The world’s largest manufacturer of gypsum board, Taishan Gypsum Co. Ltd (The Taihe Group), has improved its production efficiency and product quality with an upgraded system utilizing HBM’s PMX modular industrial measuring amplifier system. The Taihe Group is part of the China National Building Material Group Corporation.
The challenge: Consistent quality level in gypsum board production
The Taihe Group has developed rapidly over the past few years and, for strategic reasons, decided to automate and replace its traditional manual production methods. Gypsum board is used in construction as partition and ceiling material because it is fireproof with excellent insulation and sound attenuation properties.
The Taihe Group’s strategy is intended to produce more consistent boards and demanded a system that could automatically measure and record the thickness and width of its products. Thickness needed to be between 8 to 12mm with a tolerance of less than 0.01mm while the width of boards needed to remain constant at 1200mm with a tolerance of 0.2 to 0.3mm.
