellent film properties indicators.
· Increased diameter of the chain clamp bearing: Increase the diameter of the chain clamp bearing to withstand greater tensile force (compared to the existing standard synchronous stretcher). The bearing compensates for film tension, chain system tension and guide chain Clip the corresponding move.
Chain clamp drive technology: For each chain clamp has a uniform tension, drive each chain clamp. High quality clamping is due to the chain clamp design, and reduce the risk of membrane rupture.
· Low energy consumption: Due to the unique chain clamp design, MASIM allows less stress than other synchronous tensioner chains under the same working conditions, thus reducing equipment energy consumption. Because the heating system design achieves better temperature uniformity in the oven Sex, also reduces the heating energy consumption than progressive stretching.
The new design of the film stretching system MASIM can be adapted to all draw ratios and the production of all types of films to the greatest degree. It has the characteristics of high flexibility and provides the narrowest width of the clip on the market today, which can make the width of the film more efficient. High. And the smallest grip width ensures the best quality of the final product. The optimized grip system can evenly stretch and reduce the broken film. All the chain clip drive of the system can optimize both side film indexes to ultimately increase the productivity. Purpose, with a maximum line speed of up to 350 m/min. French Masan believes that the film stretching system MASIM can provide the best solution for Chinese projects (end)
